基于IPv6的校园网视频直播回看系统设计
首发时间:2018-06-04
摘要:针对校园网内观看高清视频节目效率低的问题,设计一套基于校园网环境的视频直播及回看系统,以高效地实现视频播放服务.考虑到原有的系统架构无法与新需求相适应,首先提出了一种具有良好扩展性的视频直播回看系统的系统架构;随着多校区联合部署的分布式媒体部署方案的提出,校区间网络链路压力大幅度减小.本文提出了无需二次转码即可录制直播节目的方法,解决了音视频不同步等问题;为了提高用户体验,系统实现了排行榜、动态截图、点播等功能.实验结果表明,系统单机最大能力可达20Gbps,具有兼容当前主流播放设备功能,可为校内各种教学和活动的视频直播与回放提供技术支持.

Design of IPTV and Catch-up system in Campus network based on IPv6
Abstract:In this paper, aiming at inefficiently watching high-definition live IPTV and catch-up in the campus network, a set of the system is proposed for users to watch videos efficiently. Given that the old system architecture cannot adapt to new usage requirements, the new system architecture having good extensibility is built in this paper. We propose the deployment plan of distributed media among multiple campuses and the transmission pressure of network links between campuses become less. The system needn\'t to secondary transcoding for recording live video and the problem that video and audio are not synchronized is solved. For improving the user experience, the system achieves many functions, such as program rankings, dynamic screenshots and so on. Experimental results show that a computer in this system, having the capability of transmission speed 20Gbps, is compatible with popular playback equipment so that teachers and students can use its services in teaching and school event.
