This paper presents a system providing functionalities for cataloging multimedia content using MPEG-7 and accessing to content and descriptions. The cataloging application indexes content using MPEG-7 and creates annotated variations in order to have the capability of offering media content to a large amount of different terminals and through different access networks. The created multimedia database, both descriptions and content (original sources and variations), is used by, currently, two applications: a searching application, which allows a user selecting specific tags to find the desired media; and a filtering application for transparent access to the content database using profiles. These profiles can be selected from a profiles database or created by the user specifying content preferences, and network and terminal parameters.
