摘要
针对目前多媒体教室的资源不能被远程教育的学生有效利用的现象,结合音频、视频和屏幕图像压缩算法的压缩比率不断提高的特点,提出了一种多媒体直播课堂软件系统,给出了其系统框架,并详细介绍了该系统的Web服务器、编码服务器、直播服务器、流媒体代理服务器和客户端的设计。该系统与类似系统相比,不受电子讲稿种类多样性的限制,可适应更多的多媒体压缩算法,在传输效率上也有一定的优势。
This paper presents, in view of the increasing compression radio of audio, video and screen image, a software system of multimedia live streaming classroom to solve inefficient utilization of multimedia classroom for distance learning students, gives its system framework, and introduces in detail the design of its modules including web server, encoding server, live streaming server, streaming media proxy server and client. By the comparisons with similar works, the advantages of the system in terms of fitness for diversity of electrical lectures, adaptability to multimedia compression algorithms and transport rate are illustrated.
