ABSTRACT:
A video signal compression system includes motion compensated predictive compression apparatus for compressing respective frames of video signal according to either intraframe processing or interframe processing on a block by block basis to generate blocks of compressed data and associated motion vectors. A compressed signal formatter arranges the blocks of compressed data and the associated motion vectors according to a desired signal protocol wherein motion vectors of interframe processed frames are associated with corresponding blocks of compressed data and motion vectors of intraframe processed frames are associated with blocks substantially adjacent to corresponding blocks of compressed data. The motion vectors are included with intraframe compressed data to facilitate error concealment at respective receiver apparatus.
