Luma peak A: Use of the luma peak as a video amplitude reference for the back-end feed-forward type AGC
algorithm.
0 = Enabled (default)
1 = Disabled
Color burst A: Use of the color burst amplitude as a video amplitude reference for the back-end.
NOTE: Not available for SECAM, component, and B/W video sources.
0 = Enabled (default)
1 = Disabled
Sync height A: Use of the sync height as a video amplitude reference for the back-end feed-forward type AGC
algorithm.
0 = Enabled (default)
1 = Disabled
Luma peak B: Use of the luma peak as a video amplitude reference for the front-end feedback type AGC
algorithm.
0 = Enabled (default)
1 = Disabled
Composite peak: Use of the composite peak as a video amplitude reference for the front-end feedback type
AGC algorithm.
NOTE: Required for CVBS and SCART (with color burst) video sources.
0 = Enabled (default)
1 = Disabled
Color burst B: Use of the color burst amplitude as a video amplitude reference for the front-end feedback type
AGC algorithm.
NOTE: Not available for SECAM, component, and B/W video sources.
0 = Enabled (default)
1 = Disabled
Sync height B: Use of the sync height as a video amplitude reference for the front-end feedback type AGC
algorithm.
0 = Enabled (default)
1 = Disabled
NOTE: If all 4 bits of the lower nibble are set to logic 1 (that is, no amplitude reference selected),
then the front-end analog and digital gains are automatically set to nominal values of 2 and
2304, respectively.
If all 4 bits of the upper nibble are set to logic 1 (that is, no amplitude reference selected), then
the back-end gain is set automatically to unity.
If the input sync height is greater than 100% and the AGC-adjusted output video amplitude becomes less than
100%, then the back-end scale factor attempts to increase the contrast in the back end to restore the video
amplitude to 100%.
