Table 3-21. B/Pb Saturation

Subaddress 12h

Default 80h

7 6 5 4 3 2 1 0

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)

Table 3-22. G/Y Brightness

Subaddress 14h

Default 80h

7 6 5 4 3 2 1 0

G/Y brightness[7:0]

G/Y brightness [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 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)

Table 3-23. AVID Start Pixel

Subaddress 16h–17h

Default 55h/5Fh

Subaddress 7 6 5 4 3 2 1 0

16h AVID start [7:0]

17h Reserved AVID active Reserved AVID start [9:8]

AVID active

0 = AVID out active in VBLK (default)

1 = AVID out inactive in VBLK

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.
