Industry analysis | the future of real-time audio and video

Full English name of real-time audio and video Real-TimeCommunication, abbreviation RTC, Is a terminal service , Provide high concurrency for the industry 、 Low delay 、 HD fluency 、 Safe and reliable whole scene 、 Full interactive audio and video services .

With the popularization of mobile Internet and the wide application of intelligent terminal equipment , Real time audio and video is gradually becoming the mainstream interactive way . Online education 、 Social entertainment 、 Interactive e-commerce and other popular fields have been widely used , It also enables more innovative scenarios , Such as finance 、 Government and enterprise services 、loT、 Medical treatment, etc. , Help people enjoy more convenient and humanized life services .

In the past decade , Not only Tencent cloud 、 Alibaba cloud 、 Netease, Yunxin and other giant manufacturers also have voice network agora、 Baijiayun 、 Micro roar and other start-ups “ up-and-coming star ” They are also based on real-time audio and video .

Based on the present , Is real-time audio and video track a good business ？ Is real-time audio and video a rough road ahead or a bright road ？

Basic function , It is destined to be a good business

2020 The epidemic appeared in , Offline economy is temporarily paralyzed , Online education 、 Videoconferencing 、 Online medicine 、 E-commerce live broadcast and other application scenarios become life “ new normal ”, After the scene of real-time interaction is enriched , Let real-time audio and video become the just needed function .

IResearch is in 《2021 Global Internet communication cloud Industry Research Report 》 In the said ,2020 In, the global market reached 40 Billion dollars , Affected by the epidemic , Retail customer service 、 E-commerce live broadcast 、 Games, short videos and other scenarios have increased the demand for communication cloud .2020 In, the growth rate of global Internet communication cloud continued to increase to 62.6%. With the improvement of infrastructure , superposition 5G、 The development of Internet of things and other technologies , Expect to 2024 In, the global market will reach 182 Billion dollars , And the market remains 40% High growth of the above .

IDC China also said , It is expected that the video cloud market in China will remain 50% The compound annual growth rate above , To 2024 The annual scale will exceed 1500 The scale of billion yuan . And artificial intelligence 、5G、 New technologies such as edge computing have also brought long-term technological dividends to the audio and video industry .

The future is by no means smooth , The road ahead must be full of thorns

In terms of market environment ,“ Education double minus ”, Online education has been hit positively . General Office of the CPC Central Committee 、 The general office of the State Council printed and distributed 《 Opinions on further reducing students' homework burden and off campus training burden in the stage of compulsory education 》, Discipline training institutions shall not be listed for financing . So that real-time audio and video has lost a promising way .

Some time ago “ Game approved ”, Issued by relevant departments 《 Notice on preventing minors from addicting to online games 》 Relevant provisions , Strictly limit the playing time of minor users , Increase the intervention for minors' game consumption , Suppressed the barbaric development of some pan entertainment fields . Pan entertainment as a key area of real-time audio and video services , Withstand this pressure , It will also affect the real-time audio and video market in the short term .

Current communication technology realizes low delay 、 Low carton 、 High quality real-time communication is not difficult , The delay of audio and video data transmission shall not exceed 400ms, But in ultra clear picture quality 、 Super sound quality 、 Global connectivity 、 Super high concurrency 、 Equipment adaptation and other aspects still need to be improved . Real time audio and video across platforms and terminals should be supported iOS、Android、Windows、macOS、Web、 Small programs and other multi platform interoperability .

At present, real-time audio and video technology tends to be mature , There is not much room for real growth . Real time audio and video can be basically separated from the R & D period , Into the harvest . Secondly, the further maturity of network communication technology , Satellite Internet and 5G, Will be the signal transmission range 、 Signal stability is guaranteed .

For example, sound network Agora, Developed the original SD-RTN Global transmission network , Combine intelligent dynamic routing and Last mile Algorithm , A technological breakthrough has been achieved in the interactive ultra-low delay .

anyRTC, Use the unique GT-RTN（Global Teamwork Real-time Network） Global cooperative real-time transmission network , Designed for two-way real-time audio and video interaction . In the context of real-time communication , Ultra high definition audio and video transmission , Detect the network state at high speed and formulate appropriate resistance and transmission strategies according to the network state , To this end, it provides a solution with high quality and high reliability that can adapt to various complex scenarios , Meet the integrated communication needs of offshore enterprises .

future 5G Extensive promotion of Commercial Technology , It is expected to continue to promote the industrial Internet 、 Scenes such as the Internet of things have become new growth points of real-time audio and video .anyRTC As one of the earliest cloud communication manufacturers to provide audio and video services in China, it will help enterprises meet 5G, Own independent intellectual property rights , After years of algorithm optimization 、 Technology upgrade 、 network optimization 、 Scheme structure adjustment, etc , Improve the effect of the scheme , Quickly solve technical difficulties .
