The method of claim 19, further comprising outputting said data block in uncompressed form, wherein no data type is identified for said data block.

The method of claim 19, further comprising associating a desirability factor to said second lossy encoder.

A method comprising: analyzing a data block to identify a data type of said data block from a plurality of data types; selecting resolution parameters; associating a lossy compression encoder to a first one of said plurality of data types; associating a lossless compression encoder to a second one of said plurality of data types; performing a first data compression, wherein said first data compression comprises compressing said data block with said lossy compression encoder if said data type is identified as said first one of said plurality of data types, wherein said lossy compression encoder compresses said data block at said selected resolution parameters; and performing a second data compression, wherein said second data compression comprises compressing said data block with said lossless compression encoder if said data type is identified as said second one of said plurality of data types. view more

The method of claim 42, further comprising outputting said data block in uncompressed form, wherein no data type is identified for said data block.

The method of claim 42, further comprising associating a desirability factor to said lossless encoder.

The system of claim 1, wherein said first compression technique includes compressing with a plurality of encoders in a parallel configuration and each one of said plurality of encoders is an identical type of encoder.

The system of claim 1, wherein said data stream comprises a collection of multiple files.

The system of claim 1, wherein said data stream includes a third data block and a fourth data block and said compressed data stream is provided by compressing said third data block with a third compression technique and compressing said fourth data block with a fourth compression technique. view more
