ABSTRACT:
The present invention is a low complexity method for reducing the number of motion vectors required for bi-predictive frames or fields in digital video streams. The present invention utilizes the motion vectors located in the corner blocks of a co-located macroblock, rather than all motion vectors, when determining the motion vectors of a current block. This results in reduced resources in the computation of direct motion vectors for a bi-predictive frame or field.
