Abstract
A bit coding method modifies the bit-steam information in such a way as to provide a very high compression during lossless symbol coding and may be used as a preprocessor for Huffman and arithmetic encodings or on its own. A bit rearrangement scheme (BRS) improves the run length within a data symbol set and achieves a more efficient data-to-symbol mapping. The BRS is implemented on the data symbol set in a column-by-column fashion. The BRS can be combined with any available lossless coding scheme, providing for a more efficient lossless bit coding scheme (ALBCS).
