DATA COMPRESSION SYSTEMS AND METHODS

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 comprising:
a memory; and one or more processors configured to:
receive one or more data blocks;identify one or more attributes of the one or more data blocks;search for recognition information stored on the memory corresponding to the one or more attributes;compress the one or more data blocks according to the corresponding recognition information obtained from the memory to produce one or more encoded data blocks corresponding to the one or more data blocks when recognition information corresponding to the one or more attributes is found in the search of the memory;compress the one or more data blocks with a default lossless compression encoder to produce one or more compressed data blocks when the one or more attributes of the data are not found in the search of the memory; andstore the one or more compressed data blocks and information regarding the one or more attributes of the one or more data blocks in the memory when the one or more attributes of the data are not found in the search of the memory.
