中文摘要: 针对集群大屏拼接显示系统各节点机独立解码、视频流显示不同步的问题，本文分析了集群拼接显示系统的特点，提出了利用PTS信息实现集群内各节点机同步显示视频流的机制，研究了组播接收模块、TS流拆包模块、视频解码模块和同步控制模块和拼接屏显示模块等视频流同步显示实现技术. 研究试验结果证明了基于PTS的视频流集群同步显示技术的有效性.
Abstract:A PTS Based synchroniztion display technology of video stream is presented to solve asynchronous display problem of node computer in cluster. Features of cluster tiled display system is analysed. Video stream synchronous mechanism based on PTS information is researched, and the implementation of modules, such as multicast receiving, stream unpacking, video decoding, synchronization control, are discussed. The experimental results show that PTS based synchronization display technology of video stream in cluster is effective.
