PURPOSE: A user interface device of a digital TV is provided to make a user directly confirm and search a file system by a data service of the digital TV, thereby performing a desirous application or downloading data. CONSTITUTION: An OC(Object Carousel)(60) searches a BIOP(Broadcast Inter-ORB Protocol) message in section data of a data stream, and configures a BIOP object. Performers perform an operation of an MHEG(Multimedia and Hypermedia information coding Expert Group) by using the BIOP object. A tree structure manager(140) manages information to be displayed in a UI(User Interface), based on binding list information, and stores file names and file types as tree types, then has a pointer for upper/lower lists. A UI tree view manager(150) displays a file structure in the UI, and transmits a user's input to the tree structure manager. An application selector(170) receives a selected file and an application, to configure every position of the file, and analyzes a type of the selected file to transmit an analyzed application to the UI. A launcher(120) receives the file positions, and activates at least one of the performers. |
