隨著各種行動裝置的普及化，整合現存的系統到不同的裝置上是有需要的。如何無接縫地去接合現有的系統到具備網路能力但資源有限的裝置上是一個值得研究的課題。內容格式適合化的技術在解決這個問題上扮演一個重要的角色。在這篇論文中，我們提出了一個內容格式適合化的系統，用來轉換呈現系統運算結果的Frame成為符合裝置特性與使用者需求的圖形格式。它可以允許多種不同的行動裝置去接收和呈現來自於現有軟體或系統的執行結果。我們的系統並具備了其他大部份內容格式適合化系統所缺乏的互動性功能，用來支援現有系統或軟體與行動裝置之間的互動。

With the popularity of diverse mobile devices, integrating existing systems or softwares of personal computers with different devices is an active research. Transcoding plays an important role in this issue. In the thesis, we develop a transcoding system that converts frames based on the device profile and user’s preferences to present retrieved results of existing systems into image format. The proposed system allows a variety of mobile devices to efficiently display the retrieved results from existing systems. To overcome the weakness of the lack for interaction of existing transcoding systems, our proposed system supports interaction between clients and server.
