| Title of Invention | ENCODING AND DECODING A MEDIA SIGNAL |
|---|---|
| Abstract | The invention discloses a method of embedding infonnation for high quality restoration of a media signal (typically an audio-visual signal) in a lower quality version of the signal. To this end, the signal x is encoded using a high quality encoder (Q2). The code sequences z produced by the high quality encoder are mapped into code sequences y that are associated with a hypothetical lower quality encoder (QI). The latter code sequences y are transmitted. A simple decoder will decode the received sequences y, and thus reproduce a low quality version of the signal. A more sophisticated decoder is arranged to inversely map the received code sequences y into the code sequences z, that were actually produced by the high quality encoder (Q2). The sophisticated decoder will thus reproduce a higher quality version of the same signal. |
