Abstract
A TV graphical user interface provided on a TV screen includes a graphical channel changer for enabling a user to select a required TV channel among about 1000 channels provided by a satellite TV system. The graphical channel changer contains a vertical channel bar composed of channel boxes that display numbers and logos of selected TV channels. To switch a TV set to a required TV channel, the user directs the pointing device at the graphical channel box that indicates the required channel. Up and down scroll bars, that allow the user to scan through the entire list of TV channels, dynamically alter their size in accordance with the position of the TV channel being currently scanned to provide the user with visual feedback. A relative position indicator is arranged between the up and down scroll bars.
