Description
0 = V/B data channel coming from the D1 interface left unchanged
1 = V/B MSB of data coming from the D1 interface is inverted.
0 = Video programming system data insertion disabled
1 = Video programming system data insertion enabled
Fifth byte of video programming system data
11th byte of video programming system data
12th byte of video programming system data
13th byte of video programming system data

Phase of encoded color subcarrier (including burst) relative to
horizontal sync. Can be adjusted in steps of 360/256 degrees.
Variable gain for Cb signal; input representation is in accordance
with CCIR656. This is the digital gain for SD-Data path
White to black = 92.5 IRE
GAINU can be adjusted in a range from -2.17 x nominal
to 2.16 x nominal
GAINU=0 (output subcarrier contribution of U = 0)
GAINU=0x76 (output subcarrier contribution of U = nominal)
White to black = 100 IRE
GAINU can be adjusted in a range from -2.05 x nominal
to 2.04 x nominal
GAINU=0 (output subcarrier contribution of U = 0)
GAINU=0x7D (output subcarrier contribution of U = nominal)
GAINU=0x6A (nominal Gain for Secam encoding)
