Chapter 1: Logo Utilities for 6800 Series Modules Graphic and Logo Creation

Graphic and Logo Creation

Creating and Loading LogosYou can load customer-designed logos into 6800 series modules using the Leitch Logo Graphics Conversion and Download Utilities. These utilities allow the conversion of customer-created graphics files from a variety of industry-standard graphics formats into the format required. You can then download the converted files from a computer into the module, using a serial port interface.

Creating Graphics for Logo Use

Creating Master Artwork

Create the logo artwork using a standard drawing or paint program. The LogoMotion Utilities require two graphics files: one for the video (Fill) signal and one for the Key signal to generate an MGI file.

The LGI-6801 uses both the Fill video signal and the Key signal. The VES-6801 uses only the Fill signal.

If you are not familiar with the concept of keying and Key signals, we recommend that you research this topic thoroughly before proceeding to create graphics artwork for logo use. Linear keying is perhaps the largest challenge in the creation of quality logos for on-air use. Leitch has available several Applications Notes that describe Keying in detail. Contact your local Leitch representative, or visit us at http://www.leitch.com.

Most drawing/paint programs allow you to select the pixel resolution and color depth. These selections can greatly affect the quality of the final logo. See “Selecting the Pixel Size and Color Resolution of the Graphic” on page 5 for further information.

Both the Fill and the Key signals must be sized and processed identically. Otherwise, the two will not align, and the keyed result may appear misaligned. Many graphics programs provide for the manipulation of many simultaneous channels together, simplifying this task. On some systems that do not provide for Alpha or Key channels, a separate graphics file must be created and processed identical to that of the Fill graphics file.

The 6800 series module does not create the logo. The module acts only as the recorder, storage, playback, and Keyer for externally created logos.


Graphic and Logo Creation Chapter 1: Logo Utilities for 6800 Series Modules

Selecting the Pixel Size and Color Resolution of the Graphic

Most drawing/paint programs allow you to select the size of the graphics file, which is typically measured in pixels. The choice of pixel resolution can affect the quality and size of the graphics file.

6800 series modules are serial digital products that store all logos according to the CCIR-601 format. Another term commonly used to denote the CCIR-601 format is 4:2:2(:4). This format defines a horizontal video line to be 720 pixels wide, with the number of vertical pixels (also referred to as lines) depending on the line standard in use. For 525/60 systems, the number of active video lines is 486, and for 625/50 systems, the number of active video lines is 576.

A video Fill Key signal is stored in full color, with three channels of video components. For the purposes of this discussion, we will assume that the three channels are red, green, and blue (RGB). The second video image stored is a linear Key signal (a monochrome signal composed of a single luminance channel). Other terms used to denote the linear Key signal are: Key, Alpha, and Matte channel.

For CCIR-601 purists: Although the CCIR-601 specification defines the three video channels as Y/Cb/Cr, most graphics systems operate only in the RGB domain. The Logo Utilities automatically convert from the RGB domain to Y/Cb/Cr domain. The Cb/Cr channels have one-half the number of pixels as the Y channel. Because the Utilities require the full number of pixels in the RGB domain, they will correctly create the Y/Cb/Cr pixels for the final logo file.

The Logo Utilities work with all pixel resolutions and color depths. Best results can be achieved with specific pixel resolutions and color depths.

The “ideal” pixel resolutions for the 6800 series modules are:

• 525/60 operation: 720 horizontal pixels x 486 vertical pixels/lines

• 625/50 operation: 720 horizontal pixels x 576 vertical pixels/lines

The “ideal” Key Fill color depths are:

• Fill graphic images: 24 bits per pixel (8 bits per RGB)

• Key graphic images: 8 bits per pixel (luminance or grayscale only)

The VES-6801 can store 30-bit RGB images as 10-bit Y/Cb/Cr.

It is better to operate in the highest possible resolutions, rather than lower ones. The Logo Utilities automatically scale all graphic files to the correct resolutions for use in 6800 series modules.

The LGI-6801 stores two video images for each logo (Fill and Key signals). The VES-6801 stores one image for each logo (Fill only).



Aspect Ratios and the Ubiquitous Square Pixel

The aspect ratio for almost all video screens in the television and graphics world is typically 4:3. This implies that the horizontal width is 1/3 larger than the vertical height. However, a pixel in the television world is not the same size as a pixel in the computer graphics world.

Computer graphics generally use a square pixel. Typical screen resolutions in the computer graphics world are 640 x 480, 800 x 600, 1024 x 768, etc., all of which are exactly a 4:3 ratio. Since the screen pixel aspect ratio matches the screen physical aspect ratio, each pixel is square. This means, for example, that a box that is 50 pixels wide and 50 pixels high will appear as a square with four equal-length sides.

Television systems operate with the same ratio video screens (4:3), but the ratio of the number of pixels to the number of lines is not 4:3. In the 525/60 world, a 720 x 486 image works out to a ratio of 4:2.7. In the 625/50 world, a 720 x 576 image works out to a ratio of 4:3.2.

When graphics are created on a computer graphics system with square pixels, and then transferred to a television system with non-square pixels, aspect ratio distortion can occur. This distortion causes the graphic to appear stretched or squashed in the vertical and/or horizontal direction.

A simple technique can be used to eliminate aspect ratio distortion. Instead of creating graphics at the television-pixel sizes, create the graphics at computer-pixel sizes. When you are finished, save the graphics (it is always recommended that you keep an original in case you need to alter the graphics at a later date), and then resize the graphics to the television-system size. The graphics appear distorted on the computer screen, but are correct when converted to the television video signal.

Any 4:3 ratio resolution can be used to create the graphics, regardless of whether you are working in the 525/60 world or the 625/50 world.

Creating the Logo on a Black Background

All area around the logo must be filled with a solid black background. The easiest way to achieve this is to start the creation process with a solid black image and then draw the logo. This process must be done with both the Fill and the Key graphics.

Using a higher resolution is always the better approach. You can work in 800 x 600, 1024 x 768, 1600 x 1200, or any other 4:3 ratio resolution. When saving a file for use with the Logo Utilities, resize the complete graphic to the “ideal” pixel resolutions listed on page 5.



Sizing and Positioning the Logo

The Logo Utilities always assume that the graphics files for the Fill and Key represent a full-screen view of the video screen. The VES-680 only stores full-screen logos.

The Logo Utilities allow you to create logos in a variety of sizes. The LGI-6801 is limited to the storage and playback of logos one-ninth in size. The maximum size logo can only occupy one-third of the horizontal and vertical dimensions of a full screen.

For consistency, the Logo Utilities will always capture the logo from the bottom right corner of the graphics file. Regardless of the size and location of the logo during the creation stage, the logo must be reduced in size and positioned within an imaginary one-ninth box in the bottom right corner.

Although the logo is captured in the bottom right corner, logos may be easily repositioned at any time after being stored on the LGI-6801 module. There is no positioning available with the VES-6801 module.

The Video and Key graphics must be located in identical positions in the graphics files, or the logo will not display properly. The logo may be positioned against the bottom or right edge without concern for safe title or safe action.

Creating Logo Graphics

To properly create the Logo graphics file, follow these steps:

1. Create full-screen graphics with solid black backgrounds for both the Fill and the Key in one of the recommended 4:3-ratio resolutions.Create the Logo graphic (and corresponding Key graphic, if necessary) in the blank black graphics mentioned above. Remember to make both the Fill and Key the same size to preserve alignment. For the LGI-6801, shrink the Logo graphic to one-third the horizontal dimension and one-third the vertical dimension of the full-screen graphic. Repeat for the Key graphic.

2. Position the shrunken Logo graphic into the full-screen graphic at the bottom right corner.

Repeat for the Key graphic. The full screen now contains the logo in the lower righthand corner of the screen.

3. Save this file, and use it and the corresponding Key to create the MGI file.



Using the Logo Graphics Conversion and Download UtilitiesWith the Logo Graphics Conversion and Download Utilities™, Logo graphics files must be loaded into the 6800 series module directly from a DOS- or Windows-based computer. Two versions of the utilities are available: LogoDOS operates in a DOS text mode, and LogoWIN operates in a Microsoft Windows [3.1/95/NT] environment. Both utilities offer the same functionality and support a wide range of graphics file formats.

Figure 1-2. Supported Graphics Formats

Running LogoDOSIf the logo has been created in an unsupported format such as video industry-specific formats GVG Paint (.TV) or Quantel Paintbox (.QTL), you must contact the software manufacturer for a utility to convert the graphic to one of the industry-standard formats listed above.

To start the LogoDOS program from the DOS command line:

1. Type LOGODOS at the C: prompt. The LogoDOS command line syntax is: <drive:<path\> LOGODOS<options>

Supported options are: COMx (where x is 1, 2, 3 or 4).

2. Type in the appropriate COM port in place of the x parameter.

The default COM port is COM1. Selecting COMO will disable communications, but still allow the utility to operate.

When the utility begins, communication is established with the 6800 series module. The program determines the logos currently stored in the system and displays the options:

• C (Create a new MGI file)

• S (Send the MGI file to the Logo Generator)

TIFF* JPEG PCX TGA DIB DCX

GIF BMP WMF PICT WPG XBM

KFX RLE LV CALS G3 G4

ATT CLP XWD IMG IFF SUN

ICA GX2 XPM ASCII CUT BRK

MAC PSD MSP PCD EPS ICO

*Capable of storing 10-bit files, but this resolution must be supported by the graphics application.



• I (Information on the MGI files)

• R (Retrieve an MGI file)

• D (Delete a logo)

These are explored in greater detail in the following sections.

Creating a New MGI FileThis option allows for the creation of MGI logo files that can be stored on the computer hard drive and downloaded to the 6800 series module as needed. To create an MGI logo file, select “C” at the LogoDOS main menu and respond to the prompts as they appear on the screen.

The LGI-6801 supports logos one-ninth in size static mode. The VES-6801 supports full-screen logos. Only these two selection types will be discussed.

The following information is required:

1. Size–For LGI-6801, select 9 for one-ninth screen.

For VES-6801, select 1 for full screen.

2. Video Standard– Select 2 for D1 525 (4:2:2 270 Mb/s component) or 3 for D1 625 (4:2:2 270 Mb/s component).

3. Resolution– Select 1 for 8-bit or 2 for 10-bit.

4. File Name (with extension) of the Video Fill graphic– If the file is not located in the same directory as the LogoDOS program, enter the drive, path and filename of the graphics file.

5. File Name (with extension) of the Key graphic—Drive and path must also be provided if the file is not located in the same directory as the LogoDOS program.

A logo may be created without the use of a separate linear Key file. The LogoDOS utility can perform a Self-Key using the Fill graphics file and a luminance slice level. When entering the linear Key filename, enter NUL, and you will be prompted for a slice level. Select the slice level by determining a luminance level higher than the background (black) level, but lower than any pixel in the logo itself. If unsure, select 10 IRE as a starting point, and adjust after looking at the Key signal created.



Sending an MGI File to Logo GeneratorAfter the MGI file has been created and saved, the logo may be downloaded to the 6800 series module by selecting S at the LogoDOS main menu. A list of available MGI files is displayed. At the command line, enter the file name of the Logo file to be downloaded.

Before sending a file to the 6800 series module, you must assign a unique logo number to the Logo file. A list of existing logos is displayed. If you select a number already assigned to a logo, the previously stored logo will be deleted. (You will be warned before the logo is deleted.)

A single logo one-ninth in size downloads in approximately 2 minutes. A full-screen logo downloads in approximately 12 minutes.

If the 6800 series module does not have enough available memory to store the logo successfully, the LogoDOS program displays the following error message:

CANNOT CREATE LOGON

ERROR - OUT OF MEMORY

For the VES-6801, the following message is displayed after download, with an indicator to show activity:

PROCESSING DATA

This activity lasts for approximately 4 minutes and cannot be aborted.

Additional LogoDOS Menu OptionsAdditional options are available at the LogoDOS main menu. They are as follows:

• Selecting I - INFO on MGI files lists all files with the .mgi extension in the current directory. Each file listed will include the logo name, logo number, size of the logo, number of frames, and amount of memory used.

• Selecting R - RETRIEVE MGI file moves the selected logo from the LGI-6801 module to the current directory. Retrieval is not possible from the VES-6801 module.

• Selecting D - DELETE a Logo permanently removes the logo and the .MGI file from the 6800 series module. Deleted logos cannot be recovered.

For the VES-6801, the Key signal is not used. If the MGI file is intended for use with only the VES-6801, then select the Self-Key option. If the MGI file will be used in other LogoMotion products, then appropriate Key graphics or self-Key setting should be selected.

Slide DownloadThe standard of operation (525/60 or 625/50) and the slide resolution (8-bit or 10-bit) are set by the downloaded slide. The module can only operate in one resolution and one standard at a time.

For the VES-6801 single-channel module, this means that two 8-bit slides can be stored with different standards, and when played back, the output will follow the standard of the selected slide. In 10-bit resolution, only one slide can be stored, and dual-standard is not an option.

For VES-6801-2 dual-channel modules, both channels must be in the same standard and resolution.

Creating, Recording and Downloading SlidesCustomer-designed logos (slides) may be loaded into the VES-6801 via the LogoMotion Graphics Conversion and Download Utility. This Utility loads the custom-created files from a computer via a serial port. The VES-6801 module creates and embeds the EAV, SAV, and EDH data packets after the graphic is loaded.

Terminology

The download operation uses either LogoDOS or LogoWIN. These are generic applications that refer to “logo”, which is synonymous with “slide.” If there are two outputs available, they are as follows:

Slides can only be played back at the standard for which they were created. If the external reference does not match the slide standard, the output will not be genlocked. If slides of different standards are stored, the module standard is set by Channel A.Playing slides of different standards on Channel B will result in erroneous data.

Refer to Chapter 1 of this manual for more information.

In 8-bit mode Slides 1 and 2 are visible only to Output A.Slides 3 and 4 are visible only to Output B.

In 10-bit mode Slide 1 is visible only to Output A.Slide 2 is visible only to Output B.

A slide must be loaded before valid data can be output. The VES-6801 uses data embedded in the file to generate valid timing information (SAV/EAV). The serial waveform may appear normal before the slide download, but it is not valid until download is complete. During download, the serial outputs are muted.

DSK-6801/3 Downstream Serial Keyer

OverviewThe Downstream Serial Keyers (DSK) 6801 and 6803 are designed to meet the need for the insertion of high-quality key signals in today’s busy production and post production facilities. The production market is demanding increasing numbers of key insertions into program video, and the DSK-6801 and DSK-6803 are important supplements to the limited keying capability of current production switchers.

The DSK-6801/3 modules are standalone serial digital keyers with a full complement of features, many of which are found on high-end production switchers. Some of the features offered by both the DSK-6801 and the DSK-6803 include:

• Support of a 270 Mb/s 525/625 program and Fill/Key input signals. All inputs auto time, with approximately ± one-half line timing buffers.

• Error Detection Handling (EDH) on inputs and EDH insertion on the program output.

• A 10-bit program path, coupled to 12-bit internal keyers, to provide optimum quality.

• Passing of all ancillary data present in the program path. (Any embedded audio is also passed, uninterrupted.)

• Ability to use the Keyer in A/B Background Transition (Roll) mode, without keys. In this mode, the Fill path is used as a second background (B), to be wiped or faded from the program channel (A)DSK-6801 Keyer features.



Chapter 4: DSK-6801/3 Downstream Serial Keyer Overview

DSK-6801 Keyer FeaturesThe DSK-6801 Downstream Serial Keyer offers the following features:

• Luminance (Self-Key), or linear keying using the Key signal

• Mix mode keying

• Key masking

• Adjustable transparency, gain, and offset

• Adjustable fade rates

• Fade-to-black control

• GPI control

• XY interface for connection to a remote panel

• EDH checking of program input

• EDH CRC generation on program output

• Optional compact remote control

Chapter 4: DSK-6801/3 Downstream Serial Keyer Installing and Setup

Installing and Setup

System Setup ConsiderationsThe items in this section should be read and implemented at the time of installation.

Standard Selection

The Keyer is equipped to:

• Force a given standard (either 525 or 625 lines).

• Allow the module to auto detect the incoming standard.

In sensitive applications the standard should be set to 525 or to 625. Make sure the appropriate line rate is always selected.

Lock Source

There are two modes of locking the Keyer to the given sources:

1. Lock to the incoming PGM input.

The operator can only adjust horizontal timing toward minimum length or toward one full line length in delay.

2. Lock to an external analog reference.

In this mode, both horizontal and vertical timing adjustments are available. Adjusting the Keyer timing for proper Keyer operation compensates for the relative difference between reference V and program V.


Installing and Setup Chapter 4: DSK-6801/3 Downstream Serial Keyer

Keyer Timing

Keyer timing is derived from the lock source. The lock source can be either the PGM input or the external analog reference.

Using the PGM input as the lock source, Keyer timing operates with the Keyer set to one half line delay, with the Fill and Key inputs autotimed from within ± one half line. The Fill and Key inputs are automatically adjusted to fit within the timing window. This selection allows the timing to be adjusted as follows:

• Minimum timing can be adjusted by reducing the Horizontal phase towards zero. Make sure after adjustment that the Fill and Key inputs still fall within the timing window. See “Position 5: SW2 System Horizontal Timing” on page 75.

• Using the external analog reference as the lock source, keyer timing operates in much the same way as when locked to PGM input. The main difference is that both the horizontal and vertical timing can be adjusted. See “Position 5: SW3 System Vertical Timing” on page 75.

• In the external analog Reference mode, the delay of the video signal may be a concern. If so, the delay can be adjusted toward a full line.

• If Key and Fill fall beyond the timing window, the keying operation is not usually allowed. To override this function, set the Sync Detection to Off. See “Position 7: SW3 Sync Detection” on page 77.

To aid the timing alignment, the operator should use the auto timing function to phase the internal timing to the program Key and Fill serial videos. The timing is varied for both horizontal and vertical, so all three inputs (Program, Key, and Fill) are within the one-line window. If the input signals are spread over more than one line and alignment is not possible, an error is displayed and the sources must be corrected externally. See “DSK-CP1/2 Downstream Serial Keyer Control Panel” table on page 91.

Multiple Keyer Control/Group ID

The DSK-CPx uses the Group ID function to control multiple Keyers. Each Keyer is set up with an individual address (Keyer ID) and can then be configured to work using Group IDs, controlled by the DSK-CPx.

You may need to set different Group IDs, depending on how the network layout and module control is handled. See “DSK-CP1/2 Downstream Serial Keyer Control Panel” on page 91.

An error is displayed if Key or Fill are beyond the timing range. See “Error LEDs” table on page 53.

Error LEDs

The Error LED illuminates an error condition and, combined with the MOD1-4 LED indicators, produces an error status pattern (or error code). This produces a definable status, which prompts the operator to locate and correct error conditions.

BNC Selection, Jumper Setup, and Switch SetupBNC selection, jumpers, and switches are set at the time of installation and adjusted as necessary. The following describes the BNC selection options as well as jumper and switch setting options for both the DSK-6801 and the DSK-6803.

BNC Selection

To make BNC setup easier, the connector numbers shown on the rear modules are also used as reference numbers in tables and figures. See and “DSK-6803 Rear Module Connectors” table on page 50 for examples of how the connector numbers are used.

External Sync Reference Termination

Keyer Module ControlsThe DSK-6801/3 modules have the following control mechanisms:

• Front edge control

• GPI control

• DSK CP control

Adjusted parameters are only stored after 5 seconds of inactivity.

Front Edge Control

Front edge control is accomplished using Hex Switch SW1 and Toggle Switch SW2 to select one of three possible Shift States (Shift State 0, 1, and 2). Each Shift State provides access for up to 15 different control/setup options. Upon powering up, the module is automatically set to Shift State 0. Shift State 1 and 2 are accessed as follows:

1. Move SW1 to Position 0.

2. Toggle SW2 up or down to achieve the desired Shift State.

The Shift State LEDs on the front edge of the module indicate the current Shift State setting. For example, when Shift 1 LED is illuminated, the module is in Shift State 1. Shift State 0 has no LED indicator. See Figure 4-5 on page 52 for more information.

J6 Open

J7 Right

Change of external sync level from 300 mV to 4 V is available through the main hex switch. See “Front Edge Control” table on page 57 for more information.

J8 Right, for 75 Ω

J8 Left, or open, for HIZ

In Hex Position 0, when a Shift State is inactive for approximately 30 seconds, the module is automatically timed out and reset to Shift State 0.



The following tables are provided to illustrate the functionality of the Shift States. Each Shift State table shows SW1 positions with the SW2 and SW3 corresponding actions.

In the following tables, non-shaded sections apply to DSK-6801 and DSK-6803. Shaded sections are DSK-6803 extensions only.

Settings for Shift State 0: General FunctionsThis section gives a more complete description of the Keyer Module controls for Shift State 0. It is organized by Hex Switch Positions (Position 1, 2, etc.). Shift Hex Position 0 is not included in the following listing since its function never changes.

Position 1: SW2 Key Offset

Key Offset (incremental/decremental) varies between 0 and 1024 with the standard being 64.

• Subtract the Offset (or Clip) value from the Key Input.

• Push SW2 up to increase the Key Offset.

• Push SW2 down to decrease the Key Offset.

• Set Key Offset to 0 with a gain of 16 to display Key full on screen with no program.

Position 2: SW2 Key Gain

Key Gain varies between 0.5 and 64 times.

• Multiply the Gain value by the Key Input and combine with the Offset to get the actual Key.

• Push SW2 up to increase the rate or down to decrease it.

• Push the SW2 up to activate the Fade Key.

• Push the SW2 down to deactivate the Fade Key.

The active function of the Fade Key is to fade the keyed video onto the PGM/Program output.

Deactivation causes the keyed video to fade Off.

If a Fade is already in progress, a Fade in the same direction has no effect; a Fade in the opposite direction will take effect.

When FTB is active (black is shown on PGM OUT), the Key Transition rate is ignored. Any Key Transitions performed while the output is black act as a Key Cut. Then the Fill may or may not be keyed depending on the Fade Key setting.

Position F: SW3 Cut Key

The Cut Key transitions the Key On or Off instantly. When in black (FTB is active), the Cut Key switch has the same function as the Fade Key switch and operates in the same manner.

Settings for Shift State 2: ConfigurationThis section gives a more complete description of the Keyer Module controls for Shift State 2. It is organized by Hex Switch Positions (Position 1, 2, etc.). Shift Hex Position 0 is not included in the following listing since its function never changes.

Position 1: SW2 GPI 1 Action

The General Purpose Interface 1 (GPI 1) Action state allows the GPI Input behavior to be configured to Key Fade or Key Cut and FTB Fade or FTB Cut.

For the action of each of these settings and more details, see “GPI Control” on page 79.

Position 1: SW3 GPI 1 Type

GPI 1 Type can be configured as follows:

• Inputs: Rising Edge/Falling Edge/Active High /Active Low/Off.

• Tally: Tally High/Tally Low.

• GPI control settings are cycled through by toggling SW3 Up or Down.

• A GPI Input will perform the assigned action when the trigger is detected.

• A GPI Tally sets its output level to the assigned Tally Active Level when its trigger condition is in effect, and sets its output to the opposite level when the condition is not found.

• A Tally that acts on Key On will be active whenever the Key is even slightly On Air (similar to the behavior of the On AIR LED). This is the normal use for a Tally.

• A GPI can be assigned as an output to give a similar indication for Fade to Black.

• The Error Triggers are presented such that the Tally Output can indicate the error or feed a GPI Input (of another Keyer), which may be used to override the erroneous signal.



GPI 1 Type LED indicators are described in the following table:

The GPI 1 Type allows the GPI 1 to become active by a (configurable) detected level or edge.

The Active High setting allows the GPI to become active upon detection of a high level.

The Active Low setting allows the GPI to become active upon detection of a low level.

The GPI Tally can be configured as Tally High or Tally Low. The GPI state is toggled by the rising or falling edge of the input, as is typical behavior from a normally open, momentary closure push button.

The Off setting causes the GPI to be ignored and the LEDs to flash. Possible settings can be cycled through by toggling SW3 up or down.

Position 2: SW2 GPI 2 Action

GPI 2 Action and GPI 2 Type function in the same manner as GPI 1 Type and Action.

GPI 2 must be enabled through jumpers in order for these settings to take effect. See “BNC Selection, Jumper Setup, and Switch Setup” on page 53 for settings.

Position 4: SW2 GPI 4 Action & SW3 GPI 4 Type


The next four positions (Positions 5 and 6) work in association with each other to adjust the Internal Timing to the three Input serial signals: Program, Fill, and Key. Normally, modifying the Vertical and Field Timing can cause unpredictable results and is only adjusted to bring an External Reference in line with the Program, Fill, and Key Input serial signals. All three Inputs must be within the one line window for the system to function properly.

Position 5: SW2 System Horizontal Timing

System Horizontal Timing is used to manually adjust the horizontal timing, to reduce the time length of the module (delay) towards zero, or to increase it towards one line.

Use SW2 to toggle this function.

Position 5: SW3 System Vertical Timing

System Vertical Timing is used to manually adjust the vertical timing. This is normally handled by the Auto Timing function and only needs to be manually adjusted to bring an External Reference in line with the main Program, Fill, and Key.




Position 6: SW2 System Field Timing

System Field Timing is used in association with the previously mentioned Timing functions: Position 5 SW2 and SW3. This function allows manual adjustments to the System Field Timing, and is used to bring an External Reference in line with the main Program, Fill, and Key inputs.


Position 6: SW3 Auto System Timing

Auto System Timing works in association with the other System Timing functions. The Auto System Timing function brings all three Input serial signals within the one-line window and centers the Horizontal Timing setting. If necessary, the Horizontal Timing can then be manually adjusted. See “Position 5: SW2 System Horizontal Timing” on page 64 for more information. Ensure all inputs still fall within the Timing window.


Three LEDs are used to display the following information:

The Error LED also illuminates if any of the three Input signals are out of time. If there are any errors after Auto Timing and the module cannot compensate for the differences in signal timing, the Error LED is illuminated, and the timing must be corrected externally (as documented previously in Positions 5 and 6).

Position 7: SW2 Set Standard

Set Standard (525/Auto/625) allows the video standard to be configured for 525-line, 625-line, or Automatic Detection from the PGM Input. The possible settings can be cycled through by toggling SW2 Up or Down.

MOD1 Illuminates when the Program signal is out of time.

MOD2 Illuminates when the Fill signal is out of time.

MOD3 Illuminates when the Key signal is out of time.



Position 7: SW3 Sync Detection

If Sync Detection On/Off default setting is enabled (On), when the module detects a Sync Error, the error codes are displayed and the Key is cut.

Set Sync Detection Off to disable the module cutting the Key. This also allows the input to fall outside the timing window. Error codes are still displayed, and keying is allowed.

Use SW3 to toggle Sync Detection On/Off.

LED indication:

Position 8: SW2 External Sync Type

The External Sync Type control selects the type of sync, either composite 300 mV or 4 V.

Use SW2 to toggle Ext Sync Type selections.

LED indicators:

Position 8: SW3 External/Program Sync Select

External/Program Sync Select is where the reference for Internal Timing is taken, from either External Sync or the Main Serial Program feed.

Use SW3 to toggle Ext/Program Sync selections.

LED indication:

Select Ext Sync to lock to External Reference Sync. For proper operation, both Lock and External Sync LEDs should be on.

MOD4 On

Position 9: SW2 Mask Reset

Mask Reset is used to re-position the Mask. Use the left switch (SW2) to toggle Up and Down and to move the Mask into view.

For Keyer ID Upper Address value, see “Keyer Module Controls” table on page 57.

Position B: SW2

This position is used to set the Keyer ID Address value. See “Keyer Module Controls” on page 57.

Position C: SW2

This position is used to set the Keyer ID Lower Address value.

Position F: SW2 Recall Factory Default Key Settings

The Recall Factory Default Key Settings function resets the Keyer with the factory set defaults. This means that a DSK-CPx controlling a DSK-6801/3 may lose contact with the Keyer since its Keyer ID has been reset (when the factory default feature was activated). The Keyer ID will have to be set to the old Keyer ID value, or the DSK-CPx can be set to control the DSK-6801/3 at its factory default Keyer ID value.


Position A: SW2 and SW3 are not used.

Position D: SW2 and SW3 are not used.Position E: SW2 and SW3 are not used.



Position F: SW3 Recall Factory Default System Settings

The Recall Factory Default System Settings function resets the Keyer with the default system settings.

GPI ControlA second control method is available using GPI Control, GPI, or GPI 2. The GPIs can be programmed to be edge triggered or level-triggered, and can be assigned to the functions shown in the following table.

DSK-CP1/2 Control

The DSK-CP1/2 offers a complete control panel with dedicated buttons for important functions. The control panel uses the XY control port to connect to the DSK-6801/3 modules. See Figure A-1: DSK-CPx Layout on page 151 for further information.

Parameter Range List and Key DescriptionsThis section gives the parameter range list and provides Key descriptions as follows:

External Key

The External Key is used for the keying operation.

Self Key

In Self-Key mode, the Key Input is ignored. Self Key is obtained from the luminance portion of the Fill. Normally, Gain and Offset are applied to attain more desirable effects.

Chroma Key

In Chroma Key, as in Self Key, the Key Input is ignored. The Key is obtained from the chrominance (color) portion of the Fill. Gain and Offset can be applied for more desirable effects.

Transparency

Transparency is a post Gain setting. After Clip, Offset, and Key Gain have been applied to the Key signal, the effect makes the keyed appearance look transparent. One hundred percent (100%) transparency appears the most solid, while zero percent (0%) is invisible.

Gain L

Gain is applied to the Key signal. This effect is used to amplify the Key signal towards white. The edges of the Key are modified to make them appear sharper, and when used in conjunction with Clip/Offset, can change the size of the Key cutting hole.

Normal/Self Key Setting Range Resolution

Transparency (Up/Down) 0 - 100% 1

Clip/Offset (Up/Down) 0 - 1024 1

Gain (Up/Down) 0.5 - 64 0.1



Clip/Offset

The terms “Clip” and “Offset” are interchangeable. This setting is simply a negative offset applied to the Key (before Gain is applied to the Key signal). The nominal Offset is 64 and can go to 1024, black to full white level.

This control is usually used in conjunction with Gain. For example, taking a Gain of 2 and an Offset of 64 makes the module use the bottom half of the Key signal for keying. If the Offset is set to 512, the module uses the top portion of the Key signal for keying.

If you view the Key edge as triangular ramps, use the bottom portion of the Key signal to widen the key, and use the top portion to narrow the key. The Gain can be increased to 64 times, so when used in conjunction with Offset, the keying action can use any 1/64th slice of the input Key wave form. See “Gain and Offset Combinations” on page 82.



Figure 4-9. Gain and Offset Combinations



Chroma Key

The Chroma Key (when selected as source) provides a Key derived from the color components of the Fill. The selected color is extracted and inverted to produce the Key signal. The following table shows the Chroma Key range and resolution settings.

Chroma Key Range Resolution

Hue (Up/Down) 0 - 359 1

Saturation (Up/Down) 0 - 1024 1

Discrimination (Up/Down) 0 - 1024 1



Chroma Hue

Chroma Hue is the amount of color in degrees (0 to 359) used as a color Key source. The various colors are indicated around the following diagram from 0 to 359 degrees.

Figure 4-10. Chroma Hue Color Range

Chroma Saturation

The Chroma Saturation control allows the Keyer to reject low saturated signals from being used as part of the Key signal. The degree of saturation is represented by the length of the color vector. This allows the operator no Key on low saturation to improve keying quality. The control acts like a level control in that, as the level moves up the vector, the unsaturated colors are rejected.

Chroma Discrimination

Chroma Discrimination defines the range of color available to be used to generate the Key signal. Ranges are from 1 to 180 degrees of the color spectrum. See Figure 4-10 “Chroma Hue Color Range” on page 84.

Chroma Luminance


Key Modifiers

There are three Key modifiers as follows:

• Key Invert has the effect of displaying the Fill on the low portion of the Key. It can be turned On or Off.

Normally, Fill is displayed on the high portion of the Key.

• Key Mask allows the Key signal to be cropped to display more of the background. It can be turned On or Off.

• Key Force uses the Mask to force an area of the Fill to correct holes in the Key signal. It can be turned On or Off.



Setting Key Mask

Crop the screen display to any size height and width by setting the Key Mask. See the following table for Mask range and resolution information.

Transition Controls

Transition Controls consist of setting the Transition Rate, setting the Transition Type (Fade or Wipe), and applying the Cut Key, Cut to Black, or Auto Trans.

The Fade to Black and Key Fade are mutually exclusive. The priority of the Fade is dependent on which is started first.



Video ProcessingThe Program, Fill, and processed Key signals are keyed via the PGM Mix mixer. These signals are passed to the PGM Fade mixer, which does the Key Fade and Fade to Black. The main Program Input (FILL) and keyed program (KPGM) each enter the FPGA for switching and retiming. The Preview Out (PRVOUT) is switched to the appropriate next event and then passed to the parallel of the serial driver and to the external outputs.

The FPGA also provides a color matte output to the PGM Fade, generating black for Fade to Black operations. The matte output is switched to the main program during blanking to ensure correct video passage.

The PGM Fade mixer passes its output for EDH re-insertion and then for serial paralleled conversion and cable driving.

Board ControlBoard control is accomplished by several methods as described below:

• RS232, using U34, which is jumper-selectable to the BNCs, using J4, J6 and J7.

• Model edge control via Hex Switch SW1 and Toggle Switches SW2 and SW3.

• The GPI input control is jumper-selectable to the BNCs, using J5, J6 and J7.

• Board status information is provided by means of the LEDs, D1 through D16, which are along the front edge of the PCB.

DSK-CP1/2 DownstreamSerial Keyer Control Panel

OverviewThe Downstream Serial Keyer Control Panel is designed to control a system of DSK-6801 and DSK-6803 Keyer Modules. There are currently two DSK Control Panels available, the DSK-CP1 and the DSK-CP2. The only difference between the two is that the DSK-CP2 does not have a Fader Handle.

The designation DSK-CPx is used in this manual where the information is applicable to both control panels; otherwise, the appropriate number is used. See Figure 5-1 on page 91 and Figure 5-15 on page 132.

Figure 5-1. DSK-CP1 Control Panel


Chapter 5: DSK-CP1/2 Downstream Serial Keyer Control Panel Overview

Figure 5-2. DSK-CP2 Control Panel

The DSK-CPx can be used in post and live production environments, providing the ability to change Keyer settings on individual or multiple Keyer Modules. There are dedicated Transition buttons, Setup buttons, and programmable Soft buttons, which enable the operator to access Keyer settings quickly and easily. Keyer settings such as Key Offset, Key Gain, or Key Transparency are changed by selecting the Keyer Setup menu and adjusting Keyer settings with the Control knobs. See “Dedicated Transition Buttons” on page 96 for more information.

The DSK-CPx can be customized by using the programmable Soft buttons. These buttons can be set to modify specific properties on a Keyer (or group) at the touch of the button or they can be set to perform a variety of other functions. See “Programmable Soft Buttons” on page 98 for more information.

The LCD screen contains four lines of display and has adjustable contrast and backlight settings. The LCD screen displays menus, Keyer information, and panel/system settings. Upon power up, the screen displays the Leitch company name and version level of the firmware installed.

There are a number of menus displayed on the LCD screen. Each menu contains specific properties of Keyer settings or panel/system settings. On any menu (which allows adjustments to keyer settings), the name of the currently controlled Keyer (or group) is displayed on the LCD screen, a valuable feature which contributes to the ability of a single DSK-CPx to control multiple Keyers. See “LCD” on page 100 for more information.

Key Invert


Overview Chapter 5: DSK-CP1/2 Downstream Serial Keyer Control Panel

There are four white cursor buttons on the control panel, used for up, down, left and right movement. Press the Up or Down cursor buttons to display the next menu in sequence (see Figure 5-11 “Menu Map System” on page 104). Press the Left or Right cursor buttons to move the shaded (highlighted) bar between modifiable property fields.

The DSK-CPx controls the Keyer Modules via the Leitch XY Serial Bus. When the DSK-6801/3 Keyer Modules are set up as groups, any DSKCPx panel can be configured to control that group or different groups of modules.

Figure 5-3 on page 93 shows an example of how one control panel can be used to control several Keyers. It illustrates a DSK-CPx connected to Keyer Modules (set in a frame) using the Leitch XY Bus connectors.

Dedicated Transition ButtonsThe functions of the dedicated Transition buttons are listed below:

• The Cut button cuts the logo immediately On or Off the Air.

• The Wipe button, when pressed, sets the key transition type to Wipe; the Mix LED is extinguished and the Wipe LED is illuminated. The next transition will be a Wipe and results are dependent on the Wipe pattern set.

• The Mix button, when pressed, fades the logo On or Off the Air. The Wipe and Mix buttons set the type of transition. Only one transition type may be selected at a time. When the Mix button is pressed, the Mix LED illuminates, and the Wipe LED is extinguished.

• The Auto Trans function is dependent upon the Auto Trans Rate set on the Trans Setup menu and the Key Transition Type selected. If you select Wipe (On or Off the Air), the control panel will “wipe” the logo when the Auto Trans button is pressed. The Auto Trans LED is always illuminated during Fade/Mix or Wipe transitions. During a Fade to Black or Auto Transition the associated LEDs are illuminated.

• The Fade to Black button, when pressed, fades the DSK-6801/3 program output to or from black. When the Fade to Black button is pressed, the Fade to Black LED is illuminated during the Fade to Black operation.

• The Fade to Black LED blinks when the program output is at full black.

The Fade to Black operation cannot be performed while the Fader Handle is being moved (up or down), or immediately after the Auto Trans button is pressed. The Fade to Black function occurs after the Fader Handle is returned to a stationary position or Auto Trans is complete.



Dedicated Setup Buttons

The five dedicated Setup buttons are pre-programmed to display a specific control menu when pressed. Each controls the five major Setup menus for the control panel.

Figure 5-5. Setup Buttons and Corresponding Control Menus

The Setup buttons are as follows:

• The Keyer Setup button displays the Keyer Setup 1 menu which contains properties for modifying Offset, Gain, and Transparency.

• The Trans Setup button displays the Trans Setup menu which contains the properties for modifying Auto Trans and Fade to Black rates.

• The Panel Setup button displays the Panel Setup1 saving and recall Keyer setups.

• The System Setup button displays the System Setup menu and contains properties for setting PrgPrv, Key, GlbCmd, and Sysmenu. This menu also provides access to other menus.

• The Keyer Grp/ID (Keyer ID and Group ID) button displays the Keyer/Grp ID menu. This menu displays the name of the Keyer, its ID number, the Group it is assigned to, and the mode of operation.

Programmable Soft ButtonsThe DSK-CPx has five programmable buttons. Each can be programmed as one of three types: Keyer type, Menu type, or Menu Property Type.

Figure 5-6. Programmable Soft Buttons

Keyer Type

Up to two Keyers can be assigned to a Soft button by Keyer Name when the property type is set to Keyer: One Keyer can be set to Program and the other to Preview. The Key1/PRG and Key2/PRV properties can have a single Keyer assigned to each simultaneously, and will then react to the same Soft button (when pressed.) In Multiple Mode (Program/Preview Modes = Off), both Keyers will react in the same way to commands. If the Program/Preview Mode is On, the Keyers act as program and preview Keyers.

• The Menu Type program displays a specific menu.

• The Menu Property Type program is a specific property on a menu designated to a Soft button. If it is a toggled action property, press the Soft button to toggle the selected function On or Off.

Although this is not recommended for normal operation, the same Keyer namecan be assigned to both Key1/PRG and Key2/PRV properties.



There are two methods for programming a Soft button to select a menu or menu property:

1. Display the menu that you want to program to a particular Soft button, and hold the button down until the following message appears on the display screen:

soft button programmed

That button is now programmed to display the selected menu. On menus where there are three or fewer modifiable properties, press the button to simply display the menu. To program a Soft button to select a property on a menu with three or less properties, use method 2.

2. The Soft Button menu is used to program Soft buttons. Scroll to this menu using the white cursor button. Next, set the property type to Menu. Then, select the desired menu and the desired property. Soft button actions/functions are performed at the release of the button.

For complete programming information, see “Programmable Soft Buttons” on page 98.

Cursor Buttons

The Up and Down white cursor buttons allow you to scroll through the menu list, displaying each menu in turn. The Left and Right cursor buttons move through a selected menu’s modifiable properties.

Once the user has selected a menu using the Up and Down cursor buttons, the Left and Right cursor buttons are used to scroll through the menu property’s label fields. When the property’s label field is highlighted by the cursor, the modifiable properties field (value) is underlined and can be changed using the Control knobs. For a graphic and more information, see “Using the White Cursor Buttons” on page 109.

Control Knobs

The DSK-CPx has three Control knobs that are used to adjust the settings displayed on the LCD screen. The Control knobs are described in further detail in the menu section. See “Using the Control Knobs” on page 109.



LCD

The LCD screen displays up to four, 2-character lines of information, and is used to display the DSK-CPx menus. On power up, the LCD shows the Leitch company name and version level of the firmware installed. The display screen has two operator adjustable properties: Contrast and Backlight. See Figure 5-7 on page 100.

Figure 5-7. DSK-CPx Menu Example as Displayed on the LCD Screen



LEDs

The DSK-CPx contains several types of LEDs: Key On, Fader Position Up and Down, and button LEDs.

Key On LED: One of the most important and unique LEDs is labeled (in the shape of the words) Key On LED. This LED indicates that a logo is being keyed on the program output of a Keyer Module. The Key On LED is illuminated when the current Keyer or group of Keyers, being controlled by the DSK-CPx, has a logo on the program output or On Air. The Key On LED always indicates an On Air condition.

Figure 5-8. Key on LED Indicating On Air Condition

The arrow-shaped LEDs are only installed on the DSK-CP1 model and indicate the up and down movement of the Fader Handle. When the Fader Handle leaves the bottom position, the Up arrow LED is illuminated, and remains so until the Fader Handle returns to one of the end points. Similarly, when the handle leaves the top position the Down arrow LED illuminates.

The Up and Down arrow LEDs are not illuminated when the Fader Handle is at rest on an end point.

When the Fader Handle is in the process of being moved or the Auto Trans button is pressed, the Fade to Black button is not active (available).



Figure 5-9. Fader Handle Arrow LEDs

The buttons on the control panel have an associated LED that illuminates when the button (or associated function) is activated.

For example, the Auto Trans button LED illuminates when the Auto Trans button is pressed and the fading function is taking place. Once the Auto Trans operation is finished, the Auto Trans LED extinguishes.

When a Soft programmed button toggles a menu parameter, the associated button LED is illuminated if the function assigned to it is On. For example, if a Soft button is assigned to the function of Key Invert, the Key Invert function is toggled (On or Off) when the button is pressed. When it is On, the button LED is illuminated, and when it is Off, the button LED is extinguished.



Exceptions are:

• The FTB button LED flashes when the currently controlled Keyer (or group of Keyers) is faded to black.

• Mix and Wipe LEDs cannot be on at the same time; therefore, only the appropriate LED is illuminated to reflect the transition effect selected.

• The dedicated Setup button LEDs are not configured to illuminate in this release of the DSK-CPx.

Keyer Setup1

The Keyer Setup1 menu contains the Offset, Gain and Trans (Transparency) options. Each of these properties affects how the Key will appear.

• Ofst/Sat (Offset/Saturation) is subtracted from the Key input. Settings range from 0 to 1024.

• Gain is multiplied by the Key Input to get the actual Key. The settings for Gain range from 0.5 to 64. Gain is used during Chroma Key setup. Use the dedicated button to select this menu and the Chroma Key menu. The Gain should initially be set to 10 before making Chroma adjustments.

• Trans varies between 0 and 100%. When the Transparency is at 100%, the selected Gain and Offset are fully applied. When Transparency is zero (0%), nothing will be keyed onto the output.

Chroma is available on the DSK-6803 only.



Keyer Setup2

The Keyer Setup2 menu is available (from the Keyer Setup1 menu) by pressing the Down cursor button. This menu contains properties for modifying KeyInv (KeyInvert) and Source, and allows you to select the source for the Key.

• KeyInv is a toggle type function. Use the Control knob beneath it to change the setting to On or Off. When this function is On, the KeyInv LED illuminates. When the function is toggled Off, the LED extinguishes.

• KeyInv takes an inverted version of the Key Input to perform the keying. The effect of this is the same as subtracting the Key from the maximum white value (i.e. black where the input is white and vice versa).

• Source indicates whether the Key signal should be taken from the Ext (External) Key Input or extracted from the Fill Input (Luminance/Self).

Trans Setup

FTB (Fade to Black) indicates the rate, or number of frames, a Fade to Black will take. If the FTB rate is set to zero, the Fade will go straight to black and will be indistinguishable from a Cut to Black.

AutoTrans indicates the rate, or number of frames, a Fade and/or Wipe will take. Setting the rate to zero will make sure the Fade or Wipe resembles a Cut. Settings are 0 to 100 for both FTB and AutoTrans.

Mask Setup1

The Mask Setup1 menu contains several options for controlling the box Mask.

• Mask toggles the Mask On or Off. The Key Mask overrides the Key signal outside the area where it is placed.

• MskInv switches the Mask function so that it overrides the Key signal inside the area where it is placed.

• FrcKey sets the Key Mask to Force mode which is indicated by the On status of the Mask. The result of initiating the Force mode is that the masked area displays the Key signal as fully on.

Mask Setup2

There are four controls on this menu: Top, Bottom, Right, and Left. Each defines the boundaries of the Mask in their respective directions.

Settings are:

• Top and Bottom: 0-512

When the GPI is triggered and performs the actions listed above, they perform as indicated by the name. For example, the FTB (Fade to Black) selection causes an FTB to be performed on the input section of the GPI specified.

When the Type property is set to Output, the GPI Setup menu is displayed as shown below:

To set the output Trigger:

The Trigger property specifies the condition upon which the DSK-CPx will activate the GPI (using the Trigger option selected).

1. Select the GPI # to be set.

2. Move to the Type property and set to Output.

3. Move to the Trigger property and set as desired. The setting of this property determines the state upon which the GPI Output is triggered. Valid selections are: Key On (the Key/logo is “in” the program output), Black On (the program output has been set to black), Program Error (used to detect a program lock error), or Any Error (any error condition that would cause the Error LED to illuminate will also trigger the GPI with this setting).

4. Move to the Active property and select Active Low or Active High. When triggered, this property directs the output to be held at a low or High setting.

Keyer Grp/ID

This menu allows you to select one or more Keyers by Name or by Device Address (Group ID + Keyer ID). The Keyer Grp/ID menu contains the following fields:

• Name displays Keyer or Group names. When a Keyer is selected by name, all parameters on the menu change to reflect the selected Keyer settings. Selecting by name allows you to control a single Keyer or a group of Keyers, depending on what type of name is selected. Names can be single (Keyer) names, or group names and are only available for selection if the name has been added to the control panel Name List.

• Group displays the Group ID number. To select a Keyer by IDs, set the Group property to the Group ID number of the desired Keyer and then set the Keyer property to the Keyer ID number. The Name and Mode properties change to reflect the Keyer selected.

• Mode displays the mode of operation. Selections are Single mode or Group mode. To control all the Keyers within a group, set the mode parameter to Group. To control a single Keyer, set the Mode to Single.

• Keyer displays the Keyer ID number. To select a Keyer by ID, set to the desired Keyer’s number. Set the Group property to the Group ID number and the Name and Mode properties change to reflect the selected Keyer’s settings.

Keyer Grp/ID

Name: Keyer Mode: Group

Group: 4 Keyer: 123



System Setup

The System Setup menu is one of the most important menus on the control panel. From this menu, you can set Pgm/Prv (Program/Preview) mode and GlbCmd (Global Keyer Setting Command) mode. You can also deny access to the other system menus. Use the Sysmenu property to set access to system menus On or Off.

The Pgm/Prv (Program/Preview) property can be set to On or Off. On sets the control panel to PgmPrv mode. In this mode, the program Keyer displays program output, and the preview Keyer displays the results of the next event. The preview output will never fade to black as it is more rewarding to view the program output after it fades from black.

Keyer names must be programmed to the Soft buttons so they can be selected for Pgm/Prv mode.

When more than one Soft button has been programmed to select Keyers, you can then select multiple program/preview pairs of Keyers. The selected Keyers are controlled simultaneously.

1. To select a Keyer, press the Soft button once, at which point the LED on the button illuminates.

2. Press the button a second time to deselect the Keyer, and to extinguish the LED.

When the control panel has multiple Keyers selected (via the Soft buttons) or is in Pgm/Prv (mode, do not use the Keyer Grp/ID menu to select a Keyer/Group. This will disable the Pgm/Prv mode and deselect the Keyers.

• The Key can be set to Mix or Add. Mix mode is the default setting. Add mode takes the Key signal and cuts a hole into the program input. When the Fill signal is added, it results in the final program output.

The GlbCmd can be set to On or Off. The default setting is Off.

• With GlbCmd set to Off, only transition control messages (Cut, Wipe, FTB, etc.) are sent to the selected Keyers where one of the following is true:

System Setup

Pgm/Prv: Off GlbCmd: Off

Key: MIX Sysmenu: On

Soft button actions/functions take effect when the button is released.



• The mode is set to Group.

• More than one Keyer is selected with the Soft buttons.

• The Keyer currently selected is assigned a group name.

The control panel can send all commands to a Keyer (when GlbCmd is Off) only when controlling a single Keyer and one of the following is true:

• The mode is set to Single.

• Only a single Keyer is selected using a Soft button

• If the operator attempts to adjust multiple Keyer settings, the following error message is displayed:

GlbCmd is Off

only Transitions allowed

Select only one Keyer, or set GlbCmd to On. When the GlbCmd is set to On, all commands are sent to the selected Keyers. This property should only be set to On when controlling multiple Keyers (with the same logo) and when you want to change settings such as Gain, Offset, etc., on all the Keyers being controlled.



Name Add

The Name Add menu allows Keyer groups and modules to be assigned a name. Names can then be added to the control panel Name List. This menu contains the following properties:

• Mode selections can be either Single or Group. Set this property to Single to assign a Single Keyer Name, or to Group to assign a Group Name.

• Group contains the group number assigned to the Keyer by the Group ID Hex Switch (on the DSK-6801/3).

Dial in the desired name in the Name field. This field allows alphanumeric input and has a length of five characters. See the following procedure for adding a name:

• Keyer contains the Keyer ID number as set on the DSK-6801/3 module.

• Add is the property that actually adds a name to the Name List maintained by the control panel. The property selections are Yes or No.

To add a name to the Name List:

1. Select Single or Group mode.

2. Choose a Keyer or Group by number.

If you are adding a Group Name, it is recommended that you assign that name to the master module (the Keyer with Keyer ID of 0). The Keyer assigned this Group Name will be designated as the master of the group. The master is the only Keyer that has two-way communication with the control panel.

3. Move to the Name property.

There are five character spaces available in the Name field. Each character space is selected (underlined) using the Left and Right cursor buttons.

Name Add

Mode: Single

Group: 0 Keyer: 1

Name: NAME1 Add: No

The DSK-CPx uses the Name List to provide Keyer and Group names which are available for selection and control. No more than 256 Keyer names can be stored in the control panel at one time.



To create a name, use the Control knobs to add the desired letters, numbers, and other characters to each underlined space selected by the Left and Right cursor buttons.

4. Move to the Add Property and set it to Yes. The Keyer Name has now been added to the Name List, and this Keyer can now be selected by name.

No Keyer may have more than one name assigned to it. The control panel simply replaces the older name with the newer one. No two Keyers may have the same name. As long as a name is in the Name List, it must first be removed from the list before another Keyer can be given that same name. When a name is added to the Name List, the Keyer Module or Keyer Group must be powered up, connected via the XY, bus and have a unique and valid Device Address. Otherwise, the name will not be added to the list. There is a system-generated Keyer Default Name for every Group ID and Keyer ID combination used.

Name Remove

The Name Remove menu looks very similar to the Name Add menu. The difference is that the Del (Delete) property replaces the Add property. This menu is used to delete names from the control panel Name List.

To remove a name from the Name List:

1. Display the Name to be deleted from the Name List. Or alternately, the name will be displayed by selecting the appropriate Keyer and Group number.

2. Select the Delete property and change the setting to Yes. The name will be removed.

Name Remove

Mode: Single

Group: 0 Keyer: 1

Panel Setup1

The Panel Setup1 menu contains the Memory #, Save, and Recall properties. This menu allows you to save and restore various panel setups and also allows the recall of the default panel settings.

A Memory # is used to identify each saved Panel Setup. For example, the figure above shows the Memory # 6 representing a specific panel configuration. Valid Memory #s are 0 to 8; however, Memory # zero (0) is a special read-only memory selection used to store and recall the default Panel Setup.

Therefore, the operator can use only Memory #s 1 to 8.

To save a panel setup:

1. Display the Panel Setup1 menu.

2. Move to the Memory # property and set to the number desired.

3. Move to the Save property. Set the option to Yes.

4. The current Panel Setup and Soft Button menu setups are saved under the Memory # selected. The saved data contains: Type (Single/Group), System menu (On/Off), or Program/Preview (On/Off).

To recall a Panel Setup:

1. Display the Panel Setup1 menu.

2. Move to the Memory # and select the Panel Setup number you wish to recall (0 - 8).

3. Move to the Recall property and set to Yes.

4. The Panel Setup configuration and Soft button configurations that were last saved under the Memory # are recalled and loaded for operation.

Panel Setup1

Memory # Save Recall

6 No No

The Panel Setup menus and the Soft Button menus are associated, in that access to the Soft button menus is through the Panel Setup2 menu. The Soft Button menu settings are saved and recalled along with the Panel Setup menus under the same Memory #.

Selecting of the Memory # 0 recalls and loads the default settings.



Panel Setup2

This menu contains the Cntrst (Contrast), Bklght (Backlight), Menu Out, and Control Pan ID (Panel ID) properties.

• The Cntrst selections are 0 to 15. A zero setting provides little contrast while a setting of 15 produces the most contrast.

• The Bklght selections are 0 to 7. Zero produces a dimmer screen while 7 produces a brighter one.

• The Menu Out setting is the time-out (amount of delay) given before the system reverts the screen display to the Keyer Status menu. The Menu Time-Out selections are:

• None

• 5 seconds

• 15 seconds

• 30 seconds

• 1 minute (default setting)

• The Pan ID (Control Panel) is actually the XY address with settings from 0X0 to 0XFFFF. Use the Control knobs to select the desired Pan ID.

Panel Setup2

Cntrst: 7 Bklght: 5

Menu Out: None

Pan ID: 0000

It is especially important that the Control Panel ID be different from that of every other panel or other device on the XY Bus. If it is not different, you may experience difficulties with the system.



Soft Button

The Soft Button menu allows you to program the Soft buttons in the menu system rather than manually pressing and holding them down. It contains the SB # property (Soft Button # Property) with a selection range of 1 to 5 (one for each Soft button).

• The Type property selections are Menu or Keyer.

• The Menu field displays the name of each control panel menu in order, allowing the operator to scroll through them.

The Property field displays the name of the modifiable properties available on the selected menu (shown in the Menu field). Here you can scroll through the modifiable properties (for the selected menu) displaying one after the other. If the Property field is left blank, the programmed Soft button only jumps to the selected menu (not a property).

For example, in the figure shown above, the Menu field displays Status (Keyer Status menu) and the Property field displays KeyInv (Key Invert).

If the Property field Control knob is turned, the next available modifiable property is displayed in sequence. For instance, as the selections are scrolled through, FTB would be displayed next, followed by Auto.

To set the Type property:

1. Select the SB # that you wish to program.

2. Move to the Type property and set to Menu or Keyer. The Type set determines if the Soft button is programmed to a menu and/or to one of its properties or to a Keyer (or Group) and its settings.

Soft Button

SB #: 2 Type: Menu

Status KeyInv

When the Type property is set to Menu the Soft Button menu is displayed as shown in the figure above.



To display a menu:

1. Display the Soft Button menu.

2. Use the cursor buttons to highlight the SB # Property (Soft Button #). The corresponding property containing the number is underlined.

3. Turn the Control knob to select the SB # button you wish to program. Selections are 1 to 5, one number for each of the Soft buttons.

4. Move to the Type property.

5. Turn the Control knob to set the Type property to Menu

6. Move to the Menu property and use the Control knobs to select the name of the menu you want this Soft button to be programmed to display. The Soft button selected is now programmed to display the selected menu.

To display a property:

1. Follow Steps 1 through 6 as listed above.

2. Move to the Property field.

3. Turn the Control knob to select the property desired.

The Soft button is now programmed to the property selected.

When the Type property is set to Keyer, the second Soft Button menu is displayed as shown above. This menu allows the operator to program a Soft button to a specified Keyer (by name) and as a program or preview Keyer if desired.

• The SB # and Type properties are the same as on the first Soft Button menu.

• The Key1/Prg (Keyer one/program) property contains the name of the Keyer assigned to Program.

• The Key2/Prv (Keyer two/preview) property contains the name of the Keyer assigned to Preview.

Soft button actions/functions take effect at the release of the button.



To select a Keyer or Group to be programmed to a Soft button, the Keyer Modules must already be controlled by the control panel. If they are not, simply add the name of the Keyer or Keyer Group to the DSK-CPx Name List. For more information, see “Name Add” on page 121.

1. Display the Soft Button menu and select the SB # you wish to program.

2. Set the Type property to Keyer.

3. Move to the Key1/Prg property. Select the name of the Keyer or Keyer Group by turning the associated Control knob.

4. To select a second Keyer or Keyer Group, move to the Key2/Prv property value, and select the name of the second Keyer or Group to be programmed to this Soft button.

Be aware of these Soft button Actions:

1. If a Soft button is programmed to a specific menu, that menu is displayed when that Soft button is pressed.

2. If a Soft button is programmed to a specific property on a menu, pressing the Soft button results in the display of the menu containing the specified property. The property value changes when the Soft button is released.

On a menu with three or fewer modifiable properties, Soft buttons cannot be programmed to a specific property by holding the Key down since they are already automatically linked to one of three knobs. On this kind of menu (with three or fewer properties), the Soft button menu can be used to program a Soft button to jump to a specific property. With four or more modifiable properties, the user can scroll through them with the cursor buttons, highlight a specific one, and program it to a given Soft button by holding the Key down.

3. If the property specified is a toggle-type Action property, then pressing the assigned Soft button results in that action being toggled On or Off. If the Action toggled was On, the state is toggled to Off and vise versa; however, the associated menu is not displayed.

4. When more than one Soft button has been programmed to select Program Preview Keyer Pairs and the control panel has Prg/Prv set to On, pressing a Soft button results in the Prg/Prv Keyers being selected for the next transition.

See “Soft Button” on page 127 for important Soft button attributes.


Chapter 5: DSK-CP1/2 Downstream Serial Keyer Control Panel Modes of Operation

Modes of OperationThe DSK-CPx can address the Keyers in three modes that can be overlapped and combined as described later in this section. The modes of operation are:

• Individual (Keyer)

• Group Control

• Program/Preview

In each mode, the control panel configures all settings and initiates all transitions on one or more Keyers. The GPI controls are mirrored to the DSK-CPx.

The Keyer settings on a DSK-CPx can be changed via the GPI, DSK-CPx, or DSK-6801/3 front edge controls. There is no mechanism for locking out controls. If one Keyer is being controlled from the front edge controls and another from the GPI, there will be conflicts. In normal operation, Keyer settings should be modified from one control point only.

Individual ModeThe Individual mode allows the operator to set the parameters of a single Keyer. All settings displayed on the control panel reflect the configuration of the Keyer specified (by name) and selected by the operator. Transitions initiated by the operator via the control panel occur on that specific Keyer only.

Group ModeThe Group mode allows the operator to transition all of the Keyers within a single group. Each group has a Master Module designated by the Keyer ID of 0 (zero). All settings displayed reflect the configuration of the master of the group.

Changing settings on the Master Module using front edge controls, generates a message to the control panel, which then updates all the modules in the group.

If the GlbCmd property is set to On, all Keyer settings can be changed on all Keyers within the group.

Transitions initiated via the control panel occur on all Keyers within the group simultaneously.


Modes of Operation Chapter 5: DSK-CP1/2 Downstream Serial Keyer Control Panel

Transitioning Multiple Keyers with Different SettingsWhen the transition of many Keyer Modules is desired at the same time and each Keyer Module has different Keyer settings, use the following to set transition control:

1. Set the DSK-CPx to Individual mode control.

2. Select a Keyer Module and modify the settings as desired.

3. Repeat Step 2 for each Keyer Module desired in the transition.

4. Change to Group mode control and select the type of transition (Cut, Auto Trans, FTB, or a Manual Fade) desired for the Keyer Modules. All selected Keyers are transitioned together.

Program/Preview ModeThe Program/Preview mode allows you to set the operating parameters on the Keyers in pairs, such that one Keyer represents the program output and the other a preview of the program after the next transition occurs.

In this mode, all Keyer settings are mirrored to both Keyers, and all transitions occur opposite to each other. For example, if the Program Key is faded Off, the Preview Key will fade On. The only exception to this mirror effect occurs when the program is faded to or from black. Since a black preview would not be helpful, the preview never fades to black.

A maximum of five Program/Preview pairs can be controlled by the DSK-CPx.


Chapter 5: DSK-CP1/2 Downstream Serial Keyer Control Panel Setting the Device Address

Setting the Device AddressEach DSK-6801/3 connected to a DSK-CPx must have a unique Device Address. The Device Address is achieved by setting the Group ID and Keyer ID on each Keyer Module. The following procedures show how to add a name to the Name List, and set up the Device Address, Group, Panel and Keyer IDs.

Setting a Group IDThe Group ID is set using the Hex SW4 Switch located on top of the Keyer Module. For detailed information, see Figure 5-15 “Group ID Hex SW4”.

Figure 5-15. Group ID Hex SW4

1. To set a Group ID, turn the Hex switch (see Figure 5-15 “Group ID Hex SW4”) to one of the 16 positions available (0 to F). The number/letter selected is now the Group ID. For example, if the Module Hex switch is set to position 6, that module has a Group ID of 6 and is controlled with Group 6.

GroupID

SW4HEX

HEX SW1

TOG SW2

TOG SW3


Setting the Device Address Chapter 5: DSK-CP1/2 Downstream Serial Keyer Control Panel

2. To change a Group ID, simply change the Keyer Module Hex switch to the desired position. For example, if the Hex switch is currently set to 6 and the operator now wants this module to be in Group A, changing the switch from position 6 to A gives this module a Group ID of A.

Within each Group there is a Master Module. The Master Module is the only Keyer that has two-way XY Bus communication with the DSK-CPx. Within a group, the Keyer with the Keyer ID of 0 (zero) is designated as the Master Module.

Changing the Master Module settings at the keyer level (via front edge controls) creates a message which is sent to the control panel, allowing it to update all Keyer settings within that Group.

If a Slave Keyer (non-master) has its settings changed (via front edge controls), the control panel is not notified or updated.

Setting a Keyer IDThe Keyer ID on a DSK-6801/3 module consists of selecting an address value in both the upper and lower part of each address setting.

The DSK-6801/3 Keyer ID is set as follows:

1. Turn the front Hex SW1 to Position 0, toggle SW2 Up or Down until the Shift State 2 LEDs are illuminated. The system is now in Shift State 2.

2. Turn Hex SW1 to position B.

3. Toggle SW2 to select the desired upper portion of the address.

4. Pressing up on SW2 adds 16 to the address value.

5. Pressing down on SW2 subtracts 16.

6. Move Hex SW1 to position C.

7. Toggle SW2 to select the lower portion of the address.

8. Press up on SW2 to add 1 (one) to the address value.

9. Press SW2 down to subtract one. The address is displayed on the LEDs in Binary.

When selecting the address, see Figure 5-16 on page 134 for reference.


Chapter 5: DSK-CP1/2 Downstream Serial Keyer Control Panel Setting the Device Address

Setting a Device AddressSetting a Device Address consists of setting a Group ID and Keyer ID. See Figure 5-16 on page 134.

Figure 5-16. Setting a Device Address

1. Set Hex SW4 to the Group position desired (0-F).

2. Set the Keyer ID address using Shift State 2 and Hex SW1 in position B (for upper four address bits) and toggle SW2 until desired number is achieved. See “Setting the Panel ID” on page 135 for numbering information.

3. Move Hex SW1 to position C for the lower four address bits. Toggle SW2 until the desired number is achieved.

4. Give the Keyer a name using the Name Add menu. See “Name Add” on page 121 for detailed information.

5. Assign the Keyer to a Soft button if it will be used in Multiple mode or in Program/Preview mode.

6. Designate the Keyer as Key1/Pgm (program) or as Key2/Prv (preview) side. See “Program/Preview Mode” on page 131 for more information.

7. List the new Device Address on the Name List maintained by the DSK-CPx. See “Name Add” on page 121 for more information.

8. Label the Keyer with the appropriate information to simplify troubleshooting and system additions. For example, affix a label on the Keyer with the name or group assigned it.

Chapter 5: DSK-CP1/2 Downstream Serial Keyer Control Panel Installation

InstallationThere is a great deal of information to consider when setting up a system. It is suggested you read this chapter for reference and check the XY connection diagrams and operational modes for information that will help determine how to set up the system as desired.

Rear Module XY ConnectionsFor the control panel to control the Keyers, both the control panel and Keyers must be connected to the XY Bus. This is achieved by connecting a cable from the XY BNC on the rear of the DSK-CPx to the XY connectors on the frame containing the Keyer Module. Once this connection is made, the control panel is capable of controlling that Keyer.

To connect the XY Bus to the rest of the Keyers, simply connect a cable from the XY Loop connector on the frame to the XY connector on the next Keyer’s frame connections, as illustrated in the following diagram.

The order in which the Keyers are attached to the XY Bus is generally unimportant; however, if any Keyer is more critical than another, it is recommended that it be connected as early as possible on the bus. This is only a concern when the XY cable is disrupted, and Keyers beyond the disruption are unreachable.

Other fail-safe mechanisms (such as GPIs) can be set up to coexist with the DSK XY network.

For EMI compliance, the DSK-CPx must be terminated at both ends.


Installation Chapter 5: DSK-CP1/2 Downstream Serial Keyer Control Panel

Figure 5-17. XY Connections

Once the DSK-CPx has been connected to the Keyers over the XY Bus, the Keyers should be given appropriate names. This is not required, but will make it easier to select the appropriate Keyer. The Keyers can also be assigned to Soft buttons. This is only required if the Keyers will be used in Program/Preview mode. Once the Keyers are given names and designated to the Program or Preview side, label the Keyers with the name to simplify troubleshooting and system additions.

DSK Keyer Module Setup RequirementsDSK keyer Module set up requirements are listed below:

• Jumper settings

• Hex switch settings for Group/Keyer ID.


System Applications Chapter 5: DSK-CP1/2 Downstream Serial Keyer Control Panel

System ApplicationsConfiguration examples are provided in this section to help set up different types of systems. However, configurations are not limited to the examples shown. The operator is free to interconnect and control the DSK-CPx system as desired. There are several types of video sources shown, and many other types are available and can be used. Also shown are different ways of terminating the XY Bus. In the following figures are several DSK-CPx system configurations and suggestions for setting up Group IDs, Keyer IDs, and Keyer names. A few things to note in all of the examples given are:

• The names are set to values that help to identify a DSK-6801/3 module and what it keys, or the program input on a DSK-6801/3 module and what it keys.

• Each Keyer or group of buttons is given a name which can be used to select a specific Keyer/Group to be controlled.


Chapter 5: DSK-CP1/2 Downstream Serial Keyer Control Panel System Applications

Connecting a Single Keyer SystemIn this example, one DSK-CPx controls one Keyer Module.

• A DSK-6801/3 has a default Keyer ID value of zero, so the Keyer ID value does not need to be changed.

• The Group ID is set to the value indicated on the Group ID Hex switch.

• The Panel ID defaults to zero, so it should be changed to one (expressed as 0 x 0001) (see Figure 5-18 “Single Keyer System”).

Connecting a Multi-Level Keying SystemIn this example of multi-level Keying, the Program Output of one Keyer Module is connected to the Program Input of another Keyer Module. The XY loop-through connections on the rear of the Keyer Module frame are used to connect the frame to the XY Bus.

The suggested name for each Keyer Module is related to its video source. This way you control the CG Keyer, simply dial-up the CG Keyer name on the DSK-CPx, and then make the changes to that Keyer Module.

Alternatively, the operator can assign each Keyer Module to a programmable Soft button. When a Soft button is pressed, the LED is illuminated and changes can be made to the selected Keyers. The changes can be “Key” transitions or modification of the Keyer settings. Set the GlbCmd Property to Off when multiple soft buttons have been programmed to select Keyers.

Connecting a Program/Preview SystemA Program/Preview system is the most complicated system to set up. The following figure shows Keyer Modules on the program path named with the suffix PGM and the Preview Keyers named with the suffix PRV. The prefix of the Keyer name relates to its order in the Program/Preview path. The first Keyer Module in the Program path has the prefix K1 and the last Keyer in the Program path has the prefix K5. The Keyers in Program and Preview paths are cascaded one after the other.

The Key sources are identical for each pair in the Program/Preview paths. The Keyers in the Preview path show what the Program Output will look like after a transition.

Each Program/Preview pair should be assigned to a Soft button; otherwise, control of Keyers in the Program/Preview mode becomes difficult.



Procedure for Setup of a Program/Preview SystemThe Program and Preview Keyers are organized in pairs:

Make sure the Keyers are on the Name List; if not, add them.

1. Program each Soft button with the name of the Prg/Prv (Program and Preview) Keyer pairs.

2. Set the DSK-CPx into Prg/Prv mode in the System Setup menu. Set the Prg/Prv field to Yes to enable the Prg/Prv mode.

3. To select multiple Prg/Prv pairs for transitioning, program more than one Soft button with a Program/Preview Keyer pair and set the GlbCmd property to Off.

For a demonstration, see Figure 5-20 “Program/Preview System”on page 144.



Program Preview System

Figure 5-20. Program/Preview System



Connecting a Group SystemIn this example, the Keyer Modules that key the weather warning are named with the suffix WTR. The Keyer Modules that key the network logo are named with the suffix LGO. The prefix of each Keyer name corresponds to the video source on the Program Input.

Each set of Keyers (weather warning or logo) have been set to operate within the same Group, meaning they have the same Group ID. Therefore, the group of Keyers that key the weather or the Group that keys the logo can be transitioned at the same time (as one Group).

Programming a Soft button to select a group allows the transition of all Keyers in that group at the same time. Program Soft buttons to the other groups and the operator can select more than one Group at a time (press more than one Soft button) and transition all of the selected Groups at the same time.

For a demonstration, see Figure 5-21 “Group System Configuration”on page 146.

Quick Reference Guide

OverviewThis Quick Reference Guide contains sections which enable the operator to quickly install a DSK-CPx and address a Keyer Module. This Appendix also contains a section on Error Messages, Troubleshooting, and the Diagnostic Mode.


Appendix A: Quick Reference Guide Setting Control for One or More Keyers

Setting Control for One or More Keyers1. Identify how the Keyer Module will be used. For example, if Keyers

will be transitioned together (the majority of the time), then set the Group ID of each Keyer to the same value (they are all in the same Group).

2. If there are less than 16 Keyers or if you wish to transition any combination of Keyers independently, then, give each Keyer a unique Group ID. See “Setting a Group ID” on page 132.

3. Give each Keyer Module a Keyer ID. See “Setting a Keyer ID” on page 133.

4. Set the mode of operation on the control panel via the System Setup menu.

5. Set the jumpers on the DSK-6801/3 to accept the XY Bus input.

6. Assign a Panel ID to the DSK-CPx. See “Setting the Panel ID” on page 135.

7. To add the Keyer Modules to the control panel Name List, see “Name Add” on page 121.

8. Select the Keyer or Group to be controlled. Change the Keyer settings and/or transition the Key on the Keyer Modules. See “Menu Controls” on page 108, and see “Dedicated Transition Buttons” on page 96.

9. Do not power up more than one frame of DSK-6801/3 modules at a time.


Setting Control for One or More Keyers Appendix A: Quick Reference Guide

DSK Control LayoutThe DSK-CPx provides the capability to control and change operational settings on the DSK-6801/3 Keyer Modules. The control panel features five dedicated buttons for commonly used operator functions and five Soft programmable buttons for panel customization.

The DSK-CPx has three major functional areas: the Transition controls area, the Settings area, and the Fade to Black button, each of which is described in the following section.

Figure A-1. DSK-CPx Layout

SettingsTransitionControls

Dedicated Buttons

Programmable SoftButtons

Transition Controls

The Transition controls determine how a logo will be used by the Program Output. The logo will be one of the following:

• Cut

• Faded

• Wiped on

• Wiped off the program output

Settings

The Settings area consist of the following:

• Dedicated Setup buttons which can select Control menus, change menu properties, or select Keyers.

• Programmable Soft buttons can be programmed to select specific menus, change menu property settings, and to select Keyers/Groups.

• An LCD screen which displays menus with property settings available for modification.

Certain menus control the Keyer settings, some change the control panel settings, and some modify system-related settings. Any menu that allows modifications to Keyer settings displays the Name of the currently controlled Keyer (or Group) on the LCD screen which allows the user to distinguish between Keyers or Groups when controlling more than one.

Once a menu is selected and displayed, Up and Down white cursor buttons are used to scroll between menu selections. The Left and Right cursor buttons are used to highlight the adjustable properties on the menu displayed, and the Control knobs change the displayed values. See “Menu Controls” on page 108 for detailed information.

Fade to Black Button

The Fade to Black button fades a Keyer Module program output to black. The fade rate can be changed on the Rates Setup menu (accessed by the Trans Setup dedicated button).



MenusThe DSK-CPx contains 16 menus. The menus are divided into five categories which are represented by the five control menus:

1. Keyer Setup contains properties for Keyer setup.

2. Trans Setup contains settings for Transition Rates, Mask, Wipe, and Chroma Key.

3. Panel Setup contains panel settings, Soft programmable button setup, and Keyer status information.

4. System Setup contains mode settings, Name Add and Remove settings, and GPI settings.

5. Keyer/Grp ID contains Keyer and Group ID information.

The DSK-CPx menus are linked in a simple list format. This linked format has a set flow as illustrated in Figure 5-2. The dedicated Setup buttons are pre-programmed to display a specific menu when pressed. Each of these menus is a control menu (one of the five listed above), and each controls its own group of linked menus. The menus linked to a control menu are selected by using the Up and Down white cursor buttons to scroll through the linked menus.

Selecting and Changing a MenuTo make changes to the modifiable property fields contained on the various menus, perform the following:

Use the Control knobs to select (display) the menu desired.

1. A menu can be selected by pushing a dedicated setup button, by scrolling with the Up and Down cursor buttons, or by pushing a programmed Soft button.

2. Once the selected menu is displayed, use the Left and Right cursor buttons to move between menu properties. The property Label field is highlighted, and the modifiable property field is underlined.

3. Turn any Control knob to change to display to the desired value. See “Using the Control Knobs” on page 109 for more information. On menus with three or fewer properties, each property is controlled by the Control knob directly below the property.

Summary of Control ModesThere are four modes of control which can be overlapped and combined as desired:

• Individual Keyer control

• Group control

• Program/Preview control

These modes of operation are dependent on how the video signals are connected to the Keyer Module. The control panel configures all settings and initiates all transitions of the Keyers in each mode. See “Modes of Operation” on page 130 for more information.



XY Bus ConnectionsFor the control panel to control the Keyers, they must all be on the same XY Bus. Connect a cable, from the XY BNC on the rear of the DSK-CPx, to the XY connectors on the Keyer Module. See “Setting a Device Address” on page 134 for more information.

Figure A-3. DSK-CPx XY Connections

The DSK-CPx controls the Keyer Modules via the Leitch XY Serial Bus (see “Rear Module XY Connections” on page 136 for more information). The DSK-CPx can control any group of DSK-6801/3 Keyer Modules. The ability of the control panel to control any group of DSK-6801/3s is most helpful in a situation where one control panel resides in each studio (of a production facility), and all of the Keyer Modules are centrally located. The control of Keyer Modules can be simplified. For example, if during normal operation, all of the Keyers are to be transitioned at the same time, then set the control panel to Group mode and assign all of the Keyer Modules to the same Group ID address. See “Setting a Group ID” on page 132 for more information.

Setting a Device AddressEach Keyer must have a unique Device Address by which the control panel recognizes and controls the modules. Combining the Keyer ID and the Group ID results in a unique Device Address. See FigureA-4. DSK-CPx Device Address.

Figure A-4. DSK-CPx Device Address

To assign a Keyer Module a Keyer ID and Group ID use the Hex and Toggle switches on the DSK-6801/3 modules. See “Setting the Device Address” on page 132 for more information.
