本文对实时媒体（语音和视频）唇同步的单流和多流方法进行了性能比较。前者传输语音和视频交织的单一传输流，而后者将这两种媒体视为独立的传输流。每种方法都有一个不在目标执行同步控制的选项，这导致了四种基本方案。在一个相互连接的atm -无线局域网上，我们实现了四种基本方案：基于UDP的RTP/RTCP和两种对JPEG视频进行动态分辨率控制的变体。通过对六种方案的性能测量，我们对它们进行了比较，以识别和评估每种方案的优缺点。
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.
