Abstract
A video signal recording and reproducing apparatus comprises a circuit for separating a luminance and carrier chrominance signals from a color video signal and for recording on and reproducing from a recording medium a multiplexed signal in which a frequency modulated luminance signal and a frequency converted carrier chrominance signal which is frequency-converted into a low frequency band are multiplexed, a circuit for obtaining a reproduced luminance signal, a circuit for obtaining a reproduced carrier chrominance signal which is in an original frequency band and has an original phase by subjecting a reproduced frequency converted carrier chrominance signal to a signal processing, a de-emphasis circuit supplied with the reproduced luminance signal and/or an input signal or the reproduced carrier chrominance signal of the processing circuit, for relatively attenuating the level of a high-frequency component in a temporal frequency of the reproduced luminance signal and/or an input signal or the reproduced carrier chrominance signal of the processing circuit compared to a low-frequency component, and a mixer for mixing the reproduced luminance signal and the reproduced carrier chrominance signal so as to produce a reproduced color video signal.
