Abstract: A digital broadcasting system and a method for processing data in the same are disclosed. A method for controlling a digital television (DTV) located in one independent space among a plurality of independent spaces physically separated from one another is disclosed. The DTV includes an access point (AP) card. The method includes receiving emergency alert information and independent space identification (ID) information from a management server, comparing independent space ID information pre-stored in the DTV with the received independent space ID information, parsing the emergency alert information when the pre-stored independent space ID information is identical to the received independent space ID information, and switching an operation mode of the DTV from a power-off mode to a wake mode on the basis of the parsed emergency alert information, and displaying the emergency alert message.
