ABSTRACT:
A recording and reproducing apparatus for recording a carrier chrominance signal, comprises a separating circuit for separating a carrier chrominance signal from a color video signal, a recording signal processing circuit for converting the carrier chrominance signal into a carrier chrominance signal having a signal format suited for recording and reproduction, a recording circuit for recording an output signal of the recording signal processing circuit on a recording medium, a reproducing circuit for reproducing the recorded signal from the recording medium, a reproduced signal processing circuit for converting the reproduced signal from the reproducing circuit into a reproduced carrier chrominance signal having an original signal format, and a de-emphasis circuit responsive to the reproduced carrier chrominance signal from the reproduced signal processing circuit, for subjecting the reproduced carrier chrominance signal to a de-emphasis so that a high-frequency component in a vertical spatial frequency of the reproduced carrier chrominance signal is relatively attenuated compared to a low-frequency component of the reproduced carrier chrominance signal.
