ABSTRACT:
An audio data playback clock signal generating apparatus of a digital VCR synchronizes an audio frame playback synchronization signal with a video frame synchronization signal when an audio data recorded in a magnetic tape is played back based on a phase error of an audio data frame size AF-SIZE and an audio data playback clock signal of the previous video frame. The audio data playback clock signal generating apparatus comprises an audio data frame size decoder, a low pass filter, a voltage-controlled oscillator, and phase error generating block and can be implemented by a large scale integration(LSI) to thereby provide a non-complex circuit and an accurate synchronization between the audio frame playback synchronization signal and the video frame synchronization signal.
