Abstract

An apparatus such as a television signal receiver includes an emergency alert function which, when activated, provides an alert output to notify users of an emergency event. According to an exemplary embodiment, the apparatus includes a tuner operative to tune signals including emergency alert signals capable of activating the emergency alert function. A processor is operative to detect a condition indicating relocation of the apparatus after a power interruption to the apparatus, and to enable a predetermined output associated with the emergency alert function responsive to detecting the condition.

Claims (25)

1. A method for controlling an apparatus having an emergency alert function, comprising:

detecting a power interruption to said apparatus;

determining an estimate of the duration of said detected power interruption;

comparing said estimate of the duration of said detected power interruption to a predetermined threshold; and

responsive to a determination that said estimate of the duration of said detected power interruption exceeded said predetermined threshold, enabling a user to provide updated information comprising location information associated with the emergency alert function responsive to detecting said power interruption.

2. The method of claim 1 , wherein said updated information comprising location information includes a FIPS location code.

3. The method of claim 1 , wherein said updated information includes a type of emergency event.

4. An apparatus having an emergency alert function, comprising:

tuning means for tuning signals including emergency alert signals capable of activating said emergency alert function; and

processing means for:

detecting a power interruption to said apparatus;

determining an estimate of the duration of said detected power interruption;

comparing said estimate of the duration of said detected power interruption to a predetermined threshold; and

responsive to a determination that said estimate of the duration of said detected power interruption exceeded said predetermined threshold, enabling a user to provide updated information comprising location information associated with the emergency alert function responsive to detecting said power interruption.

5. The apparatus of claim 4 , wherein said updated information comprising location information includes a FIPS location code.

6. The apparatus of claim 4 , wherein said updated information includes a type of emergency event.

7. A television signal receiver having an emergency alert function, comprising:

a tuner operative to tune signals including emergency alert signals capable of activating said emergency alert function; and

a processor operative to:

detect a power interruption to said television signal receiver;

determine an estimate of the duration of said detected power interruption;

compare said estimate of the duration of said detected power interruption to a predetermined threshold; and

enable a user to provide updated information comprising location information associated with the emergency alert function responsive to detecting said power interruption responsive to a determination that said estimate of the duration of said detected power interruption exceeded said predetermined threshold.

8. The television signal receiver of claim 7 , wherein said updated information comprising location information includes a FIPS location code.

9. The television signal receiver of claim 7 , wherein said updated information includes a type of emergency event.
