The invention concerns an audio/video signal distribution system, comprising audio/video signal sources (MGT, DVD, C, HIFI) and audio/video signal receivers (TV1, TV2, TV3, TV4), and a central processing and multiplexing unit (MDS, MDS'). The invention is characterized in that it comprises a twisted pair service network (PS) for routing said audio/video signals from the sources to the processing and multiplexing unit and a twisted pair distribution network (P, D) for routing the processed multiplexed audio/video signals from the processing and multiplexing unit to the receivers.
