Universal and Personalized Access to Content via J2ME Terminals in the DYMAS System

Abstract

This paper presents the content adaptation application for mobile terminal within the current status of the Deferred Time Environment (DTE) of the DYMAS system. The DTE enables universal and personalized access to multimedia content over fixed and mobile networks. After introducing the system architecture, we show the differences between the functionalities for fixed and mobile networks, and detail the development of the application targeted to J2ME terminals. The system uses MPEG-21 for the description of sessions (terminal and network capabilities and user preferences) and MPEG-7 for content descriptions, which are the base for the Annotation, Search and Browsing, and Transcoding appliances. © Springer-Verlag 2004.
