In July, the third Global Internet Communication Cloud Conference (WICC 2021) hosted by Rongyun, a leading global Internet communication cloud manufacturer, has also entered the countdown. WICC has always been committed to anticipating the cutting edge technologies in the communications cloud field and leading the development of the industry. The theme of this conference is “New Vision · Connecting the Future”. In the morning summit forum, Sun Lifeng, a professor from Tsinghua University, was invited to talk for the first time. Centering on the research hot spots of “AI+ Network audio and video services”, he introduced the technical development trend of the combination of AI and audio and video.
This is also a new highlight that WICC 2021, in response to the guidance of national policy, promotes the deep integration of industry, university and research and brings to developers from the direction of academic research. Those who want to know about new audio and video technologies and applications can focus on it.
To promote in-depth exchanges and cooperation among enterprises, universities and research institutes
As the academic representative of the conference to promote industry-university-research exchanges, Sun Lifeng is a professor from the Department of Computer Science and Technology of Tsinghua University. He has published more than 120 papers in international journals and conferences, and has authorized 20 national invention patents. His research interests focus on streaming media technology, multimedia edge computing, video intelligent analysis and processing, media big data and social media computing. The research features are as follows: while doing basic research, it pays attention to the combination with industry to solve the practical problems faced by industrial application.
Previously, led by professor li-feng sun group, has developed “3 d live video coding and network system”, applied to the CCTV 2012 CCTV Spring Festival gala and 3 d live webcast European football championships, this is the first time domestic large-scale 3 d video broadcast services via the Internet, for the general audience provides a brand-new viewing experience, The industry has been highly concerned.
The research group also cooperated with Huawei to develop the video bitrate adaptive algorithm based on deep reinforcement learning, which was integrated into Huawei Changlian audio and video call products and successfully deployed in huawei Mate30, P40 and other mobile phone platforms, effectively improving the picture quality and smoothness of real-time video communication of mobile terminals in complex network environment.
Therefore, Professor Sun Lifeng believes: “Communication cloud and network audio and video services are rapidly developing fields, especially in need of in-depth exchanges and cooperation between academia and industry, to solve the bottleneck problems of industry development and solve the practical problems faced by the industry. The WICC conference held by Rongyun can provide an exchange platform for the industry, strengthen the cooperation between industry, university and research institute, and clarify the development trend of the industry through joint discussion. This is the reason why I am very willing to participate in it.”
The development trend of Internet audio and video services is from AI empowerment to endogenous wisdom
Audio and video services have become the Internet information service infrastructure, especially in the post-EPIDEMIC era, where online education, video conferencing, telemedicine, live shopping and other application scenarios have become the “new normal” and “new business model” for people’s life, work and entertainment. The challenges to user experience of high-quality, low-latency Internet audio and video services include the complexity of large-scale systems on the cloud side, network state and dynamic user behavior.
Therefore, Professor Sun Lifeng will bring the keynote speech “Internet Audio and Video Services: From AI Empowerment to Intelligence endogenous” to developers in the morning summit forum. AI, particularly machine learning represented by deep learning, has made great strides in recent years and is starting to empower all sorts of fields, he said. Network audio and video services and cloud computing are faced with challenges of complexity and uncertainty of super-large scale systems. Machine learning will provide new ideas and technical approaches to solve these challenges. It is the development trend of Internet audio and video services to realize system self-evolution and endogenous wisdom through new machine learning frameworks.
From the perspective of academic frontier and industrial practice, Professor Sun Lifeng’s speech will elaborate the characteristics and challenges of Internet audio and video services, the technical development roadmap of AI+ Internet audio and video services, and help developers understand the application scenarios and technical challenges of current Internet audio and video services. Understand the technical framework of AI+ Internet audio and video services, the cutting-edge exploration and practice of academia/industry, and the development trend of Internet audio and video intelligent services.
The integration of 5G with cutting-edge technologies such as AI will bring new changes to the communications industry
When talking about the further landing of 5G, the integration of 5G with AI, AR/VR and other technologies, the changes it will bring to the communication cloud industry, and the characteristics of the new scenes generated under the new technology, Professor Sun Lifeng believes that: The further landing of 5G will drive the development of industrial Internet. Communication cloud will pay more attention to edge computing from the perspective of computing. The new computing mode of cloud side/cloud network is worth studying. From the perspective of transmission, it will expand from the traditional user-oriented quality of service and user experience to consider the data transmission requirements between machines and devices.
In the future, Professor Sun will continue to focus on AI, cloud side/cloud network side application scenarios, new decentralized machine learning and its application in communication cloud, and how to realize endogenous intelligence and system self-evolution. These new researches, in the future, in the field of 3D video Internet application, on the one hand, can bring new visual experience, on the other hand, will promote the further integration of virtual environment and real world, and give birth to new economic models, such as the concept of meta-universe, which has aroused the attention of the industry. Professor Sun Lifeng hopes that the academic research results can be implemented in the industry through various ways of cooperation and truly serve the practical application of the industry.
conclusion
WICC 2021 is still in preparation, from the existing revealed plot can be seen, into the academic elements, promote the depth of the combination of production, learning and research, is the conference is very worth looking forward to the new content and new highlights. Enabling the research results of cutting-edge science and technology to be applied in more communication cloud scenarios will add infinite possibilities for the development and application of communication cloud technology in the future.
