Abstract: A video stream encoding apparatus and method therefore is herein described. The video stream encoding apparatus includes a divider for dividing a frame in a video stream into a plurality of processing units, each processing unit including a plurality of macro-blocks; and an encoder for encoding the plurality of macro-blocks in each processing unit in parallel.
