A wideband video system transmits and receives video signals through a ground line of a power distribution network. This single line transmission path is not susceptable to noise signals as is a dual line transmission path. The single line transmission path is grounded in the transmitter by a cable from an incoming source and also grounded in the receivers by respective monitors. Between the incoming source and the monitors, a single communication line carries single ended wide band video signals respecting floating grounds through the transmitter, the ground line and the receivers. This single line transmission is less susceptible to noise on the power lines thereby enabling the transmission of up to 500 mHz signals suitable for video transmission over a wide frequency band.

A power line communication system for communicating wide band video signals between an incoming source having dual line outputs and at least one receptor having dual line inputs, over a single line within a power distribution network, comprising: a transmitter for receiving said video signals from said dual line outputs and for presenting said signals onto said single line, and a receiver for receiving said signals on said single line, and for presenting said signals onto said dual line inputs, said transmitter and receiver having grounds which are isolated from said single line.
