<P>PROBLEM TO BE SOLVED: To provide a method for displaying a menu suitable for selection of a title, chapter, parameter or the like, included in an optical storage medium. <P>SOLUTION: Menus usually comprise a number of buttons (BO) to be displayed, with each button having a state. Possible states of buttons are e.g. "unselected", "selected" or "activated". The menu may contain buttons (INV1-INV4) that can be selected through keys on a remote control, but that do not have any images or text associated. This allows creating "invisible buttons" that automatically execute commands upon selection. Further, sound or sound sequence, e.g. melody or click, may be associated to a buttons state, and may be played back when the button enters this state. <P>COPYRIGHT: (C)2013,JPO&INPIT |
