摘要
网际互连协议(Internet Protocol,IP)化网络作为一种新兴的传输技术,正在改变传统的电视制作和播出模式。基于此,概述了IP化技术的相关概念,分析了IP化技术的数字编码和分组传输机制,阐述了IP化技术在推动电视制播融合方面的作用,提出了电视制播IP化网络的分层架构,解析了IP化核心网和接入网的组成,以及软件定义网络(Software Defined Network,SDN)在IP化网络中的控制作用。
The Internet Protocol(IP)network,as an emerging transmission technology,is changing the traditional mode of television production and broadcasting.Based on this,the relevant concepts of IP technology are summarized,the digital encoding and packet transmission mechanisms of IP technology are analyzed,the role of IP technology in promoting the integration of television production and broadcasting is explained,the hierarchical architecture of television production and broadcasting IP network is proposed,the composition of IP core network and access network is analyzed,and the control role of Software Defined Network(SDN)in IP network is discussed.
