ABSTRACT:
An encoding method and apparatus for encoding multi-channel signals employed in, for example, a stereo system of a video disc player, a video tape recorder, a motion picture film picture system, or a so-called multi-surround acoustic system. Five channels, namely the center (C) channel, left (L) channel, right (R) channel, left surround (SL) channel and the right surround (SR) channel, for example, are handled in common depending upon frequency characteristic of digital audio signal and the targeted playback environment, and encoding is done while the combinations of the channels to be handled in common are altered. High compression may be achieved with the use of pre-existing encoding and decoding units by handling the channels in common without dependency upon the degree of correlation of multi-channel digital data.
