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).
