Abstract
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.
