摘要
VOD教学系统中各媒体流同步和VOD服务器群是设计和实现的主要难点。通过对基于流式传输的三分屏VOD课件中多媒体同步原理和VOD服务器方案的研究,给出了在网络教学环境下各媒体流实现同步的解决方法和基于校园网的流媒体教学系统VOD服务器群集方案,最后给出了具体实现案例。
The major difficulties in VOD teaching system lie in the synchronization of media and VOD servers. The principle of multimedia synchronization and the design of VOD server assemb- ling are studied in this paper for three-division screen VOD courseware based on streaming transmission. Solutions are given to achieve synchronization of media flow in the environment of teaching network, and a scheme of VOD server assembling is designed in the streaming media teaching system based on campus net. Finally, a concrete case of system realization is provided,
