Abstract: In various aspects a host processor and a touchscreen controller may concurrently process a signal sent by a touch transducer when a touch is detected. A touch signal sent directly from a touch transducer may be formatted into a calibrated touch signal that the host processor can process. The calibrated touch signal may allow the host processor to receive and process touch signals from transducers and touchscreens from various manufacturers. The touchscreen controller and the host processor may each independently assess the touch-processing state. The touch-processing state may be set to one of a plurality of “states,” and the plurality of states may have rules for transitioning between the states. In various aspects, a host processor and a touchscreen controller may dynamically set, among other things, the scanning rate and resolution of a touchscreen panel based on the touch-processing state.

Abstract: A receive device receives video data in the form of an encoded video bit stream. A video decoder of the receive device identifies a portion of the video data corresponding to a first scene and determines a complexity for this first scene and also determines a quality of service for the receive device. If the complexity of the first portion of video data is greater than a complexity threshold value or the quality of service is less than a quality of service threshold value, then the video decoder uses a hardware accelerator to decode the portion of video data. If, however, the complexity of the portion of video data is less than the complexity threshold value and the quality of service is greater than the quality of service threshold value, then the video decoder may use software decoding to decode the portion of video data.

Abstract: In general, this disclosure relates to techniques for management of email access for a wireless communication device (WCD). The techniques may utilize an email access manager that selects a synchronization mode to synchronize with a remote email server and selects a transfer mode to transfer email messages with the remote email server based on context data regarding the WCD. The context data of the WCD may include one or more of quality of service (QoS) of network connections with the remote email server, battery status of the WCD, and user settings for the WCD. The email access manager monitors the context data from one or more managers, applications, and/or memory within the WCD. The techniques described herein enable an email application on a WCD to dynamically alter synchronization and transfer of email messages with a remote email server as appropriate given the context of the WCD.

Abstract: A source device in a wireless display system determines whether a scene change has occurred between a first picture and a second picture prior to transmitting an encoded representation of the second picture to a sink device. The scene change occurs when the first picture and the second picture are sufficiently dissimilar. The source device may reduce, in response to determining that the scene change has occurred, a number of coding bits in the encoded representation of the second picture. Furthermore, in response to determining that the scene change has occurred, the source device increases a throughput of a wireless channel. After reducing the number of coding bits in the encoded representation of the second picture and increasing the throughput of the wireless channel, the source device transmits the encoded representation of the second picture to the sink device via the wireless channel.

Abstract: A method for determining touch input data complexity and negotiating the processing of touch inputs from a touchscreen controller to a host processor. As touch input data is received from a touchscreen, the data may be evaluated by the touchscreen controller to determine the data's complexity. When the touchscreen controller determines the received touch input data is too complex for touchscreen controller processing, the host processor may be requested to process the data. The touchscreen controller may resume processing touch input data based on low complexity or host processor availability. Complexity may be determined based on evaluations of the number and frequency of touch inputs. Additionally, the touch input data may be evaluated to determine whether it represents multi-touch input. In an aspect, the touchscreen controller may disregard received touch input data determined to be noise.

Abstract: Various embodiments of methods and systems for managing battery load in a portable computing device (“PCD”) are disclosed. One such method includes tracking an active load on a battery attributable to one or more active power consuming components. Measurements associated with the battery and indicative of the battery's state of health may also be monitored. When a call for additional load on the battery is recognized, such as a user request for provision of additional functionality in the PCD, a future load on the battery that considers the newly called load can be calculated. Based on an analysis of the impact on the battery's state of health, existing, lower priority loads may be scaled or suspended to create battery load capacity for the newly called load. In this way, quality of service and user experience may be optimized while minimizing conditions that could be detrimental to the battery.

The display device may read the modified image data from memory to present the static image, which may reduce power consumption of the display device.

Abstract: This disclosure relates to techniques for performing display mode based video encoding to reduce power consumption in a source device of a Wireless Display (WD) system. More specifically, the techniques enable the source device to select an encoding process based on whether the video data to be encoded is in a static display mode or a dynamic display mode. For example, when the video data is in the static display mode, the source device selects a static encoding process that reduces an amount of video data processing and compression, which in turn reduces power consumption at the source device. When the video data is in the dynamic mode, the source device may select a conventional dynamic encoding process. The source device encodes the video data according to the selected encoding process, and transmits the encoded video data to one or more sink devices in the WD system for display.

Abstract: In general, this disclosure relates to techniques for management of a multimedia connection between a wireless communication device (WCD) and one or more output devices. The connection may be a multimedia interface connection with content protection, e.g., High Definition Multimedia Interface (HDMI). In some cases, the multimedia interface connection with content protection may be inactive because the output device is no longer connected or the multimedia application is stopped or paused. The techniques include detecting a use mode of the multimedia interface connection with content protection between the WCD and one or more output devices. When the use mode of the multimedia interface connection with content protection is inactive, the WCD may reduce at least one of content processing or content protection processing. In this way, the techniques may reduce battery power consumption from multimedia processing by the WCD.

A display processor may retrieve the reduced spatial resolution version of the static image from local memory. The display processor may rescale the reduced spatial resolution version of the static image, and display the rescaled image on a display for presentation.
