摘　　要：针对群组协作模式下多学科协同产品设计过程的需求,开发一个纯软件的多点网络视频会议系统。采用类B/S结构设计。基于Java媒体框架(JMF)和流媒体技术,完成系统框架设计、功能设计和媒体流交互过程的管理与控制机制,并实现与产品数据管理(PDM)系统的集成。系统提供了多学科协同过程知识交流与共享、设计冲突消解的实时多媒体应用环境。To meet the requirement of multi-disciplinary collaborative product design process based on group collaboration mode, a pure software muhipoint network video conference system was developed. The system conception adopts a structure similar to Browser/Server （ B/ S）. Java Media Framework （JMF） and streaming media transmission and control technology were introduced in the system. System framework design and function design were achieved. Interactive processes management and control mechanism was implemented among media streams of clients＇ browsers. The video conference system was integrated with previous developed Product Data Management （PDM） system. It provides a real-time multimedia application environment for knowledge intercommunion and sharing, design conflict resolution in multi-disciplinary collaborative process.
