L'adaptateur d'interface de bus de données-ligne électrique établit une interface avec le réseau d'alimentation électrique, et module et transmet des signaux de données, tels que des signaux MP3, sur ledit réseau d'alimentation électrique. Le système comprend également un adaptateur d'interface de ligne électrique-équipement audio. L'adaptateur d'interface de ligne électrique-équipement audio établit une interface entre le réseau d'alimentation électrique et l'équipement audio, et reçoit et démodule les signaux reçus sur ledit réseau d'alimentation électrique.
