Note: In one channel HD mode the processing is the same as above just without the Video B
input.
Video+Key Mode The Video+Key mode differs from the Video+Video mode
only in that the board processes the B input as the key signal, with additional
clip, gain and H phase adjustments. Note that the "chroma" part of the B cir-
cuitry is not used since key signals are monochrome.
The A/B Combiner's key output is a transformed version of the input, and not
the raster-based signal seen in the Video+Video mode. The B key transform is
independent of the A video transform.
