Device for updating component of application software in digital broadcasting signal receiver and method thereof

Abstract

A device for updating component of application software in a digital broadcasting signal receiver and a method thereof. A storage section stores executing data for executing application software that produces a user interface of the digital signal receiver. A program specific information/service information extracting section extracts program specific information/service information (PSI/SI) from a received digital broadcasting signal. An updating data extracting section extracts updating information for partially updating the application software from the program specific information/service information, and extracts updating data for updating the application software from the digital broadcasting signal according to the updating information in order to update the executing data stored in the storage section to the extracted updating data. An application software section updates and executes the application software according the updated executing data. Therefore, time and resources required to update application software are saved.
