MPEG-7 Contents based Indexing on Mobile Internet   In our research, main purpose is the technology research and development of MPEG-7 system for contents based retrieval system and the QoS guarantee of multimedia data delivery through Mobile Internet. For the purpose, we need QoS guarantee technique in Mobile Network, contents based retrieval System using MPEG-7 System and effective delivery method of searched result. In details, research goal contains flexibility of resource reservation path in QoS guarantee, and dynamic optimization method of extended reservation path, movement prediction and excess reservation method, and effective wireless network system. MPEG-7 contents based retrieval system contains development of contents based indexing algorithm, MPEG-7 System with user interface, delivery of multimedia data in mobile Internet. Finally, combining these two field of study, users of mobile Internet can search of multimedia data and get Multimedia data in QoS guaranteed Internet. We can secure leading core technique by developing union system.   Fig. 1. Overview of MPEG-7 Contents based Indexing on Mobile Internet   As shown Fig. 1, our mobile MPEG-7 system is composed of server-client manner. The contents, like videos and images, is featured by MPEG-7 descriptor. The contents and their features are delivered to client over mobile protocol, like RSVP.
