Dynamic EPG Implementation for Ubiquitous Environment

摘要

In this paper, we proposed EPG as a suitable method for digital broadcasting in a ubiquitous environment. As an application technique for user custom UI service in a Ubiquitous Environment, a dynamic EPG presentation technique was studied. To accomplish this, a context structure definition and presentation engine to present it was needed. The UI context information consists of various graphic component data, such as position, font, size, shape, etc., used to draw EPG GUI on a screen using UIML language. Context information was defined and the technique for presenting on a screen was studied. Also, the digital broadcasting field was applied for demonstration of Dynamic EPG and finally the paper proved that this can be used as a part of core technique for the ubiquitous dynamic EPG service. Consequently, it was a good idea to change the UI framework configuration based on context information made by someone and send it to a rendering engine for displaying user custom UI.
