Abstract

A digital television (DTV) system includes a remote controller which generates X- and Y-axis position data; and an electronic pro gram guide (EPG) controller which receives position data responsive to the X- and Y-axis position data, which generates character data responsive to the position data, which searches EPG data for character strings approximating the character data to thereby generate search results, and which outputs the search results to the screen of the DTV. According to one aspect of the DTV system, the remote controller generates the X- and Y-axis position data responsive to movement of the remote controller. This movement can be determined by either accelerometers or a gyroscope included in the remote controller. According to another aspect of the invention, the X- and Y-axis position data can be generated by a pointing device, which can be either a touch panel or a trackball. A method for operating the DTV system responsive to changes in position data generated with respect to a remote controller is also described.
