摘　　要：SRT协议是一种新兴的视音频传输协议,本文结合安徽省首次5G直播的案例,从SRT协议的链路分析入手,提出了一个衡量SRT链路可靠性的指标:安全冗余量(Secure-Margin),并介绍如何参照该指标来部署一个可靠的SRT传输链路,最后分析在不同直播场景下的参数调整策略。SRT protocol is an emerging video and audio transmission protocol. Starting with link analysis of SRT protocol, this paper combines the first 5 G live broadcasting in Anhui puts forward an index to measure SRT link reliability, which is Secure Margin, introduces how to deploy a reliable SRT transmission link according to the index, and finally analyzes parameter adjustment strategy in different live broadcasting scenarios.

关 键 词：5G SRT 安全冗余量 延时量 带宽开销
