Video Input Source
The Video Input Source control is used to select which of the program inputs are to be used for video
processing. The 7812UDXD has two program inputs PGMA and PGMB. This control allows the user to
select either of these inputs for audio/video processing. In this control, select PGM IN A BNC to process
video supplied on PGM IN A through the up/down/cross conversion paths. Select PGM IN B BNC to
process video supplied on PGM IN B through the up/down/cross conversion paths. Select Auto to enable
the card to automatically fail-over to the alterative input BNC should video on the BNC in active use
become invalid for any reason. When the +3D option is ordered you will also have selections on which of
the inputs are receiving the left and right eye information in dual link. The drop down for Video Input
Source appears as follows:

SD Blanking
With this control, you can adjust which standard definition lines will be blanked prior to processing SD
input signals. It is customary to blank line 21 where closed caption information may be present. Note that
the caption translation process will still occur as expected even when line 21 is blanked. This control
simply prevents caption waveforms from being processed as video. The drop down for SD Blanking
appears as follows:
