Abstract
Provided is a method for processing updated data of an application in a headend or a subscriber's terminal of a digital data broadcasting system. The method of the present research forms updated object modules and non-updated object modules among the objects of the application data, transmits them to a subscriber's terminal, abstracts the updated objects in the subscriber's terminal among the objects transmitted from the headend, and outputs them onto a screen, when the objects of the application data are updated in the headend. The updated data processing method includes the steps of: a) confirming that the application data are updated upon an application content update request of a subscriber terminal or application file update of a contents provider; b) generating signaling information of the updated application data and transmitting the signaling information; c) separating updated objects from non-updated objects among objects constituting the application, and updating a file system structure and contents of the application; and d) forming modules including the updated objects and modules including the non-updated objects, updating version information of the modules including the updated objects.
