Paper Abstract

Development towards high-bandwidth wireless devices that are capable of processing complex, streaming multimedia is enabling a new breed of network-based media services. Coping with the diversity of network and device capabilities requires services to be flexible and able to adapt to the needs and limitations of the environment at hand. Before efficient deployment, multi-platform services require additional issues to be considered, e.g. content handling, digital rights management, adaptability of content, user profiling, provisioning, and the available access methods. The key issue is how the content and the service is being modelled and stored for inauguration. We propose a new service content model based on persistent media objects able to store and manage XHTML-based multimedia services. In our approach, media, content summaries, and other meta-information are stored within media objects that can be queried from the object database. The content of the media objects can also specify queries to the database and links to other media objects. The final presentation is created dynamically according to the service request and user profiles. Our approach allows for dynamic updating of the service database together with user group management, and provides a method for notifying the registered users by different smart messaging methods, e.g. via e-mail or a SMS message. The model is demonstrated with an 'ice-hockey service' running in our platform called Princess. The service also utilizes SMIL and key frame techniques for the video representation.
