This cooperation is explicitly connected to COST 276.

36 36 Future directions: Improved multimedia information and data management methods, content and knowledge metadata descriptors, Agent architectures and technologies for agent communication and agent mobility, data delivery and retrieval, and for system management, Individualised service platforms based on user interface personalization, New algorithms, architectures and system design that provide special features required by personalised multimedia services, Advanced methods for Signal, Video, speech and sound processing and coding. The Action is oriented towards long-term basic research while recognising the iterative nature of developments in this field, due to the rapid development cycles of new technology. The major goal is to develop a vision of future application possibilities.

37 37 Conclusions The keyword: user-tailored information delivery in heterougeneous multimedia communication systems Promising 1 st year results Support for new communication technologies (p2p) will be integrated Interactivity among WGs and scientific cooperation between partners should be enhanced (financing) Financial Issues

38 38 Financial Issues Lack of financial fundings. high importance of COST projects vs. low fundings at least funds for eligible MC travel expenses and publications should be assured. Realised travel costs could not be reimbursed, 15 participating countries × 2 national delegates × 2 MCM á 1000 EUR = EUR publications of Workshops and of a book are pending short-term scientific missions are on hold as there are still open claims for travel and Workshop organisation.
