【摘要】 多媒体通信是计算机通信领域的研究热点；是计算机支持协同工作的关键技术，而同步控制是多媒体通信的核心问题之一。结合有限状态机和面向对象方法，给出一种既能很好地表示控制，又能完整描述数据的模型，满足了计算机支持协同工作对多媒体同步通信的要求。更多还原

【Abstract】 Multimedia communication is one of focuses and key issues in computer communications and computer-supported cooperative work respectively, among which, synchronization control is one of core problems. The article combines finite state model and object-oriented method, presents a new model which can express control clearly, as well as describe data fully. It satisfies the demand resulting from the multimedia synchronization communication of computer-supported cooperative work.更多还原
