OmniTek OTR 1001 User Guide, v3.0

A : Equipment Guide Introduction The OmniTek OTR 1001 is an extremely versatile instrument for video test and measurement. The base instrument is an image analyzer, offering picture monitoring and waveform, vectorscope, gamut and status displays. However, the OTR is offered with a wide range of instrument options, some of which enhance the facilities it offers as an image analyzer while other options add test signal generation facilities. Further options allow the OTR to be set up to carry out picture quality and audio quality assessments, a range of timing tests and physical layer measurements. As an image analyzer, the OTR 1001 can provide high precision waveforms, vectorscope and gamut displays; real-time picture monitoring; comprehensive SDI input status information; audio monitoring capabilities; and transport layer analysis including eye-pattern and jitter displays. (The options offered depend on the software options that are installed.) As a test signal generator, the instrument can generate a wide range of standard test patterns and zoneplates; play-out video images and sequences from disk (including 3D sequences), and add gain, noise, bounce and audio tones to the resulting test signal (again depending on which options are installed). It is also able to generate and add timecodes, WSS, video index and SMPTE 352 codes. The OTR also has the ability to freeze the screen display and to capture images from the incoming video The OTR 1001 is available in 1001c and 1001m versions. The OTR 1001c is designed to be driven from the control panel on the front of the instrument but both the OTR 1001c and the OTR 1001m may be driven using a mouse and keyboard. Most instrument features can be selected using either method but there are some facilities that are only available when a mouse is attached. For example, a mouse is needed to set up new screen layouts. However, once any layout has been recorded as a preset, it can be called into use from the control panel – without any need for a mouse. In designing the system, we have given close consideration to our existing customers and made the interface as familiar as possible to them, while also making it easy for users of other manufacturers’ systems by designing it to follow a similar methodology.

The exception to this is where an EYE_ option is added: in this case, the OTR system may need to be returned to have the necessary hardware factory-fitted. (Your dealer will advise you on this.) Extra software facilities are made available by providing an updated licence file, and again instructions will be provided alongside the new licence file. When installing new facilities, it is a good idea to check that you are using the most up-to-date version of the software. How this is done is described in Section A.5. (Details of the version you are currently using are given on the System page of the OTR’s Config window.) OmniTek OTR 1001 User Guide, v3.0

A-5

A.2 Installation The OTR 1001 is supplied with the software and any additional hardware that is required to support the instrument options that have been purchased e.g. AES and Eye/Jitter cards already installed. So after a couple of preliminary steps (see below), the job of installing the OTR 1001 is simply one of locating the instrument where you want to use it and attaching the appropriate cables.

Preliminary steps: Checking the Pack Contents Alongside the OTR 1001 in the OTR 1001 pack, you should find: Appropriate national power cord (UK/US/Europe/Australia) USB Stick (in the mini-box) Quick Start Guide Cards (in the mini-box) Note: This list is subject to change. A packing list for the OTR you have bought is included in the pack. Before starting to install the OTR 1001 for use in your facility, check that you have received all of items listed above. Note: Any additional boards that are required to support additional application options you have purchased will be already installed in the OTR 1001. We recommend saving the shipping carton and all packing materials in case you subsequently need to ship the OTR 1001 anywhere.

Mounting in a rack The OTR 1001 can be used mounted in a standard 19" rack.

Cabling The remaining task therefore to make the appropriate connections for the task it is to perform. The majority of these connections will be to the connectors on the back panel of the instrument, which are detailed in the following diagram and table. SDI IN 1,2

Adding the Graphics Display The graphics output from the OTR 1001 can be displayed by plugging a DVI monitor or a VGA monitor into the DVI-I Out connector on the back panel. Depending on the VGA monitor cable, this can either be plugged in directly or via the VGA – DVI cable included with the OTR. Note: A high-resolution computer monitor is needed when working with 3G video. SDI IN1

Display Resolution With a DVI monitor, the screen resolution is automatically set to the correct resolution for the monitor. However, with some VGA monitors, the OTR is not able to set the optimum resolution automatically and may even give no display at all. The point at which this might cause a problem is either the very first time you use the OTR or immediately after switching to a different monitor. If the screen resolution is poor or you don’t get any display, follow the steps given in Appendix IV of this User Guide.

Adding Mouse and Keyboard The OTR 1001 offers four USB ports through which a USB mouse, USB keyboard or combined USB mouse and keyboard may be plugged in – two on the front panel and two on the back panel. Devices plugged into any of these ports will be automatically recognised by the underlying Windows system and immediately made available for use, with the standard mouse actions of pointing and clicking having their usual effects.

Common Set-ups The following describes the set-ups needed for the two most common uses of the OTR 1001: Monitoring an SDI video signal Acting as a Test Pattern Generator It also describes some optional additions to the OTR 1001: Separate picture monitor for the generator External sync Monitoring an SDI video signal Setting the OTR 1001 up to monitor a video signal typically just requires a BNC cable from the video source to either IN 1 or IN 2. Where dual-link video is to be analysed, two such cables are needed – one for each link – one connected to IN 1 and the other to IN 2. The primary connection should be made to the IN 1 BNC, while the secondary connection should be made to the IN 2 BNC. Power Socket

Figure A-3: Rear view of an OTR 1001 showing the important connections when the OTR 1001 is being used to monitor a video signal. Note: The video signal can be passed through the OTR 1001 by connecting a BNC cable to the corresponding OUT socket, then selecting the Gen window and ‘running’ the ‘Pass Through’ pattern corresponding to the required input – see Section P.4. (Where the OTR 1001 doesn’t include a test signal generator, any signal fed into IN 1 is automatically made available on OUT 1; similarly any signal fed into IN 2 is automatically made available on OUT 2. The only additional step that is required is to set the Genlock to lock to the selected input as described in Section P.2.) Acting as Signal Generator Operation as a test signal generator (i.e. with either the GEN option or the GEN_BASIC option installed) just requires a BNC cable connected to either OUT 1 or OUT 2 (or both where a duallink signal is being generated). Note: The generated signal may be analyzed by the machine on which it has been created e.g. by plugging the other end of the BNC cable to one of the two IN sockets.

Optional Additions Adding a Picture Monitor for the Generator The OTR 1001 generator provides a non-broadcast grade analog signal on the Analog connector provided alongside the SDI inputs/outputs. To display the output, simply feed the Analog Out (ANA OUT) output to a suitable monitor. Note: A suitable analog cable can be purchased from your OmniTek dealer. Analog Out

Figure A-4: Rear view of an OTR 1001 showing the Analog Out connector. Adding an External Sync Where the OTR 1001 is used to analyze incoming video, it needs to be synchronised to that incoming video but for timing analyses (including assessments of the clock derived from the input stream), it needs to be locked to an external reference signal. You may also require the output from the OTR’s test signal generator to be synchronised with an external reference clock. The OTR 1001 can be linked both to the source of the reference signal and to other instruments using the same reference signal through the Reference Loop connectors on the back panel. Reference Loop

A.3 Power Up Note: The additional steps needed to run the OTR in ‘PQA Mode’ are described in Section S.2. The OTR should be operated from a single-phase power source, using the supplied power cord. The live conductor in this power cord is fused to protect against over-current conditions. It operates on an AC line frequency of 47 – 63 Hz, over the range 85 – 256 Volts, without the need for any configuration. A fully loaded system draws less than 100 Watts. For safe operation, the OTR 1001 must be properly grounded through the grounding conductor within the power cord.

Applying Power Connect the supplied power cord to the power connector on the back panel of the OTR 1001. When power is applied to the machine, the power button on the front panel will be lit and either showing as red, green or orangey-red depending on the state the machine is in. The power button is red when the OTR 1001 is powered but not running any software; green when the OTR application is fully loaded and running. The button may also flash green and orange. Should it do this, it means there is a problem such that pressing the buttons on the front panel no longer controls the software. To recover from this situation, press and hold the power button until the OTR starts its shutdown procedure. Once it has powered down, switch off at the back. Wait for the power button light to go out before switching on and re-loading using the standard Start-Up procedure (given below).

Start-Up Procedure To load the OmniTek OTR application: 1. Plug in the power cord and power from the mains. 2. Press the power button on the front panel. The OTR then loads the OTR 1001 application. As the software loads, the buttons on the front panel are lit in a moving sequence, demonstrating both that the machine itself is working and that the system can talk to each button. Note: Where mouse & keyboard are fitted, you can also load the OTR 1001 application from the Windows Desktop by clicking on the OmniTek OTR shortcut. When the software has loaded, the screen will show whatever display was on the screen when the application was last shut down using the Shut Down procedure described below. Note: If you encounter any screen resolution problems at this point, please turn to Appendix IV.

Shutting Down To close the OTR application (where mouse & keyboard are fitted): 1. If the application is currently in Full-screen mode, press ESC to select Windows mode. 2. Select the Exit option from the File menu. This returns you to the Windows desktop. To shut the instrument down : Press the power button on the front panel and take Shut Down from the Button Bar (white button). IMPORTANT: DO NOT shut down the machine by pressing and holding the power button unless absolutely necessary and DO NOT remove the power cord except when the power button on the front panel is red, otherwise you run the risk of corrupting the file system.

A.4 Display Modes The OTR 1001 offers a choice of display modes. The OTR 1001m is typically used in a ‘Windows’ mode in which the main display windows are shown in the middle of the screen windows with panels either side containing a range of toolbar controls.

Figure A-6: OTR screen in Windows mode: In this mode, the OTR’s windows follow the format of Microsoft® Windows and both they and the toolbars can be moved, re-sized, tiled, cascaded etc. using a mouse and standard Microsoft Windows techniques. (Note: Windows mode is intended to be driven using a mouse.) The OTR 1001c is typically used in a ‘Full Screen’ mode in which the entire screen is given over to one window display. Windows mode is intended to be used for setting up the OTR to give you the displays you require. Full Screen mode is intended for long-term observation of the images being processed, once the OTR has been configured as required. Some control is however available in Full Screen mode through ‘Button Bars’ (see Section B.3), a ‘right-click’ menu (described in Section B.1) and some special Keyboard controls (see Section B.1) Where the OTR is fitted with mouse&keyboard, it can be switched between these screen modes.

Switching between Windows Mode and Full Screen Mode Mouse & Keyboard only To switch between Windows mode and Full Screen mode (or switch back): Press ESC on the keyboard i.e. ESC toggles between these two display modes. Whether the OTR 1001 is working in Full Screen mode or Windows mode is one of the aspects of the system that is recorded when the OTR is shut down and automatically restored the next time the OTR is run.

A.7 General Care The OTR 1001 should be kept encased in the enclosure in which it is supplied or mounted in a standard rack unit. This will avoid dust getting into the hardware. We also recommend keeping the exterior of the OTR 1001 clean (see below). You should also have any damaged, worn or missing parts replaced as soon as possible through your OmniTek dealer. This will prolong the life of your OTR 1001. DO NOT try to clean or otherwise maintain the internal hardware of the OTR 1001. If there is an issue, consult either your OmniTek dealer or OmniTek support. IMPORTANT: Only qualified personnel should perform service procedures.

Cleaning The exterior of OTR 1001 may be brushed clean of dust with a soft-bristle brush or wiped over with a dry lint-free cloth. DO NOT use any abrasive compounds or solvents.

Changing the Battery The OTR 1001’s motherboard includes a battery that is used to maintain the system clock in the event of a power failure. This battery can be expected to last for at least two years. If the battery fails, it should be replaced with an identical CR2032 manganese dioxide lithium coin battery. Be careful to ensure that the battery is inserted with the negative side closer to the CPU. Note: The default BIOS settings for the OTR are held in a BIOS bin file and will be automatically restored when the instrument is reassembled with the new battery in place.

Using a Mouse As well as driving the OTR 1001 from the control panel (where fitted), it is also possible to plug in a mouse and keyboard and use these alongside the control panel to drive the OTR 1001. Operating with a mouse and keyboard gives the user both an alternative way of selecting features that can be accessed from the control panel and access to some features that aren’t accessible using the control panel controls. The OTR 1001 offers four USB ports through which a USB mouse, USB keyboard or combined USB mouse and keyboard may be plugged in – two on the front panel and two on the back panel. Devices plugged into any of these ports will be automatically recognised by the underlying Windows system and immediately made available for use, with the standard mouse actions of pointing and clicking having their usual effects.

Figure B-3: Rear view of an OTR 1001 showing the ports available for attaching a mouse and/or keyboard The OTR 1001 is PC-based and its interface broadly follows the control conventions of a standard Microsoft ® Windows® interface, with the PC’s mouse and keyboard being used for data entry and option selection. Items and options are therefore typically selected through a combination of positioning the cursor and single-clicking the left-hand mouse button. Where other actions are required, this should be clear from the description in this document.

Menus When the OTR is in ‘Windows mode’ (selected from the alternative Full Screen mode by pressing ESC), the Menu bar at the top of the OTR screen offers File, View and Windows menus. There is also a ‘right-click’ menu. All four menus are described below. Note: Some of the facilities offered below are only offered in Windows mode. File menu Load system default: Returns the OTR 1001 system to a standard state (Full Screen display mode, showing the View window in its default quadsplit arrangement with Input 1 selected). Load/Save presets: Calls up a list of available presets, from where you can select a preset to load, delete presets that are no longer wanted etc. Exit: Closes the application and returns to the underlying Windows operating system. The current screen arrangement and other current settings are restored the next time the application is loaded. OmniTek OTR 1001 User Guide, v3.0

B-3

View menu The View menu controls the display of the various toolbars used by the OTR 1001 application. In general, clicking on an entry to tick it causes the selected toolbar to be displayed. Similarly, clicking on an entry to clear the tick causes the selected toolbar to be closed. The Properties toolbars entry is slightly different in that there are individual Properties controls for each application window, plus an overall System Properties control. These controls may be individually selected in the associated submenu. These toolbars are typically displayed by default when the screen is in Windows mode. In Full Screen mode, they can be called up by using special key combinations (detailed in the section on ‘Keyboard Controls’, below). Details are given below in the section on ‘Toolbars’. Windows menu Full-screen: Selects Full-Screen mode (see ‘Display modes’ below). Help, Configuration, Gen, View: Control the display of these top-level windows. In general, clicking on an entry to tick it causes selected top-level window to be displayed. Similarly, clicking on an entry to clear the tick causes the selected window to be closed. The View entry is slightly different in that, where OTR systems are networked together, they each have individual View windows. These are therefore listed in a separate submenu. Note: The current version doesn’t include Help. Restore Windowed layout: Provides a quick route to a tidier window arrangement by replacing the current arrangement of windows and toolbars by one in which all the toolbars are displayed, arranged in panels on either side of the screen and the View, Gen and Config windows are resized to a standard size and placed in the top left-hand corner of the main display area with the window that is currently in use on the top. The windows and toolbars can then be re-positioned, re-sized etc. as required. Right-click menu Right-clicking with a mouse displays a context-sensitive menu. The following three entries always appear, as do two of View, Generator and Configuration (giving you a route to the alternative window displays). Home: Goes to the top-most level of the current display, at which no individual item included in the display is selected. Back: Used in hierarchical displays to go one step back up the hierarchy. Properties: Calls up the Properties control for the current window. The remainder depend on the window that is displayed and what the pointer was on when the mouse button was clicked. The example shown here is displayed when the View window is in its normal mode (as opposed to its Edit mode: see Section D).

OmniTek OTR 1001 User Guide, v3.0

Toolbars The OTR 1001 in Windows mode also offers a range of toolbars through which to call up the different facilities offered by clicking with a mouse. These toolbars are displayed either side of the main window. Some of these are applicable across the whole system; others only apply to particular window displays. The default is for all the toolbars to be displayed in a panel either to the left or to the right of the main display window – though all toolbars can be undocked from their default positions, moved and re-sized using standard Microsoft Windows techniques. The display of these toolbars is controlled through the View menu included on the main Menu bar (see above) but many of the options included in the other toolbars can be selected using particular keystrokes (see ‘Keyboard Controls’, below) To display a particular toolbar: 1. Display the View menu by clicking on View in the Menu bar. 2. Toggle the required toolbar between unticked (hidden) and ticked (displayed) by clicking on its name in the menu. What the different toolbars offer is outlined below. The order in which they are discussed works through the toolbars in their default order, starting with the toolbars normally shown to the left of the main display. Top-Level Windows Toolbar The Top-Level Windows toolbar lists the four main window displays offered by the OTR 1001 – View, Gen, Config and Help – together with a Freeze facility for capturing screen shots and SDI input stills. Left-clicking on the required window name brings that window to the front of the display and makes it the active window.

Navigate Toolbar The Navigate toolbar is used with more complex window displays to navigate hierarchies and menu structures.

Full/Multi Toolbar The Full/Multi toolbar enables the main data analysis window to be switched between showing multiple tiles (Multi) and showing one of these tiles full screen (Full). Subsequent selections of the Full option toggle between full screen display with and without the associated status/button bar. Inputs Toolbar The Input toolbar lists the input streams that are currently available and allows you to select the one you want.

OmniTek OTR 1001 User Guide, v3.0

B-5

View Tile Browser The View Tile Browser toolbar allows different analytical ‘Views’ of the input to be selected for display. It is described in detail in Section C.2.

Presets Toolbar Presets store particular combinations of settings and other selections, for easy recall on subsequent occasions. There are separate presets for the View and Gen windows, plus ‘System’ presets that implement specific combinations of View and Gen window layouts. See Section B.4 for further information. Presets are identified by number – 1, 2, 3 etc. and the Presets toolbar enables you to select the Preset you want to use. Presets 1 – 9 are selected by simply clicking with your mouse on the corresponding number. To select Presets 10 and above, click on *, click on the digits of the required number, then click on Enter. Properties Properties controls such as the one shown here are used to configure screen displays. A separate Properties control is provided for each top-level window, showing how that window and its contents are currently configured and allowing that configuration to be changed. Any changes that are made within the control have immediate effect. The window associated with any Properties control is indicated in the title bar and in the tab at the bottom of the display, which can also be used to select the required display where the controls are overlapped as shown here. Further information about Properties controls is given in Section B.3.

B.3 Window Displays The OTR 1001 application has four ‘top-level’ window displays, used for different areas of the system’s operation as follows: ‘View’ window – used for Image Analysis ‘Gen’ window – used for Signal Capture/Generation ‘Config’ window – used for System Configuration and Version information ‘Help’ window – used for On-screen Help (not supported in the current version) To make the most efficient use of the screen area, the above windows are overlaid one on top of another. They are also normally shown ‘full frame’ without any of the usual framing associated with Microsoft Windows. However, where the OTR 1001 is being used with a mouse and keyboard, the OTR 1001 can be used in a ‘Windows’ mode (see below) in which the basic controls are offered as a set of toolbars and the windows have the normal Windows handles. To select any of the main window displays: Control Panel

Mouse & Keyboard

To select any of the main window displays: Press the corresponding button from the group immediately to the right of the numeric keypad. (Note: The Help button is to the left of the numeric keypad.)

1. Check that the Windows Toolbar is displayed (selected via the View menu). 2. Click on the name of the required window in the Top-Level Windows Toolbar

Other displays are called up on screen as a consequence of selecting options within one of the main windows. Note: The Config window is divided into ‘pages’ covering different aspects of the OTR 1001’s system configuration. So inspecting or changing any detail of the system configuration involves first calling up the Config window, then selecting the appropriate page of this window.

Status Bar The window displays may also include a Status Bar such as the one shown here, giving appropriate information for example about the video currently being received on the OTR’s IN ports together with a clock and the preset that is currently selected (see Section B.4). The Audio data indicates the channels on which audio is present (P) in the order Channel 1 – 16.

Figure B-5: Sample Status Bar display

B-10

OmniTek OTR 1001 User Guide, v3.0

Button Bar Associated with each display is a Button Bar. In the Gen and Config windows, the Button Bar is always shown at the bottom of the screen. In the View window, the default arrangement is for the Button Bar to temporarily take the place of the Status Bar at the bottom of the screen but there are other options. (For details, see Section C.1.) The Button Bar is a command bar and it provides direct access to some commonly-required actions. In particular, several Button Bar options provide shortcuts to settings within the Properties control (described below). In most cases, successive presses of the Tile button cycle through the possible options while pressing and holding the Tile button brings up the Properties control with the focus on the selected feature. The options shown depend on the window being shown and the action being carried out. A sample Button Bar is shown below.

Figure B-6: Sample Button Bar The standard colouring for any button is a dark grey, changing to a lighter grey when the feature it selects is not currently available. Where options on the Button Bar turn on or turn off particular features, the button is additionally highlighted (copper-coloured) when that feature is currently selected.

Picking out Items to work with Throughout the OTR 1001 application, items in windows or menus are picked out to work with by moving the ‘focus’ of the window to the required item, after which it may be necessary to further select the item in order to either change it or activate it. The item that currently has the focus on it is identified by blue highlighting, which is replaced by copper-coloured highlighting when the item is selected for further work. Basic Navigation: Control Panel

Mouse & Keyboard

To move the focus to any item on the current window (blue highlighting), Twist the GENERAL knob on the Control Panel.

Scroll the thumbwheel on the mouse until the required item is selected. Alternatively, click on the item then press the Backspace key.

To select an item for further work (copper-coloured highlighting) Move the focus to the item as described above, then push the GENERAL knob.

Simply click on it.

Note: There is no reason for concern if currently nothing on the screen is shown either as having the focus on it or as being selected. Simply turn the GENERAL knob and a coloured boundary will appear as the focus moves from one item to another.

OmniTek OTR 1001 User Guide, v3.0

B-11

Navigating around hierarchical structures Several OTR 1001 displays have a hierarchical structure to them. The steps generally used to navigate these structures are given below. (Note: Where special steps are needed to navigate a hierarchical display, these steps are explained alongside the description of those displays.) Control Panel

Mouse & Keyboard

To navigate a hierarchy: 1. Turn the GENERAL knob to move the focus from item to item at the current level. 2. Push the GENERAL knob to move down into the next level of the hierarchy. (This works until a single item is reached at which point, pushing GENERAL selects the item.) 3. Move one step back up the hierarchy by pressing the BACK button. 4. Move directly to the top of the current hierarchy by pressing the HOME button.

1. Select the required item by clicking on it. If this selects other items alongside the required item (i.e. a higher level of the hierarchy), click again until just the required item is selected. 2. Move one step back up the hierarchy by taking the Back option from either the right-click menu or the Navigate toolbar. 3. Move directly to the top of the current hierarchy by taking the Home option from either the right-click menu or the Navigate toolbar.

Window Properties Each window offers a number of choices about how the window itself and the items within that window are displayed. The choices that are made are referred to as the ‘Properties’ of the window and each window has a Properties control through which the various selections can be made and displayed, while some of the more common settings are offered as Button Bar options. Control Panel

Mouse & Keyboard

To display a window’s Properties control: Display the required window (if not already displayed) and press the PROPS button. (Press PROPS again to close up the display.)

Right-click on the required window and take the Properties option from the menu that is displayed, or Select Properties from the View menu, then select the appropriate View option from the sub-menu that is displayed.

Note: In the View window, access to some of the settings in the Properties control is provided through options on Button Bars, providing a useful short-cut for a range of common settings. An example Properties control is shown below. The window to which the Properties relate is shown in the title bar. (Note: The View window is sometimes View 1 because, in future versions, where OTR systems are networked together, the View windows associated with other OTR systems will be identified as View 2, View 3 etc. You should also note that the width at which the Properties control can vary depending on the layout of the current display.

B-12

OmniTek OTR 1001 User Guide, v3.0

Figure B-7: Sample Properties controls – Full View and Multi View The properties listed at the top of the display set some overall details either about the window and its Properties control. The properties of the items within the window display appear towards the bottom of the display. The range of properties associated with any item entirely depend on the type of item. As in other parts of the OTR’s operation, copper-coloured/blue highlighting is used to indicate the current focus within the Properties control and this focus is moved by twisting the GENERAL knob. If an item is selected within the main window display when the Properties control is called up, the focus will be on this item. Similarly, if the Properties control is called up as a result of selecting an option from the Button Bar, the focus will be on the selected setting. The aspects set through the Properties control are arranged in a collapsible hierarchy with [+] or [-] symbols alongside the ‘headings’ so that you can readily arrange to see just those details that you want to see. The basic procedure for setting properties is as follows: 1. Display the Properties control for the window you are working on. 2. Use the [+] and [-] markers to open/close sections of the display as required. 3. Make any adjustments that are necessary to the various settings shown.

B.4 Presets Particular combinations of settings and other selections can be captured for recall on subsequent occasions by recording these as Presets. Three types of Preset can be recorded: View Presets; Gen Presets and System Presets. View Presets record the detailed layout of the View window (including all the settings in the View Properties). Gen Presets record all the settings in the Gen properties, together with the details of the ‘patterns’ (images, sequences, line patterns and zone plates) that are currently loaded for play-out but not the source files for these patterns System Presets record all the details about the current system that would be recorded by a View Preset and a Gen Preset, together with such things as the positioning of the different windows when the OTR 1001 is used in Windows mode, which toolbars are displayed and where they appear on the display. Presets are identified by a number which may be used to select the required Preset (see below). When a Preset is selected, all the settings that the Preset records are replaced by the values etc. that are recorded in the Preset, So when a View Preset is selected, it populates the View window with the saved combination of tiles. It also switches the selected input stream back to the one that was selected when the Preset was recorded. (It doesn’t, of course, change the data stream on the selected input.) Similarly, when a Gen Preset is selected, the Gen properties are set to match the ones recorded in the Gen Preset and the patterns are replaced by the set of patterns that were in place when the Preset was recorded. Note: It is up to the user to ensure that the source files to which these patterns refer are available in their expected locations. When a System Preset is selected, both the View window and the Gen window are changed to reflect the settings recorded in the Preset. It also puts the windows in the positions they had when the Preset was saved and switches the selected input stream back to the one that was selected when the Preset was saved. (It doesn’t, of course, change the data stream on the selected input.) The number of the currently selected View Preset is displayed on the Status Bar, followed by an asterisk when the layout has been changed from the recorded version in some way. A number of Presets are supplied alongside the OTR 1001 software. These can either be replaced or added to by recording further Presets (see below).

Using Presets from other OmniTek systems As well as using Presets set up and saved on your own system, you can also use Presets both from other OTR systems and from OTM systems. The option that enables you to do this is the Manage Disk option offered when you call up the list of Presets (as well as at other points within the OTR application). Taking this option displays a Manage User Files dialogue with options for Importing, Exporting or Deleting the different types of file that you may have in your User area, which include Presets. Further information is given in Section U.

B-14

OmniTek OTR 1001 User Guide, v3.0

Preset Selection Presets may be called up from a list of all the Presets that have been set up. This list also offers a Manage Disk option that can be used to remove unwanted Presets or to exchange Presets with another system. The alternative way of selecting a View or Gen Preset (but not a System Preset) is by giving the number of the required Preset. Control Panel

B.5 File Selection Several actions in the application involve the selection of a file stored on disk. Where the OTR is being used with a mouse and keyboard, a standard Windows file selector is shown through which to select the file you require. Where the OTR is being used without a mouse and keyboard fitted to it, a special form of file selector is used (shown below), together with a dedicated button bar. Together, these allow files to be picked out using the buttons of the control panel. The main display shows a list of the items (disks, folders, files) present at the current point in the file hierarchy. Note: The “..” entry at the top of the listing (where shown) represents the ‘parent’ directory.

Button Bar

Figure B-9: Sample File Selector and associated Button Bar (below)

Toggle select switches the current item between unselected (clear) and selected (ticked). Where the item is a folder, the whole contents of that folder are selected. Toggle select all switches all the items in the current folder between unselected (clear) and selected (ticked) or vice versa, depending on the current setting of the individual items. OK is used once you’ve selected the required file(s) to close the file selector and work with the selected files. Cancel closes the File selector without making any changes.

Control Panel To select files: 1. Navigate to the folder containing the required file(s). To step through different folders, move the focus to the appropriate folder name (by turning the GENERAL knob), then push the GENERAL knob to enter that folder. 2. Select individual files by moving the focus to each file in turn and pushing the GENERAL knob to tick it, or select all the files in a folder either by using the Toggle select all option (Yellow button) or by moving the focus to the folder name and taking the Toggle select option from the Button Bar (/White button). 3. When all the required files are ticked, select OK from the Button Bar (Cyan button).

B.6 Saving Files Some actions involve saving a file to disk. In some cases, the file is saved automatically in a standard location and under a standard name; in others, the user needs to select both where the file is stored and its filename. Where the OTR 1001 is being used with a mouse and keyboard, a standard Windows file selector is shown through which to set these details. Where the OTR 1001 is being used without a mouse and keyboard fitted to it, a special form of file selector is used (shown below), together with a dedicated button bar. Together, these allow the required details to be selected using just the buttons of the control panel.

C.1 Overview Selecting the View Window Control Panel

Mouse & Keyboard

To display the View window: Press the VIEW button on the Control Panel.

Click on View in the Windows toolbar. Note: If this toolbar isn’t displayed, tick Top-level Windows toolbar in the View menu)

Definitions The View window is divided into ‘Tiles’, each showing a particular aspect of the video under test (referred to as a ‘View’). For ease of selection, each View is allocated to a ‘Category’. ‘Views’ and ‘Categories’ are explained further below. Views The basic graphical elements that can appear on the OTR 1001’s View window are referred to as Views. Each View shows the results from a separate analysis tool and may include pictures, audio meters, waveforms, etc. Categories Views are organized into ‘categories’, each based around a particular type of data analysis offered by the OTR 1001. The principal categories are: WFM (Video waveforms) VECTOR (Vectorscope) PICTURE (Video image) AUDIO (Audio displays such as PPMs) GAMUT (Component gamut, CIE Colour Chart) STATUS (Status information, pixel data) TIMING (System timing, A/V Delays etc.) PHY (Transport layer measurements such as eye height and jitter) Each category can have any number of members (including 0), one of which will be the current default. For example, the AUDIO default might be the PPM display, while the STATUS default might be the ‘DataView’ pixel data display (where installed). Initially, some categories will just comprise the View after which the category is named, some may be empty while others may include additional Views depending on which instrument options have been installed. For example, where the OTR 1001 includes the VIEW_DATA option, the STATUS category will also include the DataView display. The labels on the ‘Tile’ buttons (WFM, etc.) each represent a different category.

Basic Screen Layout The default layout for the View window comprises four tiles, arranged in the simple ‘quad split’ shown below. This allows the results from up to four different monitoring tools to be displayed simultaneously.

Figure C-2: Standard Quad-Split Layout. It is also possible to set up custom screen layouts offering more complex arrangements of tiles (see Section D). A mouse is required to set such layouts up but, once in place, the Control Panel can be used to call up the different layouts. The tiles are referred to in terms of the View they show. So, for example, the screen shown above comprises an Audio PPMs tile, a Picture tile, a Waveform tile and a Vectorscope tile. Each tile can readily be replaced by one showing a different View. It is also possible to select any tile and show the View it contains full screen. (These actions are described in Section C.2.) Different combinations and arrangements of tiles may be saved for re-use on a subsequent occasion by recording these as Presets. (These actions are also described in Section C.2.). Optionally, a ‘Tile info’ line can be shown at the top of each tile, detailing the View that is displayed and the input that the display relates to. Whether this information is shown is set through the Properties control (see Section C.2), and is also saved as part of each Preset. Note: If a tile isn’t big enough to show the entire display, the tile will be shown with scroll bars. With a mouse, these scroll bars can be simply dragged to show the part of the display you are interested in. The bars can also be moved by pushing the corresponding HORIZ or VERT knob on the Control Panel, then twisting to make the required adjustment. (Push the knob a second time to cancel this action.)

Status Bar Where the View window includes a Status Bar, this gives brief details of the inputs that have been detected, together with a thumbnail of the video being received, a clock and the number of the preset that is currently selected (see Section B.4). The Audio data indicates the channels on which audio is present (P) in the order Channel 1 – 16.

Figure C-3: Example View Status Bar. Button Bar Associated with each display in the View Window is a Button Bar offering access to up to eight commonly-required actions or settings.

Figure C-4: Sample Button Bar There are three modes of operation for Button Bars in the View window, selected through the Soft keys mode section of the View Window’s Properties control:

Figure C-5: Soft keys settings within the View window’s Properties control. Normal: In this mode, when the Tile is selected, the Button Bar is displayed over the part of the screen normally occupied by the Status Bar. The Button Bar then remains displayed until it is either actively cleared from the screen (see below) or it times out (again, see below). Side-by-Side: In this mode, the Button Bar associated with the View on the current tile is permanently displayed in the left-hand half of the area normally occupied by the Status Bar, while a compressed version of the Status Bar is displayed in the right-hand half. Per Tile: In this mode, the appropriate Button Bar is permanently displayed at the bottom of each tile. Note: The Side-by-Side and Per Tile modes are principally intended for use where the OTR is used with a mouse and keyboard, while the Per Tile mode is intended for use with larger monitors.

C.2 View Window Operations This section describes some general actions that are carried out on the View window. Selecting the Views to display Switching between Full screen and Multiple tile display Setting tile and/or window properties

View Selection Any tile can readily be replaced by one showing a different View. The key factor is the category to which the required View belongs. Note: Where the same View is displayed by more than one tile, the Views are independent copies in order to allow the tiles to have different display properties. You should also note that some types of display – specifically waveforms, the vectorscope, the CIE Chart, Eye and Jitter displays – make significant use of resources. You will always be able to select whichever View you want where a tile is displayed full screen but more complex selections may not be available in a multi-tile display. Control Panel

Mouse & Keyboard

To display the required View: Steps when the category is known: 1. Move the focus (blue box) to the tile that you want to replace. (If a Button Bar is shown, press either OTHER or BACK.) 2. Press the Tile button (below the screen) corresponding to the required category. 3. The View shown then switches the most recently used View within that category. If the View that is selected isn’t the one you want, keep pressing the Tile button until the required View is displayed (cycles through the Views in that category). Note: If you select a category for which no Views are currently installed, the tile simply doesn’t change.

In all cases: Either: 1. Click on the tile that you want to replace. 2. Select the View you require in the View Tile Browser. Or: 1. Right-click on the tile that you want to replace. 2. Select Replace Tile in the menu that appears, then use the associated submenus to select first the category of View and then the actual View. The View that is currently displayed as replaced by the View you select.

General steps: 1. Move the focus to the tile that you want to replace. (Again, if a Button Bar is shown, press either OTHER or BACK.) 2. Press and hold any of the Tile buttons. This displays the View Tile Browser with the cursor on the category corresponding to the button you pressed. 3. Use the GENERAL knob to scroll through the available Views and select the required View. The View currently displayed is then replaced by the selected View. C-6

The View Tile Browser

Figure C-6: View Tile Browser. The View Tile Browser provides access to all the various Views that are available, organized into their categories, and allows you to pick the one you want in the current tile. Control Panel

Mouse & Keyboard

To display the View Tile Browser: Press and hold any of the Tile buttons (WFM, VECTOR etc.).

The View Tile Browser is displayed by default, but if it has been closed it can be displayed by ticking View tile browser toolbar in the View menu included on the screen’s menu bar

The top level of the Browser comprises a list of the categories that have been defined. To display details of the Views that have been allocated to a particular category : Move the focus to that category

Click on the [+] adjacent to the category name

When the Browser is displayed, the focus is automatically on the category from which you called up the Browser. Views are generally picked out by expanding the appropriate category then selecting the required View but the current default View within a category can be picked out by selecting the category. Note: If you select a category for which no Views are currently installed or a View that is not currently available (shown greyed out), the tile simply doesn’t change.

Full/Multiple Tile display Views can be displayed full screen (and subsequently switched back to a multi-tile display) using the FULL and MULTI buttons or the Full/Multi toolbar. On versions of the OTR 1001 with a Control Panel, either the FULL or the MULTI button is lit to indicate the mode that is currently selected. Control Panel

Mouse & Keyboard

To show a tile full screen: Move the focus to the required tile and press the FULL button. Press the FULL button again to toggle between showing and hiding the Status Bar/Button Bar at the bottom of the screen.

Click on the required tile, then take the Full option from the Full/Multi toolbar or press the + key of the keyboard’s numeric keypad. Click on Full or press + again to toggle between showing and hiding the Status Bar/Button Bar at the bottom of the screen.

Note: If no focus is shown (e.g. after selecting HOME), selecting FULL will result in the previously selected top-level View being shown full screen, automatically resized to fit the aspect ratio of the screen. To return to multi-tile display: Press the MULTI button.

Select the Multi option from the Full/Multi toolbar or press the – key of the numeric keypad.

The multi-tile display will show any changes you have made in full screen mode, unless there is a resource conflict in which case it will revert to the previous multi-tile display.

2. Make any changes you require within that control. The entries that set overall details are listed towards the top of the Properties control. Show all tiles: This option sets whether the Properties control shows details of every tile of the current display or just the one that is currently selected. Navigate flat mode: Ticking this option directs the OTR 1001 to ignore any hierarchy in moving the focus between the Views on the screen. Soft keys mode: Selects between the various options for showing Button Bars (see Section C.1). Tile info line: Sets whether brief details of the View and the input it relates to are permanently shown above each tile. Edit mode: Controls the granularity of the grid used either in setting up a new screen layout or in changing an existing screen layout (see Section D). Audio Monitor: Controls the volume at which audio is played back. (See Section K.9) Inputs: Sets/displays aspects of the input streams that apply to more than one View, such as the current position of the crosshair cursor. Shared Waveform Markers: Allows the definition of additional time and amplitude markers displayed across all waveform displays to aid comparison. (See Section E.3)

Setting Tile Properties The properties relating to the current range of tiles are listed in the section of the Properties control starting at the heading ‘Tiles’, and can be changed by editing the details shown in the Properties control. However, the first place to look when you want to change some aspect of a tile is the Button Bar because the Button Bar typically offers short-cuts to the most common settings associated with the selected View. In particular, some Button Bar options directly switch controls on and off (these options are given a copper-coloured highlight when the control is ‘On’). Other Button Bar options cycle through the possible settings, while on an OTR 1001c, pressing and holding the associated colour button calls up the Properties control with the focus already on the required setting. Control Panel

Mouse & Keyboard

To set any property of a tile: 1. First check the options in the Button Bar. (If the Button Bar isn’t shown, push the GENERAL knob on the tile.) 2. If the Button Bar includes the required property, take that option – otherwise press the PROPS button and make the required setting directly within the Properties control.

1. First check the options in the Button Bar. (If the Button Bar isn’t shown, click on the tile.) 2. If the Button Bar includes the required property, take that option – otherwise make the required setting directly within the Properties control.

Note: The properties listed in the Properties control reflect the current View window display. So if the window currently shows one tile full screen, the Properties control will just show the settings for that tile. What is displayed is also subject to the setting of the Show all tiles option listed at the top of the control. If this option is ticked, the settings of all the tiles currently on the screen are displayed; if it isn’t ticked, information is just shown about the tile that currently has the focus on it.

C.3 Video Stream The OTR 1001 supports a range of possible sources for the video stream to analyse. The main option is provided by the two SDI inputs included on the back panel of the OTR 1001. These are provided by the left-most pair of BNCs of the group of four that appear on the same card as the Analog connector. Each of these inputs can supply one or more video stream to analyse. SDI Input 1

ANA OUT

Figure C-8: The SDI Input (and Output) Connectors. Further inputs are available where the instrument includes a Jitter card. Where the system includes either the GEN or the GEN_BASIC option, it is also possible to set the OTR 1001 to analyse the output from its own test signal generator. Depending on the options installed, the OTR 1001 has the potential to analyse video delivered in a wide range of standards from the PAL and NTSC SD standards (supported as standard by all implementations of the OTR 1001), through to HD, 3GA and 3GB standards. The OTR 1001’s View window typically displays the results of analysing video on one particular input and, when a different input is selected, all the displays instantly switch to the selected input. But where one of the Simultaneous Monitoring options is installed, it is possible for two or more video streams to be monitored at the same time. This is explained in Section O.

Video Stream Selection Note: This section describes how to select a video stream to analyse from among those currently offered. As supplied, the system is configured to just offer video from the two SDI inputs. How to configure the OTR 1001 to offer the input from an installed Jitter card is explained in Section T (System Configuration). Similar steps may also be used to configure the OTR 1001 to analyse the output from the built-in generator, though there is the alternative of using a cable to feed the generated video from an SDI output to one of the SDI inputs. Once the OTR 1001 is suitably configured, the steps given here can be used to select the input you require. The OTR 1001 maintains a list of the input streams that are currently available for analysis in its Inputs toolbar. Precise details of the different services to the inputs are given on the Video Inputs page of the Config window (see Section T.4). Note: References to stream 2 (where shown) refer to the second video stream that is offered by 3G Level B Dual-stream video. Other video standards only offer a single video stream on any input. Selecting the input that is analysed is ultimately a matter of picking the required input from Inputs toolbar. However, it can also be picked out by giving its Input number, which corresponds to its position in the Inputs toolbar (starting with Input 1 at the top). Alternatively, where a mouse and keyboard are fitted to the OTR, the input to be analysed in a particular tile can be selected by dragging the relevant Picture icon on the Status Bar to the tile.

Or: Drag the Picture icon for the required input from the Status Bar to the tile.

Figure C-9: Inputs toolbar and the alternative right-click Set Input option. The input stream that has been selected may be seen by setting the Tile Info Line option in the Properties control to Permanent. Note: If the OTR has difficulty in locking to the input you select, try setting it to Ignore Smpte (see ‘Input Video Standard’, below) as the problem could just be that the SMPTE packet has become corrupted.

Input Video Standard The OTR is supplied set-up to automatically determine the input video standard. Where the input stream includes a SMPTE 352 packet, the input video standard will be taken from this. Otherwise, the OTR will make its own determination of the input video standard. If required, the OTR can be set to ignore any SMPTE 352 packet and always make its own determination of the video standard. Alternatively, you can force a particular input video standard to be selected. Note: Whether the input video standard has been selected automatically or forced can be seen from the Status displays (see Section E.6 & E.7) where the details of the selected video will either show Format (Auto) or Format (Manual).

Mouse & Keyboard

To freeze the display: Press the FREEZE button

Select Freeze from the Top-Level Windows toolbar.

The display remains in Freeze mode until such time as either the FREEZE button/the Freeze option is pressed/selected again. This action causes a bitmap of the screen display at the moment Freeze was selected to be captured and displayed in the VIEW window. It is then possible both to switch between this bitmap and the live VIEW window display and to save a copy of this bitmap as a file on disc. Currently, this facility can only be used to capture VIEW window displays, but it may in future versions be extended to also capture Gen window and Config window displays. While in ‘Freeze’ mode, the VIEW display has a special ‘Freeze’ Button bar.

Figure C-10: Freeze Button bar. Show Bitmap: Switches between displaying the captured bitmap (shown when this option is highlighted) and the live-input display.

D : View Screen Layout The quad-split screen used by default for the View window is simply one possible screen layout. Where a mouse is attached, other layouts may be set up to the user’s own specification. Moreover, when recorded as ‘Presets’ (see Section B.4), these layouts then become as easy to call up as the default quad-split. This section describes how to set up a new layout and how to save this layout for future use.

D.1 Overview A new layout is created for the View window by modifying the layout you are currently using. Close

Move left and stretch

Close

Move left and stretch

Add new tile

Figure D-1: Example set of changes To make the required changes, you need to put the View window into its ‘Edit mode’. In this mode, the View window continues to offer the same basic facilities as it does in its standard display mode (e.g. switching the View shown on any tile and setting tile properties) but the tile that is currently selected isn’t simply outlined with a coloured box. Instead it is shown with Microsoft Windows-style handles which allow the user to move the tile, re-size it or delete it. New tiles can also be added in Edit mode. In outline, the steps used to set up an alternative screen layout are as follows. A mouse is required for many of these actions. Indeed, it is not possible to enter Edit mode without a mouse. 1. Put the screen into Edit mode. 2. Close any tiles that are not required. Alternatively, add further tiles (there are two ways of doing this: see below). 3. Set the size and position of all the various different tiles shown on the screen. 4. Leave Layout Edit mode. 5. Check that the different tiles of the display are set to show the Views that you require. 6. Record the layout as a View Preset (see Section B.4). If the new layout is not recorded as a Preset, it will be lost the moment you either make any further changes to the layout or call up another View Preset.

D.2 Selecting Edit Mode Mouse & Keyboard To enter Edit mode: Check that the View window is set into multi-tile mode, then right-click with the mouse anywhere within the View window. Then left-click on the Edit mode option in the menu that is displayed.

Figure D-3: Right-click menu outside Edit mode Right-clicking again will show a tick beside the Edit mode option to show that this mode has been selected To leave Edit mode: Right-click then left-click on the Edit mode option again, this time clearing the tick. When Edit mode is first selected, there may be no obvious change in the appearance of the screen. The selection of Edit mode becomes obvious when a tile is selected. The selected tile is then shown with Windows-style bars and handles ready to be resized, moved or closed as required. Note: When editing a layout, you should be aware that elements of the display may be present but not visible. For example, a closed caption overlay may be specified for the Picture display but not be visible because the video that is currently being analysed doesn’t include a text service. D-2

D.3 Changing the Range of Views Displayed Once in Edit mode, the range of Views that make up the display may be changed through a combination of: Switching what is shown in the current tiles, and either Closing tiles that you no longer require, or Adding any extra tiles that are required. Switching the Views Shown The View shown in any tile may be replaced by another in exactly the same way as this is done outside Edit mode (details given in Section C.2). In particular, the required View may be selected by right-clicking on the tile and taking the Replace tile option from the menu that is displayed (as shown here).

Adding Tiles Further tiles may be added to the layout either by using the Insert tile option included in the rightclick menu when in Edit mode, or by dragging the required Views from the View Tile Browser. Mouse & Keyboard Using the Insert tile option: 1. Right-click to display the right-click menu. 2. Select the Insert tile option. 3. Select the required View from the list of categories and Views that is displayed.

Figure D-6: Right-click menu showing Insert tile option The View you select is then added to the screen, occupying the quarter of the screen in which you right-clicked to call up the Insert tile option. The new tile can then be re-sized, positioned etc. alongside all the other window tiles (see below). Its display properties can also be set through the Properties control. Adding a new tile by dragging: 1. Display the View Tile Browser (for example, by pressing and holding the Tile button for the category of tile that you want to add). 2. Select the required View in the View Tile Browser and drag it to one of the tiles already on the display. The OTR 1001 then creates a new tile over the tile you selected.

Drag to re-position

Figure D-9: Dragging a tile’s top bar to re-position it. Where tiles overlap, the sides and corners of one tile may be hidden by another. In order to adjust the size or position of the tile that is partially hidden, you need either to bring this tile to the front or to send the other tile to the back.

Individual tiles can be brought to the front or sent to the back as follows: Mouse & Keyboard To send to front/back: 1. Select the tile that you want to affect. 2. Right-click anywhere on the display. 3. Take the option to Send to back or Bring to front as appropriate.

Snapping into position To aid the process of aligning the different tiles, the OTR automatically ‘snaps’ the edges of the tile you are resizing/re-positioning to the edge of the adjacent tile once the edge gets close to this.

Figure D-10: Right-click menu when in Edit mode

Edit mode also offers a grid to which tiles may be aligned. Enabling this grid typically makes it even easier to put the tiles into a neat, ‘tiled’ arrangement.

Figure D-11: Grid settings with the Properties control The grid is enabled by ticking the Enable grid option within the Edit mode section of the View window’s Properties control. This section also includes a Count setting that sets the granularity of the grid to which the tiles are aligned by defining the number of sections into which the ‘working’ area of the screen is divided both horizontally and vertically. (This working area doesn’t include the area reserved for the Status Bar/Button Bar.) Larger values of the Count correspond to a finer grid.

D.5 Saving the New Layout The layout you create using the above steps will be the one used until you either change it further or call up a View Preset. At that point, the layout may be lost: calling up a View Preset automatically changes to the View window layout to the one that was in place when the View Preset was recorded. To have the layout you have created available for future use, it needs to be recorded as a View Preset – as described in Section B.4. D-6

E: Image Analysis The OTR 1001’s View window offers a wide choice of image analyses, described over the next few sections of this User Guide. Note: Users of the PQA option should however note that some displays – specifically, the Waveform display, the Vectorscope display and the CIE Chart – are not available when the OTR is operating in PQA Mode (as described in Section S). This section starts with a brief review of the steps needed to use these displays, then goes on to describe the Waveform View; the Vectorscope; the Gamut View and the Status displays – the four analyses that are provided as standard on the OTR 1001. Where these data analyses focus on displaying the results from a particular area of the image, the way in which this ‘Focus of Analysis’ is selected is described in Section E.2.

E.1 General Steps The following steps are used in working with the Views described in this section: Control Panel

Mouse & Keyboard

1. Display the required View in one of the tiles of the current View window. Move the focus to the chosen tile – or if the focus is already on this tile, clear any Button Bar that is shown by pressing OTHER or BACK – then press the appropriate Tile button The button to use is detailed under ‘Selection’ in the following descriptions. Note: Where more than one View is included in a particular category, you may need to press the Tile button more than once before the required View is displayed.

To do this: Either: Move the focus to the chosen tile then select the required View from the appropriate Category section of the View Tile Browser (as described in Section C.3). Or: Right-click on the required tile, select the Replace Tile option, then select the required View from the associated sub-menus. The View to select is detailed under ‘Selection’ in the following descriptions.

Note: Some types of display – specifically waveforms, the vectorscope, the CIE Chart and the Eye Diagram – make significant use of resources. However, this is only an issue if you attempt to display more than four of these at the same time or if you try to show more than one Eye Diagram. 2. Ensure that the relevant system parameters are set appropriately on the Video Config and Audio Config pages of the Config window (see Section T.2 and T.3). Details that may be important are listed under ‘Configuration Issues’ in the following descriptions. 3. Set the View’s ‘Properties’ to give you the display you require. The Properties control is described in Section C.3. The different properties of the display that can be set are detailed under ‘Display Properties’ in the following descriptions. 4. Determine the required information from the display that is shown. The descriptions of each View also include details of any particular measurements (or other determinations) that can be made from the View. Note: If a tile isn’t big enough to show the entire display, the tile will be shown with scroll bars. With a mouse, these scroll bars can be simply dragged to show the part of the display you are interested in. The scroll bars can also be moved by pushing the corresponding HORIZ or VERT knob, then twisting to make the required adjustment. (Push the knob a second time to cancel this action.)

You may also wish to limit the part of the image that is analysed, by defining the Region of Interest (see below).

E.2 Focus of Analysis While many of the results displayed by the OTR 1001 come from analysing entire frames of video, the system can be set such that displays such as the Waveform View and the Vectorscope just show the results from a particular line or band of lines of each frame, or from a particular ‘Region of Interest’ or to show just the data that applies at or around a particular point within the frame (indicated by a ‘crosshair’ cursor on the Picture display).

Figure E-1: Waveform View showing YCbCr components around point in frame marked by crosshair cursor on the Picture display. The Region of Interest and the position of the crosshair can both be seen on the Picture display and can be adjusted via that display. However, the choice of the area to work with and the position of the crosshair cursor typically need to be coordinated across more than one display, so the details are seen as properties of the video stream under test rather than of the Views through which the results are displayed. The relevant settings are therefore displayed – and can be adjusted – in the Inputs section of the View window’s Properties control. Line Mode The Line Mode control works with Line Mode controls for the Waveform, Vectorscope and CIE Chart displays. When set to Single, it switches all the above displays to analysing the line under the crosshair cursor (see below): the individual displays can subsequently be set to display ‘MultiLine’ results. The other options here define how much of the frame is analysed when this MultiLine option is taken, either All the lines of the frame, just the Active lines or a Custom band of lines (defined by Y start and Y range). E-2

Crosshair The Crosshair entry provides both controls for and information about the current focus within the video display (as indicated by the crosshair on the Picture display). The position of this crosshair determines such things as the line that is displayed when the waveform is set to ‘Single line’ and the pixel around which the DataView display is based. The X and Y controls allow you to position the crosshair anywhere within the frame, including the blanking areas, while the Field control switches directly between the two fields of an interlaced signal. The crosshair can also be re-positioned from the Picture display and from the Data View (where licensed) – as described in other sections of this guide. The crosshair position is normally measured in pixels from the top left-hand corner of the screen but when the VIEW_3D option is enabled (see Section I), it can optionally be expressed as a percentage of the screen width or in metres with the origin at the centre of the screen. Region of Interest (ROI) When enabled, the Region of Interest defines the part of the image that is analysed in the Waveform, Vectorscope and Histogram displays. The Region of Interest settings define: Whether analysis is required just of the marked area (Enable ROI ticked) or of the whole area (Enable ROI clear) The position of the top left-hand corner of the Region of Interest (Y defines the top line; X defines the leftmost pixel on that line) The Width and Height of the Region of Interest. The Region of Interest can also be sized and positioned directly on the Picture display, using the HORIZ and VERT knobs – as described in Section F.4. Note: Selecting a View Preset (see Section B.4) automatically clears any Region of Interest that was previously selected.

E.3 Waveform View (Not available in PQA Mode) The Waveform View offers high resolution displays of the video’s YCbCr / RGB components. Arbitrary combinations of colour components may be displayed simultaneously, optionally together with a composite waveform derived from the luma and chroma data within the original video stream (see below). Waveforms may optionally be overlaid with a graticule calibrated in ms along the (horizontal) timing axis and giving either digital values, percentage IRE or millivolts along the vertical voltage axis. The labels shown below are also optional. For RGB and YUV, two separate waveform calibrations are offered: SMPTE range (decimal 64 – 940/960) or Full Range 0 – 1023 (Full Range is always used when working with XYZ), Waveforms can be shown either for a single line (the line currently selected by the crosshair cursor) or for all the lines in the current frame/in the current Region of Interest where this is enabled (see above). If required, the waveform can be shown offset from either axis of the graticule or the whole pattern shifted up or down, left or right by applying the appropriate offset – see ‘Lock Waveform Graticule’ below. Waveforms may further be adjusted for gamma and other corrections that may have been applied to the video source. Gamma may be either applied or removed as required, while other linear, log or custom adjustments applied to RGB or XYZ waveforms can be handled through the application of the appropriate look-up table (LUT). The Reference White Level used in converting between RGB and XYZ may also be set to the required value. Note: Custom lookup tables should be in CSV (comma separated variable) format. LUTs are included for Sony SR and Thomson Viper cameras, which can be modified to create complete custom LUTs. The supplied LUTs are located in c: Program Files\OmniTek\DataLab\LUTs Where the VIEW_3D option is installed, the Waveform View can also be used to compare luma and chroma levels between left-eye and right-eye Stereo 3D video images (see Section I.8).

Figure E-4: Example waveform display. Control is offered over several aspects of the waveform display, including: Which colour components are displayed, the colour(s) they are displayed in and how they are arranged (in parade form; stacked or overlaid). The line/lines of the video that are analysed together (selected through a combination of the position of the crosshair cursor, the line mode and the sweep mode). The horizontal magnification and vertical gain that are applied. The OTR 1001 also offers the option of filtering/ interpolating the waveform. E-4

OmniTek OTR 1001 User Guide, v3.0

To allow the waveform to be measured, pairs of horizontal (time) and vertical (amplitude) cursors can be displayed, together with a read-out of their positions and the spacing between the cursors. To make it easier to compare one waveform display against another and/or against particular requirements, you can also define one or more additional time and amplitude markers. These ‘Shared Waveform Markers’ work with all waveform displays to provide user-defined reference points for comparisons between different displays. In the main, the display options are set as part of the tile’s properties i.e. set within the Properties control and, in some cases, also controlled from the Button Bar (Control Panel: press GENERAL; Mouse/Keyboard: click on tile to display). The exceptions are the details of which line(s) are analysed which are set as properties of the selected input because they potentially apply across a number of displays. (See the section above on the ’Focus of Analysis’.) Internal signal processing is normally performed to 10-bit precision, but where the VIEW_XR_DCI option is installed, the precision is increased to 12-bit. This option also adds support for the XYZ colour space.

Selection The Waveform View is a member of the WFM category. Control Panel

Mouse & Keyboard

To display the Waveform View: Press the WFM tile button.

Select Waveform from the WFM section of the View Tile Browser.

(For more detailed instructions, see Section E.1.) Note: No more than four waveforms, vectorscopes or CIE Charts can be displayed at the same time.

Configuration Issues The following Configuration settings affect how the waveform is displayed. Note: Further settings are required where 3D images are analysed: these are described in Section I.8. Input Settings Certain aspects of how the input is interpreted are configurable as follows. The required settings are all made on the Video Config page of the Config window (described in Section T.2). 1. Two waveform calibrations are offered for RGB and YUV: SMPTE (64 – 940/960) or Full Range (0 – 1023). (Full Range is always used for XYZ.) The required Range is selected within the RGB Input section of the Video Config page. 2. The RGB Input and XYZ Input sections also include a LUT setting that controls the application of either a standard or a custom look-up table to the input data. 3. These sections also include a Remove Gamma setting for handling gamma-encoded input data. 4. The XYZ Input section also includes a Reference White Level setting for use in converting between RGB and XYZ. The standard value for the white level is 48cd/m2 Range Errors Parts of the waveforms that fall outside the pre-set legal range are displayed in a different colour. The values at which any colour component switches between being ‘legal’ and being ‘illegal’ is part of the system configuration. The OTR 1001 is delivered with these levels set in accordance with standard practice within the industry. The current settings can be viewed and adjusted as required on the Video Config page.

Lock Waveform Graticule A lock is associated with the graticule that overlays the waveform. Where this lock is set, applying horizontal and vertical offsets (as described under ‘Display Properties’ below) moves the waveform but does not move the graticule. When the lock is not set, the whole pattern (waveform + graticule) can be shifted left or right, up or down the screen by applying horizontal and vertical offsets. Whether the graticule is locked is set on the System page of the Config window. Amplitude Measurement Units The units in which the signal amplitude axis is measured is set by the Amplitude Measurement Units setting on the System page of the Config window. Composite Matrix Different matrices may be applied in producing the composite waveform display. The OTR can either be set to select the appropriate matrix automatically, based on the input video standard or it can be set to select a particular composite matrix. The selection is made through the Composite Matrix Type option offered on the Video Config page of the Config window.

Display Properties Other aspects of the Waveform View are determined by the tile’s properties, a complete read-out of which is given in the Properties control (Control Panel: press PROPS to display). Shortcuts to several settings are provided through the Button Bar (Control Panel: press GENERAL or OTHER; Mouse/Keyboard: click on tile to display). Scaling and Offset H Mag and V Gain define the horizontal and vertical scaling applied to the waveform. The options in the Properties control are associated with a range of values (H Mag: x1, x2, x5, x10, ROI; V Gain: x1, x2, x5, x10). Selecting the H Mag/V Gain option offered in the Button Bar switches between 1x and the last of the other scalings to have been selected. H Offset and V Offset define the offset of the waveform displayed from the time and voltage axes. These offsets may also be adjusted by turning the HORIZ and VERT knobs (respectively), while pushing either knob returns the corresponding control to its default position. Note: The HORIZ and VERT knobs cannot be used to adjust these offsets when cursors are displayed (see below) because then the role of these knobs is to move the cursors. Note also that if the waveform graticule is unlocked (see Configuration Issues above), adjusting the offset simply shifts the whole pattern up or down, left or right. E-6

Mode of Operation The Colour Mode control selects between YRGB, YCbCr, Bowtie, Composite etc. waveforms, while the following tick selections control the components that are actually displayed. The Button Bar option cycles through the available settings. The Line Mode control selects between displaying the waveform of a single line (picked out by the crosshair cursor) or multiple lines. The Button Bar option switches between these two settings. When Labels are shown (see Show Labels below), the Line Mode that is currently selected is shown in the top right-hand corner of the display as either Line (single line) or Multi (multiline). Where Single line is selected, the line being analysed is shown in the bottom left-hand corner of the display. (For details of the lines selected, see Section E.2 ‘Focus of Analysis’.) The Sweep control selects between displaying traces from a single sweep and traces separated by one line, one field or one frame. The Button Bar option cycles through the available settings. The Filter control selects how the incoming data is sampled. The choice offered is between a Flat filter, a Low Pass filter or No Interpolation. The Button Bar option cycles round these three options. When Labels are shown (see Show Labels below), the type of filtering that is being applied is shown in the bottom right-hand corner of the display. Interpolation is usually enabled but users should be aware that it can occasionally produce out of range results. Where these occur, you may prefer to turn the interpolator off. The TRS Passthrough tick selection enables the inclusion of the TRS in the display. Cursors The OTR offers cursor-pairs through which time differences and amplitude differences may be determined, together with optional user-defined time and amplitude cursors (see ‘Shared Waveform Markers’ below). The Time, Amplitude and Shared markers options provide individual control over the display of the different sets of cursors while Show Cursors provides overall control over the display of the cursors over the waveform display. Show Cursors is also turned On and Off by the Cursors option on the Button Bar. The individual cursors of the Time and Amplitude cursor pairs may be moved using the HORIZ and VERT knobs. The cursor moved is the one currently shown in yellow. Pushing the knob switches over control to the other cursor. The Shared markers may be positioned either by setting values in the Shared Waveform Marker section of the View window Properties control or by Ctrl-clicking and dragging with a mouse. The X1, X2, Y1 and Y2 selections in this part of the Properties display control the two pairs of cursors, one pair providing difference measurements in the horizontal (time) direction and the other pair providing measurement in the vertical (amplitude) direction. Display Mode The Display Mode control allows a choice between Overlay; Parade; and Stacked presentation of the component waveforms. The Button Bar option cycles through these arrangements. Dither Mode This option offers a choice of Dither mode between 8bit, 10bit and 12bit (where supported). Visualisation The Gain control sets the intensity of the displayed waveform (as a percentage of the received signal level). The Persistence setting sets the rate at which the displayed data decays. Larger values have the result of smoothing out time variations. OmniTek OTR 1001 User Guide, v3.0

E-7

The Gamma setting applies gamma encoding to the waveform. A setting of 100 corresponds to a gamma value of 1. The CRT Emulation option applies a special filter to the waveform data to emulate the look that is typical of analog CRT-based waveform monitors. The Show Graticule option controls the display of the underlying grid. The Show Labels option controls the display of labels and other additional information. Colour The Colour setting selects the colour used for the waveform trace, out of Cyan, Green, White, ‘Temperature Ramp’ or ‘Match Component’ (which makes each trace the appropriate colour for the component represented). (For information about the 3D View option, see Section I.8.) Button Bar

Composite Waveforms One of the Colour Mode options offered by the OTR is ‘Composite’. The composite waveform takes the form of a band of varying width around a central line that follows the Y (luma) component of video data. The width of the band at any point of the waveform is determined by the chroma components of the waveform, the magnitude and phase of which determine an overall magnitude (M) for the colour component of the signal. The outer limits of the composite waveform are given by Y + M and Y – M. The area between the Y + M and Y – M curves is filled in with solid colour as there is no useful information to be obtained from this area.

Figure E-6: Composite Waveform display Different Composite matrices need to be applied depending on the input video standard. As part of the Video Configuration (see Section T.2), the OTR can either be set to select this matrix automatically or to select a particular matrix. The matrix that is currently being applied is shown in the heading to the composite waveform display. Y, U and V waveforms can optionally be displayed alongside the composite waveform in the same tile. To see R, G and B alongside a composite waveform, set up a second ‘Waveform’ tile to show RGB. E-8

Waveform Measurement To enable the waveforms to be measured, pairs of voltage and time cursors can optionally be overlaid on the Waveform display, so the first step is to display these cursors. These cursors may be moved using the HORIZ and VERT knobs or by dragging with a mouse. The cursor that is moved by the knobs is the one currently shown in yellow. Pushing the knob switches control over to the other cursor. A read-out showing the current positions of the cursors and their separation is displayed in the top right-hand corner of the screen. Control Panel

Mouse & Keyboard

To display the cursors: To select which cursors are displayed, tick the required cursors in the Properties control. Toggle between displaying and hiding these cursors either by ticking and clearing the Show Cursors option in the Properties control or by selecting the Cursors option from the Button Bar (highlighted when the cursors are displayed).

Shared Waveform Markers To aid comparisons across multiple waveforms, the OTR allows you to define one or more additional ‘Shared Waveform Markers’ that occupy the same custom positions across all waveform displays. The Waveform Markers are set up either through the Shared Waveform Marker section of the View window Properties Control or, where a mouse and keyboard are fitted, through the Rightclick menu. Additional Time markers and Amplitude markers can be set up, positioned and removed both using this section of the Properties Control and from the Right-click menu. The display of the markers on any particular Waveform tile is controlled separately through the Cursors section of the Waveform Properties. Here their display is controlled both through a Shared markers option that needs to be ticked, and the same overall Show Cursors option used to toggle the display of the pairs of measurement cursors.

E.4 Vectorscope (Not available in PQA Mode) The Vectorscope displays a vector representation of the incoming waveform.

Figure E-8: Example Vectorscope display. The Vectorscope can be displayed either from SDI data or from the equivalent Composite signal and may be shown on either 75% or 100% graticules. If required, a ‘Luma mask’ can be applied that limits the display to luma values between defined minimum and maximum values. The graticules are automatically adjusted for the appropriate 601, 709 or composite colour matrix. The vectorscope can also be displayed at a range of different magnifications – including your own choice (up to 20x), selected either by turning the HORIZ knob on the Control Panel or by clicking and dragging. (Note: Pressing HORIZ returns the scaling to 1x.) The graticule can either scale with the vectorscope display or keep its 1x size by ticking the Fixed Graticule option in the Properties control. Where the VIEW_3D option is installed, the Vectorscope can also be used to compare luma and chroma levels between left-eye and right-eye Stereo 3D video images. This is described in Section I.8. The display is constructed from an analysis of the active video, however when the Enable ROI option is ticked for the selected input in the Properties control, the analysis is limited to the current Region of Interest (see Section E.2).

Error Mask The OTR 1001 allows you to specify a number of lines from the top and bottom of the display and a number of pixels from the left and right edge that can be omitted from the checking process. This is referred to as an Error Mask and it is defined on the Video Config page of the Config window. Its purpose is to avoid producing misleading results as a result of including video data that has been corrupted by the sync. Composite Matrix Different matrices may be applied in producing the composite version of the Vectorscope display. The OTR can either be set to select the appropriate matrix automatically, based on the input video standard or it can be set to select a particular composite matrix. The selection is made through the Composite Matrix Type option offered on the Video Config page of the Config window.

(For details of the lines selected, see Section E.2 ‘Focus of Analysis’.) Where Single line is selected, the line being analysed is shown in the bottom left-hand corner of the display. The Mag option in the Properties control offers the choice of 1x, 2x, 5x or whatever customised (xx.xx) zoom was last selected, while the Mag option on the Button Bar switches between 1x and the last of the other scalings to have been selected. (Customised zooms are selected either by using the HORIZ knob on the Control Panel or by clicking and dragging. Note: Pressing HORIZ returns the scaling to 1x.) The Colour Mode control selects between displays based on the SDI input or on the Composite version (see Waveform View above). The Button Bar option switches between these options. Note: The OTR automatically switches the graticule to match the selected Colour Mode. The Dither Mode option offers a choice of Dither mode between 8bit, 10bit and 12bit (where supported). Luma Mask When Luma Mask is selected, the display becomes limited to those pixels whose luma value lies between the associated Minimum and Maximum settings. The Button Bar option switches between the two displays. Visualisation The Gain control sets the intensity of the displayed waveform (as a percentage of the received signal level). The Persistence setting sets the rate at which the displayed data decays. Larger values have the result of smoothing out time variations. The Gamma setting applies gamma encoding to the waveform.

E.5 Gamut View The Gamut View chiefly comprises a set of bar graphs showing the range of values for the different possible colour components (YCbCr, RGB, Composite and XYZ where supported) in the video currently being analysed.

Figure E-10: Example Gamut View display. The individual graphs show the ranges encompassed by the current frame. Where the values go outside the configured legal values, the values in excess are shown in red. Displayed at the bottom of the Gamut display are details of the percentage of pixels in the current frame for which the value goes outside the specified ranges, together with details of the peak value of this percentage over the session since the last time the display was reset (e.g. using the Reset button on the Button Bar). Note: These values are also reset when the overall status is reset (see Section E.6).

Separate settings are made for each component of the RGB, YCbCr and XYZ colour spaces (where supported). The OTR 1001 is delivered with these levels set in accordance with standard practice within the industry. The current settings can be viewed and adjusted as required on the Video Config page of the Config window. Error Mask The OTR 1001 allows you to specify a number of lines from top and bottom of the display and a number of pixels from the left and right edge that can be omitted from the checking process.

E.6 Status The OTR also provides real-time status information about the video signal under test and, in particular, about errors displayed in that stream. This information is displayed in two forms – as a hierarchical tree giving an overall listing of the current status (the ‘Status Overview’) and as a set of ‘Status Summaries’ covering different aspects of the system e.g. the video content, the audio levels etc. Both forms of the display are provided within the same Status display, called up either by pressing the STATUS button or by selecting Status from the STATUS section of the View Tile Browser. The different displays are then shown by selecting different options from the associated Button Bar (displayed e.g. by pressing the OTHER button or clicking on the Status View with a mouse). Button Bar

The Status Overview

Figure E-12: Status Overview The information shown by the Status Overview depends on the item being reported but in most cases reports the current value of the parameter (which may or may not be in error), a cumulative total of errors since the display was last reset and the average number of errors per frame. Detailed information about the data displayed is given in Section 0. The information shown is displayed in a collapsible hierarchy similar to that used in the Properties control. As in the Properties control, a [+] next to any ‘heading’ indicates a section, the details of which are currently hidden, whereas a [-] next to a heading indicates that the associated part of the hierarchy is already displayed. However, unlike the Properties control, this hierarchical structure is navigated from the Control Panel using the VERT knob, rather than the GENERAL knob – while the HORIZ knob can be used to scroll the display from left to right when a scroll bar is shown at the bottom of the E-16

OmniTek OTR 1001 User Guide, v3.0

display. It is also the HORIZ and VERT knobs that are pushed on the [+] and [-] markers to open and close sections of the hierarchy. (Pushing either the GENERAL knob or the OTHER button displays the Button Bar.) Through opening some sections of the hierarchy and closing up others, you can readily tailor the display to show just the information you are interested in. As shown in the example display, the ‘values’ associated with particular status items are shown in colour make it immediately clear where the value currently being reported is incorrect in some way because it is shown in red. In addition, the section headings (together with the main ‘Video’ heading) may be marked with a cross in a red circle to indicate where either an error or a critical error has been detected among the items of that section. This provides a simple and effective way of, firstly, alerting the user to the fact that an error has occurred and, secondly, guiding the user to the relevant part of the status display. Note: Where the Status display includes line and field details, selecting the symbol next to this information automatically adjusts the position of the crosshair cursor and hence the focus of displays such as the Data View to the specified position within the image to allow closer investigation. You should also note that the aspects of the video that are checked depend both on the video format and on which software options are installed.

Status Summary The Status Summary displays comprise a set of pages, each showing status information about a different area of the video being analysed. These displays are grouped into a number of categories, each associated with a separate button on the Button Bar.

The displays are called up by selecting the appropriate button on the Button Bar. A single press selects the most-recently selected display within the selected category; subsequent selections cycle through the other displays of that category. Alternatively, pressing and holding the button calls up a menu of the displays within that category, from which to select the one you want. The information shown depends on the item being reported but in most cases reports the current value of the parameter (which may or may not be in error), a cumulative total of errors since the display was last reset and the average number of errors per frame. Detailed information about the data displayed is given in Section 0. As in the Status Overview, the ‘values’ associated with particular status items are colour-coded make it immediately clear where the value currently being reported is incorrect in some way because it is shown in red. Note: The aspects of the video that are checked depend both on the video format and on which software options are installed. In particular, the PHY display is omitted if the EYE option is not installed or if there isn’t any physical data included in the input.

Configuration Issues The following Configuration settings affect the data displayed on the Status View: Error Ranges, Persistence and Severity The level at which any aspect of the video becomes in error, the length of time that this condition has to persist for an error to be reported and the severity of that error (Error/Warning/OK) is part of the system configuration. The OTR 1001 is delivered with these levels set in accordance with standard practice within the industry. The current settings can be viewed and adjusted as required on the Video Config and Audio Config pages of the Config window. Further details are given where these pages of the Config window are described (Section T). Error Mask The OTR 1001 allows you to specify a number of lines from top and bottom of the display and a number of pixels from the left and right edge that can be omitted from the checking process. This is referred to as an Error Mask and it is defined on the Video Config page of the Config window. Its purpose is to avoid producing misleading results as a result of including video data that has been corrupted by the sync.

Display Properties The widths of the different columns of the display may be adjusted either by dragging wit h a mouse (where fitted) or through the Properties control (Control Panel: press PROPS to display).

Column Widths The information on the Overview page is displayed in four columns. The first column is used to display the names of the parameters that are being monitored (in the appropriate hierarchy). The other three are used to display status/current value/average value/error count etc. as appropriate. The four thumbwheels in the Properties control allow the widths of the four columns to be individually adjusted (either scroll the value up/down or type a new value using the numeric keypad). The column widths can also be adjusted by dragging with a mouse. Select Reset: Go to reset the column widths to their default values.

Resetting the display The second number given for some of parameters displayed in the Status View represent the number of errors that have been detected since the error counter was last reset. Control Panel

E.7 Video Information Displayed This section provides background information on the video parameters that appear in the various status displays. While the majority of these parameters are included in at least one of the Status Summary displays, the full range can be seen in the Status Overview. The category of the Status Summary on which any parameter is shown in brackets. Note: The levels at which an error is deemed to have occurred and the length of time the error condition has to persist before an error is reported are set on the Video Config page of the Config window. Note also that entries in the Status Overview that are marked with an arrow provide a shortcut that moves the crosshair cursor and related displays (see Section E.2) to the feature that is being referred to in the status. Format (Video and AUX) The Format entry gives the video standard to which the incoming video is locked, together (where applicable) with the Composite Matrix type that is applied. Format (Auto) indicates that the video standard has been automatically determined by the OTR e.g. from SMPTE 352 packets within the video stream. Format (Manual) indicates that the video standard being used has been selected as part of the Video Configuration (see Section T.2). The SMPTE 352 (Luma) and SMPTE 352 (Chroma) entries interpret SMPTE 352 data (where detected). Where an analog reference signal is being fed into the OTR via the Reference Loop (see Section A.2), the Analog Reference entry shows the video standard of this reference. Picture Content (Video) The Motion entry reports whether the image has been determined to be Active or Frozen, together with the number of frames for which the motion has been frozen since the last reset. The Luminance entry reports whether the image has been determined to be Active or Black, together with the number of frames for which the picture has been entirely black since the last reset. The Chrominance entry reports whether the image has been determined to be Active or Monochrome, together with the number of frames for which the picture has been monochrome since the last reset. The Average Picture Level gives the average signal level with respect to blanking over the active part of the frame. The Stuck Bits entries give indicate those bits of the Y, U and V values that are consistently either High (H) or Low (L) over the whole of the active frame. These entries can be useful in identifying issues with how the video is being transmitted. For example, if 10 bits are indicated but the last two are shown to be L, it suggests that you are actually working with 8-bit data.

Blanking Width This section gives the Width of the horizontal blanking in both pixels and μs, together with details of any Left/Right displacement (up to a maximum of 255pixels). Picture Size This section gives the Height and the Width of the active area in lines, together with details of the displacement of this area Top+Bottom / Left+Right from the edges of the standard filed/frame area e.g. as a result of using a letterbox format to provide a widescreen image. Gamut Errors (Video) The Gamut Range section of the Status display is divided into YCbCr, RGB and Composite data. In the Status Overview, it is further divided into two parts, the first providing details about the current frame and the second providing Session data (i.e. min, max etc. data recorded since the display was last reset). The YCbCr Range section gives the number of pixels for which the YCbCr data is in error as a percentage of the current frame, the total number of frames for which the error level recorded in the Video Config was exceeded since the last reset and a count of these error frames per second (EFPS). It also shows the maximum and minimum Y, Cb and Cr values experienced. (The minimum and maximum thresholds are set on the Video Config page of the Config window.) The RGB Range section gives the number of pixels for which the YCbCr data would be invalid if converted to RGB space as a percentage of the current frame, the total number of frames for which the error level recorded in the Video Config was exceeded since the last reset and a count of these error frames per second (EFPS). It also shows the maximum and minimum RGB values experienced. (The minimum and maximum thresholds are set on the Video Config page of the Config window.). The Composite Range section similarly gives the number of pixels for which the composite value determined from the YCbCr data would be invalid as a percentage of the current frame, the total number of frames for which the error level recorded in the Video Config was exceeded since the last reset and a count of these error frames per second (EFPS). It also shows the maximum and minimum values experienced. (The minimum and maximum thresholds are set on the Video Config page of the Config window.). Physical Errors (Video) The entries in this section show parameters in error and give error counts for a range of standard features of the video data stream. For instance, the ANC entry counts invalid ANC checksums. The Frames in Error entry records the number of frames where any of the listed physical errors have occurred. The Line entry counts TRS packets where the line number specified does not agree with the line number calculated internally. Note: This entry is only applicable to HD and 3G video: Line numbers are not included in TRS packets in SD. To check CRC/EDH values, the OTR calculates a new CRC value (EDH in SD) from the incoming data, and compares this value with the CRC (EDH) value embedded in the data. If there is a difference, this is flagged as an error. The CRC/EDH values that have been calculated for the active area and for each full field/frame are also displayed.

The constants and minimum and maximum distances used in the calculations are recorded on the System page of the Config window; the levels at which an error is triggered are set on the Video Config page. For further information, see Sections I and T. Quality Analysis (where included) The entries in this section report: The current value of the various Picture Quality measurements (PQA option: detailed in Section S) The current value of the various Audio Quality measurements (PQA option: detailed in Section S) The audio and video delays determined by the ‘In-Service’ A/V Delay measurement facility (AV_ISD option; detailed in Section N) Eye/Jitter Data – where supported (PHY) The entries in this section report: The amount of Jitter (expressed in UI) for different filter settings. The estimated cable length (based on the cable type selected on the System page of the Config window (see Section T.4) The Eye amplitude (expressed in mV) The Eye rise/fall times (expressed in ps) The Eye Rise/Fall ‘Delta’ i.e. the difference between measured rise and fall times (expressed in ps) The Eye Rise/Fall Overshoot (expressed as a percentage of the Eye amplitude). Whether the Jitter measurement has successfully locked Note: The various Eye measurements (amplitude, rise/fall times etc.) are made using the Auto Measure feature and so are only valid when one of the tiles is showing an Eye display for the selected input and Auto Measure is enabled. Note also that Auto Measure can fail if the Eye diagram is ‘dirty’: the Eye status will then be cleared while the overlay in the window will show “---” for the rise and fall times. E-22

Timecode Data (AUX) The OTR checks the data stream for timecode data. Where a timecode is present, it is displayed alongside the corresponding timecode type, together with details of the location at which the data was found. The OTR also monitors each timecode to ensure that it increments correctly from frame to frame, and a count is made of this discontinuity each time a timecode value is either duplicated in adjacent frames, or is discontinuous from frame to frame. Note: ATC is a timecode packet which can be loaded with either a LTC, VITC #1, or VITC #2 timecode. Note also that the timecodes are completely independent so you may see different values where one part of the display uses VITC #1 codes while another uses VITC #2. Captions (AUX) This section reports on the presence of CEA-608, CEA-708 and Line 21 closed captions and/or PAL or OP-47 teletext in the data stream. Where any of these message types is present, details are given of the location at which the message has been found. For CEA-708 captions, the OTR also reports on the validity of the caption distribution packet and gives the service names of up to 6 services. For OP-47, it also reports on the validity of the subtitle distribution packet and the VBI packets it includes. Wide Screen Signalling (AUX) The entries in this section report data determined from any ETS 300 294 or ARD Spec WSS codes detected in the video input. Video Index (AUX) The entries in this section report data determined from ARD Spec or RP186 Video Index codes detected in the video input. Active Format Description (AUX) Here the OTR 1001 reports the presence and validity of any AFD 2016 Active Format Description that is detected in the video input. Where such a description is detected, the line numbers and pixel numbers specified for the start and finish of the active frame area are displayed on the screen.

F : Picture Display F.1 Basic Picture Display The main role of the Picture display is to offer a high-resolution real-time representation of the video currently being analyzed. Various alternative picture displays may be shown where the OTR is being used to analyze Stereo 3D video (see Section I) or to assess Picture Quality (see Section S).

Figure F-1: Example Picture Display. The video can either be shown full raster, limited to just the active picture or shown in a “pulsecross” configuration that allows the contents of the H & V blanking areas to be viewed. Other facilities include “burn-in” windows for overlays such as timecodes, a crosshair marking the current point of interest for analysis (and an exploded view of the image at that point), selection of a ‘Region of Interest’ and the option to set pixels that are out of gamut to flash. Where the VIEW_3D option is installed, the Picture display also includes some ‘3D’ options. These are described in Section I. The aspect ratio used for the display can either be set manually or determined directly from the image (assuming square pixels) or taken from Video Index, Wide Screen Signalling or Active Format Description data embedded in the video. The video images can be shown either on the standard analyzer display or on a separate monitor. The technology used is capable of supporting a 1:1-size full-motion display of input images at up to 1080p60 resolution including all the blanking and ANC data areas. Note: If you find pictures are being slow to load, it is worth checking if 3D Monitoring is enabled on the System page of the Config window and disabling this if it is not being used.

Configuration Issues The following Configuration settings affect the Picture display: Pixel Flashing Alongside the settings specifying the acceptable RGB range on the Video Config page of the Config window is the option to ‘Show on UI Picture’. A similar option appears in the section of this page that deals with the acceptable YCbCr range. Both options are tick box selections. Where Show on UI Picture is ticked, any pixels with colour components that lie outside the required range are automatically keyed out and replaced by a flashing black and white signal on the Picture display. Aspect Ratio Also on the Video Config page of the Config window is a group of options concerned with the Picture Aspect Ratio. The Type option selects the source for the aspect ratio used in displaying the Picture view, from a choice of ‘None’, ‘Manual’ and various WSS, Video Index and Active Format Descriptor formats. The ‘None’ option causes the aspect ratio to be set by the number of lines and the number of pixels per line in the Active frame, while the WSS, Video Index and AFD options tell the OTR 1001 to take the aspect ratio from the associated embedded data. Alternatively, a specific aspect ratio can be set by selecting the Manual option and then setting the required X and Y components of this aspect ratio as the Manual X Aspect Ratio and Manual Y Aspect Ratio values. Note: Additional settings are required where Stereo 3D video is being processed. For information, see Section I.

Display Properties Other aspects of the Picture display are determined by the tile’s properties, a complete read-out of which is given in the Properties control (displayed by pressing the PROPS button). Shortcuts to the most-commonly required settings are provided through the Button Bar. (Control Panel: press GENERAL or OTHER; Mouse/Keyboard: click on the tile to display.). Note: The Properties control and the Button Bar shown in PQA Mode are slightly different. For details, see Section S.3.

Size The Size option offers a choice of having the picture size automatically Stretched (scaled) to fit the tile or being displayed at 1:1 size (half width, half height), regardless of the size of the tile in which it is displayed (Unity). The Button Bar Size option switches between these two settings. Mode The Mode option offers a choice of picture display mode: Active Picture: Shows the active image area. Pulse Cross: The Pulse Cross mode delays the video by half a frame both horizontally and vertically, to emulate the HV delay mode of CRTs. This can give a clearer view of the data adjacent to blanking. Full Raster: Shows both the active image area and the blanking area. The display also covers both fields of interlaced video. Where the VIEW_3D option is installed, the range of modes also includes a 3D mode. For information on this, see Section I. The Button Bar Mode option cycles through these display modes. Picture Source (where included) This section is included when the OTR is operating in PQA Mode and allows you to select from the various picture display options offered in that mode. For further information, see Section S.3. Timecode The Timecode options in the Properties control enable the display of timecode data embedded in the video and define the text style and the position for their display. The Timecode button on the Button Bar switches this display on and off. The display of timecodes is described further in Section F.2. Closed Captions The Closed Captions options in the Properties control enable the display of captions embedded in the video. The Captions button on the Button Bar switches this display on and off. The display of captions is described further in Section F.2. Enable ROI/Modify ROI These options enable the definition of a Region of Interest on the Picture View as described in Section F.4. When enabled, Waveform, Vectorscope and Histogram analysis is only applied to the selected Region of Interest. Zoom The Zoom View option adds a sub-window containing a 15x or 31x image of the pixels around the current position of the crosshair cursor (see Section F.5). Crosshair The Crosshair options in the Properties control enable the display of the crosshair cursor, while the Show Crosshair option on the Button Bar switches this display on and off (see Section F.2).

F.2 Picture Overlays Where the video being analysed includes timecodes, closed captions or teletext subtitles, these can be overlaid on the Picture display. Another possible overlay is the crosshair cursor that marks the current focus for analyses such as the Waveform View and the Data View.

Crosshair The crosshair cursor that marks the focus for displays such as the Waveform View and the Data View can be both shown and moved on the Picture display. The display of this crosshair is principally controlled by the Crosshair section of the Picture properties, where the Crosshair options control whether the crosshair is displayed or hidden and whether it is shown as a short cross or full height. The crosshair is also turned on and off by the Show Crosshair option included in the Picture View’s Button Bar. The crosshair is also affected by settings within the Inputs section of the View window’s Properties control. These include settings for the x,y coordinates for the crosshair’s current position. The Properties control also includes a Show option that controls whether the crosshair is displayed or hidden.

Closed Captions & Teletext Subtitles The video under test may include closed captions or teletext subtitles.

Figure F-6: Picture View with Captions The OTR is able to automatically detect and decode ‘Line 21’, CEA-608 and CEA-708 captions (the latter from up to six services provided within the video stream), and overlay the decoded text on the Picture display. The only additional information that is required is the type of caption that is to be displayed. The OTR can also display PAL and OP-47 teletext subtitles in very much the same way as closed captions but, in this case, the page on which the subtitles are to be found also needs to be specified. The caption is displayed at the position and using the style specified in the caption code. Only one type of caption can be displayed on any Picture tile at a time but if the video under test includes captions in different formats e.g. both CEA-608 and CEA-708 closed captions, these can be viewed by setting up multiple Picture tiles, each displaying a different type of caption. There is also the option of recording captions in an XML log file – see Section J.4. OmniTek OTR 1001 User Guide, v3.0

F.3 Safe Action/Safe Title Cages The OTR allows ‘cages’ representing safe-action and safe-title areas to be marked out on the Picture View (as described here) and included on the SDI output when the OTR is used in PassThrough mode (see Section P.4). It is also possible to save the cages you define as a ‘Cage Preset’, for re-use on a subsequent occasion.

Figure F-8: Picture View showing cages. For both cages, you are offered a choice of opting for a ‘Fixed’ cage or an ‘Adjustable’ one. The ‘Fixed’ cage option offers a range of pre-defined cages, always centrally positioned, the area of which is given as a percentage of the display. The ‘Adjustable’ cage option allows you to specify the dimensions you require. Opting for an adjustable safe title cage also allows you to choose where this cage is positioned. The cages are defined as properties of the Input and can be enabled either individually or together as required. Their display over the Picture (and their inclusion on the SDI Output) are controlled by separate ‘Show Cage’ options. The default is for both cages to be marked out by a solid white line but, to allow them to be distinguished when shown together, the safe title cage can optionally be marked out using a dashed line (as illustrated above).

G : Data View Adding the VIEW_DATA option adds the Data View displays, which show pixel data from the image that is currently being processed by the built-in analyser.

Figure G-1: Example ‘Standard’ Data View display.

G.1 Overview of Display The Data View is offered in two forms a Standard view which simply displays the pixel values, and an Extended view in which this data is interpreted. In particular, the Extended view offers interpretation of ANC packets transmitted within the blanking where it has descriptors for these. (Some XML-format descriptor files are supplied with the VIEW_DATA option. Users can also set up additional descriptor files – for example, for decoding custom ANC packets. This is described in Appendix I.) In both the Standard view and the Extended view, data is shown for a specified sample (pixel pair), together with samples earlier and later in the same line. The focus for the display is the current position of the crosshair cursor (as shown for example on the Picture display). Moving the crosshair cursor, for example on the Picture display, changes the focus of the Data View to a different pixel pair. Equally, moving the focus within the Data View moves the crosshair cursor. The display is scrollable, so you can check video data over a large portion of a video line without moving the focus. You can also check data within the blanking area. The same general steps are involved in working with this display as are used with other Views (see Section E.1). Note: Especially in Extended View, the information shown can often extend beyond the righthand edge of the normal display. To see information displayed beyond the edge of the tile, press the HORIZ button then twist to scroll the display from left to right. Press HORIZ again to return to normal operation.

Extended Views At any one time extended analysis may be given on up to four separate channels, corresponding to the components of a maximum of two data streams. The number and type of channels for which extra interpretation is given depends on the type of video that is being analysed. The Properties control offers a set of tick boxes through which to select the required extra information, however it is generally much easier to use the Buttons 5 – 8 of the Button Bar to select the required information as these are automatically labelled appropriately for the type of video that is being analysed. Format The Format setting principally selects between displaying the data in hexadecimal, decimal or binary. It further offers the option of interpreting 10bit data as 8 bits + 2 bits (and expressing the result either in hex or in decimal). This has the advantage of making standard groupings such as those associated with SAV and EAV easier to pick out. Font Size The Font Size option allows control over the size of text used in the DataView. The options are: Auto; Small; Medium; or Large. Auto leaves the selection of the text size to the OTR 1001 software, which then switches the text size that used between Multi View and Full View versions of the display. The other three options cause the chosen text size to be used for both Multi View and Full View versions of the display.

Setting the focus for the display As stated above, the focus for the pixel data displayed by the Data View is the current position of the crosshair cursor associated with the selected input stream. The position of this cursor may be set in a number of ways. Control Panel

G.2 Standard View When the ‘Standard’ version of the Data View is shown, it simply displays the pixel values.

Figure G-3: Standard version of the Data View.

Overview of Display Features The data is displayed as a number of columns. The first two columns indicate where the location of sampled pixel in the image (the ‘Sample’ number corresponds to the position along the line at which the data is being read). The other columns report the Y, Cb and Cr values associated with the selected pixel. The background against which the data is displayed is colour coded as follows: Green

indicates that the pixel is within active video

Blue

indicates that the pixel is within a TRS packet

Purple

indicates that the pixel is within an ANC packet

Light grey

indicates that the pixel is within horizontal blanking

Black

indicates that the pixel is within vertical blanking for field 1

Dark grey

indicates that the pixel is within vertical blanking for field 2

Red

indicates a data range error (i.e. video data outside the configured desired range, as set on the Video Configuration page of the Config window).

G.3 Extended View Where an Extended View is selected, the standard pixel value display is enhanced through the addition of pixel colour data and interpretations of identifiable structures such as ANC packets in the video signal.

Figure G-4: Extended View version of the Data View.

Overview of Display Features The way the columns are arranged and the additional information that can be displayed depends on the type of video signal that is being analysed. For instance, combined Y/C information is displayed for SD signals, but separate Y-type and C-type information is displayed for HD signals. Within the active video, both a value and a set of pixel data are shown for each pixel. In duallink input formats, the RGB and XYZ colour space data is assembled into full pixel values. EAV and SAV markers are both named and interpreted in terms of the FVH etc. information they contain. The interpretation given of ANC packets within the blanking area depends on the associated descriptor file (where supplied) but will typically show at least an identifying name.

H : DCI Support This section describes the additional image analysis displays that become available when the VIEW_XR_DCI option is installed. Adding this option also adds support for the XYZ colour space and for 12-bit pixel data.

H.1 CIE Colour Chart (Not available in PQA Mode) The CIE Colour Chart is an x,y plot of the chrominance of each pixel as represented in XYZ colour space, presented as a trace drawn over a standard background. The enclosed area within this background indicates the full range of X,Y values that correspond to colours which are visible to the human eye. In one version of the display, this area is also coloured to indicate the colours represented by the different X,Y values.

Figure H-1: CIE Colour Chart The chart has some special properties compared to other measures such as gamut charts, histograms or the vectorscope. In particular: Each colour that the eye can see is represented by a single point on the chart. The point representing a colour is independent of the colour primaries that will be used to display the colour. It is also independent of the luminance. The colours that can be reproduced by any set of three display primaries all lie within the triangle formed by linking the points representing the colours of the individual primaries. The CIE Colour Chart is of particular value in assessing the effect on the colour depth of video generated for transmission in SD or HD from Digital Cinema source material, because the RGB primaries specified for the DCI Reference Projector define a noticeably wider colour range than can be produced with the display primaries specified for SD and HD. (There are also differences between the colour ranges supported by the display primaries defined for PAL, NTSC and HD but these differences are significantly smaller than those between these primaries and those defined for Digital Cinema.) OmniTek OTR 1001 User Guide, v3.0

H-1

Another major application for the Colour Chart is in assessing the effect on the colour depth of displaying the video on a particular projection system. To this end, the OTR 1001 has the facility to overlay the chart with triangles representing both the colour gamut for which the video has been prepared (as defined by the ‘Input’ primaries) and the colour gamut associated with the user’s choice of ‘User’ primaries. This second triangle might for example be used to indicate the colour gamut of the system on which the video is to be displayed. Triangles representing standard sets of display primaries such as those associated with PAL, NTSC, HD and Digital Cinema are available for selection from a menu. CIE Charts can be displayed for the whole frame or for individual lines as required, and filters can be applied in the same way as for Waveform displays. Another option is to display a ‘Luma Masked’ version of the CIE Chart, covering just those pixels with the luma value within a specified range (selected by the user). Labels showing the selections that have been made can optionally be shown in the corners of the display. The same general steps are involved in working with this display as are used with other Views. (See Section E.1)

Selection The CIE Colour Chart Display is one of the displays offered within the GAMUT category. Control Panel

Configuration Issues The following Configuration settings affect the display of the CIE Colour Chart: Input Primaries Where the video being analysed is in YCbCr format, the OTR 1001 automatically selects the Input primaries associated with the video standard that is detected. But where the input is in RGB or XYZ format, it is not possible to determine the appropriate set of primaries automatically. The primaries to apply in each case need to be set on the Video Config page of the Config window.

H.2 Histogram The Histogram display presents colour histograms of the video that is currently being analysed. Parts of the signal that lie outside the required gamut are shown in red. The analysis is applied either to full frames of active video or just to the Region of Interest where this is enabled (see Section E.2). Where the VIEW_3D option is installed, the Histogram display may also be used to compare the luma and chroma levels in the left-eye and right-eye images of Stereo 3D video: see Section I.8. The histogram displays provide a detailed and accurate method of assessing colour gamut. Unlike traditional displays that simply indicate that a signal is out of gamut, these histograms allow you to see to how far out of gamut the signal goes. The histograms for the different colour components may be displayed overlaid, stacked or in a parade format, while the scale against which they are shown can be either linear or logarithmic. A cursor may optionally be added to the display, along with a read-out of the value for each colour component at the current cursor position. The same general steps are involved in working with this display as are used with other Views. (See Section E.1)

I : Stereo 3D Analysis and Camera Alignment This section describes the tools for analysing Stereo 3D (S3D) video that become available where the VIEW_3D option is installed and enabled, and the assistance that the OTR can offer towards camera alignment when either the VIEW_3D option or the ALIGNMENT option is installed. All video formats are supported including 3G Level A and 3G Level B (with the appropriate VIDEO_xx options: see Section V). The 3Dtools described in this section allow: Visual comparison of the left and right images Depth mapping and analysis Assessment of luma and chroma differences between the left and right images The Camera Alignment tools comprise a set of meters that compare camera set-up details such as rotation, zoom and colour gain either between the cameras providing the left-eye and right-eye images or between a single camera and a reference image. These tools are described in Sections I.8 and I.9. Camera Alignment data is also included in the Status displays described in Section E.6 (see also Section I.10). The S3D video may be delivered either as separate Left and Right image streams or in Side-BySide (SbS) or Top + Bottom (TaB) formats. The OTR also includes various flip options for handling S3D video taken from a mirror rig. Notes: (i) The 3D facilities described here also require the VIEW_2 (Simultaneous Monitoring) option to be installed. However, this should never be an issue as any sale of the VIEW_3D option will also include the VIEW_2 option if this is not already licensed. (ii) Where the GEN_2 option is installed, the OTR can also be used to generate S3D video – see Section Q.12. (iii) A white paper on 3D Monitoring and Correction is available on our website at www.omnitek.tv/3D_White_Paper.pdf (iv) Many of the facilities described in this section aren’t available when the OTR is in PQA Mode (described in Section S). However, the single camera alignment facilities described in Section I.8 do remain available.

Terminology Disparity

The amount by which the location of an image feature in the Right-eye (test) image is displaced relative to the location of the same image feature in the Left-eye (reference) image. Vertical disparity is measured in lines: horizontal disparity can be measured either in pixels, or in metres on the screen on which the image is displayed or as a percentage of the screen width. Where disparity is mentioned in relation to perceived depth, it is referring to horizontal disparity, positive values of which correspond to positions behind the screen, while negative values correspond to positions in front of the screen.

OmniTek OTR 1001 User Guide, v3.0a

I-1

Depth

The distance a 3D object appears to be from the screen plane. Positive values correspond to positions behind the screen; negative values correspond to positions in front of the screen.

Depth Budget

The desired range of depths within which all 3D objects should appear, expressed either in terms of a maximum (most positive) and a minimum (most negative) disparity or a maximum (most positive) and a minimum (most negative) depth.

I.1 Stereo 3D Overview Stereo 3D video produces the effect of 3D by deploying the brain’s capacity to interpret parallax between right- and left-eye images of the same object as a single object at a distance from the viewer. For the viewer’s brain to merge two images into one 3D image: 1. The ‘disparity’ (see above) must lie between the value representing the closest object (typically no less than about 1m in front of the viewer) and the value representing the farthest object (usually taken to be at infinity) 2. The colorimetry of the two images must match. The OTR offers a variety of ways to display the depth information that can be deduced from the two signals, together with a range of ways to compare the colour information in the two component video signals. It also offers a choice of Picture modes through which to see the effect of combining the images. Other facilities include automatic read-out of the coordinates in the viewer’s world of any point you pick with the crosshair cursor (i.e. the x, y, and z coordinates that the selected item will appear to have relative to the viewer) and the ability to limit the area being analysed to a specified Region of Interest. The crosshair cursor and/or its coordinates in the viewer’s world are shown on many of the displays described in this section. This information also appears in the Properties control. Any change in the position of the crosshair cursor in any of these displays automatically causes all references to this cursor to be updated to reflect the new position in the viewer’s world coordinates. The Regions of Interest shown on the left- and right-eye images are similarly linked by an offset corresponding to the measured disparity. The right- and left-eye images are typically provided as separate inputs to the OTR, but may also be delivered Side-by-Side (SbS) or Top + Bottom (TaB) or taken from 3G Level B Dual-Stream video. Where separate inputs are used, the user specifies which input is providing the left-eye image and which the right-eye image. The thumbnails on the Status Bar automatically switch to show the lefteye image to the left and the right-eye image to the right. Where the video is taken from a mirror rig, the user specifies – for both Left and Right image streams – whether the image is in the normal orientation, flipped horizontally or flipped vertically. The use of a mirror rig typically also means that the colours are generally less bright in the image that has been through the mirror. Such differences in colour adversely affect the OTR’s ability to match objects across the left-eye and right-eye images. The process of matching objects is also adversely affected by any vertical disparity between the images. However, the OTR is able to determine the corrections that need to be applied in each case, and ‘Auto gain control’ and ‘Auto correct vertical disparity’ options are offered. When selected, these options can significantly improve both the quality of the 3D depth analysis and the OTR’s assessment of camera set-up issues such as differences in zoom and camera roll. Important: Processing Stereo 3D video takes significant resources. In particular, it is not possible to both analyse Stereo 3D and to capture images at the same time. The OTR therefore allows you to enable and disable 3D monitoring as required: this is described in Section I.2. I-2

OmniTek OTR 1001 User Guide, v3.0a

I.2 Enabling 3D Monitoring Before any of the 3D facilities described in this guide can be made available: 3D Monitoring needs to be enabled for the machine as a whole, and The format in which the S3D video is delivered needs to be defined. These actions use the 3D Settings section of the System page of the Config window (the other settings of which are described in Section T.4).

Figure I-1: 3D Settings section of the System page of the Config window. While 3D Monitoring is enabled, the OTR’s Capture facilities are disabled. However, the live input received on either input can still be passed through to the SDI outputs (as described in Section P.4). There is also the option to pass-through the signals on both inputs. The steps used to enable 3D Monitoring are given below, along with the steps used to disable 3D Monitoring (and re-enable the Capture facilities). Control Panel

Defining the 3D Video Format The OTR also needs to be configured for the format in which the Stereo 3D video is delivered. Stereo 3D video can be delivered in any of the following formats As separate Left and Right image streams, one delivered to Input 1 and the other to Input 2 With the Left and Right images delivered Side-by-Side either to Input 1 or Input 2 With the Left and Right images delivered Top + Bottom either to Input 1 or Input 2 As taken from a mirror rig, leaving either the Left images or the Right images flipped either horizontally or vertically. Control Panel

Mouse & Keyboard

To set the 3D video format: 1. Call up the System page of the Config window. 2. Select Channel Sources within the set of 3D Settings on that page, and select the source option appropriate to the video that is to be processed from the drop-down menu. 3. Set the Left Camera Flip Mode option within the set of 3D Settings according to the orientation of the left-eye images that are to be processed – Off (normal orientation), H(orizontal) Flip, or V(ertical) Flip. 4. Set the Right Camera Flip Mode option within the set of 3D Settings according to the orientation of the right-eye images that are to be processed – Off (normal orientation), H(orizontal) Flip, or V(ertical) Flip.

Applying Auto-correction Differences in colour gain and vertical disparity between the left-eye and right-eye images significantly diminish the OTR’s ability to match items across the left-eye and right-eye images. However, the matching algorithms that the OTR applies are generally able to determine corrections that improve the number of matches that can be made and Auto Gain Control and Auto correct Vertical Disparity options are offered that apply these corrections. Switching between enabling and disabling these options will show how effective they are being. Control Panel

Mouse & Keyboard

To enable Auto Gain Control/Auto correct Vertical Disparity: 1. Call up the System page of the Config window. 2. Tick the Auto Gain Control / Auto correct Vertical Disparity option within the set of 3D Settings on that page. To disable Auto Gain Control/Auto correct Vertical Disparity: Clear the tick beside the Auto Gain Control / Auto correct Vertical Disparity option within the set of 3D Settings on the System page of the Config window.

I.3 Visual Comparison of S3D Left/Right Images When 3D Monitoring is enabled, the Picture display (described in Section F) is extended to offer a set of variants in which the two inputs are combined in different ways to form a single image. The ways the inputs may be combined are as follows: As a checkerboard of alternate sections from the two images. Where there are no luma or chroma differences between the images, single colour areas of the resulting image will look completely smooth. As the sum of the two signals. Items in the combined display typically have blurred edges, corresponding to the disparity between the positions of these edges in the two signals. The width of the blurred edge gives a visual impression of the item’s distance in front of or behind the screen. (The blurring is zero for items located in the screen plane.) As the difference signal. The difference signal also picks out the disparity between the edges of items within the image. As an anaglyph, for viewing in 3D through red/cyan glasses. The left-eye image is rendered in shades of red, the right-eye image is rendered in shades of cyan, then the two images are overlaid. Alternating between the Left and Right images. Here the disparities are reflected in the amount of movement seen. In addition, differences in vertical alignment appear as movement up and down the screen, while differences in luma and chroma levels give rise to a flashing effect.

Anaglyph – Left image displayed as tones of red; Right image displayed as tones of cyan. (The resulting image is seen as a threedimensional image in shades of grey.) Alternate Left & Right – Images from the signal inputs are displayed alternately. The number of frames for which each image is displayed is set as the Left/Right Toggle Interval.

I.4 Depth Analysis of Stereo 3D video The OTR offers a range of displays analysing the depth information determined from the left and right image streams. These displays are presented through three additions to the Picture category of tile views: Depth Map: This can be set to display all the pixels in the image for which the depth was calculated. Alternatively, the display can be limited to just those pixels for which the calculated depth is outside the specified Depth Budget. Depth Plan: This can be set to show the distribution of objects from front to back as seen from above or as seen from one side. Another option is to display the disparity values that were determined as a plot across the width of the screen. Depth Map Histogram: This displays a histogram, showing the distribution of disparity values across the whole image and to what degree these are within the desired Depth Budget. These displays are described in Sections I.5, I.6 and I.7, respectively. The displays all use a colour ramp to indicate position relative to the specified Depth Budget. All points nearer to the viewer than the minimum distance are coloured red; all points beyond the maximum distance are coloured violet. The colour ramp is used to colour points located between these two distances.

Background The distance from the screen that an object in a Stereo 3D video will appear to be to the viewer is readily calculated by simple geometry. All the calculation requires is knowledge of the width of the screen, the viewer’s distance in front of the screen, how far apart their eyes are (the ‘Interocular distance) – and knowledge of the ‘disparity’ between the position of an identifiable point on the object – in the Left-eye image and its position on the same line of the Right-eye image. The result of the calculation for any point gives the ‘z’ component for this point in a set of ‘Viewer World Coordinates’, the ‘x’ and ‘y’ components of which are calculated assuming that the viewer is sitting centrally with their eye level half way up the screen. (The (0, 0, 0) point for these viewer coordinates is the centre of the screen.) The width of the screen, the viewer’s distance in front of the screen and the Interocular distance remain the same throughout the video and are recorded as part of the System settings (see Configuration, below). In analysing each frame of the video, the OTR searches along each line of the video for features that can be matched between the left-eye image and the right-eye image. The range of the righteye image that is searched for a matching feature is given by the values for the Search Minimum and the Search Maximum recorded in the System settings. These minimum and maximum values set the limits on the range of disparity values that will be determined. They also correspond to the nearest to the viewer and the farthest behind the screen that the OTR will pick out items to report. Any objects with disparities outside this range in the video will not be reported.

OmniTek OTR 1001 User Guide, v3.0a

I-9

Also recorded in the System settings are values for the Minimum Budget and the Maximum Budget. These need to be set to define the depth range in which items of interest should appear, commonly referred to as the Depth Budget. Disparities outside this range are regarded as being in error. The range of disparities recorded as the Search Minimum and the Search Maximum should be very much wider than that recorded as Minimum Budget and the Maximum Budget in order to allow attention to be drawn to objects that appear outside the Depth Budget.

Configuration Issues The 3D Depth Analysis described in this section needs the following parameters to be set correctly in the 3D Settings section of the System page of the Config window: Allow 3D Monitoring Allow 3D Monitoring must be ticked within the set of 3D Settings. Analyser Source The port or ports on the OTR into which the S3D video is to be fed need to be set as the sources for Analyser 1 and/or Analyser 2 as appropriate. For details, see Section T.4. Channel Sources and Flip Mode Use the Channel Sources option to specify: the format of S3D video that is being used (separate Left and Right image streams, Sideby-Side or Top+Bottom) where the Left and Right images are to be taken from Use the Camera Flip options to specify whether either image is flipped either horizontally or vertically. (For further details, see Section I.2.) Note: If the Left and Right images have been wrongly assigned, items that you expect to appear in front of the screen will appear to be in the far distance, and items that you expected to be in the distance, appear to be very close.

Auto-Correction Options The OTR offers auto-correction of differences in colour gain and vertical disparity between the left-eye and right-eye images, which in many cases can significantly improve the OTR’s ability to match items across the two images. Select these facilities by ticking the Auto Gain Control and Auto correct Vertical Disparity options within the 3D Settings section on the System page of the Config window. (For further details, see Section I.2.) Viewer and Screen Parameters For the depths (and other values in the viewer’s world coordinates) that are calculated to be meaningful, the Viewer Distance (in front of the screen), the Interocular Distance (between the viewer’s eyes) and the Screen Width need to be set correctly. The units for these measurements are metres. Note: In accordance with SMPTE recommendations, the defaults for these values are: Viewer Distance 1.75m; Screen Width 0.93m; Interocular distance 0.064m. Disparity/Crosshair units Disparity values can be expressed either in pixels, or as a distance across the screen, or as a percentage of the screen width. While 3D is selected, these units are also used in the Input section of the Properties control to express the location of the crosshair cursor (see Section E.2). Maximum/Minimum Search These values, together with the Depth Map Increment (see Section T.4), set the scope for the OTR’s search for matching features in the left- and right-eye images (see ‘Background’ above). These values can be expressed either as disparities or as the equivalent distance in the viewer’s world coordinates. Maximum/Minimum Budget These values define the Depth Budget (see ‘Background’ above). These values can also be expressed either as disparities or as the equivalent distance in the viewer’s world coordinates. Note: Infinity is expressed by setting the disparity to the interocular distance.

I.5 Depth Map The Depth Map uses colour to show how far the various features in the current Stereo 3D image are away from the viewer. The map is created by colouring each pixel for which the OTR determined the disparity. Points at which the disparity was found to be less than or equal to the Minimum Budget disparity are coloured red; points with disparities greater than or equal to the Maximum Budget disparity are coloured violet; and points between are coloured using the standard colour ramp. The proportion of points for which the disparity was outside the specified limits is listed in the Status display (see Section E.6). Two versions of the Depth Map may be shown: one in which all the points for which disparities were determined are displayed; and another – the Depth Error Map –which just displays the points that were outside the specified Depth Budget. A further option is to display the scene for which the disparities were determined as a greyscale image behind the Depth Map.

I.6 Depth Plan The Depth Plan provides various views of the depths determined from the Stereo 3D right- and left-eye images. These include views as if you were looking down on the scene from above or from the side and a projection that can be viewed from all different angles. All the positions are determined as for the viewer i.e. in Viewer World coordinates. The view from above is referred to as the Viewer World (Plan); the view from the side is referred to as the Viewer World (Elevation). The third display is referred to as the Real World Projection. The Depth Plan can also be set to show a ‘Disparity View’ in which the disparity values determined from the images are mapped across the width of the screen. Superimposed on all four plots are lines/planes representing the screen plane and the limits of the specified Depth Budget. On three of the displays, there is also the option of a read-out of the Viewer World coordinates of the point at or nearest to the current crosshair position. Viewer World (Plan) view

Figure I-10: Viewer World (Plan) view. The Viewer World (Plan) view is an x,z plot of the positions determined for the current image. This presents the depth information as if looked at from above. The range of depths displayed can be adjusted by setting the Zoom level in the Properties control (see ‘Display Properties’ below.) Note: The display is limited to items within the field of view captured in the image. As a result, the points shown all fall within a cone spreading out from the viewer’s position at the tip of the cone. Note also that clicking on the display with a mouse will normally select the nearest point at which the disparity has been determined. However, if required, you can select a point on the x,z plane (x, 0, z) by clicking (or clicking and dragging) while holding down the Ctrl key.

Real World Projection

Figure I-13: Example Real World Projection. The Real World Projection allows the current scene to be seen from all different angles. The framework for the display comprises four lines emanating from a point representing the viewer’s position, plus a set of planes representing the Depth Budget minimum (in red), the screen plane (outlined in white) and the Depth Budget maximum (in violet). The pixels for which depths have been calculated are slotted into this framework, giving the required Real World Projection. The basic framework can be rotated both left to right and up & down, thereby allowing the scene to be seen from all possible angles. You can also move in and out on the images. For details, see ‘Rotate/Zoom’ below. The OTR also offers a sequence of standard views which can be viewed in turn by taking the Next View option on the Button Bar (or in the Properties control).

I.8 Camera Rig Alignment Assistance with camera rig alignment is available on any OTR on which either the VIEW_3D or the ALIGNMENT option is installed. The principal tool is the ‘3D Meters’ display described below. Additional colour gain and lift information is provided by the ‘3D Chroma Sabres’ display, described alongside other Luma/Chroma Comparisons in Section I.9. Two set-ups are supported: A pair of cameras, set-up either to focus on a test chart or to capture a 3D scene A single camera, set-up to focus on a test chart (or some other reference scene) which has previously been captured by the camera you are using as a reference. For single camera alignment, the output from the camera under test (and previously from the reference camera) needs to be fed into SDI Input 1 or Eye Input 1, depending on how the Analyser source is set. When aligning a pair of cameras, the output from one camera is typically fed into either SDI Input 1 or Eye Input 1 (again depending on how the Analyser source is set) and the output from the other similarly fed into SDI/Eye Input 2. This arrangement is always used on systems without the VIEW_3D option or where 3D Monitoring is switched off, but if 3D Monitoring is enabled, the Channel Source and Flip settings on the System page of the Config window become important as the OTR will pick out a Left and Right image to compare based on these settings.

3D Meters Display This display comprises a set of meters that measure differences between two images. Depending on the set-up, the meters either compare: A Right-eye image from Stereo 3D video against the corresponding Left-eye image; or Input 2 against Input 1 (where 3D Monitoring is not enabled); or Input 1 against a previously captured Reference image.

Figure I-18: 3D Meters display

I-20

OmniTek OTR 1001 User Guide, v3.0a

The meters show: What range of depths are covered (Stereo 3D video only). Whether the cameras are vertically aligned, and if not, how far out they are (in lines). Whether there are signs of camera rotation (roll). Whether the cameras are using the same or different zooms. How sharp the images are, with the bottom half of this meter showing the sharpness of the image being compared and the top half showing the sharpness of the image against which it is being compared. Ideally the markers should one above the other, indicating that the images are equally sharp. The difference in colour gain and lift between the image under test and the one against which it is being compared, shown separately for the individual colour components. The meters are marked to show the difference between acceptable values and values outside the limits specified on the Video Config page of the Config window, while ‘traffic lights’ to the left of each meter indicate whether the current status is Good (green), Warning (yellow) or In Error (Red). Whether the display is used to compare two live images or to compare one live input against a reference image is controlled through options on the Button Bar. Other buttons on the Button Bar capture the reference against which input from a single camera may be compared, and select the type of image to be analysed because different point matching algorithms need to be applied depending on whether the image of a test chart or a 3D scene is analysed. Note: The values shown in this display are independent of any corrections made as a result of the Auto Gain Control and Auto correct Vertical Disparity options being selected, except that when the comparison is being made of the Right-eye and Left-eye images of a general scene, having these options selected increases the number of points available for use in the calculation of the other parameters and hence the accuracy of these measurements.

Capture Reference (See ‘Single Camera Alignment, below) Alignment Sources Where 3D Monitoring is enabled, this option selects between comparing a Right-eye image against the corresponding Left-eye image (Right vs Left) and between comparing the image on Input 1 against a previously captured reference image (In1 vs Ref). When 3D Monitoring is not enabled, the choice is between the image on Input 2 against the image on Input 1 (In2 vs In1) and the image on Input 1 against the reference image (In1 vs Ref). Note: The In1 vs Ref option requires Analyser 1 to take its source from SDI Input 1 (or Eye Input 1 if installed) and Analyser 2 to take its source from the built-in generator. If necessary, the OTR will automatically re-assign the Analyser sources. Where this happens, the views displayed in other tiles will also reflect the inputs that are now selected.

I.9 Luma/Chroma Comparisons The toolsets provided for 3D analysis and camera alignment both include a ‘3D Chroma Sabres’ display that assesses, for each colour component, differences in gain and lift either between two live images or between a live image and a saved reference image. In addition, when 3D is enabled, extra settings are available on the Waveform, Vectorscope and Histogram displays that allow the comparison of the luma and chroma content of Left and Right images. These displays all feature a red trace for the left-hand signal and a cyan trace for the right-hand signal. Differences between these traces provide a measure of the difference in luma/chroma levels between the two component signals, and hence indicate the size of adjustment that needs to be applied either to the signals themselves or to the cameras capturing the images. All the traces are displayed in real time, allowing you to see immediately the effect of any chroma adjustments you make to the incoming video. Note: The displays described in this section work with the raw pixel data. They are not changed by the selection of the Auto Gain Control option but selecting this option (and the associated Auto correct Vertical Disparity option) may improve the accuracy of the Chroma Sabres display through increasing the number of points that are matched.

1. 3D Chroma Sabres The focus of the 3D Chroma Sabres display is on differences in the Gain and Lift suggested by comparing the RGB values of points that can be matched across the two images.

Figure I-20: Example 3D Chroma Sabres display

OmniTek OTR 1001 User Guide, v3.0a

I-25

The display comprises a set of diamond-shaped plots, one for each colour component, comparing the colour values at each pixel in the ‘test’ image i.e. the image being compared (the Right-eye image in the case of Stereo 3D video) against those of the corresponding pixel in the reference image (the Left-eye image in the case of Stereo 3D video). Figures are given below each sabre for the average percentage difference in Gain and Lift (as determined by comparing the right-eye image against the left-eye image). If the Gain and Lift applied to the two images were identical, each of the three plots would comprise a single vertical line running from the bottom of the diamond to the top. But in practice, the plots tend to feature a mass of points scattered around the vertical but biased either to the left or the right. To interpret these distributions, a best-fit line is drawn through the points, the features of which are interpreted as a difference in Gain and Lift between the test image and the reference image. Where the line leans to the right, the Gain is greater in the test image (i.e. the Right-eye image in the case of Stereo 3D video) and less in the reference image (i.e. the Left-eye image in Stereo 3D video): this is shown as a positive value. Where it leans to the left, the Gain is greater in the reference image: this is shown as a negative value. The Lift is given by the offset from the origin at the bottom of the plot – again positive when in the right half of the plot and negative when in the left half. Adjustments made to the set-up of the cameras from which the images are being taken are immediately reflected in the Chroma Sabres display, making this display useful in Camera Rig Alignment (see Section I.8).

3. Colour Comparison on the Vectorscope Display The basic Vectorscope display (see Section E.4) is a vector representation of the incoming waveform, in which the distance of any point from the centre of the display reflects the luma value of the corresponding pixel while the pixel colour is represented by the orientation of the point with respect to the centre of the display. To allow colour comparison between Left and Right images, the OTR Vectorscope display has a 3D View mode in which the vector representation of the waveform from the Left image(shown in red) is overlaid by the vector representation of the waveform from the Right image (shown in cyan).

I.10 Error Reporting Limits can be placed on aspects of 3D video such as the range of depths covered and on the extent to which the Right-eye image differs from the Left-eye one (reflecting differences in camera setup). Similar differences between a non-3D image and a chosen reference image also provide camera setup information. As with other aspects of video status and error reporting, current values are reported through the Status Overview (called up as described in Section E.6) while the circumstances under which these values are reported as being in error are set within the 3D settings section of the Video Config page of the Config window (called up as described in Section T.2). The status details are also displayed in the form of a Status Summary (available via the Video button on the Status View Button Bar).

Figure I-31: 3D and camera setup data shown on the Video Status Summary pages. The data is also shown graphically in the 3D Meters display, which is described in Section I.8. Picture Analysis: Measurements The Near error points and Far error points values give the number of the pixels for which the horizontal disparity was either less than (or more negative than) the Budget minimum or greater than the Budget maximum, respectively, as a percentage of the total number of pixels for which the horizontal disparity was determined. The Points not matched value gives the number of pixels for which the horizontal disparity could not be determined as a percentage of the total number of pixels in the screen display. Use the Video Config page of the Config window to specify the limit on acceptable maximum values for each of these parameters and whether instances should be reported as errors or just a warning given. Note: The OTR only looks for disparities in the range set by the Search minimum and maximum set on the System page of the Config window. Items in the image for which the disparity lies outside of the Search range will be missed and will not be recorded as errors. It is therefore important to ensure that the Search minimum and maximum are set appropriately. Picture Analysis: Image Sharpness The OTR determines image sharpness on a scale between 0 (very soft) and 1000 (very sharp) from the gradient of the edges it detects within the image. These values are reported in the Status Overview as Left picture sharpness and Right picture sharpness. (Where a single image is being compared against a Reference image, the Left picture sharpness reports the value for the Reference image, while the Right picture sharpness reports the value for the test image.) The difference between these sharpness values is reported as the Sharpness delta. The Sharpness delta limit setting on the Video page of the Config window allows you to specify acceptable limits on this difference and whether an error is reported or just a warning given when this difference is exceeded. Typically a Sharpness delta of more than 100 gives rise to a noticeable difference between the images.

Rig Alignment Camera set-up parameters determined when either the input from one camera is compared against a reference image or when the Right-eye image of a Stereo 3D pair is compared against the Left-eye image (selected through the 3D Meters display described in Section I.8): Camera rotation (roll), expressed in degrees. The percentage difference in the zoom levels. Any horizontal offset between the images (expressed in the current disparity units, as set on the System page of the Config window). Gives meaningful results where a test chart is used. Any vertical offset between the images (expressed in lines). Use the Video Config page of the Config window to specify the limit on acceptable deviations and whether larger deviations should be reported as errors or just a warning given. Picture Levels Another comparison that the OTR makes is of the colour components at matching points, from which it is able to deduce any differences between the colour gain and lift that has been applied to the test (Right-eye) image over those that have been applied to the reference (Left-eye) image. Acceptable limits and whether larger deviations should be reported as errors are specified through the Maximum Gain and Lift settings on the Video Config page of the Config window. Set-Up and Disparity Constants Both the Status Overview and the Status Summary display basic information about the 3D setup, covering: The sources that have been defined for the Left and Right channels The dimensions defining the Viewer’s World (in metres) The limits that have been defined for the Disparity Search and the Depth Budget (expressed in pixels, as a percentage of the screen width, and as the physical distance on the defined screen) These values are set on the System page of the Config window. Selected Point For Stereo 3D video, values are also displayed for: The Viewer’s World Coordinates at the point currently selected by the crosshair cursor The horizontal disparity at that point (expressed in pixels, as a percentage of the screen width, and as the physical distance on the defined screen). Where necessary, these values are extrapolated from nearby measured points.

J : Event Handling The OTR 1001 offers a range of responses to specific conditions or transitions within the video stream that is being analysed. One response is to generate a list of these conditions and transitions as they occur, known as an ‘Event Log’. The OTR 1001 offers both a listing of such events as they happen (a ‘Live’ log) and the opportunity to save sequences of these events for further analysis and/or recording in an XML file. The OTR 1001 can also respond to events by generating an alarm and/or transmitting an SNMP alert. These functions all work independently. In addition, separate logs can be created of Momentary & Short-Term Loudness values (see Section J.2) and of captions embedded in the text and associated settings (see Section J.3). Both log entries and SNMP alerts can be marked with the machine time and/or VITC, ATC or LTC timecodes where present.

J.1 Event Logs Overview The entries in an Event Log are all triggered by ‘events’. These events may correspond to a marker such as timecode or a closed caption being detected within the input video stream but they are most commonly associated with the detection of an error condition or the transition of the video stream into or out of a particular state. The conditions under which an error is reported are set through the Video Config and Audio Config pages of the Configuration window. These pages list the parameters of the video that your OTR system is able to monitor, and allows you to specify for each parameter: 1. The conditions under which the OTR should report an error 2. The level of error that should be reported – from ‘OK’ through ‘Warning’ to ‘Error’ 3. Whether the error should be logged in the ‘Event Log’ and/or cause an Alarm to be generated and/or generate an SNMP alert. The following sections describe the different ways in which the OTR 1001 may respond to events. They also describe the options that are available for recording sections of the Live log on disk as ‘Session logs’ and for analysing these logs.

Event Log Display The Event Log is one of the analyses offered under the STATUS category. The Event Log automatically offers a ‘Live’ log, listing events as they happen on the currently selected input video stream. It can also display the results of one or more ‘logging sessions’, which may be started and stopped either manually or at specific points in the video being analysed. These logging sessions are started and stopped independently and may run concurrently. The resulting ‘Session logs’ can also be saved as XML files and analysed to show the frequency of the different types of event.

The upper area of the display is given over to a ‘Session List’ of the logs that are currently available for inspection, together with any logging sessions that have been set up but not yet completed. The lower area is used to display details of the log that is selected in the upper part of the screen. This lower display may comprise either: an historical ‘Event List’ (as shown above) or a ‘Event Frequency tree’, giving an analysis of the frequency at which particular types of event have occurred, or a snapshot of the status at the start of the logging session, or a snapshot of the status at the end of the logging session. Further details of these displays are given below. Note: If a scroll bar is shown at the bottom of the display, there are further columns of information to be displayed.

Upper Part of the Event Log

Figure J-2: Sample Session List The upper part of the Event Log display comprises the Session List. The top entry in this list is always the Live log, which is automatically triggered to start running when the Event Log is selected for display. The other entries refer either to logging sessions that have been set-up since the OTR 1001 was last turned on (or reset) or to Session logs that have been loaded from disk. To make the Live log easy to pick out, its entry is shown against a white background. The information that may be displayed about any logging session includes: The name of the log; Its state (‘Pending’ (i.e. waiting to start), ‘Triggered’ (i.e. started), ‘Completed’ etc.); The type of trigger used for the session (where applicable); and Which input was analysed; In the first column of each entry is a coloured icon that indicates its error state as follows: Green

Free from error or, at least, no errors reported so far. (Note: Whether a user-defined session contained any errors is only reported once the session has been completed.)

Red

One or more error events have occurred

The coloured icons provide a simple ‘green = good’; red = ‘not good’ indication in analogy to traffic lights. Guided by these markers, and the information shown in the Event List (see below), it should be straightforward to determine both what errors have occurred and where these occurred. Control Panel

J.2 Loudness Logs Loudness Log Display

Figure J-9: Example Loudness Log display The Loudness Log display provides a way of recording Momentary and Short-Term Loudness values on disk for analysis outside the OTR application. Several such logs can be recorded at the same time. These logs can either be recorded manually or they can be created to a defined schedule that caters both for one-off logs and for logs created as part of a continuous sequence. The start-point of a scheduled log or log sequence is defined either by a specified time on the OTR’s built-in clock or by a specified timecode embedded in the video. The end-point can be defined similarly: alternatively you can define the duration of an individual log e.g. within a continuous sequence. The display comprises a list of Loudness logs that have been defined since the display was called up. Each entry in the list shows whether the log is pending i.e. waiting to start (hourglass symbol), recording (red blob) or recorded (file symbol) – together with whether it was a ‘Single’ (i.e. one-off) log or part of a ‘Continuous’ sequence, the triggers for the start and stop, and, once it has completed, the file name under which it is stored. The logs comprise Momentary,‘Sliding’ (Short-Term) and ‘Integrated’ Loudness, and Loudness Range values as measured every second and calculated for each possible interpretation of the input audio stream (as defined on the Audio Inputs page of the Config window). These values are recorded along with the PC time and any timecodes embedded in the video. The data that is collected is written as a CSV file to a Loudness Logs folder either within your User area on the OTR or within your chosen Log Files Folder (see Section U.2). The filename it is given records the date and PC time at which the log finished. The Manage Disk facility described in Section U can then be used to copy this and other Loudness Logs, for example to a USB stick, for analysis outside the OTR application.
