ABSTRACT:
A differential pulse code modulation system having bidirectional motion estimation for blocks in bidirectionally-predicted frames, 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.
