A system ( 200 ) for distributing audio and video signals including a source location ( 202 ) having one or more devices ( 204, 206, 208, 210 ) producing an audio signal and an analogue video signal is provided. At least one display and audio receiver ( 222 ) at a remote location ( 220 ) is also provided and a single cable ( 100 ) including at least three unshielded twisted pairs ( 102, 104, 106 ) is operably connected between the source location ( 200 ) and the at least one remote display and audio receiver ( 222 ) with the cable ( 100 ) transmitting the source signals to the display and audio receiver ( 222 ) at the remote location ( 202 ). The analogue video signal is converted to a balanced signal before transmission from the source ( 202 ) to the remote location ( 220 ) over a first twisted pair ( 102 ) and reconverted to an unbalanced signal at the remote location ( 220 ). The audio signal is transmitted over a second twisted pair ( 104 ) to the remote location ( 220 ) and a control signal for controlling the source signals from the remote location ( 220 ) is transmitted on a third twisted pair ( 106 ) to the source location ( 202 ).
