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: An extensible hub is disclosed for providing multi-hop wireless communication among universal serial bus (USB) devices, for example, utilizing a WiGig Serial Extension (WSE) air interface. The extensible hub may include a device protocol adaptation layer (PAL), as well as a host PAL, and further a bridge for providing a data flow path between the device and host PALs. The bridge may be configured to distinguish between request messages and response messages in accordance with a header on those messages. Further, the extensible hub may include virtual ports and may map device handles and endpoint handles to provide for routing of messages to the correct downstream devices in a multi-hop network tree.

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 low latency screen capture and buffering at the source device. For example, a processing pipeline of the source device may be configured to include minimum-size buffers between processing steps to reduce latency. The techniques include buffering a most recent frame update captured from the media data in the minimum-size buffers and dropping older frame updates when the minimum-size buffers are full. In addition, the processing pipeline may be configured to use hardware acceleration to retrieve the frame updates from the buffers for processing.
