Abstract

PURPOSE:To improve color reproduction in special reproduction by performing the angle modulation of a luminance signal and the low frequency conversion of a chrominance signal and also by recording signals so that a shift of the horizontal synchronizing signal on the adjacent track will be a multiple of one horizontal synchronizing signal interval. CONSTITUTION:A reproduced signal obtained from reproducing head 7 is extracted from a luminance signal through high-pass filter 8 and frequency demodulator 10. A color signal is restored to an original chrominance signal through low-pass filter 9 and frequency converter 11. This restored chrominance signal is applied to adder 12 as it is in normal reproduction. In special reproduction for slow motion, still pictures, etc., it is applied to adder 12 by way of 1H delay line 14. The reproduced signal from head 7 is also applied to flip-flop 20 by way of envelope detector 16, pulse generator 17, integrating circuit 18, and inhibiting circuit 19 and used there as a switching signal for change-over unit 21 to apply adder 12 with a 1H delay signal in the special reproduction. Consequently, the deterioration of reproduced- picture quality accompanying track switching is prevented.
