The third major generation of immersive communication is upon us. The first two generations, the telephone and the television, have long been firmly embedded in the fabric of society. The third generation is now revealed to us in the form of Augmented and Virtual Reality (AR/VR). However, unlike voice and video, as of yet there is no commonly agreed upon paradigm for its format, never mind how to code it. In this talk, I will discuss candidates for how to represent AR/VR, and how to code it. Graph Signal Processing emerges as an important toolset for representing, coding, and processing AR/VR.

Bio: Philip A. Chou is a Principal Researcher at Microsoft Research. He received a BSE from Princeton, MS from Berkeley, and PhD from Stanford. He was a Member of Technical Staff both at AT&T Bell Laboratories and the Xerox Palo Alto Research Center. He was Affiliate Faculty at Stanford University, the University of Washington, and the Chinese University of Hong Kong. He was Manager at the startup VXtreme (later acquired by Microsoft) where led the compression team for the first commercial video on demand over the Internet. Key ideas in video compression today have come from his work, including rate-distortion optimization, multiple reference frame coding, tree-structured coding, and multiple bit rate streaming. He is a Fellow of the IEEE.
