Abstract [en]

The dynamic adaptation of multimedia content in distributed heterogeneous environments is a key enabler for next generation ubiquitous and pervasive services. Systems implementing the Universal Multimedia Access (UMA) approaches are predominantly combinations of MPEG-centric and/or proprie-tary solutions. However, it is important to reach interoperability between the IETF approach for multimedia-session establish-ment and control and the MPEG-21 efforts for metadata-driven adaptation, in order to enable personalized multimedia delivery for ubiquitous users, where media is delivered and adapted on the fly taking into account context and environment. In this pa-per, we present a format-independent model that enables con-verging IETF and MPEG-21 descriptions for streaming media. We introduce the architecture of a multimedia stream-adaptation service to enable communication between terminals having het-erogeneous capabilities and communicating over heterogeneous networks. We demonstrate how the service utilizes the converged session description model and how it can be deployed inside special adaptation nodes within any part of the network to enable dynamic content adaptation both at the terminal and within the network
