5.4.1 PGM IN
PGM IN is a BNC that receives input video for the Program chain. The same signal can also be routed to the Preview
chain if required.
If an invalid SDI signal is present then the input to the Program Channel will revert to black video. Alternatively a color
field or test pattern may be substituted in place of valid SDI.
