    • In a navigation system displaying a traffic information in which an information processing device (1) and a display (2) are mounted on a moving body, a format for a traffic information and an information belonging thereto is standardized between different types of navigation devices. Application programs for processing information written in the standardized format are loaded in a common intermediate code between different types of navigation devices. The information processing device includes a converting means which reads-in the application programs written in the intermediate code and converts the same into application programs specific to the current navigation device and means for partially replacing and supplementing the application programs written in the intermediate code via an information medium. Whereby, when modifying and/or supplementing of such as a traffic information for a navigation system, the revision of application programs necessary for processing the same is simplified and realized with a low cost and a traffic information and an information belonging thereto are broadly provided while eliminating a device type dependency.
    • 在显示信息处理装置(1)和显示器(2)安装在移动体上的交通信息的导航系统中,在不同类型的导航装置之间对交通信息的格式和属于其的信息进行标准化。 用于处理以标准格式编写的信息的应用程序被加载到不同类型的导航装置之间的公共中间代码中。 该信息处理装置包括一个转换装置,用于读取写在中间代码中的应用程序并将其转换成对当前导航装置专用的应用程序,以及用于部分地替换和补充通过中间代码写入的应用程序的装置, 信息媒介。 由此,在对导航系统的交通信息进行修改和/或补充的情况下,对于处理所需要的应用程序的修改被简化并且以低成本和交通信息实现,并且广泛地提供属于其的信息,同时 消除了设备类型的依赖。
