ABSTRACT:
A television signal distribution system for special programs in an establishment, as a motel, with plural receivers. A master antenna is connected through a cable distribution system with each of the receivers. Special program signals, as of a movie, are distributed through the cable on an unused channel. A filter at each receiver blocks the special signal from the receiver. A circuit actuated from a central control station is directed to the room over the telephone system and disables the filter enabling the occupant of the room to watch the special program.
