局域网环境下的视频点播系统设计

The Design of VOD on The LAN

在局域网环境下,由网络视频服务器的播控系统、记帐计算机中实时记帐系统和各客户机中视频点播系统有机协调组合,构成了实时视频点播系统。系统中采用节目下载播放代替常见的网络播放,克服了节目播放中可能产生的停频现象。播控系统中的优先队列使节目调度更合理。而网络中分布式数据库的一致性处理更使系统可靠性得以极大提高。

Under the LAN, the VOD is composed of the video server sub system, bill computer sub system and client sub system. The system overcomes the phenomena that video sometimes stop in the method of download instead of on NET. The priority queue makes the system better for program attempering. The system dependability be better sure by adopting DDB consistency processing under network.
