摘要
通过分析多媒体视频信号的编解码技术和网络传输技术,采用H.264视频编解码算法和应用层组播机制,基于现有校园物理网络基础上,文章阐述了构建流媒体转发服务的远程多媒体教学系统,与基于传统单播机制的系统相比,提高了多媒体教学视频数据传输的可靠性和效率。
After analyzing the techniques of multimedia video compression and network transmission, a remote muhimedia teaching system based on campus network is proposed by using H.264 video compressing algorithm and applicatiofi-level muhicast mechanism. Compared with the traditional system with unieast content delivery mechanism, the reliability and efficient to transmit multimedia teaching video are improved.
