本文提出了一种组播通信中存储媒体的组同步机制，该机制将从目的地与主目的地同步。在主、从端，采用作者提出的流内、流间同步机制，实现主、从端媒体流的同步输出。我们通过调整主媒体流在每个从目的地的输出定时到主目的地来实现组同步。我们还处理通过媒体缩放和控制加入一个正在进行的多播组的流量控制。此外，本文提出了使用ATM网络的实验结果。仿真结果表明了该机制的有效性，并说明了参数对系统性能的影响。
This paper proposes a group synchronization mechanism, which synchronizes slave destinations with the master destination, for stored media in multicast communications. At the master and slave destinations, intra-stream and inter-stream synchronization mechanisms which were proposed by the authors are employed to output the master media stream and slave media streams synchronously. We achieve group synchronization by adjusting the output timing of the master media stream at each slave destination to that at the master destination. We also deal with traffic control by media scaling and control of joining an in-progress multicast group. Furthermore, the paper presents experimental results using an ATM network. It shows the validity of the mechanism and illustrates the influence of parameters on the system performance.
