Design and Implementation of Radio Central Broadcasting and Control System for Radio and Television Station

本文介绍一套以主、备、交换三套矩阵为核心,双数字音频矩阵光纤与直通微波传输相结合的广播核心播控系统。该系统使用了“核心矩阵+远端子矩阵”的播控传输一体化架构,基于AES3、AES10和AoIP等技术,创新性地采用多层智能切换器联动的自动应急模式,有利于提高节目技术质量、生产效能和安全播出保障能力。

This paper introduces a set of radio central broadcasting and control system,which is centrally based on three matrix systems including the main,backup and exchanging matrixes,with the combination of dual digital audio matrix optical fiber and one direct microwave transmission route.Based on AES3,AES10 and AoIP audio technologies,the system applies the broadcasting control and transmission integrated architecture of“core matrixes+remote terminal matrix”,and innovatively adopts the automatic emergency mode owing to the linkage mechanism of the multilayer intelligent audio switchers,which is conducive to improving the program technical quality,production efficiency and the ability of safe broadcasting.
