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 the broadband network, the network stereoscopic television will become the mainstream business of the future video.A solution of real-time error correction P2P network stereoscopic television broadcasting system is proposed, which uses P2P technology for video transmission and uses the LDPC code for error correction The experimental results show that the average corrected PSNR value of the corrected stereo video is about 15 dB higher than that of the uncorrected error under Gaussian noise.The system fully guarantees the normal viewing of the stereoscopic video by testing in the CERNET2 network, Equipped with authentication function, and compatible with IPv4 and IPv6 network environment, can provide strong support for the future development of industrial network stereoscopic TV.
