ABSTRACT:
A multiplexed color video signal recording and reproducing apparatus comprises a first circuit for producing a time division multiplexed signal in which one or two compressed color difference signals are multiplexed with the phase inverted for every predetermined horizontal scanning periods, a second circuit for producing a multiplexed color video signal by multiplexing the time division multiplexed signal with a non-compressed luminance signal, a third circuit for recording and reproducing the output signal of the second circuit on and from a recording medium, a comb filter circuit supplied with a reproduced signal from the third circuit, a fourth circuit for obtaining reproduced signals of the first and second color difference signals from an output reproduced time division multiplexed signal of the comb filter circuit, an encoder for producing a carrier chrominance signal from the output signals of the fourth circuit, and a fifth circuit for producing a reproduced color video signal by multiplexing the carrier chrominance signal and the reproduced luminance signal from the comb filter circuit.
