当前,基于电影和电视工程师协会(The Society of Motion Picture and Television Engineers,SMPTE)2110标准的4K网际互连协议(Internet Protocol,IP)转播车和演播室节目制作技术系统应用已相对成熟.通过对近年来国内 4K IP转播车实例的学习考察,总结目前流行的 4K IP转播车核心网络架构特点,阐述以 14+2+2 讯道为设计目标的 4K IP转播车,依据SMPTE 2110和SMPTE 2022-7标准,介绍全IP化和双脊叶(Spine-Leaf)的网络架构设计思路.
Research on the Design of 4K IP Broadcast Vehicle Network Based on Double Ridge Architecture
Currently,The 4K Internet Protocol(IP)broadcast vehicle based on the Society of Motion Picture and Television Engineers(SMPTE)2110 standard and studio program production technology system application has been relatively mature.Based on the study and investigation of domestic 4K IP broadcast vehicle examples in recent years,this paper summarizes the core network architecture characteristics of the current popular 4K IP broadcast vehicle,and expounds the 4K IP broadcast vehicle designed with 14+2+2 channels.According to the SMPTE 2110 and SMPTE 2022-7 standards,this paper introduces the network architecture design of all IP and spine-leaf.
