Apparatus for Coding Metadata based on eXtensible Markup LanguageXML

摘要

PURPOSE: An XML(eXtensible Markup Language) based meta data encoding apparatus and a method thereof are provided to apply separation and transmission of AU(Access Unit) by supplying a visual edit tool for updating meta data. CONSTITUTION: A meta data production device produces meta data relating to multimedia contents. A meta data encoding device(120) encodes the produced meta data so that the produce meta data may be changed as a transmission format. Encoded meta data can be transmitted to an interactive terminal via a transmission network. A meta data input unit(210) receives previously manufactured meta data and skima. A meta data parsing unit(220) produces an initial decoding information through a skima analysis related to the inputted meta data. A meta data structure representation unit(230) changes the meta data received from the meta data input unit(210) into a tree structure type and displays the structure to a user. A meta data AU editing unit(240) performs an editing for manipulating meta data.
