Abstract

PURPOSE: To remove a cross-talk component of an adjacent track by frequency-converting 1st and 2nd chroma signals in the same order of a line array, by mixing them into the low band of a FM-modulated luminance signal before recording, and by using a 2H delay line in reproduction mode.
CONSTITUTION: The recording system of VTR consists of chroma signal recording system CR composed of BPF10, phase equalizing circuit 30, color-sequence arrangement circuit 40, frequency converter circuit 50, etc., and luminance signal recording system YR. In circuit 30 of the recording system CR, an unmodulated-signal carrier on the horizontal back porch of a SECAM signal is delayed by 2H by a delay line and detected by being added to an undelayed output, and a phase correction is brought under control by the output to equalize the phase of the sub-carrier of the chroma signal. Then, circuit 40 and 50 equalize sequences of line arrays of 1st and 2nd chroma signals and frequency conversion is carried out by using a frequency obtained by alternatively adding and subtracting a frequency of 1/8fH (fH: horizontal frequency), so that the recording system YR will record them by mixing them into the low band of a FM-modulated luminance signal.
