A Pay-TV System Using Audio Techniques
The Teleglobe System being tested in Denver, Colorado, under the authorization of the Federal Communications Commission, employs unique techniques in making use of regular telephone lines for simultaneously reproducing hi-fidelity audio program material and secret datalogging by centralized metering, as well as transmitting music and audio messages to subscribers in the day time about the Pay-TV programs of the evening. The application of regular telephone lines to provide audio security of the aural program material, which accompanies an unscrambled video broadcast, brings public utility discipline directly into the Pay-TV business. The discussion to follow will describe techniques used including the circuit arrangements by which these system features are accomplished in coordination with public utility installation and service procedures.
