ABSTRACT:
A method of enhancing picture quality of a video signal is disclosed. The method comprises the steps of receiving an encoded video signal having a plurality of headers; maintaining a plurality of codebooks based upon the differences between a standard definition picture and a high definition picture; and providing a pointer to a particular codebook of the plurality of codebooks when decoding a frame of the video signal.
