Viewport-dependent 360 degree video streaming based on the emerging Omnidirectional Media Format (OMAF) standard

Abstract

360 degree video streaming has gained much interest recently. The Omnidirectional MediA Format (OMAF) standard, currently in development by the Moving Picture Experts Group (MPEG), standardizes means for storage and delivery of 360 degree coded video based on a well-established standards ecosystem. This demonstration system uses the viewport-dependent OMAF media profile in which visual content within the current viewport is transmitted and displayed in higher fidelity than content outside the viewport to exceed the visual fidelity of viewport-independent solutions. This is achieved by dividing the video frame into tiles and using HEVC motion-constrained tile set (MCTS) encoding at multiple resolutions.
