<p>An alert receiver (26) includes a discriminator, which receives encoded signals from a network. The encoded signals report an event from an information source coupled to the network, wherein the discriminator (32) compares the encoded signals, which include codes designating geographic locations, to codes associated with specific localities to determine whether to alert a user. A warning device (30) is responsive to a result of comparing the encoded signals to the codes associated with specific localities.</p> |
