摘　　要：随着宽带网络飞速发展,网络立体电视将成为未来视频主流业务.提出一种实时纠错的P2P模式网络立体电视播放系统的解决方案,该方案利用P2P技术进行视频传输,利用LDPC码进行纠错.经实验证明,在高斯噪声下,纠错后的立体视频与未纠错的相比,PSNR值平均提高约15dB.通过在CERNET2网络中测试,系统充分保证了立体视频的正常观看,同时系统配备认证功能,并且兼容IPv4和IPv6网络环境,能够为未来网络立体电视产业化发展提供有力支持.With the rapid development of Broad-band network technology,3DTV has become a research hotspot and IP-3DTV is to become a trend.This paper presents a solution to the real-time correction IP-3DTV player system based on P2P network,which adopts P2P and LDPC for video transmission and correction respectively.Experiment shows that with Gaussian noise,the average PSNR value of the corrected video increases by almost 15dB.We test the system in CERNET2,and find that the system runs normally.Meanwhile,the system is implemented with authentication,and can run in both IPV4 and IPV6 network,which provides strong support for the industrialized development of IP-3DTV in the future.
