Alibaba cloud released the industry's first "best practice map of live video technology"!

 2022 Alibaba cloud live broadcast Summit on 7 month 8 Sunset curtain , Many technical experts and industry pioneers in the live broadcast industry , Discuss the evolution trend and future development of live broadcast technology in the super video era .

This conference , Heavyweight released the industry's first 「 Best practice diagram of live video technology 」, Summarize the live broadcast technology as 7 spot ： Cloud native 、 Highly reliable 、 Low delay 、 Ultra-high resolution 、 Intelligent 、 Professional and multi scene , And around “ cloud 、 End 、 network ” Trinity technology architecture 、 Multi scenario product solutions 、 Discuss ecological development and other aspects .

The trend of live video broadcasting is to reduce the delay of video , Including transmission delay and calculation delay .

In the past , The public's understanding of delay mainly focuses on transmission delay , When the transmission delay is 3-10 Seconds , Such video has the property of broadcasting , Such as ： Live sports events . And live broadcast scenes with strong interactive needs, such as interactive classes , The requirement for delay is 250 millisecond -800 Within milliseconds . When the delay keeps decreasing , from 80 Milliseconds to 50 millisecond , Such video delay has controllability and immersion .

Except for transmission delay , Video codec 、 High definition computing and other technologies will also bring computing power delay . Alibaba cloud's live broadcast technology is based on the cloud's native base and distributed edge nodes , Through the transformation of the transmission protocol , Integrate real-time media processing power and edge computing power , It can greatly and effectively reduce the transmission delay and calculation delay , And pass GRTN、RTS、 Real time media processing capability 、 video +AI And so on , Complete the best practice of low latency , Achieve the best balance between cost and experience .

There are three main aspects of cloud Nativity advocated by Alibaba cloud ：“ Service oriented products ”,“ Random elasticity ”,“ Soft and hard integration 、 Cloud and edge 、 Cloud in one ”, And video technology is exactly the best practice of cloud Nativity .

Cloud infrastructure , Including the central node 、 Edge node 、CDN The network is the foundation to ensure large-scale distribution and transmission ; Cloud primordial in time 、 Space 、 Multidimensional elasticity on heterogeneity , It can realize the quantitative and flexible adjustment of data cloud edge computing 、 Dozens of businesses are mixed 、100+ Real time transmission and AI Tasks, multi models, multi systems, heterogeneous mixed running, etc , Bring unlimited computing power to the video business while effectively controlling costs , Generate more new scenes .

in addition , Today, with more and more audio and video end-to-side devices ,“ cloud ” And “ End ” The coordination of is becoming more and more important , Relying on Alibaba cloud's powerful cloud computing power , It can make the end more intelligent 、 Lighter 、 More flexible 、 Let developers create thousands of innovative applications , Its development efficiency 、 O & M costs 、 Ductility has been greatly optimized .

With the broadcast economy 、 Internet innovation and traditional industrial upgrading are further integrated , The innovation of technology and application has become an important driving force for the development of the live video industry .5G、AR、VR The development of technology and the improvement of infrastructure , Lower latency 、 Higher definition 、 More immersive interaction , It will change the way many industries interact with humans . It has precipitated Alibaba cloud's video technology for many years 「 Best practice diagram of live video technology 」 It will boost the development of many industries , Explore the innovative application future of live broadcasting technology .

About 「 Best practice diagram of live video technology 」 In-depth analysis and sharing , It will be launched in the near future , Stay tuned .
