6 information system architecture

From a system development perspective, a multimedia information system may be considered as a multimedia database, providing storage and retrieval facilities for media objects. Yet, rather than a solution this presents us with a problem, since there are many options to provide such storage facilities and equally many to support retrieval.

In this chapter, we will study the architectural issues involved in developing multimedia information systems, and we will introduce the notion of media abstraction to provide for a uniform approach to arbitrary media objects.

Finally, we will discuss the additional problems that networked multimedia confront us with.
