An apparatus and method for displaying a digital multimedia broadcasting (DMB) service, which is capable of always displaying a dynamic label service (DLS) of a digital audio broadcasting (DAB) signal in a ticker form in a digital multimedia broadcasting receiver. A method of displaying a digital multimedia broadcasting service includes determining whether additional data carried in a digital audio broadcasting (DAB) signal is received while any application is being executed; and displaying the executed application and the received additional data together on one screen when the additional data is received. Accordingly, since news information or traffic information can be always received in the DMB receiver even during the execution of any application, it is possible to make the DMB receiver more convenient for a user.
