Abstract

PURPOSE: To reduce beat disturbance in reproduction of color video signals on a SECAM system.
CONSTITUTION: Color video signals from terminal 1 are inputted to LPF2 and BPF5 and luminance signals separated from video signals by LPF2 are FM-modulated 3 and then applied to adder 9 after unneeded components are removed 2. Video signals separated by BPF5, on the other hand, are converted into a low frequency by frequency converter 6 by using the output of OSC8 and then applied as a low- frequency conversion color signal to adder 9 through LPF7, and the addition output is supplied to magnetic head 11 by way of amplifier 10. As converter 6, a balanced modulator, for example, is used and when a low-frequency converted chrominance subcarrier frequency is denoted (fc) and a horizontal frequency (fH), (fc) is selected as shown by formula (4) to make beat disturbance between (fc) and 2(fc) inconspicuous, thereby obtaining reproduced screens of high quality.
