The BIFS is distinguished from the VRML in a view that the BIFS includes not only nodes defined at VRML but also nodes supporting video and audio defined in MPEG-4 standard, nodes for expressing 2-dimensional (2D) scenes and nodes for embodying MPEG-4 functions. Furthermore, an anchor node is included as a node describing a dual link.
[4] A terrestrial DMB interactive service provides a way of selecting and viewing data or documents related to predetermined contents by selecting link information included in the predetermined contents to a user. However, it is very difficult to display corresponding link information while watching a terrestrial DMB program in a terrestrial DMB terminal without distributing the displayed DMB program since a conventional terrestrial DMB terminal has a limited screen size. Such a difficulty seriously decreases satisfaction of a user.

Best Mode for Carrying Out the Invention
[23] Other objects and aspects of the invention will become apparent from the following description of the embodiments with reference to the accompanying drawings, which is set forth hereinafter.
[24] Fig. 1 is a block diagram illustrating an apparatus for storing link information of
DMB interactive contents and a DMB receiving terminal system using the same in accordance with a preferred embodiment of the present invention. Hereinafter, a method of storing link information according to the present invention will be also described with reference to Fig. 1.
[25] As shown in Fig. 1, a DMB receiving terminal system 100 for storing link information of DMB interactive contents includes a terrestrial DMB contents reproducing unit 110; a link information storing unit 120 for storing link information of DMB interactive contents; and a memory (storing unit) 130.
[26] The terrestrial DMB contents reproducing unit 110 receives DMB interactive contents transmitted through a broadcasting network and reproduces the received DMB interactive contents. The link information storing unit 120 extracts link information of DMB interactive contents while the DMB contents reproducing unit 110 is reproducing the DMB interactive contents, and independently stores the extracted link information.
[27] Hereinafter, the link informant storing unit 120 will be described in detail.
[28] The link information storing unit 120 stores link information included in DMB interactive contents, which are reproduced by the terrestrial DMB contents reproducing unit, in the memory 130. That is, the link information storing unit 120 stores the link information included in corresponding contents by creating additional files or directories while viewing terrestrial DMB broadcasting programs using the terrestrial DMB receiving terminal system 100 in order to use the stored link information without disturbing to view the DMB broadcasting program.
[29] As show in Fig. 1, the link information storing unit 120 includes a link information processing unit 121 and a memory processing unit 122.
[30] The link information processing unit 121 extracts link information of DMB interactive contents while the terrestrial DMB contents reproducing unit 110 reproducing the DMB interactive contents. In order to extract the link information, the link information processing unit 121 includes a user information processing unit 1211, an anchor node processing unit 1212 and a scene information processing unit 1213. The user information processing unit 1211 will be described with reference to Fig. 2, the anchor node processing unit 1212 will be described with reference to Fig. 3, and the scene information processing unit 1213 will be described with reference to Fig. 4 in detail.
[31] The link information processing unit 121 may extracts all of link information of the reproducing DMB interactive contents, or may extracts parts of link information selected by a user through a user interface.
[32] Meanwhile, the memory processing unit 122 stores the extracted link information in the memory 130. Herein, the memory processing unit 122 creates files or directories to store the extracted link information.
[33] Fig. 2 is a block diagram showing a user interface of link information in a user information processing unit shown in Fig. 1.
[34] The user information processing unit 1211 receives description information for link information of terrestrial DMB contents through the link information user interface 21. The description information received from the user includes a title/name of link information and a memo related to a link created by a user. The received description information can be extended.
[35] The memory processing unit 122 describes corresponding link information according to the inputted description information, and stores the described link information in the memory 130. For example, if a title of predetermined link information is inputted from a user, the input title is stored in the corresponding link information. Accordingly, the stored link information can be conveniently used later. [36] Fig. 3 shows a method of extracting link information in an anchor node processing unit shown in Fig. 1. That is, Fig. 3 shows operations performed by the anchor node processing unit 1212 in the link information processing unit 121.
[37] The anchor node processing unit 1212 extracts MPEG-4 scene description information 300 for each of link information in a scene description tree of terrestrial DMB contents which is being reproduced by the terrestrial DMB contents reproducing unit 110. That is, the anchor node processing unit 1212 extracts a uniform resource location (URL) 301, a description 302 and a parameter value 303 among anchor nodes for each of link information in the scene description tree of the DMB interactive contents.
[38] Fig. 4 shows a method of extracting link information in a scene information processing unit shown in Fig. 1. That is, Fig. 4 shows operations performed by the scene information processing unit 1213 of the link information processing unit 121.
[39] The scene information processing unit 1213 extracts MPEG-4 scene description information 400 for each of link information in a scene description tree of terrestrial DMB contents which is being reproduced by the terrestrial DMB contents reproducing unit 110. That is, the scene information processing unit 1213 extracts scene information included not only in anchor nodes but also in child nodes of corresponding anchor node from the scene description tree of the DMB interactive contents.
[40] The above described method according to the present invention can be embodied as a program and stored on a computer readable recording medium. The computer readable recording medium is any data storage device that can store data which can be thereafter read by the computer system. The computer readable recording medium includes a read-only memory (ROM), a random-access memory (RAM), a CD-ROM, a floppy disk, a hard disk and an optical magnetic disk.
