Abstract
A portable digital television (DTV) comprises a processor, a channel and volume changing button arrangement, and a navigational button arrangement. Either or both button arrangements can be used in at least a bi-modal operation. In a first mode of operation, the button arrangements provide their normal functions, and in the second mode of operation, the button arrangements provide an interactive application interface to the user. Preferably, one of the two button arrangements is selected for the bi-modal operation. The selected button arrangement is associated with at least an optical element for lighting the button arrangement. The controller operates the optical element such that the selected button arrangement has one color in one mode of operation and has a different color in the other mode of operation.
