On a display unit, icons representing types of video signals supplied to respective ones of a plurality of input terminals are displayed. When a user operates a remote and selects an icon representing the type of desired video signal, a video image derived from the video signal of the desired type supplied to the input terminal that corresponds to the selected icon is displayed on the display unit. In such a situation, arrangement of icons on the display unit can be changed by a user instruction given by an operation of the remote. Further, the icons also show shapes of the input terminals, and therefore, the user can easily confirm to which input terminal of which shape the device supplying the video signal of the type indicated by the icon is to be connected.
