DSK BORDER FILL – The fill source for a PGM/PST wipe border or
DSK border.
PGM (Program) – The source selected on the Program bus.
PST (Preset) – The source selected on the Preset bus.
DSK FILL – The 4:2:2 fill source selected for the DSK.
DSK AUX – The 0:2:2 part of a 4:4:4 fill source selected for the DSK if
the 4:4:4 Chroma Key option is installed.
DSK KEY – The key source selected for the DSK.
DSK MASK – The mask source selected for the DSK; also used as the
0:2:2 part of the key feed if the 4:4:4 Chroma key option is installed.
FS 1,2 IN – The video sources selected as the framestore inputs.
INTERNAL DVE CH A VIDEO SEND – The source selected for
channel A of the internal DVE option. This source is always a full color
video signal.
INTERNAL DVE CH B VID/KEY SEND – The source selected for
channel B of the internal DVE option. This source can be either a full
color video signal for Video/Video mode or a monochrome key signal
for Video/Key and Video-Key/Shadow modes.
INTERNAL DVE CH A TEXTURE SEND – The source selected as the
SurfaceFX

texture input for channel A of the internal DVE option.
This source can be either a full color or monochrome video signal.
INTERNAL DVE CH B TEXTURE SEND – The source selected as the
SurfaceFX

texture input for channel B of the internal DVE option.
This source can be either a full color or monochrome video signal.
Color Corrector [3]
There are seven available Color Corrector options, one for each bus row:
Background A, Background B, Fill 1, Fill 2, Program, Preset, and DSK
Fill.
The color correctors let you make adjustments in either YUV or RGB
color space. YUV video input at the standard 4:2:2 sample ratio can be
upsampled to 4:4:4, then transcoded into RGB to provide true RGB color
correction; also, YUV sampled at 4:4:4 is directly transcoded to RGB. In
either case, after correction, the video is transcoded, downsampled, and
output as YUV 4:2:2 video.
With the 4:4:4 Chroma Key option, you can input key fill signals (Fill 1,
Fill 2, and DSK Fill) to the 8150 by using two standard 4:2:2 inputs,
processing them at the 4:4:4 sample rate directly. The normal color
corrector fill video input handles the 4:2:2 part of the 4:4:4 signal. The
Aux color corrector input handles the 0:2:2 part. This complements
optional 4:4:4 chroma key extraction in the Key processor, which uses
