摘要： Various aspects of the present disclosure enable a docking host that manages a docking environment to establish an initial connection between the docking host and one or more wireless peripheral devices to perform functionality determination of the wireless peripherals devices. The docking host may store the results of the functionality and, upon receiving a request from a dockee to access the functionality that the docking host may provide, will update the results. In one aspect of the disclosed approach, the docking host may determine the current state of the wireless peripheral devices before advertising any functionality information to the dockee. Other aspects, embodiments, and features are also claimed and described.

摘要： A sink device (160) in a Wireless Display (WD) system (100) may send performance information feedback to a source device (120) to adjust media data processing at the source device (120). The performance information feedback may include performance indicators of the WD system that are capable of being measured or calculated at the sink device (160) based on received media data or request to adjust the transmission of media data. For example, the performance information feedback may include one or more of round trip delay, delay jitter, packet loss ratio, error distribution, and received signal strength indication (RSSI). The feedback channel may be piggybacked on a reverse channel architecture referred to as the User Input Back Channel (UIBC) implemented between the source device (120) and the sink device (160).

摘要： As part of a communication session, a wireless source device can transmit audio and video data to a wireless sink device, and the wireless sink device can transmit user input data received at the wireless sink device back to the wireless source device. In an aspect, this includes receiving, by the wireless source device, a data packet from the wireless sink device, the data packet comprising a data packet header and payload data, parsing, by the wireless source device, the data packet header for a four-bit input category field and a timestamp flag that indicates whether the data packet header includes a sixteen-bit timestamp field, in response to the timestamp flag indicating that the data packet header does include the timestamp field, parsing, by the wireless source device, the data packet header to identify, based on a representation of a timestamp included in the timestamp field, a particular frame of video data that was displayed by the wireless sink device while user input data was captured and processing, by the wireless source device, the payload data based at least in part on the identified particular frame of the video data.

摘要： As part of a communication session, a wireless source device can transmit audio and video data to a wireless sink device, and the wireless sink device can transmit user inputs received at the wireless sink device back to the wireless source device. In this manner, a user of the wireless sink device can control the wireless source device and control the content that is being transmitted from the wireless source device to the wireless sink device. As part of transmitting user input to the source device, the sink device can generate a data packet with a data packet header that includes a timestamp field, and the source device can process the data packet based on a timestamp in the timestamp field.

摘要： As part of a communication session, a wireless source device can transmit audio and video data to a wireless sink device, and the wireless sink device can transmit user input data received at the wireless sink device back to the wireless source device. In this manner, a user of the wireless sink device can control the wireless source device and control the content that is being transmitted from the wireless source device to the wireless sink device. The input data received at the wireless sink device can have associated coordinate information that is scaled or normalized by either the wireless sink device or the wireless source device.
