Abstract
Systems and methods are disclosed for communicating an emergency alert message from a digital radio broadcast transmission system of a mobile vehicle to a digital radio broadcast receiver system. A digital radio broadcast signal including first and second data is broadcasted using the digital radio broadcast transmission system to end-user digital radio broadcast receivers. The first data includes an emergency code, and the second data includes an emergency alert message. The digital radio broadcast signal is transmitted at a predetermined frequency that is recognized by the receivers as an emergency notification frequency. The digital radio broadcast signal can be decoded only by receivers located within a localized area in a proximity of the transmission system. The receivers are configured to automatically tune to the emergency notification frequency to receive the digital radio broadcast signal and render the second data based on a detection of the emergency code within the signal.
