摘要： A sink device in a Wireless Display (WD) system may send performance information feedback to a source device to adjust media data processing at the source device. The performance information feedback may include performance indicators of the WD system that are capable of being measured or calculated at the sink device 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 and the sink device.

摘要： This disclosure relates to techniques to establish a multicast communication session between a source device and multiple sink devices in a Wireless Display (WD) system. Two or more sink devices may be interested in receiving the same media data from the source device. According to the techniques, the source device establishes a multicast session with the sink devices in the WD system, and sends a single copy of multicast media data for the multicast session to the interested sink devices using a receiving multicast port. The source device selects a receiving multicast port number as a destination identifier for each multicast session. The sink devices interested in receiving the media data of a given multicast session bind on the receiving multicast port for the multicast session. This disclosure describes several exemplary multicast subscription procedures to ensure correct binding on the receiving multicast port at each of the sink devices.

摘要： In one example, this disclosure describes a method that includes, in an example, determining, by a source device, that display data rendered by the source device comprises one or more displayable graphical objects. The method also includes in response to determining an event, selecting, by the source device, a set of the one or more graphical objects for rendering at a sink device. The method also includes generating, by the source device, configuration data based at least in part on the set of the one or more graphical objects, wherein the configuration data is usable by the sink device to render representations of graphical objects in the set of one or more graphical objects based at least in part on one or more display parameters associated with the sink device. The method also includes sending, by the source device, the configuration data to the sink device.
