Abstract

PURPOSE: To secure the normal automatic adjustment for the color hue by giving the signal process to the signal which is contained in the color video signal and does not pass through the comb-line filter at least for the VIR signal period.
CONSTITUTION: The signal reproduced through record/reproduction system is made pass through HPF12 and FM demodulator 13 to be demodulted to the original luminance signal and then to be supplied to counter circuit 14 and adder 15. On the other hand, the reproduced signal from system 11 is suplied also the LPF17 to be changed to the low conversion carrier chrominance signal, and then undergoes the frequency conversion to the original carrier chrominance signal by the output of oscillator 19 and via balanced modulator 18. Then the unnecessary frequency components and the noise componet are removed through BPF20 and filter 21, and thus the chrominance signal is supplied to adder 15 via the B terminal of switch circuit 22. Circuit 22 transmits the signal of the A terminal given from BPF20 to adder 15 when the pulse signal from circuit 14 is in the higher order and transmits the B terminal signal to 15 when the pulse signal is in the lower order respectively. As a result, the VIR signal is never distrubed by the comb-line filter, thus ensuring the normal automatic adjustment for the color hue. 10,2-Low-pass filter 3-Delay circuit 4-FM modulator 5-High-pass filter 7-Band pass filter 8-Balanced modulator 9-Oscillator 21-comb type filter
