摘要:
乘客信息系统(简称PIS)通常需要接入广播电视中心的SDI信号,经中心专用的直播系统转换成IP网络流转发到车站和列车进行解码播放。当前,针对PIS系统存在专业化程度较高,故障节点多,进口设备需求适应性差,对维保人员要求较高等痛点,迫切需要研发一套国产化的视频直播系统,以满足更高的视频播出品质及降低维保技术门槛,加快产业推广。本文针对中心专用的直播系统进行了软硬件一体化设计,将多个专用设备和业务功能通过软硬件一体化设计的方式集成为一个设备,物理上减少了80%的故障节点,逻辑上实现了直播补包、节目单推流、双机冗余、通道冗余等多项功能,并实现了产业化应用,取得了良好的应用效果。
Abstract:
The passenger information system(PIS)usually needs to connect to the SDI signal of the broadcasting and television center,which is converted into an IP network stream through the dedicated live broadcast system of the center and forwarded to the station and train for decoding and playback. At present,in view of the high degree of specialization,many fault nodes,poor adaptability to imported equipment of the PIS system,and higher requirements for maintenance personnel, there is an urgent need to develop a domestically produced video live streaming system that adapts to high-quality broadcasting,thus reducing the technical threshold of maintenance,and speeding up industrial promotion. This paper focuses on the integrated design of software and hardware for the dedicated live streaming system in the center,integrating multiple dedicated devices and business functions into one through a software and hardware integration approach,which physically reduces 80% of failure nodes and logically achieves multiple functions as live streaming compensation,program stream push,dual machine redundancy,and channel redundancy,and thus realizing industrial applications,and delivering good application results.
