Application solution of video streaming server for metro passenger information system
-
摘要: 随着地铁乘客信息系统（PIS）对中心视频播出要求的提高，既有的视频流服务器已不能满足要求，同时也为了提高系统的国产化率，迫切需要研发具有自主知识产权的视频流服务器。文章从地铁视频播出的需求出发，分析现阶段地铁的发展现状，提出一套更适合地铁运营的视频播出方案。采用该方案的多通道视频流服务器已在国内多条地铁PIS中成功应用，并取得良好的应用效果。Abstract: With the improvement of the requirement of central video broadcasting for metro passenger information system(PIS), the existing video streaming server cannot meet the requirements of metro PIS video broadcasting, meanwhile, in order to improve the localization rate of the system, it is an urgent to develop a video streaming server with independent intellectual property rights. Starting from the demand of metro video broadcasting, this article analyzed the current situation of the development of the metro, and put forward a set of video broadcasting scheme which was more suitable for metro operation. The multi-channel video streaming server using this scheme has been successfully applied in many metro PIS in China, and has achieved good results.
