The mobile communication terminal module provides various functions of the mobile communication terminal except for DMB. The DMB module receives and outputs DMB. The external broadcasting output unit outputs DMB received through the DMB module to an external Audio/Video (AV) device. The user interface unit provides operations of the mobile communication terminal mode and the DMB module for viewing continuity and receiving an input from the user. The controller designates the mobile communication terminal module for inputting an operating signal from and outputting the operating signal to the user interface unit if the controller senses a switching command signal for switching to the mobile communication terminal module through the user interface unit while DMB is output to the external AV device through the external broadcasting output unit.
