摘　　要：探索电视转型升级的路上,通过IP流的传输进行远程制作是一个比较积极的应对方案。如何在公网环境下进行信号的实时传输和切换,如何保证信号的低时延和高质量,是需要不断实验和改进的。因此,研究5G环境下影响图像质量和传输时延的具体相关参数,不但实现了多迅道实时传输的REMI远程制作模式,也摸索了一套适合广电制作域的编解码参数配比方案。To explore the way of TV transformation and upgrading,remote production through IP stream transmission is a more active solution.How to transmit and switch signals in real time in the public network environment,and how to ensure the low delay and high quality of signals need continuous experiments and improvements.This paper studies the specific parameters affecting the image quality and transmission delay under 5G environment.This paper presents the REMI remote production mode of multi-channel real-time transmission,and explores a set of coding and decoding parameters matching scheme suitable for radio and television production field.
