Feed-forward buffering and rate control based on scene change featureslll FOR MPEG VIDEO CODER

Video traffic management has been a challenging task in the fields of network management and multi-media communication. Transmission buffering is widely used to smooth bursty traffic and maintain a steady traffic level by adapting the incoming source traffic to the buffer. This paper describes an efficient adaptive buffering scheme which is based on feed-forward control to adaptively handle the non-stationary nature of bursty video traffic. The performance of a series of quantisation scale mapping curves is presented in terms of occupancy and video quality.
