RIA: User Interface Toolkit Architectures for Distributed Multimedia Applications

研究支持分布式和协作多媒体应用程序的两个体系结构工具包组件：1)通过分布式事件模型进行多媒体控制和协作，以及2)作为小部件高级替代品的可嵌入应用程序。在集中式调度程序、调度程序集群和多调度程序三种不同负载下，对分布式事件模型进行了研究和测试。使用数据共享、输入共享和输出共享来考虑协作。可嵌入应用程序的使用将小部件扩展到编程控制和用户界面控制。可嵌入应用程序与普通小部件的区别在于，可嵌入应用程序可以直接使用，也可以组成更大的应用程序，然后可能被更高级别的接口取代。该项目包括设计、实现和测试一个通用的可嵌入应用程序类以及几个特定的可嵌入应用程序。

To investigate two architectural toolkit components to support distributed and collaborative multimedia applications: 1) multimedia control and collaboration via distributed event models, and 2) embeddable applications as a high level replacement for widgets. Distributed event models are studied and tested under different loads in three categories: centralized dispatcher, dispatcher clusters, and multiple dispatchers. Collaboration is considered using data sharing, input-sharing, and output sharing. The use of embeddable applications extends widgets to both programmatic control and user interface control. The difference of embeddable applications with ordinary widgets is that embeddable applications can be used directly or can be composed into larger applications and then possibly replaced by a higher level interface. The project includes the design, implementation, and test of a general embeddable application class along with several specific embeddable applications.
