Video signal recording and reproducing apparatus with a comb filter for removing chrominance components

摘要

A video signal recording and playback apparatus in which in a record mode operation a frequency-modulated luminance signal and a carrier chrominance signal whose frequency has been converted to a one lower than that of the luminance signal are written superposed on each other in a magnetic recording medium and, in a playback mode operation, the signal read out of the recording medium is separated into a reproduced color signal and a reproduced luminance signal, then the two reproduced signals are subjected to predetermined signal processing by individual signal processing systems, and then the processed signals are mixed by a mixer to produce a reproduced color video signal. The mixer to which the reproduced luminance signal is applied is preceded by a comb filter which is operable using a chrominance subcarrier frequency of the reproduced chrominance signal as a reference.
