Abstract
A digital television is presented that stores multiple channel maps in its channel memory. Each map is associated with a particular geographic location. When the television moves to a new location, the location is identified and the television examines its memory for stored channel maps relevant to that location. If a relevant channel map is found, it is used without the television having to rescan the available television frequencies to create a new map for that location. When scans are required, they are expedited by examining a database of relevant frequencies for the television's location. The database identifies frequencies that are in use by television broadcasters near that location. The television then needs to scan only those frequencies identified in the received list, which reduces scan times.
