Demo Paper: A Fast-Adjusting Rate Control Algorithm Using Network-Assisted Scheme for HD Video Streaming

We present the integration of our Dynamic Rate Control (DRC) method with the Network Assisted Dynamic Adaptation (NADA) method, and their deployment in a High Definition Video Conferencing application over best effort networks (Internet). DRC offers the best frame quality at a given bitrate, and also jumps to new video bitrate on the fly, within 2-6 frames, which is much faster than other rate controllers, whereas NADA can detect congestion. By combining DRC with NADA, we have designed a complete solution that maintains the video bitrate according to the available and changing bandwidth quickly and with minimal effect on perceived quality. The demonstration shows that this solution provides a fast, efficient and adaptive video conferencing system.
