Abstract: A device includes one or more processors configured to receive, via wireless transmission from a playback device, data associated with a pose of the playback device. The one or more processors are also configured to select, based on the data, a particular representation of a sound field from a plurality of representations of the sound field. Each respective representation of the sound field corresponds to a different sector of a set of sectors. A sector represents a range of values associated with movement of the playback device. The one or more processors are further configured to generate audio data corresponding to the selected representation of the sound field. one or more processors are also configured to send, via wireless transmission, the audio data as streaming data to the playback device.

Abstract: A method and a system for warping a rendered frame is disclosed. On a host device of a split-rendering system, the method includes generating the rendered frame based on head tracking information of a user. The method also includes identifying a region of interest (ROI) of the rendered frame. The method also includes generating metadata for a warping operation from the ROI. The method further include transmitting the rendered frame and the metadata for a warping operation of the rendered frame. On a client device of the split-rendering system, the method includes transmitting head tracking information of a user by a client device. The method also includes receiving the rendered frame and metadata. The method further includes warping the rendered frame using the metadata and display pose information. The host device and the client device may be combined into an all-in-one head mounted display.

Abstract: Techniques and systems are provided for capturing images by a first device. For instance, a process can include obtaining a first image from a first camera, the first image being associated with a first capture time based on a first clock; mapping the first capture time to a second clock to obtain a second capture time, the second capture time based on a second clock, and wherein the second clock is based on a network time; associating the second capture time with the first image; obtaining a second image from a second camera of another device, the second image including a third capture time based on the second clock; determining phase delta information based on a time difference between the second capture time and the third capture time; and outputting the phase delta information to adjust a next capture time of at least one of the first or second camera.

Abstract: Systems and techniques are described herein for generating and/or processing virtual content in a distributed system (e.g., a distributed extended reality system). For example, a first device (e.g., a client device) of a distributed extended reality system may transmit one or more sets of pose prediction parameters (e.g., prediction coefficients, prediction time associated with raw pose data, and/or the raw pose data) to a second device (e.g., a server device) of the distributed extended reality system. The second device may predict one or more poses of the second device based on the set(s) of pose prediction parameters, and may generate virtual content based on a pose of the predicted pose(s) of the first device. The second may transmit and the first device may receive the virtual content. The first device may then display one or more virtual objects based at least in part on the received virtual content.

Abstract: Certain aspects of the present disclosure present a method of graphics processing at a wearable display device. The method generally includes rendering a first image based on a position of the wearable display device and contours and depth information for one or more real-world objects associated with the position, the rendered first image comprising, at least, one or more virtual objects, re-projecting the first image based on an updated position of the wearable display device that is different than the position, rendering a second image using re-projected contours of the one or more real-world objects in the first image, updated depth information for the one or more real-world objects in the first image, updated depth information for the one or more virtual objects in the first image, and warped one or more virtual objects, and displaying the second image on a display of the wearable display device.

Abstract: The present disclosure relates to methods and apparatus for graphics processing. Aspects of the present disclosure can render at least one frame including display content at a server. Aspects of the present disclosure can also downscale the at least one frame including the display content, where a downscaling rate of one or more portions of the at least one frame is based on a location of each of the one or more portions. Moreover, aspects of the present disclosure can communicate the downscaled at least one frame including the display content to a client device. Aspects of the present disclosure can also encode the downscaled at least one frame including the display content. Further, aspects of the present disclosure can decode the encoded at least one frame including the display content. Aspects of the present disclosure can also upscale the at least one frame including the display content.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a server device may receive, during a first time window, information indicating a plurality of client round-trip times (CRTTs) associated with a client device. The server device may compute a plurality of network round-trip times (NRTTs) based at least in part on the plurality of CRTTs, each NRTT in the plurality of NRTTs corresponding to a respective CRTT in the plurality of CRTTs. The server device may compute one or more NRTT metrics for the first time window using the plurality of NRTTs. The server device may selectively adjust a bitrate used for a transmission to the client device based at least in part on a determination of whether the one or more NRTT metrics satisfy one or more NRTT metric thresholds. Numerous other aspects are described.

Abstract: Systems and techniques are described herein for generating and/or processing virtual content in a distributed system (e.g., a distributed extended reality system). For example, a first device (e.g., a client device) of a distributed extended reality system may transmit one or more sets of pose prediction parameters (e.g., prediction coefficients, prediction time associated with raw pose data, and/or the raw pose data) to a second device (e.g., a server device) of the distributed extended reality system. The second device may predict one or more poses of the second device based on the set(s) of pose prediction parameters, and may generate virtual content based on a pose of the predicted pose(s) of the first device. The second may transmit and the first device may receive the virtual content. The first device may then display one or more virtual objects based at least in part on the received virtual content.
