Alibaba Cloud released the industry's first "Best Practice Map of Live Video Technology"!

The 2022 Alibaba Cloud Live Streaming Summit came to an end on July 8. A number of technical experts and industry pioneers in the live broadcast industry jointly discussed the evolution trend and future development of live broadcast technology in the hyper-video era.

At this conference, the industry's first "best practice map of live video technology" was released, and the live broadcast technology was summarized into 7 points: cloud native, high reliability, low latency, ultra-high definition, intelligent, professional and many more. Scenarios, and discuss on the technical architecture of "cloud, terminal, network" three-in-one, multi-scenario product solutions, ecological development and other aspects.

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

In the past, the public's understanding of delay mainly focused on transmission delay. When the transmission delay is within 3-10 seconds, such a video has the property of being broadcast, such as live sports events. For live broadcast scenarios with strong interactive needs, such as interactive classrooms, the delay requirements are in the range of 250 milliseconds to 800 milliseconds. When the delay is continuously reduced, from 80ms to 50ms, such video delays are controllable and immersive.

In addition to the transmission delay, the calculation of video encoding and decoding, high-definition and other technologies will also bring about a delay in computing power. Alibaba Cloud's live broadcast technology is based on cloud-native bases and distributed edge nodes. Through the transformation of transmission protocols, the integration of real-time media processing capabilities and edge computing power can significantly reduce transmission and computing delays. RTS, real-time media processing capabilities, video + AI and other technical applications, complete the best practice of low latency, and achieve the best balance between cost and experience.

There are three main points of cloud native advocated by Alibaba Cloud: "service-oriented products", "flexibility at will", "integration of software and hardware, integration of cloud and edge, and integration of cloud", and video technology is precisely the best practice of cloud native.

Cloud infrastructure, including central nodes, edge nodes, and CDN networks, is the basis for ensuring large-scale distribution and transmission; cloud-native multi-dimensional elastic capabilities in time, space, and heterogeneity can realize flexible adjustment of digital cloud edge computing, Mixed running of dozens of services, 100+ real-time transmission and AI tasks, multi-model, multi-system, heterogeneous running, etc., bring unlimited computing power to the video business, while effectively controlling costs, and generating more new scenarios.

In addition, in today's increasingly abundant audio and video end-side devices, the collaboration between "cloud" and "end" is becoming more and more important. Relying on Alibaba Cloud's powerful cloud computing power, the end can be made smarter, lighter, and more convenient. It is more flexible, allowing developers to create innovative applications with thousands of people and thousands of faces, and its development efficiency, operation and maintenance costs, and scalability have been greatly optimized.

With the further integration of the live broadcast economy, Internet innovation and the upgrading of traditional industries, technology and application innovation has become an important driving force for the development of the live video industry. The development of 5G, AR, and VR technologies and the improvement of infrastructure, lower latency, higher-definition, and more immersive interaction methods will change the interaction methods of many industries and humans. The "Best Practice Map of Video Live Technology", which has accumulated Alibaba Cloud's video technology for many years, will boost the development of many industries and explore the future of innovative applications of live broadcast technology.

The in-depth analysis and sharing of the "Best Practice Diagram of Video Live Technology" will be launched in the near future, so stay tuned.
