Dial a program—An HF remote selection cable television system

A new concept in cable television systems is described in which the general form of the network is similar to the local distribution network of a telephone system. Each television set is provided with an individual connection to a program exchange where the subscriber may select, by means of a remotely operated switch, the program of his choice from the unlimited number of programs available at the exchange. The system is based on the technology of HF multipair cable television systems extensively used in Great Britain. The system is flexible in use and the facilities for two-way transmission, subscription TV, audience rating, etc., are explained.
