Abstract: Aspects of the present disclosure relate to graphics domain transmission methods that utilize an adaptive compression pipeline to achieve low latency screen mirroring between a source device and a sink device. A source device captures a plurality of graphics domain frames, each of the graphics domain frames including one or more graphics command tokens. The source device utilizes an adaptive compression pipeline to compress the graphics domain frames based on one or more characteristics of the frames, and the adaptive compression pipeline is configured to perform at least one of scalable texture streaming, frame-based prediction, frame dropping, or data compression. The source device transmits the compressed frames to a sink device, and displays a rendered image of the graphics domain frames in time synchronization with a corresponding rendered image of the compressed frames displayed at the sink device.

Abstract: This disclosure describes techniques to improve a user experience in a Wireless Display (WD) system. The WD system includes a source device that provides media data to one or more sink devices. The techniques are directed toward reducing end-to-end latency in the WD system while improving video playback quality at the sink devices. More specifically, the techniques include customized playback at the sink devices based on the type of media data received from the source device. If the media data only includes video data and does not include audio data, a processing pipeline of the sink device is configured to render the video data without waiting to synchronize with non-existent audio data. If the media data includes both video data and audio data, an audio rendering start-up timer is reduced and the processing pipeline renders synchronized audio and video data according to the reduced start-up timer.

Abstract: This disclosure describes wireless communication techniques, protocols, methods, and devices applicable to a docking system environment in which aspects of wireless docking may function using vicinity-based undocking techniques. In some examples, the techniques of this disclosure enable a wireless docking center to undock a wireless dockee in a situation where a wireless dockee moves out of the vicinity of a wireless docking center so as to prevent malicious users from using peripheral devices available through the wireless docking center to interact with the wireless dockee without the wireless dockee user's knowledge. In other examples, the wireless dockee may undock itself from a wireless docking center when the wireless dockee moves out of the vicinity of a wireless docking center.
