@article {3053, title = {An Architecture for Interactive Distributed Multimedia Information Services}, journal = {Telecommunication Information Management Journal, Volume 2, Issue 4}, year = {2002}, pages = { 3 - 10}, abstract = {In this work, we present an architecture for interactive distributed multimedia information services. The service consists of three basic parts, the clients, the access servers, and the content servers. Clients manage the presentation of the requested multimedia documents, while also ensure the synchronization among various involved media. Special policies for the synchronized presentation of multimedia documents and user interactions management are discussed. Access servers authorize the users for legitimate use of the service, while also provide various searching capabilities Content servers manage the transportation of multimedia documents over a broadband network and the user interactions. The proposed architecture preserves scalability, flexibility and modularity due to the distributed nature of the architecture, while also results in good performance due to the dynamic allocation of resources.}, author = {Christos Bouras and Vaggelis Kapoulas and Paul Spirakis and D Moiras and V Ouzounis} }
