<p>A TV graphical user interface 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 the TV set to a required TV channel, the user directs the pointing device at the graphical channel box that indicates the required channel. A direct access channel bar is arranged on a screen so as to cause the channel boxes to display the number and logo of a selected TV channel when the user directs the pointing device at the point on the direct access bar that represents the selected channel. The direct access channel bar is provided with an absolute cursor position indicator that indicates to the user the numbers of TV channels represented by various points on the direct access channel bar, when the user moves the pointing device over these points. When TV channels in the channel changer are arranged in alphabetical order of channel or program names, the absolute cursor position indicator indicates the first letter in the name of a TV channel or program represented by a point on the direct access bar, at which the pointing device is directed.</p> |
