There are three regions when watching 360 VR video on HMD, which are Region of Interest viewer is watching, Non-Region of Interest, and shaded region. It is not efficient that streaming entire 360 VR video having over 8k resolution. In this paper, we extracted Field of View by using HMD Tracking and developed Low-Latency Tiled Streaming System based on MPEG-DASH SRD to improve efficiency of computing process and streaming bandwidth by rendering Region of Interest in high quality tiles and the rest of the regions in low quality tiles.
