摘要
视讯综合应用平台是以视频监控、视讯会议、远程教育、事故抢险为主要功能的综合业务系统,采用基于TDMA的网络通信方案是本系统的主要特点。文章在深入研究TDMA技术的基础上,讨论了此方案的优点与必要性,并介绍了实现网络信道的动态时隙分配、设备控制、远程视频传输的方案,给出了相应的算法举例。该产品在铁路、高速公路、长途客运均有广泛的应用前景。
Video-communication integrated application platform is an integrated service system. Its principal function includes video-monitoring, video-conference, distance-education and emergency-repairing, and main feature is the TDMA-based network communication scheme. Based on the in depth study of TDMA technology this paper discusses the advantages and necessity of this scheme, and gives the implementation scheme of dynamic slot allocation, equipment control, and long-range video transmission, including the proper algorithm example. This product has wide application prospect in railway, highway, and transportation business.
