In July, the 3rd World Internet Communication Cloud Conference (WICC 2021) hosted by Rongyun, a leading global Internet communication cloud manufacturer, also entered the countdown. WICC has always taken it as its mission to foresee the cutting-edge technology in the field of communication cloud and lead the development of the industry. With the theme of “New Vision · Connecting Future”, Sun Lifeng, a professor from Tsinghua University, was invited to the summit forum in the morning for the first time. Center on the research hotspot of “AI+ Network Audio and Video Service”, he introduced the technology development trend of the combination of AI and audio and video.
This is also the new highlight that WICC 2021 will bring to developers from the academic research direction in response to the guidance of national policies and promote the deep integration of industry, education and research. Those who want to know new audio-video technologies and applications can pay attention to it.
Promote in-depth exchanges and cooperation between industries, universities and research institutes
As the academic representative of the conference, Sun Lifeng is a professor of computer science and technology at Tsinghua University. He has published more than 120 papers in international journals and conferences, and granted 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 characteristics of the research are as follows: at the same time of basic research, it pays attention to the combination with the industry to solve the practical problems faced by the 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 a deep reinforcement learning based video bit rate adaptive algorithm, which was integrated into Huawei’s continuous audio and video calling products, and has been successfully deployed in Huawei Mate30, P40 and other mobile phone platforms, effectively improving the picture quality and fluency of real-time video communication in mobile terminals under complex network environment.
Therefore, Professor Sun Lifeng believes, “Communication cloud and network audio and video services are rapidly developing fields, which especially require in-depth exchanges and cooperation between academia and industry to solve bottlenecks in industry development and practical problems faced by the industry at the front line. The WICC held by Rongyun can provide a platform for the industry to communicate, strengthen the cooperation between industry, university and research, and clarify the trend of industrial development through joint discussion. This is the reason why I am very willing to participate in it.”
From AI to endogenous intelligence, it is the development trend of Internet audio and video services
Audio and video services have become the infrastructure of Internet information services. Especially in the post-epidemic era, online education, video conferencing, telemedicine, live shopping and other application scenarios have become the “new normal” and “new business mode” for people’s life, work and entertainment. The challenges faced by the user experience of high quality and low latency Internet audio and video services include the complexity of large-scale systems on the cloud side, the dynamics of network state and user behavior, etc.
Therefore, Professor Sun Lifeng will deliver the keynote speech of “Internet Audio and Video Service: From AI Enabling to Wisdom Ending” for developers at the morning summit forum. AI, especially machine learning represented by deep learning, has made great strides in recent years and has begun to empower various fields, he said. Network audio and video services and cloud computing are faced with the challenges of the complexity and uncertainty of the super-scale system. 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 the self-evolution of the system and achieve the endogenous intelligence through the new machine learning framework.
From the perspective of academic frontier and industrial practice, Professor Sun Lifeng’s speech will elaborate on the characteristics and challenges of Internet audio and video services and the technical development roadmap of AI+ Internet audio and video services, so as to help developers understand the application scenarios and technical challenges of current Internet audio and video services. Learn about the technical framework of AI+ Internet audio and video services, the cutting-edge exploration and practice in 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 changes that 5G will bring to the communication cloud industry along with the further landing of 5G and the integration of 5G with AI, AR/VR and other technologies, as well as the characteristics of new scenarios generated under the new technologies, 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 edge end/cloud network end is worth studying. From the perspective of transmission, the traditional user-oriented (human-oriented) service quality and user experience will be expanded to consider the demand for data transmission between machines and devices.
In the future, Professor Sun Lifeng will continue to focus on AI field, cloud side/cloud network side application scenarios, new decentralized machine learning and its application in communication cloud, and study how to achieve endogenous intelligence and system self-evolution. These new studies, on the one hand, can bring new visual experience in the future Internet application of 3D video. On the other hand, they will promote the further integration of virtual environment and the real world, and give birth to new economic models. For example, the concept of meta-universe, which emerged recently, has already attracted the attention of the industry. Professor Sun Lifeng hopes that the research results of the academic circle can be implemented in the industry through a variety of ways of cooperation, and truly serve the practical application of the industry.
conclusion
WICC 2021 is still in full preparation. It can be seen from the existing revealed plots that the integration of academic elements and the promotion of the in-depth combination of industry, education and research will be the new content and new highlights that this conference is worth looking forward to. Enable the research results of cutting-edge science and technology to be applied in more communication cloud scenarios, which will add infinite possibilities to the development and application of communication cloud technology in the future.
