Abstract:
A data compression method improves Lempel-Ziv (“LZ”) compression by encoding the offsets produced during LZ compression as variable-bit-length (“VBL”) encoded integers, and outputting the VBL integers as part of the compressed data. Other integers produced during LZ compression, as well as integers produced by other data compression algorithms, can also be encoded using a VBL scheme.
