ABSTRACT:
A color video signal recording and reproducing apparatus comprises a first circuit for generating a low-frequency luminance signal, a second circuit for forming a time base compressed line-sequential color difference signal, a circuit for generating a time-division-multiplexed signal in which the output signals of the first and second circuits are multiplexed in time-sequence, a modulator for frequency-modulating a carrier by the time-division-multiplexed signal, a first converter for generating a low-band converted high-frequency luminance signal, a circuit for recording a frequency-division-multiplexed signal of at least the output signals of the modulator and the first converter on a recording medium and reproducing the same from the recording medium, a second converter for obtaining a reproduced high-frequency luminance signal from the reproduced signal, a circuit for obtaining a reproduced luminance signal from the reproduced high-frequency luminance signal and a reproduced low-frequency luminance signal obtained from the reproduced signal, and a circuit for obtaining a reproduced color video signal by mixing a reproduced carrier chrominance signal which is obtained from the time base compressed line-sequential color difference signal and the reproduced luminance signal.
