7.10 Input levels and formats
The SAA7128H; SAA7129H expects digital Y, C
accordance with ITU-R BT.601 .
For C and CVBS outputs, deviating amplitudes of the color difference signals can be
compensated by an 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
(GY) and color difference signals (GCD).
Reference levels are measured with a color bar, 100 % white, 100 % amplitude and
100 % saturation.
