ABSTRACT:
A method of encoding compressed data for transmission or storage. The method includes converting the input data stream into a sequence of literal references, history references, and lexicon references. Each literal reference includes a literal identifier. Each history reference includes a history identifier. Each lexicon reference includes a lexicon identifier. The history references and lexicon references specify the location of strings of symbols in a history buffer and lexicon, respectively. The encoding method of the present invention encodes the location information in an optimal manner.
