实时多媒体交互与协作系统中发言权控制的研究

发言权控制(Floor control)是在多媒体交互协作环境中协调、控制并发使用共享资源的技术，是交互与协作系统中一种重要的协调控制机制。本文详细分析了floor control协议及其主要控制策略，介绍了实时多媒体交互协作系统——基于OP通道的人一人交互协作系统，在此基础上提出了实时floor control协议RTFCP，着重对RTFCP及其控制策略进行了详细的讨论。同时，对协议的安全性、实时性、公平性进行了讨论。

Analasis on Floor Control Protocol for Realtime Multimedia Interactive and Co-operative System

Floor control is the technology of coordinating and controlling the shared resources concurrently used in the interactive and co-operative environments. It is an important coordinative controlling mechanism. Based on the discussions of floor control protocol and its control policies, a floor control protocol for real time multimedia interactive and cooperative system (RTFCP) is presented. It makes the transmission delay between FC and other users least by adapting the position of FC and makes the protocol more fairly by its fuzzy control policy. At last, the correctness, fairness, and real-time of the RTFCP are discussed.
