利用SDH网传输 AoIP信号的测试研究

Testing and Research of AoIP Signal Transmission by SDH Network

应用AoIP技术可以把广播播控系统中的数字音频信号通过网线形成一个IP音频网,这对汇集音频信号源、加强系统调度管理都具有非常重大的意义。目前在广电行业的应用更多局限于广播主控和监测,没有充分发挥AoIP技术作为高品质传输协议的作用,通过描述在广电SDH网中传输AoIP协议音频信号的研究思路和一些实际测试结果,对深化AoIP技术在广播中心的应用、挖掘AoIP技术潜力具有一定的参考意义。

The application of AoIP technology can form an IP audio network through the network cable of the digital audio signal in the broadcasting control system,which is of great significance for the collection of audio signal sources and the strengthening of system scheduling management.At present,the application in the radio and television industry is more limited to broadcast master control and monitoring,which cannot fully play the role of AoIP technology as a high-quality transmission protocol.This paper describes the research idea and some actual test results of AoIP protocol audio signal transmission in SDH network,which is of certain reference significance for deepening the application of AoIP technology in broadcasting center and tapping the potential of AoIP technology.
