ABSTRACT:
A dropout correcting apparatus has a dropout detecting circuit for detecting a dropout from a reproduced video signal. A mixing circuit superimposes a dropout detecting flag signal from the dropout detecting circuit upon the reproduced video signal. A time base fluctuation correcting circuit removes a jitter component of an output signal from the mixing circuit. A dropout detecting signal separating circuit separates the dropout detecting flag signal from the output signal of the time base fluctuation correcting circuit, and a dropout correcting circuit corrects the dropout of the reproduced video signal in response to the separated dropout detecting flag signal.
