As illustrated in FIG. 8A, an event that requires displaying an object may occur while a predetermined screen is displayed on the display 170 of the image display apparatus 100. When an event occurs, the controller 180 of the image display apparatus 100 determines the type of the last used remote controller by referring to the information stored in the storage 160.

In the present embodiment, the last remote control device used by the user of the image display apparatus 100 before the event occurs is a general remote control. When an event occurs, the controller 180 displays 301 OSD and 302 OSD on the display 170 of the image display apparatus 100 as shown in FIG. 8B.

The user may change and use a type of remote control apparatus capable of inputting a command to the image display apparatus 100. In this embodiment, the user uses the general remote control before the event occurs and then uses the spatial remote control after the event occurs. The user may operate the OK button of the spatial remote controller while the Yes icon is highlighted in the 302 OSD of FIG. 8B. In this case, the video display device 100 tunes in to the reserved-viewed channel in response to a user command.

As illustrated in FIG. 8C, the controller 180 of the image display apparatus 100 may display a 305 OSD on the display 170 informing the user that the channel is being switched during the channel switching time. In addition, the controller 180 recognizes that the Yes icon of FIG. 8B has been operated in response to a command received through the spatial remote controller. That is, the controller 180 recognizes that the type of the remote control apparatus stored in the storage 160 and the type of the remote control apparatus currently used by the user are changed.

Therefore, the controller 180 displays the pointer 306 corresponding to the spatial remote controller used by the user on the display 170 together with the 305 OSD. The user can use the spatial remote control instead of the general remote control after the event occurs.
