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.

Abstract: This disclosure describes a method of transmitting media data from a source device, the method comprising establishing, with the source device, a first communication session between the source device and a sink device comprising a vehicle head unit, wherein the first communication session conforms to a communication protocol. The method also comprises discovering, with the source device and by the first communication session, the sink device. The method further comprises, during operation of the first communication session, establishing with the source device a second communication session between the source device and the sink device, wherein the second communication session conforms to a wireless display protocol. The method also comprises transmitting, using the second communication session, media data from the source device to the sink device for output to an interface of the sink device.
