Distributed multimedia information presenting environment

Many multimedia systems are focusing on the techniques of teleconferencing applications and discussing the general reference architectures. Generally speaking, a distributed multimedia application is constructed of four layers: the interactive layer, the data composition layer, the network transport layer and the database management system (DBMS) layer. Although these layers are the well-known reference architectures, the connections (multimedia modeling, module operations, and module communications) between them still need to be solved. To allow users easily, flexibly, and dynamically to create, query, and present multimedia documents, the authors propose five modules as an integration solution; they are, interactive user interface module, multimedia object manipulation module, object dynamically mapping module, network transport control module, and physical object file manipulation module. These modules are the essences of the behaviorally object-oriented distributed multimedia environment. Based on these modules, the multimedia object modeling, the query processing and the presentation schema are elaborated.<>
