<p><P>PROBLEM TO BE SOLVED: To easily set a channel even when space area is present on a display screen. <P>SOLUTION: When shifting the present display position of a display button, whether or not an adjacent display button position present in the shifting direction of a display position is the space area of the display button is determined, and when the display button position is the space area, the present display position is skipped to the area of the displayed first display button. The display button area after skipping is turned to the present display position and change to a display state indicating the present position is performed. Thus, even when the button display area is the space area, the space area is automatically skipped and the display position is shifted to the position of the actually displayed display button. Channel display is easily set (stopped and skipped) and it is convenient especially when the number of display channels is large. Since a channel skipping processing is a recursive processing, even when the space area is successively present, the determining processing routine is simplified. <P>COPYRIGHT: (C)2003,JPO</p> |
