Entropy coding alternatives
Two alternative entropy coding procedures are specified: Huffman coding and arithmetic coding. Huffman coding
procedures use Huffman tables, determined by one of the table specifications shown in Figures 1 and 2. Arithmetic coding
procedures use arithmetic coding conditioning tables, which may also be determined by a table specification. No default
values for Huffman tables are specified, so that applications may choose tables appropriate for their own environments.
Default tables are defined for the arithmetic coding conditioning.
