DATA COMPRESSION SYSTEMS AND METHOD

摘要

Data compression using a combination of content independent data compression and content dependent data compression. In one aspect, a system for compressing data comprises: a processor, and a plurality of data compression encoders wherein at least one data encoder utilizes asymmetric data compression. The processor is configured to determine one or more parameters, attributes, or values of the data within at least a portion of a data block containing either video or audio data, to select one or more data compression encoders from the plurality of data compression encoders based upon the determined one or more parameters, attributes, or values of the data and a throughput of a communications channel, and to perform data compression with the selected one or more data compression encoders on at least the portion of the data block.

1. A system for compressing data comprising:
a memory configured to store one or more data blocks; a counter module configured to determine a size of the one or more data blocks; a recognition module configured to analyze data within the one or more data blocks to identify one or more parameters or attributes of the data; and a plurality of data compression encoders including one or more lossless, dictionary-type encoders and a different encoder; wherein the one or more lossless, dictionary-type encoders are configured to compress the one or more data blocks if the one or more parameters or attributes are recognized, and the different encoder is configured to compress the one or more data blocks if the one or more parameters or attributes are not recognized.
