Abstract:
An encoding system analyzes a data file to determine if portions of the data file include significant disparities in symbol probability. Huffman coding trees are produced for each of the portions of the data file and the portions are separately encoded according to specific Huffman coding trees. Encoded portions and the corresponding Huffman coding tree are packaged together and transmitted to a decoder. The encoder and decoder processes portions using different Huffman coding trees in parallel via multiple processors or processing cores.
