WICC 2021 will be held soon, Tsinghua University professors will share research on AI+ network audio and video services

In July, the 3rd Global Internet Communication Cloud Conference (WICC 2021) hosted by Rongyun, a leading global Internet communication cloud manufacturer, also entered the countdown. WICC has always been committed to foreseeing 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, Professor Sun Lifeng of Tsinghua University was invited to sit down for the first time. Focusing on the research hotspot of "AI + network audio and video services", the technology of combining AI with audio and video was introduced. development trend.

This is also a new bright spot for developers from the academic research direction of WICC 2021 in response to national policy guidance to promote the in-depth integration of industry, university and research. We hope that friends who understand new audio and video technologies and applications can focus on it.

Promote in-depth exchanges and cooperation between industry, university and research

As a representative of the academic community at the level of the conference to promote industry-university-research exchanges, Sun Lifeng is a long-term 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 authorized 20 national invention patents. 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: in addition to basic research, it focuses on integrating with industry to solve practical problems faced by industrial applications.

Previously, the research group led by Professor Sun Lifeng developed the "3D Video Coding and Webcast System", which was applied to CCTV’s 2012 CCTV Network Spring Festival Gala and the 3D Webcast of the European Football Championship. This is the first large-scale Internet broadcast in China. The large-scale 3D video live broadcast service provides a new viewing experience for the broad audience and has attracted great attention from the industry.

The research team also cooperated with Huawei to develop a deep reinforcement learning-based video bit rate adaptive algorithm, which is integrated into Huawei's Changlian audio and video call products. It has been successfully deployed on Huawei Mate30, P40 and other mobile phone platforms, effectively improving The picture quality and fluency of mobile terminal video real-time communication in a complex network environment.

Therefore, Professor Sun Lifeng believes: “Communication cloud and network audio and video services are fast-developing fields, and in-depth exchanges and cooperation between academia and industry are particularly needed to solve bottlenecks in industry development and solve practical problems facing the industry. The WICC conference can provide the industry with a platform for exchanges, strengthen cooperation between industry, university and research, and clarify the trend of industry development through joint discussions. This is the reason why I am very willing to participate."

From AI empowerment to endogenous wisdom, it is the development trend of Internet audio and video services

Audio and video services have become the Internet information service infrastructure, especially in the post-epidemic era. Application scenarios such as online education, video conferencing, telemedicine, and live shopping have become the "new normal" and "new business format" for people's lives, work, and entertainment. . The challenges facing the user experience of high-quality, low-latency Internet audio and video services include the complexity of large-scale systems on the cloud side, the network status and the dynamics of user behavior.

Therefore, Professor Sun Lifeng will give developers a keynote speech on "Internet Audio and Video Services: From AI Empowerment to Wisdom Endogenous" in the morning summit forum. He believes that AI, especially machine learning represented by deep learning, has made great progress in recent years and has begun to empower various fields. Network audio and video services and cloud computing are facing the challenges of super-large-scale system complexity and uncertainty. Machine learning will provide new ideas and technical ways to solve these challenges, and realize the self-evolution of the system through the new machine learning framework to reach the endogenous wisdom. It is the development trend of Internet audio and video services.

From the perspective of academic frontiers and industrial practice, Professor Sun Lifeng’s speech will explain the characteristics and challenges of Internet audio and video services, and the technical development roadmap of AI+ Internet audio and video services to help developers understand the current application scenarios and technologies of Internet audio and video services. Challenge, 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 cutting-edge technologies such as 5G and AI will bring new changes to the communications industry

When talking about the changes that will be brought to the communication cloud industry with the further implementation of 5G and the integration of 5G with AI, AR/VR and other technologies, as well as the characteristics of new scenarios generated by new technologies, Professor Sun Lifeng believes: The further implementation of 5G will drive the development of the industrial Internet. Communication cloud will pay more attention to edge computing from the perspective of computing. The new computing model of cloud edge/cloud network terminal is worth studying; from the perspective of transmission, it will be traditional user (human)-oriented services Quality and user experience are extended to consider the data transmission needs of machines and machines, and between equipment and equipment.

In the future, Professor Sun Lifeng will still focus on the AI field, facing the application scenarios of the cloud end/cloud network end, new decentralized machine learning and its application in the communication cloud, and research how to realize the endogenous intelligence and self-evolution of the system. These new researches, in the future Internet applications of 3D video, on the one hand, can bring new visual experiences, on the other hand, they will promote the further integration of the virtual environment and the real world, and give birth to new economic models, such as the recent rise of meta-universe The concept has attracted the attention of the industry. Professor Sun Lifeng hopes that the research results of academia can be implemented in the industry through a variety of cooperation methods and truly serve the practical application of the industry.

Concluding remarks

WICC 2021 is still under intensive preparations. From the existing spoilers, it can be seen that integrating the elements of academia and promoting the in-depth integration of industry, university and research are the new content and new highlights of this conference that are very worth looking forward to. Enabling the research results of cutting-edge technology in more communication cloud scenarios will add infinite possibilities for the development and application of communication cloud technology in the future.
