摘要
在数字化媒体环境下,传统广播电视行业的竞争日益激烈,同时面临着技术变革带来的挑战,因此有必要建立一个全面的直播传输试验平台,以适应新时代的需求。首先介绍了设计目标,其次分析了全媒体网关技术的原理、多协议互转和安全可靠传输协议(Secure Reliable Transport,SRT)远程传输信号等内容,最后深入研究了4G/5G超低延迟编码传输背包系统技术,包括超低延时编码传输技术原理和编码原理等内容。分析这些技术旨在为河南广播电视台直播传输试验平台的设计提供理论和技术支持,促进广播电视行业的创新发展。
In the digital media environment,the traditional radio and television industry is increasingly competitive,while facing the challenges brought by technological change,so it is necessary to establish a comprehensive live transmission test platform to meet the needs of the new era.This paper first introduces the design objectives,then analyzes the principle of all-media gateway technology,multi-protocol intertransfer and Secure Reliable Transport(SRT)remote transmission signals,etc.Finally,it deeply studies the 4G/5G ultra-low delay coded transmission backpack system technology.It includes the principle of ultra-low delay coding transmission technology and coding principle.The analysis of these technologies aims to provide theoretical and technical support for the design of the live transmission test platform of Henan Radio and Television Station,so as to promote the innovative development of the radio and television industry.
