本文提出了一种多媒体通信中存储的连续媒体流的同步输出机制。该方法包括流内同步机制和流间同步机制。流间同步控制在流内同步控制之后进行。然后检查是否继续保持流内同步。该机制可用于具有未知延迟边界的网络，并且它不假设视频帧等媒体单元的周期性生成。它还处理两种类型的媒体流，这取决于同步媒体流的严格程度：紧耦合媒体流和松耦合媒体流。此外，我们增强了支持实时输入媒体流的机制，如电视会议。
This paper proposes a media synchronization mechanism which adjusts the output timing among stored continuous media streams in multimedia communications. The proposed method consists of intra-stream and inter-stream synchronization mechanisms. The inter-stream synchronization control is performed after the intra-stream synchronization control. Then, whether the intra-stream synchronization is still maintained or not is checked. The mechanism con be used in networks which have unknown delay bounds, and it does not suppose periodical generation of media units such as video frames. It also deals with two types of media streams depending on how strictly to synchronize media streams: tightly-coupled media streams and loosely-coupled media streams. Furthermore, we enhance the mechanism to support real-time-inputted media streams as in TV conferencing.
