Abstract
A parallel H.263 video encoder, which utilises spatial para1 elism,
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 proces!;ed by
a separate processor by computing motion and texture mding
with all processors cach acting on a different part of thc ]mag.
This method leads to a performance increase, which is roughly in
proportion to the number of parallel processors used
