  • Circuit for broadband video transmission over unshielded twisted wire pairs
    Patent number: 5420551
    Abstract: Disclosed is a circuit which permits transmission of broadband analog CATV video signals on unshielded twisted wire pairs. The circuit includes an autotransformer with a ground connection coupled to the node between two secondary windings. The two opposite ends of the secondary windings are coupled to a choke, which, in turn, is coupled to an isolation transformer with a center-tapped primary and secondary winding for shunting any remaining common-mode currents.
    Type: Grant

    Inventors: Robert A. Conte, William H. Georger
  • Adapter for transmission of color components on separate twisted wire pairs
    Patent number: 5389900
    Abstract: Disclosed is an adapter which permits transmission of red, green and blue video signals over separate unshielded twisted wire pairs. Crosstalk is minimized by wideband video chokes coupled to each signal input/output.

  • Adapter for video and audio transmission
    Patent number: 5367273
    Abstract: Disclosed is an adapter which permits unbalanced video and audio baseband signals to be transmitted over unshielded twisted pair wiring. The adapter includes low loss transformers which produce a minimum of crosstalk.

  • Autotransformer capable of passing a DC signal as well as a balanced output signal
    Patent number: 5363068
    Abstract: Disclosed is a series tuned resonant autotransformer which passes baseband video signals so that more than one non-synchronized channel can be sent over unshielded twisted pair wires sharing a common cable sheath. The transformer includes a trifilar winding configuration with a capacitor, resistor and ground connection coupled between the two secondary windings. The transformer is able to pass a DC signal as well as a balanced output signal over most of the video bandwidth.
