ABSTRACT:
A synchronizing apparatus includes an audio signal processing counter which is preset such that 735 or 736 samples of audio data exist in the vertical synchronizing signal of the video signal, such that the video and audio data are synchronized with each other within one field. Wherein a standard video signal is synchronized with the audio signal sampled by the clock and having a sampling frequency different from that of the video signal. In this synchronizing apparatus, audio signal processing counters (12), (14), (19a), (19b), (19) are preset so that 735 or 736 samples of audio data may exist in a vertical synchronizing signal of the standard video signal.
