IP时代下的电视播出系统架构思考

Reflection on the Architecture of TV Broadcasting System in the IP Era

随着4K、8K超高清技术的出现、信息技术(Information Technology,IT)的迅猛发展、虚拟化技术及基于网际互连协议(Internet Protocol,IP)网络的传输标准日益完善,电视系统传统的串行数字接口(Serial Digital Interface,SDI)技术架构在带宽、互联网应用、灵活配置等方面显得越来越力不从心。虚拟化技术、云技术以海量的带宽、灵活的资源配置方式、多样的兼容性为电视播出系统的架构提供了新的思路。基于此,阐述电视播出系统架构的过去、现在、未来,对今后电视播出系统架构的选择进行深层次的思考。

With the emergence of 4K,8K ultra-high definition technology,the rapid development of Information Technology(IT),virtualization technology and the transmission standards based on the Internet Protocol(IP)network are increasingly perfect,the traditional Serial Digital Interface(SDI)technical architecture of television system is becoming more and more inadequate in terms of bandwidth,internet application and flexible configuration.Virtualization technology and cloud technology provide new ideas for the architecture of television broadcasting system with massive bandwidth,flexible resource allocation and various compatibility.Based on this,this paper expounds the past,present and future of the television broadcasting system architecture,and deeply thinks about the choice of the future television broadcasting system architecture.
