An integrated circuit interface means for use in a television receiver comprises means including an interface terminal which gives an indication of whether the receiver is operating in a standard or nonstandard mode. Standard operating mode occurs during the reception of standard broadcast signals. Non-standard non-broadcast signals cause the receiver to operate in a non-standard mode. The interface means also comprises means coupled to the same interface terminal for providing a signal to the integrated circuit which manually selects the operating mode, thereby allowing the interface terminal to serve the dual function of indicating and selecting the receiver operating mode.
