Preliminary specication
PAL/NTSC/SECAM video decoder with adaptive PAL/NTSC
comb lter, VBI-data slicer and high performance scaler
SAA7114H
Fig.18 CVBS (raw data) range for scaler input, data slicer and X-port output.
CVBS levels with default settings RAWG[7:0] = 64 and RAWO[7:0] = 128.
Equation for modification of the raw data levels via bytes RAWG and RAWO:
It should be noted that the resulting levels are limited to 1 to 254 in accordance with “
ITU Recommendation 601/656”.
