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 buffering at the sink devices based on application awareness for the media data. The techniques include learning the type of application for the media data, and adjusting the size of buffers in the processing pipeline to achieve an appropriate balance between smoothness and latency for the application type. For example, when the media data is for a video playback application, the techniques include increasing the buffer size to increase smoothness in the video playback application.

Abstract: A method of transmitting universal serial bus (USB) frames over a communications channel is disclosed. A USB device receives one or more USB frames from a host device via a network, wherein the one or more USB frames are encapsulated in one or more data packets based on a communications protocol associated with the network. The USB device further synchronizes a local clock signal with a clock signal of the host device using a clock synchronization mechanism of the communications protocol. The USB device then determines a number of USB frames transmitted by the host device and processes the one or more USB frames based, at least in part, on the synchronized local clock signal. For some embodiments, the USB device may receive a frame count value and a corresponding media time value from the host device.

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.

Abstract: A method and apparatus are disclosed for transferring data through a shared communication medium between communication devices. In at least one embodiment, a timeout period used to detect data transfer errors may be modified based, at least in part, on a data transfer status message transmitted from a media access control (MAC) layer to a protocol adaptation layer of a first communication device. The data transfer status message may include a status and an expected duration of a pending data transfer. In another embodiment, The timeout period may be modified based, at least in part, on data transfer statistics transmitted from the MAC layer to the protocol adaptation layer. Data transfer statistics may be accumulated by the MAC layer and may include data transfer size, data throughput rates, and number of re-attempted data transfers.
