CODEWORD ADAPTATION FOR VARIABLE LENGTH CODING

摘要

In one example, this disclosure describes a method of codeword adaptation for variable length coding. The method comprises applying a first codeword adaptation scheme to a first group of codewords of a variable length coding (VLC) table to change a mapping of codewords to events in the VLC table; and applying a second codeword adaptation scheme to a second group of codewords of the VLC table to change the mapping of the codewords to the events in the VLC table.
