Method of coding video streams for low-cost multiple description at gateways
The present insertion utilizes a data relationship between B-frame motion vectors (k(B)) and P-frame motion vectors (k(P)) to simplify merging and dividing of multiple descriptions ( 22, 24 ) at network nodes ( 28 ) such as gateways by avoiding the need to decompress and re-compress at least one of...
