Abstract: Proposed is a system for providing video-based augmented reality content. The system may include a mobile device that transmits an image captured via a camera and IMU data, which is position and orientation information about the camera, and plays back received AR content. The image and the IMU data may be transmitted by being combined into a single image data packet. The system may also include a split rendering server that uses the image and IMU data of the image data packet of the mobile device to render a three-dimensional object, and provides the AR content, which is the rendered result, to the mobile device.

Abstract: A system and a method for split-rendering for persons with color weakness are proposed. The split-rendering method may include, by a service server, in response to a login of a user device, loading a color weakness profile corresponding to a user of the logging-in user device. The method may also include, by the service server, in response to the user being color-weak in accordance with the loaded color weakness profile, selecting one of a plurality of split-rendering servers. The method may further include, by the service server, transmitting a video content along with the color weakness profile to the selected split-rendering server, and by the service server, transmitting access information about the selected split-rendering server to the user device.

Abstract: An augmented reality (AR) streaming device interoperating with an edge server is proposed. The AR streaming device may include a sensing module including a camera and a certain inertia sensor, a display module streaming AR video, a communication module transmitting or receiving data to or from the edge server and the sensing module. The device may also include a memory and a processor executing a program stored in the memory. When image data and inertia data are obtained through the sensing module, the processor may perform synchronization and encoding on the image data and the inertia data to transmit to the edge server through the communication module. When segmentation rendering-processed AR video is received from the edge server, the processor may perform decoding and blending on the segmentation rendering AR video to perform control to be streamed through the display module.

Abstract: Proposed is a device for encoding a multi-channel image. The device may include a collection unit for collecting, in frame units, data of a plurality of capture cards. The device may also include an encoding unit which encodes the data collected in the collection unit, by using a plurality of encoders, and which encodes according to a configuration parameter defined regardless of the interface of the capture cards. The device may further include an output unit for outputting the encoded data.

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.
