1. A method comprising:
- activating a first wireless communication interface supporting a predetermined audio distribution profile of a point-to-point media data communication interface and performing an inquiry to find other wireless devices supporting the predetermined audio distribution profile of the point-to-point media data communication interface;
determining via operation employing the first wireless communication interface, an absence of other wireless devices supporting the predetermined audio distribution profile of the point-to-point media data communication interface;
activating a second wireless communication interface capable of media broadcast, in response to the determination of the absence of other wireless devices;
determining, via operation employing the second communication interface, at least one unoccupied media broadcast frequency;
determining to automatically select a one of said unoccupied media broadcast frequencies; and
determining to media broadcast the media data, via the second communication interface, using the automatically selected frequency.
