分布式多媒体系统中对象表示模型及变换方法研究

Specification Models and Transformation of Multimedia Objects in Distributed Multimedia Systems

在设计一个分布式多媒体系统时 ,具有挑战性的问题之一是如何在系统的不同层次为各模式设计合适的规格描述模型 ,并提供不同模型的变换方法和媒体的集成与同步策略 .在本文中 ,我们给出了几种多媒体对象的表示模型和变换算法 ,它们把高层的多媒体对象变换成可以用来支持多媒体对象展示和通信的实用模式 ,在该模式中能较好地保持多媒体对象的集成与同步特性 .

One of the challenges in the design of a distributed multimedia system is devising suitable specification models for various schemas in different levels.Another important research issue is devising transformation and the integration and synchronization of multimedia object.In this paper, we present specification models for multimedia objects and transformation algorithm.The high level multimedia objects are transformed into schemas that can be used to support the presentation and communication of multimedia objects.The models are preferably able to keep the integration and synchronization of multimedia object.
