Abstract

A method is presented for providing information associated with a geographical area to users of broadcast communication receivers. The information, as well as an indication of the geographical area associated with the information, are transmitted to, and received by, each of the broadcast communication receivers. In each of the receivers, the indication of the geographical area is compared with a geographic code associated with, and stored within, the receiver. Each of the receivers also provides at least one alert to a user of the respective broadcast communication receiver if the geographic area is located on a travel vector of the respective broadcast communication receiver indicated by the geographical code.

Claims

1. A broadcast communication system, comprising:

a plurality of broadcast receivers; and

a broadcast communication transmitter configured to;

receive information and an indication of a geographical area associated with the information;

translate the indication of the geographical area from a first geographical format into a second geographical format such that the indication of the geographical area can be compared with a geographical code associated with, and stored within, each of the plurality of broadcast receivers; and

transmit the information and the translated indication of the geographical area to the plurality of broadcast communication receivers;

wherein each of the plurality of broadcast receivers are configured to;

receive the information and the translated indication of the geographic area from the broadcast communication transmitter;

compare the translated indication of the geographical area with the geographic code stored within the respective broadcast communication receiver; and

provide at least one alert to a user of the respective broadcast communication receiver if the geographic area is located on a travel vector of the respective broadcast communication receiver indicated by the geographical code stored within the respective broadcast communication receiver.

2. The system of claim 1, wherein the respective broadcast communication receiver converts from a standby mode to a fully operational mode when the respective broadcast communication receiver determines that the geographic area is located on the travel vector of the respective broadcast communication receiver indicated by the geographical code in order to provide the at least one alert.

3. The system of claim 1, wherein the information relates to at least one navigational message.

4. The system of claim 3, wherein the at least one navigational message relates to at least one automobile accident, road closure, or road condition.

5. The system of claim 1, wherein the geographical code indicates that the broadcast communication receiver is not currently located within the geographical area.

6. The system of claim 1, wherein the plurality of broadcast receivers comprise a plurality of navigational devices.
