ABSTRACT:
A data compression method and apparatus for processing a stream of original data samples to produce a compressed data stream that comprises both compressed and not-compressed data samples. The technique includes a data compression means for applying a data compression technique to said original data samples so as to develop a sequence of compressed original samples and not-compressed original samples, and providing the sequence of samples in a data portion of a transmission packet. A compression indicator means is also provided for developing a sequence of bits indicating which of the samples in the compressed data stream are representative of one of the compressed original samples and not-compressed original samples, and providing the sequence of bits in a map portion of the transmission packet. The map portion of the transmission packet is used for rapid identification and decompression of the compressed data. In accordance with a further aspect of the invention, the map portion is also used as an indicator of a characteristic of the original data.
