摘要
以实时、分布式为重点 ,介绍了实时分布式协同工作环境的总体结构 ,着重介绍了基于相对位置的乐观锁机制的并发控制策略和协同感知技术 ,其中对实现实时音视频感知的控件技术也进行了介绍。
In this paper,we analyze the structure of the realtime distributed cooperative work environment.The concurrency controlling scheme of optimistic locking mechanism based on relative position and cooperative awareness technology are presented.To improve cooperative awareness, we develop ActiveX components for network realtime video and audio processing and use them to realize realtime video and audio awareness.
