基于控制实体的多媒体多用户通信模型

A MULTIMEDIA MULTIUSER COMMUNICATION MODEL BASED ON CONTROL ENTITY

本文提出了一个有效支持多媒体多用户应用的新通信模型 ,并给出了该模型的形式化描述 ,以及相应的实体级控制操作 ,TC控制操作 ,GTC控制操作的规则 .该模型支持不同类型的多媒体多用户应用并为各种通信服务提供了更为结构化的控制 .同时 ,由于该模型的抽象化定义 ,使得它更容易适应新的通信环境 ,扩充到新的类型服务中去 .文章最后还给出了基于该模型的桌面多媒体会议的应用实例 .

This paper proposes a new communication model that supports multimedia multiuser applications effectively. It provides a formal description of this model and presents the rules of relative entity level operations, TC level operations, and GTC level operations respectively. This communication model provides a variety of communication services with more structured control. Common interface using this model can support a different types of multimedia multiuser applications. Otherwise, because of the abstract definition of this model, it is easier to adapt to new environment and be extended to new kinds of services. Last, this paper also give a desktop multimedia conference application case that based on this new communication model.
