基于大学课堂的网络流媒体系统的设计

The design of network streaming media system based on college class-teaching

随着信息时代的普及,网络流媒体在大学课堂教学中日益发挥着其重要性。为了整合教学资源,激励学生主动学习的热情,提出一种基于大学课堂的网络流媒体系统的设计方案。该系统结合VPR录播设备、SQL Server数据库、Live555流媒体服务器、VC/MFC界面库等技术,基于C/S架构设计并搭建简单友好的系统客户端和系统管理中心,同时将视频采集门户所采集的视频资源安全完整地上传在服务器软件系统,从而实现网络流媒体直播和点播的大学课堂系统。由于所提出的整体解决方案采用较为先进的技术,并且进行了前期的需求分析准备,因此该设计系统具有良好的可扩展性和可移植性,直播过程能满足实时性要求。

With the popularity of the Information era, the network streaming media plays an important role in college class-teaching.ln order to integrate all kinds of teaching resources and motivate students＇ initiative enthusiasm of study, a design scheme of network streaming media system based on college class-teaching was proposed.Combined with VPR recorded equipment, SQL Server database, Live555 streaming media server and VC/MFC interface library, the system designed and built a simple friendly client system and management system on the basis of Client/Server architecture.Meanwhile, the video resources collected by the video-capture system were uploaded on the server system completely.So that the college class-teaching system could realize the live telecast and video on demand through network streaming media.With the advanced technology and fully preparation on demand analysis, thus the system has a better extensibility and portability, and meet the real-time requirement during the live process.
