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间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。
Aiming at the problems of large amount of multi-view stereo video data and limited network bandwidth, a multi-view multi-view stereo real-time transmission system for packet transmission is proposed. After multi-view data is compressed and encoded by H.264 / AVC, the system performs packet multiplexing on two IP links to realize the real-time transmission of the stereoscopic video in the network with limited bandwidth. In the meantime, in order to solve the problem that the Packet loss problem, a joint error concealment algorithm for inter-temporal inter-view prediction is proposed. Finally, experiments show that the error concealment algorithm in this paper can improve the decoding quality of multi-view stereo video.
