ABSTRACT:
A CAVLC decoding method and apparatus is provided. In the method for decoding a coded bitstream using a CAVLC length table and a CAVLC value table, CAVLC length tables are re-sorted in an order of a codeword length and the coded bitstream is decoded using the re-sorted length table. Therefore, since data on a bitstream is sequentially read as much as a length suggested by the re-sorted table of the present invention, a memory access time is reduced and calculation complexity for comparing the CAVLC codewords is reduced.
