The method of managing the application related to data broadcasting, the class/interface structure for controlling the same, and the receiver for controlling the same

A method for limiting a data broadcasting association application, a class and interface structure, and a broadcasting receiver therefor are provided to solve a problem in which a native application conflicts with the data broadcasting association application. A CPU judges whether an input mode of a broadcasting receiver is a data broadcasting mode(S306). When the input mode of the broadcasting receiver is not the data broadcasting mode, the CPU stops the execution of a data broadcasting association application(S307). The CPU operates the broadcasting receiver according to a native application which previously exists(S308).
