尋求一移植多媒體講解播放器至各種裝置之方法論-以iOS平台為例

Abstract

隨著軟體版權問題在國內日益受重視，許多中小企業，陸續計畫改以免費軟體當作資訊處理的工具。然而，免費軟體的使用只能解決部分的問題，對於客製軟體的需求，不論是企業組織乃至於個人，從沒間斷過。 在軟體領域裡，只要裝置有兩種以上的作業系統，「移植」(porting)的工作就會一直存在。開發人員花了費盡千辛萬苦開發完A平台的程式之後，又要再花另一番工夫搬到B平台上，這個工程是非常繁瑣的；可以輕鬆快速地把程式跨平台移植的例子是少之又少，未來希望能改變這一切，並朝這方向前進。 在特定平台上所開發的種種客製化軟體系統（如MS Windows平台），不會因為有免費軟體的使用而被完全取代。要解決這樣兩難的問題，最直接、最快速也是最經濟的方法就是進行「異質作業環境下的軟體移植」，而移植方法和工具的提出，恰能適時地在此轉型期發揮關鍵性的角色。

With the software copyright issues in the country is increasingly important, many SMEs successively change free software as a tool for information processing system. However, the use of free software can only solve part of the problems. The demand for custom software never stopped whether corporate organizations and even individuals. In the software field, as long as the device has two or more operating systems, “Porting” would have been. IT developer exhausted finished the program of the A platform, but also to spend another lot of effort to move to the B platform, this project is very tedious. That a project can quickly and easily be ported across platforms is also less. In the future, hope for improving this and proceeding forward in this direction. The free software will not completely replace customized software developed on specific platform, such as “MS Windows” platform. To solve such a dilemma, the most direct, fastest and most economical way is porting the software across heterogeneous environment, “Porting” methods and procedures proposed, just a timely manner, play a key role. This study will explore “The Multimedia Presentation Lecturing Player” method of porting in a variety of heterogeneous platforms, analysis of the porting procedure, and induction and define a variety of platforms available law to application porting, known as porting methodology. According to this methodology and Context Awareness and Content Adaptation mechanism, porting Lecturing Player to iOS platform, and integration with the most popular Cloud Storage, the Dropbox, and implement on iPad2 as a porting target device.
