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.

Abstract: A device and a method of updating a function in a digital broadcasting signal receiver. The device includes a storage section storing data for executing various functions provided to a digital broadcasting receiving section; a program specific information/service information (PSI/SI) extraction section extracting PSI/SI from a received digital broadcasting signal; and a function realization section identifying a supported function from the digital broadcasting signal according to the PSI/SI and searching the data for executing the identified function from the storage section so that the identified function can be executed in the digital broadcasting receiving section.

Abstract: A digital broadcasting system having a digital TV including a broadcasting base station which transmits a broadcasting signal having a program and key combination information configured to control a function by the program; and the digital TV includes a user inputting part having a plurality of keys; a receiving part which receives the broadcasting signal; a detecting part which detects the program and the key combination information provided through the broadcasting signal; a storing part which stores the program and the key combination information outputted by the detecting part; and a controller which performs a function of the combination of the inputted keys on the basis of the key combination information.

Abstract: Methods and apparatuses for downloading software from a digital broadcasting system to a broadcasting signal receiving device are provided. A broadcasting signal is transmitted by a broadcasting base station that includes software update data and medium information to access another provision medium that provides the software update data. The broadcasting signal is received by the broadcasting signal receiving device and updateable software and the medium information are extracted if the updateable software exists in the broadcasting signal. The extracted medium information is stored and a download of the extracted software is started. The download of the extracted software is monitored and re-downloading the software may be performed if the download is abnormal. Thus, downloading of the software may be performed through other reception paths if an operation of downloading the software through a broadcasting signal is not normally performed.
