LOW-LATENCY 360 VR STREAMING SYSTEM AND METHOD FOR ESTIMATING REGION OF INTEREST OF USER - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240283901 titled 'LOW-LATENCY 360 VR STREAMING SYSTEM AND METHOD FOR ESTIMATING REGION OF INTEREST OF USER

The abstract describes a method for low-latency 360 virtual reality (VR) streaming that estimates a region of interest (ROI) of a user based on device pose information.

• Receiving device pose information from a user device
• Extracting an ROI of a user based on the device pose information
• Generating ROI tile information corresponding to the ROI
• Generating ROI estimation tile information for changing the ROI position
• Requesting high-quality and low-quality tile streams from a streaming server
• Decoding and rendering the tile streams for the user device

Original Abstract Submitted

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.
