Abstract (en)
[origin: WO0145386A2] There is disclosed an emergency warning system for use in an appliance comprising a radio frequency (RF) receiver capable of receiving a broadcast radio signal or a broadcast television signal when the appliance is operating in a standby mode. The emergency warning system comprises a detector coupled to the RF receiver for detecting an emergency code in the received broadcast radio signal or broadcast television signal and generating a first signal. The emergency warning system also comprises a low power mode controller coupled to and receiving the first signal from the detector. The low power mode controller, in response to the first signal, switches the appliance from the standby mode to an active mode wherein the RF receiver processes and plays the received broadcast radio signal or a broadcast television signal.
