Abstract: Methods and apparatus for graphics processing, such as producing a smooth transition between images of different dynamic ranges (e.g., Standard Dynamic Range (SDR) images and High Dynamic Range (HDR) images). An example method generally includes using a high frame rate during a transition period to allow properties of images to incrementally vary. The properties may include brightness (i.e., luminance), color gamut, tone mapping, among others. For example, during the transition period, a subset of HDR images are displayed at a second frame rate (e.g., 120 Hz) higher than a frame rate based on the HDR images (e.g., 30 Hz). Simultaneously, a brightness level (as well as other aspects) of the display panel is adjusted incrementally from an SDR brightness level to an HDR brightness level during the transition time period over the subset of the HDR images.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that one or more threshold criteria are satisfied, wherein the one or more threshold criteria include at least one of a first value for an uplink grant rate, a second value for a buffer size, or a third value for a packet data convergence protocol discard rate, wherein the one or more threshold criteria relate to a network condition with less than a reference uplink throughput and greater than a reference downlink throughput. The UE may transmit information identifying one or more adjusted measurement values based at least in part on the determination of the one or more threshold criteria. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are disclosed by the present application. A request to establish a call using a first connection may be received, the first connection using a first radio access technology to communicate with a radio access network. During execution of a procedure to establish the call, a command to handover communications from the first connection to a second connection that uses a second radio access technology to communicate with the radio access network may be received. The second connection may be established in response to the command, and a message indicating that the request to establish the call was successfully received may be transmitted over the second connection. Also, a message indicating that an alert of the call is being issued may be transmitted over the second connection.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for composition strategy searching based on dynamic priority and runtime statistics. A CPU may determine, based on a plurality of frames, a usage frequency of each of one or more composition groups. The one or more composition groups may be used for composing the plurality of frames. The CPU may subsequently assign/update a priority for each of the one or more composition groups based on the usage frequency, such that the CPU may analyze, as part of a frame composition procedure, at least one of the one or more composition groups in an order that is based on the priority of the one or more composition groups.

Abstract: A device includes one or more processors configured to obtain output delay data based on a transmission from an audio output device. The output delay data indicates a playback delay associated with audio output by the audio output device. The one or more processors are further configured to determine, based on the output delay data and host delay data, a synchronization delay to coordinate audio output by the audio output device and video output at a display. The one or more processors are further configured to initiate sending of audio data to the audio output device and to send video data to the display. The video data is delayed, based on the synchronization delay, relative to the sending of the audio data.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to network slicing enhancements with randomly generated application identifiers. For example, by handling requests of an application, a user equipment (UE) may be able to forward such requests to a network entity to receive an encoded random number token corresponding to the application to provide for improved indexing of applications on the UE.

Abstract: Systems, methods, and non-transitory media are provided for dynamically switching frame rates without changing a display refresh rate. An example method can include receiving, from a display device associated with a computing device, a set of control signals indicating a display refresh rate implemented by the display device; adjusting a frame rate associated with application data from one or more applications executed on the computing device; synchronizing, based on the set of control signals, the adjusted frame rate with two or more display refresh cycles, each display refresh cycle being based on the display refresh rate; providing, to the display device, a first frame at the adjusted frame rate, the first frame being generated based on the application data; and displaying the first frame at the display device implementing the display refresh rate.
