  • Patent number: 7751483
    Abstract: A video codec that allows for improved performance of embedded devices using vector quantization and the high correlation between frames in a scene to reduce the overhead associated with displaying video data. Video coding includes determining scene changes in a movie, producing one codebook for each scene, and coding each frame within a scene with the same codebook. The quantized video data is then losslessly compressed and formed into a video stream. Video decoding includes decoding the codebook for a frame and supplying the codebook and frame indices for frame rendering. Alternatively, video coding also includes dividing CPU time between codebook processing, indices processing, and frame rendering to ensure smooth video output.
