BBG-1034-AUD-PRO-DSP Function Menu List and
Output Video Mode Controls
Allows selection of each of the four video output coaxial
connectors as processed SDI out or reclocked SDI out.
Also provides CVBS parameter controls and test
pattern output controls for CVBS output.
• Output Video Crosspoint For each SDI output port supported by the device, provides a crosspoint
for routing program processed video or selected-input reclocked to an
SDI output.
In this example, SDI OUT 1. SDI OUT 3, and SDI OUT 3 are outputting
Program (procesed) video out, with SDI OUT 2 providing SDI IN A
reclocked input video.
Note: Outputs set to Input Reclocked will pass input SDI regardless of
Input SDI Raster Size / Frame Rate Filtering. Input filtering applies
only to the program video path.
• ST352 VPID Insertion/Pass-Thru Select Selects from default Regenerate mode and special Pass-Through mode
(see below for important usage notes).
• Regenerate makes certain ST352 is marked for whatever the card is
passing, or if the payload is being modified by the card. (An example of
where ST352 would have to be modified would be if the card
Framesync is user-set to change the frame rate from 59.94 to 60.)
• Pass-Through will extract and preserve the ST352 information from
input SDI, and re-insert it on the output regardless of any changes the
card has locally done to identifying characteristics carried in the ST352
metadata.
In all normal usages, it is recommended to leave this control
set to default Regenerate setting. This ensures that
downstream devices will “see” ST352 that represents the
payload being provided by the card. Pass-Through is only
used in highly specialized cases where special ST352 data
must be preserved (even if the data may not match the
payload).
Provides CVBS output parameter controls and test
pattern output controls
• CVBS Oversampling and Color Controls • Oversampling enables or disables video DAC oversampling.
Oversampling can improve rendering of motion for down-conversions to
the CVBS SD analog output.
• Color enables or disables chroma content in the CVBS output.
• CVBS Test Pattern Generator Control Enables manual insertion (replacement) of CVBS output video to instead
output 75% color bars.
