Abstract:
An apparatus such as a television signal receiver, radio or other device provides an emergency alert function. According to an exemplary embodiment, the apparatus includes a tuner for tuning a plurality of frequency channels associated with the emergency alert function. A processor identifies one of the frequency channels having higher signal strength relative to the other frequency channels, and enables use of the identified frequency channel for receiving emergency alert signals.
