TRANSCODING BETWEEN THE INDICES OF MULTIPULSE DICTIONARIES USED FOR CODING IN DIGITAL SIGNAL COMPRESSION
The invention relates to compressive transcoding between pulse coders using multipulse dictionaries in which each pulse occupies a position marked by an index. For each current pulse position supplied by a first coder, a neighborhood (Vge, Vde) is formed around that position. As a function of the pu...

| description | The invention relates to compressive transcoding between pulse coders using multipulse dictionaries in which each pulse occupies a position marked by an index. For each current pulse position supplied by a first coder, a neighborhood (Vge, Vde) is formed around that position. As a function of the pulse positions accepted by the second coder, pulse positions are selected in an ensemble constituted by a union of the neighborhoods. The second coder finally receives this selection (sj), involving a number of pulse positions smaller than the total number of pulse positions in the dictionary of the second coder. |
