Paper Abstract

Variable bit rate transmission opens the way to constant quality video coding. However, this requires a different approach from the traditional constant bit rate coding techniques since a constant distortion does not yield a constant quality. We introduce a method to determine the maximum distortion locally, and a technique to minimize the bit rate regarding this local maximum distortion. Also, it is shown that with bit stream shaping and peak bit rate control the bit rate will always be lower than in a CBR source with similar quality in the most difficult scenes.
