METHOD AND APPARATUS FOR ENCODING/DECODING MULTI-CHANNEL AUDIO SIGNAL BY USING A PLURALITY OF VARIABLE LENGTH CODE TABLES

摘要

A method and apparatus for encoding a multi-channel audio signal is provided. The method includes the operations of selecting a first variable length code table (VLC) that is to be used to encode the multi-channel audio signal in a given frequency band, from among a plurality of VLC tables, and encoding the multi-channel audio signal by using the first VLC table. Thus, the multi-channel audio signal can be encoded by using VLC tables that differ according to frequency bands.
