基于Java技术的数字电视图形显示模型的研究与设计

Study and design of digital TV graphics model based on Java technology

图形显示模型设计是数字电视中间件系统开发中的关键。提出了一种基于Java技术的数字电视图形显示模型方案,介绍了该模型的框架结构以及实现该模型所需的类库轻量化改造、类库重新配置、本地窗口系统适配、多媒体图形库等关键技术。实验证明了设计的可行性。

The design of graphics model is crucial to the implementation of DTV middleware.We present a DTV graphics model based on Java technology.The structure of the model and the key technologies used such as classes lightweight-trans-forming,reconfiguration,native window system adapter and multimedia library are also proposed.The testing results demon-strate the effectiveness of the design.[
