Abstract
A pay-per-view CATV system which is interfaced with the switched public telephone system is described. A subscriber selects a specific scheduled television event by dialing a telephone number which uniquely identifies the selected event. The called and originating numbers are identified, digitized and combined to form a digital word. The digital word is then transmitted to the CATV supplier.
