| 摘 要： | 针对分布式视频会议，提出了一个基于对象的分层系统模型，描述了组成系统的各种构件的对象化方法和多媒体间的语义关系。这种模型将多媒体数据流在Ｉ／Ｏ级、处理级和传输网络级进行对象分解。多个对象的分布处理，易于按数据流编程实现，能很好地适应编程环境和网络环境。该模型可充分开发不同粒度的并行性，使媒体处理满足实时应用的需求，程序模块具有很好的可重用性，有利于不同操作环境下系统的实现及互通。

| Abstract: | A video conference system is developed using a layered model. Object oriented components and semantic relations among multimedia are specified. The model decomposes the multimedia data into a set of objects at the I/O level, processing level, transport level and network level, respectively, where different objects could be handled simultaneously. It is easy to implement the system by data flow programming; it is adaptive to programming and networking environments. Based on this model, the parallelisms with various granularities could be exploited for real time applications. The program modules based on the model have a good reusability such that systems under different operational environments could be developed easily, and this facilitates intercommunications. |
