Abstract
A low-latency 360 virtual reality (VR) streaming method for estimating a region of interest (ROI) of a user is proposed. The method may include receiving device pose information from a user device, extracting an ROI of a user, based on the device pose information, and generating ROI tile information corresponding to the ROT. The method may also include generating ROI estimation tile information corresponding to a position at which the ROI is to be changed, and requesting, from a streaming server, a tile corresponding to the ROI tile information and the ROI estimation tile information to receive a high-quality tile stream and a low-quality tile stream of full video that includes a low-quality full video tile stream. The method may further include decoding and rendering the high-quality tile stream and the low-quality full video tile stream and providing the rendered video to the user device.
