ABSTRACT:
A method and apparatus for transmitting and resynchronizing audio and video signals characterized by the encoding of audio timing signals on the video signal prior to transmission, and the decoding of the audio timing signals from the video signal after transmission. The decoded audio timing signals are compared to timing signals generated from the transmitted audio signal, and a delay factor is generated to represent the relative delay between the transmitted audio signal and the transmitted video signal. Either the transmitted video signal or the transmitted audio signal is then delayed by the amount of the delay factor to resynchronize the two signals.
