A digital broadcasting apparatus comprising: a storage unit which stores one of a picture in picture (PIP) mode and an application mode running a downloaded application program as a designated target mode; an embodiment unit which provides a PIP function corresponding to the PIP mode and an application function corresponding to the application mode; and a control unit which determines whether the PIP mode is currently activated, determines the target mode stored in the storage unit if it is determined that the PIP mode is currently activated, and controls the embodiment unit to provide at least one function of the application function and the PIP function based on the determined target mode, wherein the control unit runs the application program; wherein if the application program requests a current state of the PIP mode through a first application program interface (API), the control unit checks the current state of the PIP mode to respond to the application program, and wherein if the application program requests a determination of a currently set target mode through a second API, the control unit determines the target mode stored in the storage unit to respond to the application program.
