Burstiness minimized rate control for high resolution H.264 video conferencing

In recent times, multimedia traffic constitutes a large portion of Internet traffic. Interactive video exchange system (e.g. video conferencing) requires an efficient real-time rate control scheme to maintain pre-assigned average bandwidth and constant bit rate throughput. In this paper, we propose an efficient low complexity slice level rate control method, suitable for high resolution interactive video conferencing system. The proposed method minimizes instantaneous bit rate fluctuations for variable data rate produced by the encoder. For the proposed rate control scheme, instantaneous rate measurements at every packet sending interval shows that almost 95% of the samples are successfully restricted within 5% of specified rate. The proposed method has been established to be superior to H.264 reference software JM 18.4 in respect of burstiness minimization.
