MOTION VECTOR PROCESSOR FOR COMPRESSING VIDEO SIGNAL

摘要

A video signal compressor includes apparatus for generating motion vectors for respective blocks of video data. Ones of the motion vectors (other than those which provide direction to co-located blocks in other frames) are determined to be candidates to conversion to vectors which do provide direction to co-located blocks. However, conversion is precluded if the vector is determined to be correlated with one of the neighboring motion vectors.
