Product specification
Digital video encoder
SAA7102; SAA7103
7.18
Input levels and formats
The SAA7102; SAA7103 accepts digital Y, C
B
, C
R
or RGB data with levels (digital codes) in accordance with
“ITU-R BT.601”; see Table 24.
For C and CVBS outputs, deviating amplitudes of the colour difference signals can be compensated for by independent
gain control setting, while gain for luminance is set to predefined values, distinguishable for 7.5 IRE set-up or without
set-up.
The RGB, respectively C
R
-Y-C
B
path features an individual gain setting for luminance (GY) and colour difference signals
(GCD). Reference levels are measured with a colour bar, 100% white, 100% amplitude and 100% saturation.
