The on-screen displaying apparatus displays the remote control hand unit and its keypad graphically on the CRT 9 screen and changes the mode to help mode when the [MENU] key, for example, of the remote control hand unit 10 is pressed. In this help mode, when the user presses an arbitrary key on the remote control hand unit, the displayed key corresponding to the actually pressed key changes color or blinks on said CRT screen. At the same time, a functional description (the main points of the functional description described in the manual) of the key is displayed on said CRT screen. The user can use all the functions of any apparatus by using the remote control functions effectively even though he/she forgets the remote operational procedure or loses the manual.
