Abstract

We describe a novel approach to filtering coded video data. MPEG video is filtered to reduce frame rate and bandwidth by dropping coded B-pictures. The choice of B-pictures to be dropped is made based on an 'activity measure' which indicates the amount of motion within the video scene. We present preliminary results which indicate that this method produces a filtered sequence with higher visual quality than a sequence produced by dropping B-pictures at regular intervals.
