Abstract

PURPOSE:To eliminate unnaturalness by equalizing a television signal to an audio signal in terms of time by delaying the audio signal by the delay time of a television signal processor. CONSTITUTION:A television signal applied to television signal input terminal 1 is supplied to television signal processor 8 and frame-synchronism detector 9 and a processed output signal from output terminal 2 of processor 8 is supplied to frame- synchronism detector 10. Then, detection outputs of both detectors 9 and 10 are inputted to delay time detector 11, which measures the delay time of the input- output frame synchronism of processor 8. Then, an audio input signal applied to audio signal input terminal 3 is delayed by variable delay element 12 as much as the obtained delay time. Namely, the signal, delayed by processor 8, from terminal 2 and that from terminal 4 are outputted with the same delay time. Therefore, a television signal and audio signal relatively free from a delay difference can be obtained, eliminating unnaturalness.
