摘要
介绍济南广播电视台隧道调频广播覆盖系统部署情况,在不改变现有隧道调频广播覆盖监控系统及传输链路前提下,为了提升隧道调频广播的安全级别,提出一种基于云平台部署音频分时比对系统的设计方案。通过引入音频分时比对技术,能够对隧道调频覆盖系统播出过程中的信号进行监测、比对和预警,及时发现异常信号,可以有效地提高隧道调频广播的播出质量和安全性。
This paper introduces the deployment of tunnel FM broadcasting coverage system at Jinan radio and television station.Without changing the existing tunnel FM broadcasting coverage monitoring system and transmission link,in order to improve the security level of tunnel FM broadcasting,a design scheme for deploying audio time-sharing comparison system based on cloud platform is proposed.By introducing the audio time-sharing comparison technology,it can monitor,compare and warn the signals in the broadcast process of the tunnel FM coverage system,find abnormal signals in time,and effectively improve the broadcast quality and safety of the tunnel FM broadcasting.
