<p>A wireless transmission system (100) for audio data consisting of a portable electro-acoustic transducer set (101) and a plurality of media sources (102) providing audio data is proposed, with the portable electro-acoustic transducer set (101) being adapted to transmit and to receive control data and audio data over an air interface, and each of the plurality of media sources (102) being adapted to transmit and to receive control data and audio data to and from the portable electro-acoustic transducer set, whereby the portable electro-acoustic transducer set (101) comprises means for selectively establishing a link with one of the media sources (102) for a bi-directional transmission of audio and control data. The portable electro-acoustic transducer set comprises retrieving means (130, 131) for retrieving information from a plurality of media sources (102), storage means (133) for storing information retrieved from the plurality of media sources (102), transducer means (110) for acoustically reproducing information retrieved from the plurality of media sources (102), and input means (132) for selecting a media source (102) from the plurality of media sources (102), whereby the retrieving means (130, 131) establishes a selective bi-directional transmission link with a media source (102) selected by the input means (132) based on information retrieved from the media source (102). A media source (102) comprises a transceiving means (140) for transmitting and receiving control data and audio data to and from a portable electro-acoustic transducer set (101) via an air interface, whereby once a selective link is established between the media source (102) and a portable electro-acoustic transducer set (101), the media source (102) exchanges audio and control data exclusively with that portable electro-acoustic transducer set (101). <IMAGE></p> |
