Additional information contained in a broadcast signal is classified by type before transmission. Only additional information of the type(s) desired by a user is selected and acquired from the received additional information. The type(s) of additional information acquired is (are) displayed on a screen in real time. Accordingly, only the additional information needed by the user is selectively stored in memory and memory can be efficiently used. Since the type(s) of additional information received is (are) displayed on the screen in detail, the user can easily understand the type(s) of additional information being received currently so that the additional information can be effectively used. In addition, subdivided additional information suitable for the various classes of TV viewers can be developed so that additional information contents can be efficiently developed.
