  • Patent number: 3990012
    Abstract: A remote transceiver for a two-way cable television system includes a main receiving, transmitting and logic control unit coupled to a plurality of locally remote control units through a plurality of supplemental tuning and logic sections. A receiver in the main unit acts as the interface between the remote transceiver and a cable network through which interrogation, command and program signals generated from a central or master data station are received. The interrogation and command signals are fed to a main digital logic control section, which controls a transmitter for transmitting data via the cable network to the master station. The television program signals are coupled to a plurality of television receivers each through one of the supplemental tuning and logic sections. Each local remote control unit is coupled to one of the supplemental tuning and logic sections to control each television receiver independently and provide data from each locally remote location to the main digital section.
