Vorrichtungen zur Bildkodierung und -Dekodierung mit einer verbesserten Bewegungsvektorkodierungsmethode

摘要

In the video coding and decoding apparatuses, prediction errors and motion vectors are coded in block units even if the motion vectors suffer from transmission error while they are being coded, without damaging other blocks whose motion vectors have been successfully coded. As a result, image deterioration resulted from a transmission error can be limited within a block whose motion vector suffers from the transmission error.
