ABSTRACT:
Time base fluctuation of a video signal reproduced from a video disc or tape is detected and corrected. Meanwhile, a dropout of such reproduced video signal is also detected. The dropout detection signal thus obtained represents the dropout period during which the time base information is erroneous. Therefore the time base information detected during such dropout period is rendered invalid to consequently eliminate erroneous correction of the time base fluctuation.
