Abstract: 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.

Abstract: A device includes one or more processors configured to obtain sound information from an audio source. The one or more processors are further configured to select, based on a latency criterion associated with a playback device, a compression mode in which a representation of the sound information is compressed prior to transmission to the playback device or a bypass mode in which the representation of the sound information is not compressed prior to transmission to the playback device. The one or more processors are further configured to generate audio data that includes, based on the selected one of the compression mode or the bypass mode, a compressed representation of the sound information or an uncompressed representation of the sound information. The one or more processors are also configured to send the audio data as streaming data, via wireless transmission, to the playback device.

Abstract: A server includes a processor configured to determine, based on reception of information from a client device, synchronization parameters between a server clock rate associated with the server and a client clock rate associated with the client device. The processor is also configured to determine a client-side generation timestamp for an audio frame based on the synchronization parameters and based on a server-side generation timestamp for the audio frame. The processor is further configured to generate the audio frame. The audio frame includes the client-side timestamp.

Abstract: Certain aspects of the present disclosure provide techniques for communicating time synchronized data between a client and a server. An example method generally includes synchronizing, by a client, a clock of the client with a clock source. The method also includes transmitting, from the client to a server, at an application level, information indicating the clock source, a cell identifier of a serving cell of the client, and accuracy of the clock source as a time value. The method further includes transmitting, from the client to the server, a message including data and a timestamp correlated to an event associated with the data based on the clock. The method also includes in response to the message, receiving, by the client from the server, generated data.

Abstract: The present disclosure relates to methods and apparatus for graphics processing. The apparatus can determine a combined depth map based on at least one of a 3DRU mesh, a DFS map, and a display pose. The apparatus can also determine one or more re-projected eye and depth buffers based on at least one of one or more eye buffers, one or more depth buffers, one or more bounding box and warp parameters, and the display pose. Further, the apparatus can communicate at least one composited frame based on the combined depth map and the one or more re-projected eye and depth buffers. The apparatus can also determine the at least one composited frame based on the combined depth map and the one or more re-projected eye and depth buffers. The apparatus can also combine the 3DRU mesh, the DFS map, and the display pose.

Abstract: 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.
