Abstract

An apparatus such as a television signal receiver (20) provides an emergency alert function. According to an exemplary embodiment, the television signal receiver includes a first tuner (23) for tuning a first channel when the television signal receiver is in an on mode. A second tuner (25) is provided for tuning a second channel when the television signal receiver is in the on mode and an off / standby mode. The second channel provides emergency alert signals capable of activating the emergency alert function.

Description

technical field [0001] The present invention relates generally to a device capable of providing emergency alert signal functionality, such as a television signal receiver and / or modem, and more particularly to a technique for using such a device to receive an emergency alert signal. Background technique [0002] Emergencies such as severe weather, natural disasters, fires, civil emergencies, acts of war, toxic chemical releases, radiation releases, or other similar situations can be devastating to unprepared individuals. Typically, for weather-related emergencies, authorities such as the National Weather Service (NWS) and the National Oceanic and Atmospheric Administration (NOAA) are able to detect severe weather before the general public. Through the use of modern weather detection equipment, such as Doppler radar and weather satellites, the NWS and NOAA are able to issue early warnings of severe weather conditions, which has saved many lives. However, for such an alert to...
