Title:
360-degree Video Standard and Streaming Technologies for Mobile Virtual Reality

Abstract:
These days 360-degree video processing technologies for virtual reality (VR) service are emerging. ISO/IEC MPEG and ITU-T VCEG are developing video standards for 360-degree video processing and file format together such as MPEG-I (Immersive media) and JVET Future Video Coding (FVC). Thus, this presentation introduces 360-degree video standard work and streaming technologies for mobile VR. It consists of three topics: (1) a new HEVC Tile allocation method considering the computational ability of asymmetric multicores as well as the computational complexity of each Tile. (2) 360-degree video standard work including the novel streaming technology that uses Motion-Constrained Tile Set (MCTS). The user viewpoint-based video tile streaming reduces bandwidth as well as the response time of user movement remarkably. (3) 360-degree video streaming over mmWave communication. The topic introduces the streaming strategies using raw video and entropy-coded raw video.
