ABSTRACT:
A color video signal recording and reproducing apparatus comprises a first circuit for producing a luminance signal which has or has not been subjected to a time base compression, a second circuit for forming a time base compressed line-sequential color difference signal, a circuit for generating a time-division-multiplexed signal by time-division-multiplexing output signals of the first and second circuits, a circuit for obtaining a frequency modulated signal by frequency-modulating a carrier by a low-frequency component of the time-division-multiplexed signal, a first converter for producing a low-band converted high-frequency time-division-multiplexed signal, a circuit for recording on a recording medium a signal in which at least the output signal of the first converter and the frequency modulated signal are frequency-division-multiplexed and for reproducing the same, a demodulator for obtaining a reproduced low-frequency time-division-multiplexed signal from the reproduced signal, a second converter for obtaining a reproduced high-frequency time-division-multiplexed signal from the reproduced signal, and a circuit for forming a reproduced color video signal which is in conformance with a standard system, from output signals of the demodulator and the second converter.
