Abstract
A video system for coding a stream of video data that includes a stream of video frames divides each video frame into a matrix of a plurality of subblocks, wherein each subblock includes a plurality of pixels. The video system operates in accordance with nine prediction modes. Each prediction mode determines a prediction mode according to which a present subblock is to be coded. One of the nine prediction modes is selected to encode the present subblock, wherein the selected prediction mode provides for a minimum error value in the present subblock.

A method of coding a stream of video data including a stream of video frames, comprising:
- dividing each video frame into a matrix of a plurality of subblocks, wherein each subblock includes a plurality of pixels;
- defining nine prediction modes, each prediction mode determining a mode according to which a present subblock is to be coded;
- and
- selecting one of the nine prediction modes to encode the present subblock, the selected prediction mode providing for a minimum error value in the present subblock.
A video system for coding and decoding a stream of video data that includes a stream of video frames, comprising:
- a video encoder configured to receive a stream of video data including a stream of video frames and to divide each video frame into a matrix of a plurality of subblocks, wherein each subblock includes a plurality of pixels;
- and
- a mode selector in communication with the video encoder, the mode selector configured to define nine prediction modes, each prediction mode determining a mode according to which a present subblock is to be coded, and configured to select one of the nine prediction modes to encode the present subblock, the selected prediction mode providing for a minimum error value in the present subblock.
