Abstract: The disclosure relates to a low-power co-processor subsystem that can optimize power consumption in a wireless service platform having a main wireless application datapath, wherein the low-power co-processor subsystem may offload certain service discovery tasks from the main wireless application datapath (e.g., such that components residing therein can transition to a low-power state). For example, the service discovery tasks offloaded to the low-power co-processor subsystem may be determined according to protocol-specific service descriptions associated with one or more services to be provided and/or consumed at a wireless device. Furthermore, rules to wake the components in the main wireless application datapath may be dynamically defined and redefined or otherwise tuned to maximize the time that the components in the main wireless application datapath can spend in the low-power state and to determine conditions under which to selectively wake the components in the main wireless application datapath as needed.

Abstract: The various aspects provide methods, systems, and devices for coordinating the operating states of multiple SOCs within a computing device. Such coordination may be implemented through communication of information by the SOCs that represent advance notice of impending interactions between each other. The communicated information may be used by a recipient SOC for setting its operating state in advance of the potential impending interaction with another SOC. Accordingly, this technical improvement enables individual SOCs to preemptively influence the operating states of the other SOCs. For example, in the context of power management, the various aspects may coordinate the power states of multiple SOCs, thereby effectively implementing a monolithic power management state machine that improves overall power consumption of the computing device.

Abstract: Methods, systems, and devices are described for remote display of content in a wireless network. A source device capable of displaying content may identify one or more rendering instructions for content to be displayed remotely on a sink device. The source device may transmit the one or more rendering instructions to the sink device via a wireless peer-to-peer connection. The sink device may receive the one or more rendering instructions and may execute the one or more rendering instructions to render a display of at least part of the content. Further, the source device may receive data from the sink device via the wireless peer-to-peer connection. The identifying of the one or more rendering instructions by the source device may thus include identifying at least one rendering instruction based at least in part on the received data.

Abstract: Methods, devices, and computer program products for using raw bitstreams and lossless distributed source coded (DSC) video to optimize video performance in wireless dock with ultra-high definition displays. In one aspect, a method of transmitting a video stream from a transmitting device to a wireless video display is described. The method includes determining a resolution of the wireless video display and a native resolution of a video stream, as well as a connection speed between the transmitting device and the wireless video display. Based on this information, the method selects a video compression format, choosing between raw video, DSC video, and high-efficiency video coded video. The method further transmits the video stream in the selected video compression format from the transmitting device to the wireless video display.
