Media Synchronization Framework for SVC Video Transport over IP Networks

This paper proposes an efficient media synchronization framework for SVC video transport over IP networks. To support synchronization between SVC video and audio signals transported over IP networks, RTP/RTCP protocol suite is usually employed. To provide a framework for media synchronization, we suggest an efficient RTP packetization mode and propose a computationally simple RTCP packet processing method. With the suggested RTP packetization mode, layer synchronization among scalable layers of the SVC video can be effectively achieved. Also by adopting the computationally simple RTCP packet processing, we do not need to process every RTCP SR packet for inter-media synchronization between video and audio signals.
