ABSTRACT:
Methods and apparatuses for media playback system are disclosed, including a signal source for providing electrical signal representing media content; a processing unit for processing signal from the signal source; a distorting unit for introducing distortion to signal from the processing unit; a transducer for converting the electrical signal from the distorting unit to energy representing the media content; and a connection link for transmitting the signal from the distorting unit to the transducer. The arrangement protects media content against unauthorized duplication by ripping-off the transmitting signal.
