本文提出了基于Mbone/Internet的多播流间同步的第一个实现。可变比特率视频、带沉默抑制的分组音频和不可预测的Mbone流量特性为设计提供了真正的考验。本文还描述了一种高效的新型视频工具架构,用于提供流内同步,并使用本地会议总线实现流间同步。主观性能测试结果表明,该算法的有效实现足以为多媒体会议应用提供唇同步。
This paper presents the first implementation of multicast interstream synchronisation over the Mbone/Internet. Variable bit-rate video, packet audio with silence supression and the unpredictable Mbone traffic characteristics provide a real test for the design. The paper also describes an efficient novel video tool architecture to provide intra-stream synchronisation, and implementation of interstream synchronisation using a local conference bus. Subjective performance results indicate that the efficient implementation is good enough to provide lip synchronisation for multimedia conferencing applications.
