摘　　要：在SMPTE-2110无压缩标准建议下,总台新搭建的4K超高清EFP制作系统已经全面实现网络化和IP数据流化。在这种广电三层结构的IP制作网内由于通用COTS交换机占据了系统核心位置,视、音、辅助数据流的转发成为常态。为了实现对IP业务数据流信号的互通、管理、监控以确保节目生产正常化,网络控制器和广电终端控制器就成为了系统的重要控制核心。本文将主要阐述分析以Cisco通用交换机为系统核心的超高清4K-EFP制作系统中DCNM网络控制器的概念、任务角色和需要部署的安全策略问题,也对未来超高清IP系统中网络控制器的发展做出展望。Under the guidance of the SMPTE-2110 uncompressed standart,the newly 4K-EFP UHD production system of CCTV has fully realized the networking and IP data streaming.In the IP-based production system with three layers of broadcasting structure,the COTS switch occupies the core position of the 4K-EFP system,the forwarding of video,audio and auxiliary data streams become the norm.In order to realize the communication,management and monitoring of IP service data stream signal to ensure the normalization of program production,network controller and broadcast terminal controller have become the important control core in the 4K system.This paper will mainly analyze the DCNM network controller in 4K-EFP UHD production system with cisco COTS switch as the core of the system,including the concept,task role and security policy to be deployed,and also make a prospect for the future development of network controller in UHD IP system.
