ABSTRACT:
In a method of compressing a data sequence, the data sequence is parsed into data segments, where at least one of the data segments includes a match. In addition, the match is compressed using at least one context model that depends upon one or more coded data symbols that are available to a decoder. An encoder includes a coding unit configured to code at least one of a match offset and a match length of a data segment using one or more context models that depend on previously decodeable data symbols. A computer readable storage medium having a computer program for implementing the method of compressing the data sequence.
