UMA Media base � Metadata Management using Oracle Database System

This paper describes the media base in a Universal Multimedia Access (UMA) test bed for handling multimedia presentations in an MPEG-21 environment. The media base introduces an effective way of storing, query organizing, exchanging important metadata and key Digital Items on the server side of a UMA enabled system. The functionality of the media base is demonstrated through an implemented application for streaming of adapted MPEG- 4 media resources over the MPEG-21 multimedia framework.
