Abstract
Apparatus, systems and methods for using the selection of an appropriate parameter at decompression are disclosed. In particular, when adaptive block size discrete cosine transform compression is used to compress data, different combinations of sub-blocks can be generated. To decompress the different combinations of sub-blocks, the appropriate parameter is selected based on block size assignment information and the address of data in the data block.
