摘　　要：基于分布式存储的轨道交通车载视频监控系统,针对解码显示终端,本文提出一种新的软件架构。该架构基于海思Hi3531核心板,结合JRTPLIB开源库,引入缓冲区动态调整机制,解决了传统车载视频监控系统出现频率较高的解码花屏等问题。实验结果显示,基于新架构下的解码显示终端较传统车载视频服务器,显示效果良好,长时间测试运行稳定,降低了解码问题出现几率。This paper presents a new software architecture of the decoding terminal in train-borne CCTV system based on distribu- ted storage. The architecture is based on Hisilicon Hi3531 core board, uses JRTPLIB library and buffer dynamic adjustment mechanism, in order to solve the higher frequency problems happened in traditional train-borne CCTV system. The result shows that the decoding terminal based on the new architecture works well and reduces the chance of problems.
