....(GOP) Picture, Slice,andMacroblock [8] and any of them could be chosen as the unit of work for parallelization. Unfortunately, none of them suffices in itself for decoding ultra high resolution video streams in a PC cluster based tiled display system. In a coarse granularity parallelization [2,9] (e.g. sequence, GOP, picture, or slice) the splitting cost is very low, but the communication cost is high, because decoding servers need to communicate with each other for both referencing previous frames and redistributing decoded pixels. In a fine granularity parallelism (e.g. macroblock ....

A parallel decoder that exploits parallelization at the GOP level in a message passing environment is presented in [7]. This work deals only with MPEG 1 streams. An MPEG 2 video encoder for a LAN of workstations is presented in [11] They conclude that for their approach the best parallel scheme should be based on slices. Work has also been done in designing hardware or combined hardware software codecs that ....
