METHODS AND APPARATUSES FOR CODING OF CHANNELS IN PARAMETRIC MULTI-CHANNEL CODING SYSTEM

摘要

The invention relates to a method in parametric multi-channel Coding system for encoding a multi-channel audio signal having a plurality of audio input channels, characterized by comprising : applying a parametric audio encoding technique to generate parametric audio codes for a first subset of the audio input channels for a first frequency region; and applying the parametric audio encoding technique to generate parametric audio for a second subset of the audio input channels for a second frequency region, wherein: the second frequency region is different from the first frequency region; and the second subset is different from the subset.
