    Abstract: A method and circuits for demodulating color video signals into trisequential form for recording and to recombine the trisequential signals into composite color video signals, using substantially the same method and circuit elements for both demodulation and recombination, where the demodulated trisequential signals have respectively the same phases as the phases of the received chrominance signals.
