1.1. FUNCTIONAL DESCRIPTION
Composite analog video is converted to 12 bit parallel data and decoded to 4:2:2 digital component.
Various video processing functions (gain, saturation, noise reduction, etc) are performed during the
decoding process.
In the 7837CD2-A4 version, the 4 channels of audio (2 channels per video path) are converted from
balanced analog to digital PCM. In the 7837CD2-A8 version, 8 channels (4 channels per video path) of
audio are converted from balanced analog to digital PCM. The digital audio is then delayed to match the
delay in the video synchronizer. For the 7837CD2-A4 and –A8, analog audio is delivered as unbalanced
75 Ohm AES audio on the designated BNCs. The same audio is also embedded on the associated SDI
output video.
Program video goes to a SDI parallel to serial converter.
For module edge control, the hardware mixes (keys) the on-screen display (OSD) control information onto
the video streams currently being controlled, and passes it through a monitoring quality composite
encoder for user viewing.

2. Installation
The 7837CD2 modules come with a companion rear plate and occupy one or two slots in the 7800FR or
7800FR frame. Figure 2-1 provides a drawing of each of the rear panels. For information on mounting the
rear plate and inserting the module into the frame see section 3 of the 7800FR chapter.
Figure 2-1: 7837CD2 Rear Panels
2.1. VIDEO IN AND OUT
Connect a source of composite analog (NTSC or PAL-B) video to either or both BNC’s labeled ANLG A/
ANLG B. Connect a reference black signal to the REF IN BNC. Decoded video with embedded audio is
available on the SDI OUT (1A/2A), (1B/2B) BNC’s, two for each channel. Decoded and re-encoded analog
video with control text is available on the MON OUT output BNC. If the module is not present or the power
is off, there will be nothing on any of the outputs. The module is designed to support simultaneous
decoding of two video signals of the same format.

Revision 1.0 Page - 5
2.2. AUDIO IN AND OUT
The audio versions of the CD2 (-A4 and –A8) have audio paths through the module that are
delayed/synchronized with the video. The –A4 version performs A to D conversion on 4 balanced analog
inputs (1 stereo pair per video channel), delays the audio to match the associated video, and outputs 1
AES channel that is synchronous to the associated video. One half group of delayed audio is embedded
on the output video. The –A8 version performs A to D conversion on 8 balanced analog inputs (4 channels
per video), delays the audio to match the associated video, and outputs 2 AES channels that are
synchronous to the associated video. One full group of delayed audio is embedded on each video output.
The –A4 and –A8 versions of the CD2 use a removable terminal strip to connect audio. To connect audio,
pull out the removable terminal strip and, with a small screw driver, connect bare wires following the
connections on the rear panel. If the audio is unbalanced (single-ended), connect the ground to both the
ground input and the –ve input while the signal is connected to the +ve input. Push the terminal strip back
into the rear panel making sure there is enough slack in the cabling to not put pressure on the connector.
48kHz unbalanced 75 Ohm AES is available on the AES OUTPUT BNCs.
The AES outputs are always synchronous to the output video. This means that the AES is
frequency/phase locked to the video with an exact relationship between the number of audio samples and
the number of output video frames.

5. ON SCREEN MENUS
5.1. NAVIGATING THE ON SCREEN MENU SYSTEM
A rotary encoder allows card edge navigation on a set of On-Screen menus used to configure the module.
On-Screen menus are available only on the MON OUT BNC for the 7837CD2 series of modules. This
ensures that On-Screen menus are not accidentally put on-air.
To enter the On-Screen menu system, press the pushbutton once. This will bring you to the main setup
menu where you can use the rotary knob to move up and down the list of available sub-menus. An arrow
(>) moves up and down the left hand side of the menu items to indicate which item you are currently
choosing. Once the arrow is on the desired item, press the pushbutton to select the next menu level.
On all menus, there are two extra selectable items: Back and Exit. Selecting Back will take you to the
previous menu (the one that was used to get into the current menu) while Exit will return the display to its
normal operating mode. On the main menu, BACK and EXIT will both take you to the normal operating
mode.
Once in a sub-menu, there may be another menu layer, or there may be a list of parameters to adjust. If
there is another set of menu options, use the toggle switch to select the desired menu item and press the
pushbutton.
To adjust any parameter, use the rotary knob to move up or down to the desired parameter and press the
pushbutton. The arrow will move to the right hand side of the line (<) indicating that you can now adjust
the parameter. Using the rotary knob, adjust the parameter to its desired value. If the parameter is a
numerical value, the number will increase or decrease by turning the rotay knob left or right. If the
parameter contains a list of options, you can cycle through the list in the same fasion.
When you have stopped at the desired value, depress the pushbutton. This will update the parameter to
the selected value and move the arrow back to the left side of the parameter list (>). Continue selecting
and adjusting other parameters or use the BACK or EXIT commands.

Closed captioning has been defined to NOT have a 7.5 IRE pedestal,
but it is placed on the first active line of video where there may be a
pedestal. This depends on the upstream closed captioning and/or
composite encoder that generated the video. When decoding
composite video with closed captioning, care must be taken to not
remove a pedestal if it is not there.
This control, when set to Don't remove setup, will not remove 7.5 IRE
pedestal from line 21. This is the default state for properly generated
captioning.
When set to Remove setup, the 7.5 IRE pedestal will be removed
from line 21. Note that this state is only valid if the preceding NTSC
Setup Pedestal control is set to "Remove".
Blank is used to remove captioning from line 21. This is most useful
for removing captioning when going into an up-converter.

On/off mode control of processing of non-Time Base Corrected video
input signals is affected by this menu item.
When set to "On", the input video processing is modified to be more
tolerant of non-time base corrected signals.
5.4.8. Detail Enhancement Threshold
Video Path 1
Analog Video Processing
Detail Threshold
very low,
low,
medium,
high
Experimentally, set this to a level that will apply detail/edge
enhancement without enhancing the input noise.
Lower thresholds will apply enhancement to smaller edge transitions
thus bringing out smaller details. Unfortunately, if the threshold is set
too low, input noise will eventually be enhanced making the picture
look noisier.

When an edge passes the threshold set with the previous control
(Detail Enhancement Threshold), the amount of enhancement is
selected with this control. The higher the number, the more
enhancement is applied.

5.5. CONFIGURING THE OUTPUT VIDEO SETTINGS
The Output Video Settings menus are used to configure parameters associated with the output video
processing functions. The chart below shows the items available in the Video menu. The following
sections provide detailed information about each of the parameters.
Loss of video Selects the action to take when the input video is missing.
525 H phase Sets the horizontal phase of the output signal to a NTSC Genlock
reference input.
625 H phase Sets the horizontal phase of the output signal to a PAL Genlock
reference input.
525 V phase Sets the vertical phase of the output signal to a NTSC Genlock
reference input.
625 V phase Sets the vertical phase of the output signal to a PAL Genlock
reference input.

525 H phase
0 to 1715
0
With this control, you can set the horizontal timing of the output video
with respect to the Genlock reference input when operating in
NTSC/525 video mode. Setting this control to 0, keeps the monitoring
output video in time with the Genlock reference. The SDI output will
be a couple of microseconds advanced to the Genlock reference.
Increasing the value will delay the output video in one-sample
increments.
5.5.3. Setting the Horizontal Phase of the Output Video – PAL-B/625 Video

With this control, you can set the horizontal timing of the output video
with respect to the Genlock reference input when operating in
PAL/625 video mode. Setting this control to 0, keeps the monitoring
output video in time with the Genlock reference. The SDI output will
be a couple of microseconds advanced to the Genlock reference.
Increasing the value will delay the output video in one-sample
increments.
