the korrontea data modeling
Needs of multimedia systems evolved due to the evolution of their architecture which is now distributed into heterogeneous contexts like the Internet network. A critical issue lies in the fact that they handle, process, and transmit multimedia data. This data integrates several properties which should be considered since it holds a considerable part of its semantic, e.g. the lips synchronization in a video. In this paper, we focus on the definition of a basic abstraction for describing and modeling data in multimedia systems by taking into account their properties. This abstraction is proposed with synchronization policies to ensure synchronous transport of multimedia data. We use it in a component model that we develop for the design and deployment of distributed multimedia systems.
