  • Patent number: 5850165
    Abstract: A method and system for distributing multimedia signals to a subscriber from a headend unit. The multimedia signals are transmitted on a network media as an RF signal. The RF signal is fed to an input terminal of a tap which has an RF circuit that splits the RF signal and distributes to an output terminal. The RF circuit splits the RF signals, and feeds the split signal to a plurality of connectors on the tap's front panel. The RF signals on the output terminal are fed downstream to a plurality of subscribers. A plate is placed in the tap such that when the RF circuit is removed for repair, maintenance or service, an electrical connection is maintained between the input and output terminal to prevent a disconnection of service downstream.

  • Patent number: 5781844
    Abstract: A method and system for distributing multimedia signals to a subscriber from a headend unit using a tap. The multimedia signals are transmitted on a network media as a composite RF and AC signal. A tap is upgraded by with a circuit that separates the AC from the RF signal in the composite signal. The separated AC signal is split in the upgraded tap. The RF signals are split in a circuit on the faceplate of the tap. The AC signal is fed to a power distribution unit which generates an AC output signal that is surge protected, RF filtered and current limited. The split RF signal and AC output signals are fed to connectors on the faceplate. By providing a tap where the AC and RF signal are separated in the same unit, the system can be upgraded with a power distribution unit when AC signals are required to supply power to subscriber equipment.

  • Patent number: 5581801
    Abstract: A method and system for distributing multimedia signals to a subscriber from a headend unit. The multimedia signals are transmitted on a network media as a composite RF and AC signal. A passive unit is upgraded by with a circuit having connectors that separates the AC from the RF signal. The signals are split in the upgraded passive unit. The AC signal is fed to a power distribution unit which generates an AC output signal that is surge protected, RF filtered and current limited. The RF signal and AC output signal are separately fed to a customer interface unit where the RF signal is decoded and transmitted to a subscriber. By providing a passive unit where the AC and RF signal are separated in the same unit, the system can be upgraded with a power distribution unit when AC signals are required to supply power to subscriber equipment.
