THE BROADCASTING SIGNAL FOR REALIZING EMERGENCY ALERT SYSTEM IN A TERRESTRIAL BROADCASTING, THE METHOD OF CONTROLLING THE BROADCASTING SIGNAL, AND THE RECEIVER FOR RECEIVING THE BROADCASTING SIGNAL

摘要

A broadcasting signal related to an emergency alarm of a terrestrial broadcasting and a method and a broadcasting receiver for processing the same are provided to remove the forecasted channel duplication problem and unnecessary processes of a relay station. A process for receiving an EAT(Emergency Alert Table) including information for discerning a competent relay businessman of one or more areas and physical channel number information of a terrestrial broadcasting station mapped into the discerning information is performed(S701). Thereafter, a process for reading out the physical channel number of the terrestrial broadcasting station corresponding to the area of a specific competent relay businessman by parsing the received EAT is performed(S702). Thereafter, when generating an emergency situation, a process for tuning toward the physical channel number of the terrestrial broadcasting station is performed(S703).
