ABSTRACT:
Method for controlling the digital chrominance signal of a color television receiver depending upon the amplitude of the burst signal and color contrast, which includes multiplying the digital chrominance signal and the burst signal in a multiplier with a given coefficient, forming a mean value of the burst amplitude from an output signal of the multiplier, comparing the mean value of the burst amplitude with a nominal value corresponding to a desired color contrast setting, and changing the given coefficient corresponding to the result of the comparison, and an apparatus for carrying out the method.
