Definitions
- the present invention relates to an apparatus and method for storing link information of DMB interactive contents and a DMB receiving terminal system using the same, and more particular to an apparatus and method for extracting link information such as a URL of digital multimedia broadcasting (DMB) interactive contents received through a DMB network and additionally storing the extracted link information in order to overcome a limitation of a screen size of a DMB receiving terminal system and rapidly/easily access corresponding documents or data using the stored link information, and a DMB receiving terminal system using the same.
- DMB digital multimedia broadcasting
- MPEG-4 scene descriptions which configure terrestrial DMB interactive contents, are described as a binary format for scene (BIFS).
- the BIFS is developed based on a virtual reality modeling language (VRML). Scenes are expressed as a set of various nodes arranged in a tree structure, and the update of the scenes by a user s operation is achieved through a root as like as VRML.
- 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.
- 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.
- an apparatus for storing link information of DMB interactive contents including: a link information processing unit for extracting link information of digital multimedia broadcasting (DMB) interactive contents which is being produced in a DMB receiving terminal system; and a storing processing unit for storing the extracted link information in a storing medium.
- DMB digital multimedia broadcasting
- a method for storing link information of DMB interactive contents in a digital multimedia broadcasting (DMB) receiving terminal system includes the steps of: a) extracting link information of the DMB interactive contents by reproducing the DMB interactive contents; and b) storing the extracted link information in a storing medium.
- a digital multimedia broadcasting (DMB) receiving terminal system including: a DMB contents reproducing unit for receiving DMB interactive contents transmitted through a broadcasting network and reproducing the received DMB interactive contents; and a link information storing unit for extracting link information of DMB interactive contents which are being reproduced in the DMB contents reproducing unit.

- the memory processing unit 122 stores the extracted link information in the memory 130.
- the memory processing unit 122 creates files or directories to store the extracted link information.
- FIG. 2 is a block diagram showing a user interface of link information in a user information processing unit shown in Fig. 1.
- 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.
- 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.
- 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.
