Abstract :
A novel approach for the parallel implementation of a CCITT H.261 video coding algorithm on a multiprocessor network is presented. One of the prominent bottlenecks of parallel implementation of a video coding algorithm is the sequential operation of the bit rate control in the coding algorithm. An a priori buffer-fullness estimator is proposed to circumvent this sequential operation which involves changing the quantisation step-size at fixed intervals.<>
