Immersive 360° VR tiled streaming system for esports service

Abstract

This paper shows how a system was designed and implemented for the live tiled streaming of 360° Virtual Reality(VR) eSports based on HEVC. A virtual camera technique was designed and implemented based on the Unity and Unreal engines as a means of capturing 360° videos in a virtual space, and a MPEG-DASH SRD(Spatial Relation Description)[1-2] Based dashing and streaming server was configured to build a live HEVC encoding system and for real-time internet streaming. Finally, an integrated 360° VR client was configured for use as a multi-platform. Each technological element was designed to service the client through a 360° VR 3D stereo method, and the MPEG-DASH SRD was expanded such that high-quality game videos can be played at lower bandwidths.
