Abstract
Data compression/decompression apparatus and methods are provided which exhibit significant data compression improvement over prior art methods and apparatus. This is achieved by providing an adaptive characteristic in which a pair of data compression/decompression translation tables are constructed based on the data which is to be compressed or decompressed. One table is used to compress or decompress while the other is being rebuilt, thus reflecting the characteristics of the most recent input data.
