Abstract
Methods and systems for seamlessly broadcasting data to a user moving among a plurality of broadcast coverage areas. A first signal containing desired data may be received by a receiving device at a user location, wherein the first signal is broadcast from a first transmitting station associated with a first broadcast coverage. Thereafter, the receiving device (e.g., a radio or in-vehicle television) can be automatically instructed to search for and tune to a second transmitting station associated with a second broadcast coverage area broadcasting a second signal containing the desired data if the first signal fades at the user location, thereby permitting the user to seamlessly receive data as the user moves among a plurality of broadcast coverage areas. The receiving device can also be automatically instructed to search for and tune to a third transmitting station broadcasting a third signal containing data of a type associated with the desired data, if the second signal containing the desired program cannot be identified.
