摘要

深圳市无线传输系统是基于数字微波传输和NI复用多业务传输设备等传输系统。基于同一体系的无线传输,同一基础平台,汇聚多种业务应用,可在任何拓扑形式结构上运行。实现多种业务灵活传输应用,深圳市国标地面数字电视单频网所有信号的传输与交换,正向下发的节目源信号及回传的监控信号,实现了HD-SDI,SDI,ASI,AES/EBU,IP等信号在星型网络拓扑结构里灵活稳定传输,结合数字微波车实时新闻采集音视频传输,实现现有主流业务的无线传输。
        Shenzhen wireless transmission system is based on digital microwave transmission and NI multiplexed multi-service transmission equipment and other transmission systems. Based on the same system of wireless transmission, the same basic platform can aggregate multiple service applications and can run on any topology structure. Achieve a variety of business flexible transmission applications. Shenzhen City GB terrestrial digital TV single frequency network transmission and exchange of all signals, the forward of the program source signal and the return of the monitoring signal, to achieve HD-SDI, SDI, ASI, AES/EBU, IP and other signals are transmitted flexibly and stably in the star network topology, combined with digital microwave car real-time news collection audio and video transmission to achieve wireless transmission of existing mainstream services.
