A digital television receiver includes a tuner receiving a digital television signal including a DCCT, a demodulator demodulating the digital television signal, and a demultiplexer demultiplexing the DCCT from the demodulated signal. The receiver further includes a decoder parsing channel ID information and a priority code from the DCCT, where the channel ID information specifies an emergency alert channel associated with an emergency alert event and the priority code specifies an alert priority of the emergency alert event. The receiver further includes a controller that controls operation of the tuner to automatically tune to the emergency alert channel based upon the alert priority.
