A parallel H.263 video encoder, which utilises spatial parallelism, has been modelled using a multi-threaded program. Spatial parallelism is a technique where an image is subdivided into equal parts (as far as physically possible) and each part is processed by a separate processor by computing motion and texture coding with all processors each acting on a different part of the image. This method leads to a performance increase, which is roughly in proportion to the number of parallel processors used.
