The standard supports applications to exchange, identify and filter multimedia contents based on MPEG-7 descriptions. However, especially mobile applications that deal with MPEG-7 suffer from limited bandwidth, low computational power and limited battery life. In this document we describe an index system that allows filter mechanisms and random access to encoded MPEG-7 streams and which overcome the limitation of the network and the consuming terminal. Encoding is applied in order to reduce the data rate of the XML documents to be transmitted. The indexed parts of the encoded streams can be accessed without the need to deserialize the complete stream. Furthermore, the system is evaluated and results of the experimental evaluation are discussed.}, address = {NA}, language = {EN}, publisher = {NA}, url = {http://www.hindawi.com/GetArticle.aspx?doi=10.1155/ASP/2006/15482} }
