针对多视点立体视频数据量大、网络带宽受限等问题,提出了一种分组传输多路复用的多视点立体视频实时传输系统。系统将多视点数据通过H.264/AVC压缩编码后,在两个IP链路中进行分组复用,实现了立体视频在带宽受限网络中的实时传输;同时,为了解决IP网络传输中的丢包问题,提出一种联合时域视点问预测的错误隐藏算法。最后通过实验表明,本文错误隐藏算法可以提高多视点立体视频的解码质量。
In order to overcome the problem of large volume data and limited network bandwidth in stere- oscopic video transmission,this paper proposes a packet multiplexing real-time multkview video trans- mission system. After compressing the multi-view data with H. 264/AVC, the system multiplexes the packets in two IP links and realizes the real-time transmission of stereoscopic video over the packet loss network. In packet-based video transmission,the packet loss is inevitable which will severely impact the stereoscopic video quality. This paper proposes an error concealment algorithm jointing temporal and in- ter-view prediction. Finally, the experimental results demonstrate that the proposed error concealment al- gorithm can improve the stereoscopic decoding quality greatly.
