ABSTRACT:
A selective receiving and/or recording technique for broadcast audio and/or video programs where the broadcast signal has a tone code preceding each program segment to which a monitoring-receiving-recording device is responsive, either matching the tone code with a prestored list of orders for receiving and/or recording that broadcast segment or responding to a particular code so as to disable its associated recorder to thus protect copyrighted information.
