Abstract :
This paper presents a performance comparison between the single-stream and the multi-stream approaches for lip synchronization of live media (voice and video). The former transmits a single transport stream of interleaved voice and video, while the latter treats the two media as separate transport streams. Each approach has an option not to exert the synchronization control at the destination, which leads to four basic schemes. On an interconnected ATM-wireless LAN, we implemented the four basic schemes with RTP/RTCP on top of UDP and two variants which exercise dynamic resolution control of JPEG video. By the performance measurement of the six schemes, we compare them to identify and evaluate the advantages and disadvantages of each approach
