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.
Claims4
A dropout correcting apparatus comprising:
- a dropout detecting circuit for detecting a dropout from a reproduced RF signal or a reproduced video signal and generating a dropout detecting flag signal in response thereto;
- a mixing circuit for superimposing said dropout detecting flag signal upon said reproduced video signal to produce a mixed signal;
- a time base fluctuation correcting circuit for removing a jitter component of said mixed signal to produce a time base corrected output signal;
- a dropout detecting flag signal separating circuit for separating said dropout detecting flag signal from said time base corrected output signal;
- and
- a dropout correcting circuit which corrects a dropout of said time base corrected output signal in response to said separated dropout detecting flag signal.
