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.
Claims22
A method of enhancing picture quality of a video signal, said method comprising 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;
- providing a pointer to a particular codebook of said plurality of codebooks when decoding a frame of said encoded video signal;
- and
- decoding at least part of the encoded video signal based on the pointer.
A method of enhancing picture quality of a video signal, said method comprising the steps of:
- receiving an encoded video signal having a plurality of headers;
- receiving a plurality of codebook numbers with said encoded video signal;
- maintaining a plurality of codebooks based upon the differences between a standard definition picture and a high definition picture;
- providing a pointer to a particular codebook of said plurality of codebooks;
- and
- decoding a frame of said encoded video signal based on the pointer.
A method of enhancing picture quality of a video signal, said method comprising 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;
- providing a first pointer to a first codebook when decoding a strip of said encoded video signal;
- providing a second pointer to a second codebook when decoding said strip of said encoded video signal;
- and
- decoding said strip of said encoded video signal based on said first or said second pointers.
A method of enhancing picture quality of a video signal, said method comprising the steps of:
- receiving an encoded video signal having a plurality of headers comprising a current enhancement picture, a picture number and at least one codebook number to be applied to a scene;
- maintaining a plurality of codebooks based upon the differences between a standard definition picture and a high definition picture;
- providing a first pointer to a first codebook when decoding a first predetermined block of a strip of said encoded video signal;
- providing a second pointer to a second codebook when decoding a second predetermined block of said strip of said encoded video signal;
- decoding said first predetermined block of a strip of said encoded video signal based on said first pointer;
- and
- decoding said second predetermined block of said strip of said encoded video signal based on said second pointer.
A method of enhancing picture quality of a video signal, said method comprising the steps of:
- partitioning a codebook on a regional basis;
- receiving an encoded video signal having a plurality of headers;
- maintaining a plurality of codebooks based upon said differences based upon the differences between a standard definition picture and a high definition picture;
- providing a pointer to a particular codebook when decoding a frame of said encoded video signal;
- and
- decoding the frame of said encoded video signal based on the pointer.

- receiving an encoded video signal having a plurality of headers comprising a current enhancement picture, a picture number and a plurality of codebook numbers to be applied to a scene;
- maintaining a plurality of codebooks based upon said differences based upon the differences between a standard definition picture and a high definition picture;
- providing a plurality of pointers to said plurality of codebooks;
- and
- decoding a frame of said video signal by applying said plurality of codebooks to a particular scene.
