Abstract
PURPOSE: To prevent pictures from being unstable due to the S/N deteriorated by supplement of signal lack periods, by providing the first switching circuit, which extracts selectively input signals according to a control signal, and the second switching circuit which is connected to the video output terminal and the delay line of an approximately one-horizontal scanning time.
CONSTITUTION: In case of normal dropout, though switching circuit 12 is switched to the B terminal side by the output of OR circuit 30, switching circuit 21 is connected to the A terminal side because no joint pulse is generated, and the reproduced video signal is delayed accurately by the 1H period by 1H delay line 15 and minute delay line 27. Meanwhile, in case of the signal lack period dependent upon joint, switching circuit 12 is switched to the B terminal side, and simultaneously, switching circuit 21 is switched to the B terminal side and the reproduced signal which passed through 1H delay line 15 is applied to low-pass filter 22 and synchronizing separating circuit 24.
