Derivation and use of motion vectors in a differential pulse code modulation system. |
| 摘要 |
<p>A differential pulse code modulation system having bidirectional motion estimation for blocks in B frames that is derived from the motion vector of a block in an anchor frame whose projection along its motion vector has the most overlap with the block in the B frame for which a motion estimation is sought. <IMAGE></p> |
