B/Pb saturation[7:0]
B/Pb saturation [7:0]: This register works only with YPbPr component video. For RGB video, use the AFE gain registers.
0000 0000 = minimum
1000 0000 = default
1111 1111 = maximum
For component video, the total Pb gain relative to the nominal Pb gain as a function of the B/Pb saturation[7:0] setting is as follows.
B/Pb Gain = (nominal_chrominance_gain) × (B/Pb saturation[7:0] / 128)

For component video, the output black level relative to the nominal black level (64 out of 1024) as a function of G/Y brightness[7:0] is
as follows.
Black Level = nominal_black_level + (G/Y brightness[7:0] - 128)

AVID start [9:0]: AVID start pixel number, this is a absolute pixel location from HS start pixel 0.
The TVP5160 decoder updates the AVID start only when the AVID start MSB byte is written to. The AVID start pixel register also
controls the position of the SAV code. If these registers are modified, then the TVP5160 decoder retains the values for each video
standard until the device is reset. The values for a particular video standard must be set by forcing the decoder to the desired video
standard first using register 02h then setting this register. This must be repeated for each video standard where the default values need
to be changed.
