ABSTRACT:
An audio signal discrimination apparatus for use in a recording and reproducing apparatus, in which an identification code is inserted into a video signal and a mode of audio signal is discriminated. The audio signal discrimination apparatus includes a sync separator for separating a horizontal sync signal and a vertical sync signal from the video signal, an identification code insertion circuit for receiving the separated horizontal and vertical sync signals so as to insert an identification code for discriminating a processing mode of the audio signal into a predetermined region of the video signal when recording, and an identification code detection circuit for detecting the identification code inserted into the predetermined region of the video signal so as to determine the processing mode of the audio signal. Thus, during the reproducing procedure, the reliability of detection with respect to the audio signal can be enhanced, and the identification of the recording mode of the audio signal can be obtained more quickly.
