Abstract (en)

[origin: WO2007050018A1] The invention concerns a novel method for lossless data compression of a sequence of elements. The method comprises the steps of transforming the original sequence of data elements into a new sequence of symbols representing one of a literal element, a backward reference to a previously occurring subsequence of elements, or a table reference to a subsequence in one or more tables of frequently occurring subsequences of elements, and encoding the new sequence of symbols into a uniquely decodeable bit stream for compressing the original sequence.
