ABSTRACT:
A television receiver is adapted for use of standardized plug-in descramblers which are coupled to the receiver by a connector. The connector is accessible from the exterior of the housing of the receiver without significant disassembly. The connector has terminals electrically coupled to various key points in the receiver. Each type of descrambler is adapted for descrambling a particular type of scrambled signal, and for that purpose uses certain of the connector terminals. The plug-in descrambler also selects the operating frequency characteristics of the tuner.
