Abstract

PURPOSE: To prevent the deterioraion of reproduced pictures dependent upon beat interference and jitter by selecting the frequency of beat signals, which give a main interference, so that it may interleave to the synchronizing frequency which luminance signals have.
CONSTITUTION: In case that luminance signals included in color video signals are recorded in th state of frequency-modulated signals, circuit 12 to convert chrominance signal Ss to signal Sc of a prescribed carrier frequency, gate circuit 21 extract burst signals from signal Ss, and circuit 28 to have a prescribed phase or frequency based on the output phase or frequency of circfit 21 and form alternating signal Sk for frequency conversion in circuit 12 are provided to select the carrier frequency of signal Sc so that the higher-harmonic frequency, which gives a main intrference, may interleave to the synchronizing frequency which luminance signal Sy has. Howevre, good-quality pictures can be obtained in the seproducing system by the frequency conversion course opposite to the recording system.
