The scalable extension of H.264, known as scalable video coding (SVC) ha s been the main focus of the oint Video Team’s work and was finalized a t the end of 2007. Synchronization between media is an mportant aspect i n the design of a scalable video streaming system. This paper proposes a n efficient media synchronization mechanism for SVC video transport over IP networks. To support synchronization between video and audio bitstre ams transported over IP networks, a real-time transport protocol/RTP ont rol protocol (RTP/RTCP) suite is usually employed. To provide an efficie nt mechanism for media onization between SVC video and audio, we suggest an efficient RTP packetization mode for inter-layer synchronization wit hin SVC video and propose a computationally efficient RTCP packet proces sing method for inter-media synchronization. By adopting the computation ally simple RTCP packet processing,we do not need to process every RTCP sender report packet for inter-media synchronization. We onstrate the e ffectiveness of theproposed mechanism by comparing its performance with that of the conventional method.
