    Abstract: Esta descripción describe un método de transmitir datos de medios desde un dispositivo fuente, el método comprende establecer, con el dispositivo fuente, una primera sesión de comunicación entre el dispositivo fuente y un dispositivo receptor que comprende una unidad principal del vehículo, donde la primera sesión de comunicación se ajusta a un protocolo de comunicación. El método también comprende descubrir, con el dispositivo fuente y mediante la primera sesión de comunicación, el dispositivo receptor. El método también comprende, durante la operación de la primera sesión de comunicación, establecer con el dispositivo fuente una segunda sesión de comunicación entre el dispositivo fuente y el dispositivo receptor, donde la segunda sesión de comunicación se ajusta a un protocolo de pantalla inalámbrica. El método también comprende transmitir, usando la segunda sesión de comunicación, datos de medios desde el dispositivo fuente al dispositivo receptor para la salida a una interfaz del dispositivo receptor.

    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.
