PCT No. PCT/NO95/00172 Sec. 371 Date Jun. 5, 1997 Sec. 102(e) Date Jun. 5, 1997 PCT Filed Sep. 27, 1995 PCT Pub. No. WO96/10316 PCT Pub. Date Apr. 4, 1996In a digital picture video signal compression encoding process for transmitting such signals via a narrowband transmission medium, two or more pictures are co-encoded by encoding/decoding blocks having the same picture position, together. First, the block of the last picture is encoded/decoded, and thereafter the decoded result in this block is used as a prediction for the remaining blocks, together with information from previously decoded pictures. Preferably one single shift/movement vector is used in order to indicate a prediction for several blocks. In addition, transform coefficients representing difference signals to be transmitted, are interwoven from the blocks to be co-encoded, so that the transmission format for transforming coefficients will be the same as when encoding/decoding one block. |
