First Claim
1. Method for decoding a menu data segment read from a removable storage medium, the method comprising the steps of detecting within the menu data segment data corresponding to a plurality of menu buttons;
- extracting from the menu data segment for each button of the plurality of menu buttons at least first data defining whether the button is selectable and second data defining whether the button has graphic representation data associated;
decoding data corresponding to first menu buttons to selectable display data, wherein the first buttons have graphic representation data associated and are selectable;
decoding data corresponding to second menu buttons to non-selectable display data, wherein the second menu buttons have graphic representation data associated and are not selectable; and
decoding data corresponding to third menu buttons to selectable and invisible menu elements, wherein the third menu buttons have no associated graphic representation data stored within said menu data segment, and wherein the third menu buttons are automatically activated upon selection.

Abstract
Optical storage media often contain data structures for a menu suitable for selection of a title, a chapter, a parameter or others. Such menus usually comprise a number of buttons to be displayed, with each button having a state. Possible states of buttons are e.g. “unselected”, “selected” or “activated”. According to the invention, the menu may contain buttons that can be selected through the keys on the remote control, but that don'"'"'t have any images or text associated. This allows creating “invisible buttons” that automatically execute commands upon selection. Further, a 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. Such menu data may be stored e.g. on a Blu-ray disc.
