QoE-based Video Communication over the Internet, Wi-Fi, LTE and 5G Networks; 360°/3DOF+ Video


Part 1: Modern video communication, including video streaming and interactive video communication, is playing an increasingly important role in our everyday life. In fact, it is estimated to account for as much as 70% of the total network traffic. In this talk, we look at the underlying technologies and various design approaches to optimizing the Quality of Experience (QoE) of the video. We cover a wide range of technologies, including the those commercially deployed such as DASH, WebRTC, Wi-Fi and LTE, and emphasize new technologies that come with 5G.

Part 2: The second talk presents a DASH based video streaming system that provides immersive user experience by enabling 360-degree and head motion parallax. The system consists of a server, a DASH client and a head tracker.

Part 3: Demo of 360°/3DOF+ Video Immersive Experience.

Liangping Ma of InterDigital Communications


QoE-based optimization for video communication over the Internet, Wi-Fi, LTE and 5G networks


Liangping Ma is a Member of Technical Staff with InterDigital, where he currently works on applied machine learning research, and previously was involved in 3GPP 5G NR standards activities and led the projects on Quality of Experience (QoE) based video communication. Prior to joining InterDigital in 2009, he was with San Diego Research Center and Argon ST (acquired by Boeing), where he designed and prototyped the baseband module of a modem for wireless sensor networks, and worked on policy-driven cognitive radios. He has published extensively on signal processing and communication. He has served as the IEEE Communication Society (SomSoc) San Diego Chapter Chair since 2015. He is an IEEE ComSoc Distinguished Lecturer (2017-2020), and has given many talks on 5G and video communication. He was on the organizing committee of International Conference on Multimedia and Expo (ICME) 2018. He teaches “Fundamentals of 5G NR” at UC San Diego Extension. He received his B.S degree in physics from Wuhan University, China, 1998 and PhD in electrical engineering from University of Delaware in 2004.

Yuwen He


QoE-based Video Communication over the Internet, Wi-Fi, LTE and 5G Networks


Yuwen He (M’03) received the B.S. degree in applied physics, and the M.E. and Ph.D. degrees in computer engineering from Tsinghua University, China, in 1998, 2000 and 2002, respectively.

He was with Dolby Laboratories Inc., Burbank, CA, USA; Panasonic Laboratories, Singapore; and Microsoft, Beijing, China. He has been involved in various video codec related research and developments, including 3D video coding, Blu-ray disc authoring system, transcoding, compound video coding and scalable video coding and transmission. He is currently with Innovation Labs, InterDigital Communications, Inc., Wilmington, DE, USA, as a senior Principal Engineer, where he manages the video standards and platforms team and leads video standards project. His research interests include video coding, signal processing, pattern recognition and immersive video applications. He is involved in Versatile Video Coding standardization and is 360Lib reference software coordinator in JVET.
