ABSTRACT:
Apparatus is provided for recording and reproducing video and audio signals on a record medium, wherein the audio signal may be of at least two different types subjected to respectively different types of audio processing. A recording section produces frequency modulated audio signal components and selectively adjusts the level of at least one FM audio signal component during the video blanking intervals as a function of the type of audio signal being modulated. Then, the FM audio signal components and the video signal are combined and recorded. A reproducing section separates the reproduced FM audio signal components from the reproduced video signal and detects the level of at least one separated FM audio signal component during blanking intervals. The FM audio signal components are demodulated and processed pursuant to a selected type of audio processing dependent upon the detected level of the FM audio signal component.
