Abstract
An HDTV receiver coupled to a terrestrial antenna displays real-time signal strength of terrestrial digital television signals. A graphical user interface preferably displays various data relating to all terrestrial television signals in a scrollable grid format. The grid is displayed within an active video display of a selected television signal from the grid. Audio for the selected channel is also active. A list of all channels tuned or selected is maintained to aid in searching. Channel lists are updated during certain channel searches.
