ABSTRACT:
Video programming signals from a broadband source are distributed on installed telephone wiring to the individual units of a commercial structure or multiple unit dwelling. In all methods and associated devices a first transponder device centrally located in a utility space is paired with a second terminal transponder device located on a telephone subscriber premises. The devices cooperate in converting a video signal into a form suitable for transmission on telephone lines and deconverting that signal into a form suitable for reception by consumer video equipment. The methods and devices discussed differ in placement of the central device, and in the particular method of signal conversion.
