P2P模式网络立体电视系统设计与实现
摘要
随着计算机网络技术的不断发展,当今基于计算机网络的应用程序越来越多。人们在互联网中可以进行网络远程教育,可以在网络游戏对战平台上玩游戏,也可以通过网络收看电影和电视节目。而且随着立体电视技术的不断发展,基于立体电视技术的产品越来越多,目前很多生产厂商已经开始生产适合播放立体电视的手机,电脑和电视机等,而且越来越多的电影厂商在推出传统平面电影的同时,也推出相应电影的3D版本。目前IPTV已经十分流行,人们可以通过计算机利用网络收看平面视频,但是目前人们还无法通过计算机或者其他终端通过网络收看立体视频。为了解决这个问题,本文提出了P2P模式网络立体电视系统的解决方案。
立体视频也是流媒体的一种,本文在设计系统时,在网络中传输和控制立体视频主要结合目前常用的流媒体相关的RTP,RTCP,RTSP协议。同时考虑到服务器和客户端的直传模式已经不在适应当今的网络传输,本文在设计系统时,采用了P2P网络传输立体视频数据,有效的实现了服务器的负载均衡,有效的利用了网络带宽。同时针对立体视频的相关特性,在客户端系统中设计了相应的纠错,这样就可以保证立体视频在网络较差的时候同样可以正常的播放。
最终,基于如上设计方案,实现了P2P模式网络立体电视系统,通过该系统可以通过网络正常的观看立体视频。实验测试表明,利用P2P模式UDP协议对客户端进行视频传输的速率可以达到5.3MB/s,并且在网络状态较差时,也满足基本的播放功能。
As the development of computer network technique, there are more and more applications based on computer network. Through Internet, People can use Distance Education Network, play computer game on the Internet Game Battle Platform, and watch movie and TV. And as the development of 3DTV technique, there are more and more product using 3DTV technique. Now more and more companies manufacture mobile phone, computer and television which is fit for playing 3DTV, and more and more movie makers design 3D vision of movie when design the normal vision of it. Now IPTV is very popular, and people can watch 2DTV through network, but cannot watch 3DTV using computer or other terminals through network. In order to solve this problem, this paper provides the solution of network 3DTV system based on P2P model.
3DTV is a kind of streaming media, when designing this system, the transmission and controlment of 3DTV is combined with the RTP, RTCP and RTSP, which are popular streaming video protocols. And the method that the client can only receive one server’s data is currently not fit for the network transmission, so in this paper, the system uses P2P network to transmit 3DTV data, which performs payload balance of server and makes use of network bandwidth effectively. In order to utilize the specialization of 3DTV, this paper design error detection in the client system, which guarantees that 3DTV can normal play when the network bandwidth is weaken.
Finally, this paper realizes the network 3DTV system used P2P protocol based on the above solution, and people can watch 3DTV through the Internet. Experiment shows that the rate could reach to 5.3MB/s when transmitting media to one client using P2P and UDP protocol, and even the network gets worse, the normal playing function can be provided.
