Abstract

A system and method for broadcast reception management. In some embodiments, a database is used to determine the available broadcasts and associated channel numbers for a given location. In other embodiments, a station list is determined for a specified broadcast, the station list comprising a first channel of a first station on which the specified broadcast is broadcast at a first location and a second channel of a second station on which the specified broadcast is broadcast at a second location. The communication circuitry of the wireless electronic device is tuned in accordance with the station list to the first channel in the first location to receive the specified broadcast. The communication circuitry is retuned to the second channel in the second location to continue reception of the specified broadcast.
