Design and Integration of JMF-Based Multimedia-Supported Environment in a Product Data Management System

In order to meet discipline experts' requirements of knowledge exchange, conflict resolution, and design decision in the collaborative product design process, a JMF-based multimedia-supported environment (MSE) is proposed. The requirement to develop the MSE for multi-disciplinary collaborative design process is analyzed. Related key technologies of multimedia applications required to build the integrated MSE are described. Construction of multimedia interaction mode, design of system architecture, and formulation of development plan are implemented. Discipline experts' roles are defined, and safety certification function of application programs is achieved. Based on the development platform of Java 2 enterprise edition (J2EE), the realization of the system is completed, and the system is integrated into a previously developed product data management system. Through system experiment and test, the JMF-based system environment can well meet the needs of multimedia real-time interaction, knowledge sharing, and collaborative decision making in the process of collaborative product design.
