Disclosed is a method for providing heterogeneous services using a PIP function in a terrestrial DMB receiver. The method includes: a first step of receiving a key input for activating the PIP function and displaying a list of services in an available ensemble during use of a desired DMB service; a second step of selecting a desired item in the list of services; a third step of identifying if the desired item selected at the second step is an "exchange" function and identifying if PIP function of the terrestrial DMB receiver is activated when the selected item is the "exchange" function; a fourth step of exchanging a service of a main screen for a service of a PIP screen, when it is identified that the PIP function is activated at the third step; and a fifth step of identifying if the desired item selected at the second step is the "exchange" function and displaying the selected item on the PIP screen when the selected item is not the "exchange" function.
