G/Y gain [7:0]
G/Y component gain (contrast):
0000 0000 = minimum
1000 0000 = default
1111 1111 = maximum
For component video outputs, the total luma gain relative to the nominal luma gain as a function of the G/Y gain[7:0] is as follows:
Luma gain = (nominal_luminance_gain) × (G/Y gain [7:0] / 128)

1000 0000 = default
1111 1111 = maximum
For component video, the total B/Pb gain relative to the nominal B/Pb gain as a function of the B/Pb gain [7:0] setting is as follows:
B/Pb Gain = (nominal_chrominance_gain) × (B/Pb gain [7:0] / 128)

G/Y offset [7:0]
G/Y component offset (brightness):

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 offset [7:0] is as
follows:
Black Level = nominal_black_level + (G/Y offset [7:0] – 128)
