Abstract: Methods, devices, systems, and non-transitory process-readable storage media for scalable data service distribution in WiFi Miracast. A processor of a source computing device in a WiFi Miracast network may group all sink computing devices scheduled to receive a frame or packet of a service into a single multicast group and transmit a multicast frame or packet to the sink computing devices. Individual sink computing devices in a WiFi Miracast network may be configured to send error logs indicating the quality of their respective wireless connections with a source computing device to the source computing device. A source computing device may add multicast group member sink computing devices to a unicast group based at least in part on missing and/or received error logs from the multicast group member sink computing devices.

Abstract: Techniques of this disclosure are generally directed to a method of transmitting content of a first wireless computing device to a second wireless computing device. A first wireless computing device may initiate a WI FI display (WFD) connection transmit data from the first wireless computing device via the WFD connection to the second wireless computing device execute a media sharing application that enables the first wireless computing device to share a media item of a playlist with a wireless client computing device transmit information that describes the media item of the playlist to the wireless client computing device wherein transmitting the information that describes the media item causes the second wireless computing device to determine if the wireless client computing device is capable of outputting the media item and transmit the media item to the wireless client computing device.

Abstract: 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).

Abstract: 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.
