Abstract
Abstract A remote control device has the function of receiving FM multiplex broadcasting, storing the television program data transmitted from a broadcasting station into a television program memory, and displaying the stored program data. In the television program memory, the broadcasting dates, channels, broadcasting start and end times, program names, and G codes are stored. When the user chooses the program the user wants to record from the displayed programs, the remote control code for reserving the selected program for recording will be transmitted to the videotape recorder, thereby making a reservation for recording.
