  • Patent number: 4325078
    Abstract: An apparatus and method for providing limited access to broadcast television programming in a CATV System wherein each television subscriber is provided with a converter for converting broadcast television signals into signals suitable for reception and display by a conventional television receiver and means for disabling the converter from producing TV compatible signals selectively activated by a switching device. A magnetic card reader reads the data on a program card inserted by the subscriber and compares it with a reference data record stored in a memory to determine if the program card is valid for the program sought to be viewed. If the card is valid a timer is actuated to cause the switching device to enable reception of the broadcast program while obliterating the data on the program card so that the card cannot be reused. The reference data record may be variable with time so that a program card will only be effective for enabling program viewing during a predetermined time period.
