Abstract:
1. A method of decompressing one or more compressed data packets of a data stream using a data decompression processor, wherein multiple decoders applying a plurality of lossless decompression techniques are applied to a data packet, the method comprising: receiving a data packet from the data stream having one or more descriptors comprising one or more values, wherein the one or more descriptors indicate lossless encoders used to compress data blocks associated with the data packet, and further wherein the lossless encoders are selected based on analyses of content of the data blocks; analyzing the data packet to identify a descriptor; selecting one or more lossless decoders for a data block associated with the data packet, wherein the selecting is based on the descriptor; decompressing the data block with a selected lossless decoder utilizing content dependent data decompression, if the descriptor indicates the data block is encoded utilizing content dependent data compression; and decompressing the data block with a selected lossless decoder utilizing content independent data decompression, if the descriptor indicates the data block is encoded utilizing content independent data compression.
