移动互联网时代的电竞体育赛事转播传输低延迟传输技术探究

Research on Low Latency Transmission Technology of E-Sports Event Broadcast Transmission in The Era of Mobile Internet

文章主要讨论了移动互联网时代背景下,赛事直播在电竞和体育领域中采用的不同传输协议及其适用性。具体比较了网页实时通信(Web Real-Time Communications,WebRTC)、超文本直播流(Hyper Text Transfer Protocol Live Streaming,HLS)、低延迟超文本直播流(Low Latency Hyper Text Transfer Protocol Live Streaming,LL-HLS)、基于超文本传输协议的Flash视频协议(HyperText Transfer Protocol Flash Video,HTTP-FLV)、基于HTTP的动态自适应流媒体传输协议(Dynamic Adaptive Streaming over HTTP,DASH)和低延迟基于超文本传输协议的动态自适应流媒体传输协议(Low Latency Dynamic Adaptive Streaming over HyperText Transfer Protocol,LL-DASH)传输协议,分析了这些协议在电竞体育赛事场景下的延迟和终端支持情况,并结合实际例子探讨传输架构及其影响。研究结果表明,不同的传输协议有各自的优缺点,可在不同场景下应用。而对于常规赛转播,传输架构也是决定延迟的重要因素,分布式传输架构能够更好地实现低延迟和稳定性。因此,文章对于选择合适的传输协议和传输架构具有一定的借鉴意义。

The article discusses different transmission protocols and their applicability for live event streaming in the context of the mobile Internet era in the e-sports and sports domains.Specifically,it compares Web Real-Time Communications(WebRTC),Hyper Text Transfer Protocol Live Streaming(HLS),Low Latency Hyper Text Transfer Protocol Live Streaming(LL-HLS),HyperText Transfer Protocol Flash Video(HTTP-FLV),Dynamic Adaptive Streaming over HTTP(HTTP-FLV),and HTTP Live Streaming(HLS).Dynamic Adaptive Streaming over HTTP(DASH)and Low Latency Dynamic Adaptive Streaming over HyperText Transfer Protocol(LL-DASH)transport protocols.(LL-DASH)transport protocols,analyze the latency and endpoint support of these protocols in e-sports event scenarios,and discuss the transport architectures and their impacts with practical examples.The results show that different transmission protocols have their own advantages and disadvantages and can be applied in different scenarios.For regular season broadcast,the transmission architecture is also an important factor in determining the latency,and the distributed transmission architecture can better achieve low latency and stability.Therefore,the article has some implications for choosing the appropriate transmission protocol and transmission architecture.
