Using a Global Positioning System for Transmitter Identification in Mobile Television
First Claim
1. Apparatus for use in a device, which is capable of being tuned to receive information, the apparatus comprising:
- a receiver for providing information for use in determining a location of the device; and
a processor for initiating re-tuning of the device as a function of distance between the location of the device and a location associated with a transmitter.

Abstract
A mobile digital TV (DTV) comprises a DTV receiver, a processor, a Global Positioning System (GPS) receiver and a memory for storing a data base of transmitter frequencies and transmitter locations for particular channels. The GPS receiver provides a location for the mobile DTV to the processor. The processor monitors distances between the location of the mobile DTV and at least two of the transmitter locations for a currently selected channel. Upon detecting that the mobile DTV is closer to a particular transmitting location than the other, the processor re-tunes the mobile DTV to the transmitter frequency of the closest transmitting for the currently selected channel.
