Abstract

A method and system for reducing the complexity of block motion estimation is described. According to the invention, the block distortion measure is determined by calculating a partial error result using a proportion of pixels in the block, comparing the partial error result with a threshold value and rejecting blocks where the partial error result is greater than the threshold value, and calculating a full error result for non-rejected blocks only. The threshold value is a function of the current minimum partial error result, and is preferably the current minimum partial error result multiplied by a threshold constant λ. Another aspect of the invention provides a video transport scheme which exploits the different importance of both GOP and re-synchronisation levels. According to this aspect, an unequal loss protection (ULP) philosophy is utilized. That is, the bit stream data is partitioned into several parts according to different importance, and the parts are unequally protected against packet loss using forward error correction codes.
