Wireless streaming media systems, devices and methods

A system comprising:

• at least one transmitter unit constructed and configured to transmit wireless streaming media to detected ones of one or more receiver units,
• the transmitter unit including:
• plural external ports for communication with automatically detected plural differently-formatted streaming media video sources delivering source video in respectively different video formats, the transmitter unit configured to automatically detect a type of the different video formats from the differently-formatted streaming video sources;
• a digital video signal processor transforming the source video into video information, converting the video information into one of a plurality of available video protocols, and preparing the video information for wireless transmission to the detected ones of the receiver units;
• and
• the transmitter unit constructed and configured to automatically detect which receiver units are operating in an operational range and, if the number of the receiver units in the operational range is one, automatically establishing a point-to-point wireless communications channel to send the video information to the one of the receiver units, and if the number of other receiver units is more than one, automatically establishing a point-to-multipoint communication broadcast to send the video information to the more than one receiver units in the operational range, the transmitter unit also constructed and configured to automatically detect when changes occur to the number of receiver units in the operating range and accordingly change the point-to-point or point-to-multipoint communication.
