摘要
提出了一种基于混合模式的流媒体网络教学系统的设计方案.该方案将C/S模式和P2P模式相结合,有效避免了网络多用户状态的瓶颈问题,利用了H.264图像压缩算法和G.729的音频压缩技术,保障了媒体数据的高质量传输与还原,采用RTP/RTCP协议,解决了视音频数据连续性差、同步性低和数据丢包率高等关键问题.经实验证明该方案满足目前高校网络教学的要求.
This paper gives a design plan about the teaching system of current media network based on the mixed pattern. The plan combines C/S pattern and P2P pattern, effectively avoids the bottleneck in the state of net work multi-users, makes full use of the calculation of H.264 image compression and the technology of G.729 audio frequency compression so as to guarantee the top qualified transmission and reduction of media data. By adopting RTP/RTCP agreement, it solves the key problems such as bad continuity,inferior synchronization and high-rate pack missing of video and audio frequency data, etc network teaching in universities and colleges. By experiments, it proves that the plan can meet the need of
