The reference point model is extended by adopting pre-schedule policies to cope with the fine-grained synchronization. Finally, through atomic operation such as waiting, dropping and skipping, etc., this paper guarantees the realization of synchronization maintenance mechanism. 多媒体CAI 服务质量 同步控制 multimedia CAI quality of service synchronization control 10.14188/j.1671-8836.2000.01.012 TP311 国家863计划资助!（863－306－ZT04－01－1） 2000-01-01 2021-04-01 1
