摘　　要：当前,广播电视传输方式已从混合光纤同轴电缆(Hybrid Fiber Coax,HFC)网络向光纤到户(Fibre To The Home,FTTH)网络转变。与异步串行接口(Asynchronous Serial Interface,ASI)播出系统相比,IP信号传输方式更适应于全光网络及光传送网(Optical Transport Network,OTN)传输网络,在信源信号分配及监控手段、方式等方面也较为灵活、多变、全面。本文主要针对ASI播出系统与IP播出系统的组网配置进行介绍、分析,为相关单位进行播出系统选择提供参考。At present, the transmission mode of radio and television has changed from Hybrid Fiber Coax(HFC) network to Fiber To The Home(FTTH) network. Compared with the Asynchronous Serial Interface(ASI) broadcast system, IP signal transmission mode is more suitable for all-optical network and Optical Transport Network(OTN) transmission network, and it is also more flexible, changeable and comprehensive in source signal distribution and monitoring means and methods. This paper mainly introduces and analyzes the networking configuration of ASI broadcast system and IP broadcast system, so as to provide reference for relevant units to choose broadcast system.
