摘要：<p>A television signal processing system (20) having an emergency alert function is capable of receiving emergency alert signals and providing alert outputs to notify individuals of emergency events. According to one exemplary embodiment, the television signal processing system (20) includes a tuner (22, 42) operative to tune a frequency including emergency alert signals indicating an emergency event. A processor (26, 53) is operative to enable an alert output responsive to the emergency alert signals when the emergency event indicated by the emergency alert signals corresponds to a geographical area selectable by a user. According to another exemplary embodiment, the processor (26, 53) is operative to enable an alert output responsive to the emergency alert signals when the emergency event indicated by the emergency alert signals corresponds to a predetermined event selectable by a user.</p>
