Videokodierer und -dekodierer mit Verschiebungsverhinderung für korrekt dekodierte Signalblöcke

摘要

A coded data stream with end-of-block (EOB) words is divided into groups each having n EOB words so that loss of an EOB word can be determined at the receiver. When such loss is determined, EOB word(s) is or are inserted locally at the receiver to prevent shift of correctly decoded blocks relative to their true position in the image to be reconstructed.
