ABSTRACT:
In a PAL system chrominance signal processing circuit, a color burst signal is delayed by one horizontal period, a signal representing the difference between a non-delayed burst signal and the color burst signal delayed by one horizontal period is determined, a phase distortion is judged on the basis of a color sub-carrier and said difference signal and the phase of the carrier chrominance signal is corrected on the basis of this judged result.
