The terrestrial DMB contents transforming apparatus 10 transforms a terrestrial digital television (DTV) contents to a predetermined data format to transmit as a terrestrial DMB. For example, the predetermined data format is a format of storing contents employing the specifications of moving picture experts group - phase 4 (MPEG-4) Systems, such as extensible MPEG- 4 textual format (XMT) or MP4 file format. The terrestrial DMB contents editing and authoring apparatus 20 provides an interface, for example, a graphic user interface (GUI), to a user to edit and author the transformed format of terrestrial DMB interactive contents, such as XMT or MP file format terrestrial DMB interactive DMB contents, and edits and authors the terrestrial DMB interactive contents according to temporal/spatial arrangement and behavior events of objects based on the editing and authoring information of the user inputted through the GUI. The terrestrial DMB contents storing apparatus 30 stores the terrestrial DMB interactive contents. The
terrestrial DMB contents transmitting apparatus 40 transmits the stored terrestrial DMB contents to be suitable to a terrestrial DMB transmit format, for example, MPEG-2 transport stream (TS), according to a transmit schedule.
