METHOD AND APPARATUS FOR ENCODING/DECODING MEDIA SIGNAL

摘要

A method and apparatus for encoding/decoding a media signal. The method of decoding a media signal includes extracting first table index information from a header. The first table index information indicates M (M<N) tables substantially referred to by frames from among N tables which can be referred to for performing an operation performed by the frames, wherein N and M are natural numbers. Second table index information is then extracted from each frame. The second table index information indicates tables referred to by each frame from among M tables. The tables, which are referred to by the frames, are then identified by using the first and second table index information and the frames are decoded by referring to identified tables.
