At the beginning of 2018, the audio and video technology ecology is not calm. Codec’s competition has entered an era of fierce competition. AV1 and domestic AVS2 have launched a challenge to HEVC. The final version 1.0 of WebRTC enables multimedia communication in browsers, mobile terminals and even IoT. The development of AI and blockchain technology is reacting with multimedia development and will become a new force to promote ecological development. At the same time, the exploration of new business scenarios, such as online answering, online catching dolls, O2O and new retail, has given the best practical environment for new technologies. In addition, new technology is affecting security, video conferencing, social networking, education, finance and other industries, and even reshuffling the industry ecosystem.

In 2018, LiveVideoStack will showcase the exploration and practice of new technologies in the field of audio and video, as well as the latest and best practices in emerging application scenarios and traditional industries through the “LiveVideoStack Meet: New Trends in Multimedia Development” series salon. On March 31, we will welcome the first stop of the series of salon — Beijing. At that time, five senior multimedia development gurus from Xiaomi, Toutiao, Ricoh Software Research Institute and Trisolar Cloud will look forward to the latest trend and technology practice of multimedia development together.


Lecturers and Topics

Huang Chuanzeng, head of multimedia audio technology in Toutiao Interactive Entertainment Department

Speaker: Graduated from The Institute of Acoustics, Chinese Academy of Sciences, worked in Dolby audio codec and sound processing research and development, and now Bytedance is the audio technology leader of multimedia development.

Topic: Technical evolution of audio Codec

In addition to h.264, which is widely used, and HEVC, which is copyrighted, AV1 and AVS2 are also emerging as the next generation of video codecs. The evolution of audio Codec has received relatively little attention, but it is also a critical part of multimedia development. This post will introduce the development of next-generation audio Codec and some direction of 3D spatial coding.


Bao Jinlong senior multimedia development engineer

I graduated from Beijing University in my early years. Master of Software Engineering. He has worked in several large software companies in the middle and senior technical positions, successfully organized the development of more than ten multimedia/streaming media software products, formulated EVD national specifications, etc. Over 20 years of C/C++ programming experience. Over 15 years of experience in multimedia codec, multimedia application software development. In video coding and decoding technology, network streaming media applications, live, on-demand, P2P, server cluster, multi-threaded development, parallel computing, distributed applications, machine learning and other underlying core technologies of the basic theory, framework standards and program implementation, as well as performance optimization and other fields.

Topic: Artificial intelligence enhanced real-time video super-resolution

Traditional video super-resolution technologies include sub-pixel extraction, edge enhancement, noise filtering and image sharpening, etc. These processes are very computation-intensive and generally require proprietary hardware to implement. The super-resolution technology shared this time combines the current advanced machine learning technology, and has the advantages of short training time and low hardware requirements. Through the efficient combination of multiple algorithms and HEVC decoder, the algorithm and code are highly optimized, which greatly improves the output quality and calculation speed of super-resolution image. It can achieve real-time output performance from 1080P to 4K on ordinary PC, and can reach 720P to 3K on mobile platform.


Cui Wenxiu director of Beijing Trimaran Technology Co., LTD

Speaker: More than 13 years of working experience in fortune 500 IT enterprises (Citrix, Symantec), with rich experience in r&d, after-sales, implementation, consulting, pre-sales and sales for enterprise customers. I once led the scheme design, project implementation, operation and maintenance support of information security projects and cloud computing projects of the world’s largest bank, insurance and telecom companies.

Topic: Real-time audio and video technology enables traditional industries

With the continuous development of science and technology, audio and video has gradually become an indispensable part of People’s Daily life because it carries more content and brings better experience. Meanwhile, traditional industries have begun to explore how to fit in with audio and video technology, and have derived explosive products such as online doll catching and live answering questions. This sharing will introduce the development status of real-time audio and video technology, analyze the problems existing in traditional industries and the opportunities and challenges in the future, and illustrate the application prospect of real-time audio and video technology in traditional industries with cases.
