Method of selection of a button in a graphical bar, and receiver implementing the method

摘要

The present invention relates to a method of navigation around documents represented by identifiers displayed on a viewing screen. Navigation commands control the position of a cursor also displayed on the screen, independently of the position of the identifiers. The identifiers automatically scroll over the screen as a function of the position of the cursor on the screen thus defining the direction of scrolling. When the cursor is positioned on an identifier, the latter is highlighted and the user can enter a command to activate the document, for example to reproduce it. Advantageously, the identifiers scroll over concentric carrousels, each carrousel containing identifiers of documents having common properties. The invention also relates to a viewing appliance able to execute a navigation software module.

1. A method of navigation around documents represented by identifiers appearing in a menu displayed on a viewing screen, comprising:
dividing the documents into a plurality of groups, each group being represented by one of a plurality of scrolling concentric carrousels containing the identifiers of the documents belonging to this group; displaying a cursor on the screen; controlling the position of said cursor by navigation commands, independently of the position of the identifiers of the documents; scrolling together the plurality of carrousels over the screen as a function of the position of the cursor in the menu displayed on the screen defining the direction of scrolling and the speed of scrolling, the angular speeds of the plurality of carrousels being different, the difference between the angular speeds of two carrousels being constant; and positioning the cursor on one of the identifiers to trigger highlighting of the identifier and to authorize activation of the document associated with this respective identifier by an entry of a command.
