Abstract
A method and apparatus for decompressing compressed data, which includes video data that has been compressed in accordance with the MPEG 2 standard, wherein the processing begins by retrieving components from a non-local memory at a rate that is independent of the rate in which the components were written into the non-local memory. The components include motion vectors and run/level data. As the components are retrieved from memory, the run/level data is used to produce representations of the uncompressed data. As the representations of the uncompressed data are generated, they are processed based on the motion vector data to recapture the uncompressed data. The uncompressed data is then stored in a frame buffer for subsequent display.
