ABSTRACT:
The present invention enhances user friendliness of a system which is controlled by use of on-screen display by disabling the operation of these devices if it not permitted. According to the invention, when a recording of a received program is attempted, the program is checked for copy protection. If the program is found copy protected, a warning thereof is displayed and control of a recording/reproducing device concerned is disabled. This warning display allows the user to determine whether or not a program being received is copy protected beforehand, thereby preventing the video signal containing a copy protection control signal from being recorded on the recording/reproducing device. In addition, according to the invention, when a record button is pressed, it becomes a record stop button, being put in the selected state. This further enhances the user friendliness.
