Abstract
The present disclosure is directed to systems and methods for providing fast and efficient data compression using a combination of content dependent, content estimation, and content independent data compression. In one aspect of the disclosure a method for compressing data comprises the steps of: analyzing a data block of an input data stream to identify a data type of the data block, the input data stream comprising a plurality of disparate data types; performing content dependent data compression on the data block, if the data type of the data block is identified; performing content estimation data compression if the content is estimable; and performing content independent data compression on the data block, if the data type of the data block is not identified or estimable. In another aspect of the present invention LZDR compression is applied to simultaneously perform one method of compression while computing statistics useful in estimating the optimal form of compression to be applied.
