摘要： Techniques and systems are provided for light estimation. In some examples, a system receives a plurality of frames associated with a scene. The plurality of frames includes a first frame and a second frame occurring after the first frame. The system determines, based on image data of the first frame, a first light estimate associated with the scene. The system also determines, based on image data of the second frame, a second light estimate associated with the scene. The system further generates an aggregate light estimate associated with the scene based on combining the second light estimate with at least the first light estimate.

摘要： Methods, devices, and apparatuses are provided to facilitate a positioning of an item of virtual content in an extended reality environment. For example, a placement position for an item of virtual content can be transmitted to one or more of a first device and a second device. The placement position can be based on correlated map data generated based on first map data obtained from the first device and second map data obtained from the second device. In some examples, the first device can transmit the placement position to the second device.

摘要： An improved wireless split rendering system for displaying Extended Reality (XR) content is discussed. A rendering server and client head-mounted device (HMD) may communicate over a wireless medium, where communication control is given to a server application layer logic. This allows the server to use request pose information from the HMD only when needed for rendering, while preserving bandwidth on the wireless medium for transmitting frames of the rendered content. This reduces contention and improves channel efficiency.

摘要： Methods, devices, and apparatuses are provided to facilitate a positioning of an item of virtual content in an extended reality environment. For example, a first user may access the extended reality environment through a display of a mobile device, and in some examples, the methods may determine positions and orientations of the first user and a second user within the extended reality environment. The methods may also determine a position for placement of the item of virtual content in the extended reality environment based on the determined positions and orientations of the first user and the second user, and perform operations that insert the item of virtual content into the extended reality environment at the determined placement position.

摘要： Methods, systems, and devices for frequency synchronization and phase correction at a rendering device are described. One method may include receiving, from a display device (e.g., a head-mounted display (HMD) device), a vertical sync count and an indication of one or more frame repeats. The rendering device may estimate a vertical sync frequency based on the received vertical sync count, and determine a phase corresponding to a minimum frame repeat based on the indication of the one or more frame repeats. The rendering device may adjust a vertical sync frequency to the estimated vertical sync frequency and a phase to the determined phase. The rendering device may transmit one or more frames to the display device using the adjusted frequency and/or the adjusted phase.

摘要： The present disclosure relates to methods and apparatus for video processing. In one aspect, the apparatus may configure at least one frame of plurality of frames in a video stream. The apparatus may also divide the at least one frame into one or more slices, each of the one or more slices including one or more data packets. The apparatus may also map each of the one or more slices to one of one or more communication channels. The apparatus may also transmit each of the one or more slices including the one or more data packets via the one of the one or more communication channels. In another aspect, the apparatus may receive each of one or more slices via one of one or more communication channels. The apparatus may also decode each of the one or more slices including one or more data packets.

摘要： Methods and systems for providing software applications on a client device with dynamic control over low-latency mode (LLM) operations of the client device. The client device may monitor downlink data packets of a client software application operating on the client device to detect trigger events. The client device may determine operating parameters of the modem based on a detected trigger event and dynamically adjust the low-latency mode of the modem based on the detect trigger event or the determined operating parameters.
