摘　　要：文章根据人造复杂系统的特性和人的认知规律,提出了一个基于对象的多媒体认知软件系统数据模型。数据模型由媒体存取层、多媒体对象层和多媒体表现层和多媒体应用层构成。这种层次模型将媒体异构环境存取、多媒体对象处理和语义合成表现以及各种时序关系等问题在不同层次分别进行处理,使软件系统具有很好的灵活性和可复用性。In this paper,a model for multimedia cognitive systems based on objects is presented according to the char-acter of complex systems and the cognition of man.The system is composed of the multimedia data access layer,the multimedia data definition layer,the multimedia data re-presentation layer and the application layer.The layered model respectively provides media access in heterogeneous platforms ,multimedia object process and semantics composition ser-vices and the special problems in multimedia systems such as synchronization on different layers,makes the multimedia system software having better reusability.
