Abstract

PURPOSE: To realize the reproduction for the excellent image, by providing the phase comparator circuit, the voltage control oscillator circuit and others and thus securing the assured correction to the time base error of the video signal.
CONSTITUTION: Tracking control signal f1 is the continuous signal with the high frequency and thus always compared in the pahse with the oscillation output of reference oscillator circuit 27 at phase comparator circuit 26. And the control is always given to the clock frequency of voltage control oscillator circuit 29 in accordance with the output signal proportional to the phase difference of both signals led out to the output end of circuit 26. Accordingly, the delay time of delay line 30 is always controlled accurately, and an assured correction is given to the time base error of the video signal. As a result, no color shading is caused to the reproduced picture for the vertical period and with no color distortion caused even for the horizontal period. In such way, the excellent video signal can be reproduced.
