A communication system which supplements a hotel's in-house cable or off-air TV signal distribution network for permitting locally originated video messages, which may be commercial in nature, to automatically interrupt the regular TV signals on each of the TV receivers in the rooms of the hotel. The local signal may be generated by means of pre-recorded tapes played on a video tape player or, alternatively, may be generated from a live broadcast using a TV camera located, for example, in the lounge of the hotel. The locally generated TV signal, which is of a predetermined frequency, is frequency converted into as many frequencies as may be received by the TV receivers in the hotel establishment. An electronic timer may automatically and periodically interrupt the regular TV signals being received with the locally generated signal for a predetermined time period which may be set, for example, to correspond with the regular network commercial interruptions.
In combination with a TV signal distribution system in a hotel or similar facility wherein externally originated TV signals of a plurality of different predetermined frequencies are fed to a plurality of TV receivers located in the rooms of the hotel or the like, each said TV receiver being capable of receiving one of said TV signals at a time, apparatus which comprises:
A method of automatically providing locally originated TV signals to a plurality of TV receivers normally adapted to receive a plurality of externally generated different frequency signals via a locally installed signal distribution system comprising the steps of:
For use in a TV signal distribution system in a hotel or other similar facility, wherein externally originated TV signals of discrete different predetermined frequencies corresponding to TV channels are each fed to each of a plurality of TV receivers, a system for substituting a locally originated TV signal on each of said predetermined frequencies comprising:
