Abstract

A system and method for compressing data is disclosed. The system and method include one or more data compression algorithms with at least one data compression algorithm from among the one or more data compression algorithms utilizing an asymmetric data compression. The system and method determine a type of data having one or more parameters, attributes, or values of the data from at least a portion of a data block; select one or more data compression algorithms from among the one or more data compression algorithms based upon the determined type of data and a throughput of a communications channel; and perform data compression with the selected one or more data compression algorithms on at least the portion of the data block.

a processor configured;

to analyze one or more data parameters from one or more data blocks containing video data, wherein at least one data parameter relates to an expected or anticipated throughput of a communications channel; and
