  • Decoder mode validation apparatus for pay television systems
    Patent number: 4091417
    Abstract: A predetermined pattern of code signals is periodically inserted into the transmitted encoded television signal. The pattern is so chosen that a bistable circuit at the receiver changes state for each received signal. A counter counts the number of state changes and, if correct, a validation signal is furnished. The validation signal allows recording of the billing charge for the program and transmission of the decoded signal to the television receiver.
