PROBLEM TO BE SOLVED: To release a view-limitation function with an easy operation by allocating two kinds of remote control codes to each function about selection of a received video to control, releasing the view-limiting function with respect to one kind of the remote control codes received by a remote control signal receiving device and enabling normal viewing with respect to an arbitrary video. SOLUTION: A remote control light receiving device 21 receives a remote control signal of two kinds of remote control codes, converts it into a remote control signal b1, and supplies it to a microcomputer 22. The microcomputer 22 samples the signal b1, allocates two kinds of the remote control codes to each function regarding the selection of a received video to control, also releases a view-limiting function with respect to one kind of the remote control codes received by the device 21, enables normal viewing with respect to an arbitrary video, operates the view limitation function about a remote control code except it and disables normal viewing with respect to a specific video. |
