【摘要】：當前,在政府的支持下,國產(chǎn)基礎(chǔ)軟件得到了大力發(fā)展,開發(fā)了國產(chǎn)Linux操作系統(tǒng)和一些應(yīng)用軟件,但國產(chǎn)基礎(chǔ)軟件平臺上的數(shù)字化資源依然比較匱乏。由于平臺之間的差異,Windows平臺上的資源無法直接在Linux平臺上運用。為豐富國產(chǎn)基礎(chǔ)軟件平臺上的數(shù)字化資源,并且低成本開發(fā),可以采用移植與轉(zhuǎn)換的技術(shù)將Windows平臺上的資源有效運用在Linux平臺上。三分屏課件在遠程教育領(lǐng)域中有著廣泛的應(yīng)用,是重要的教育資源。Windows平臺上的三分屏課件平滑移植到Linux平臺上將豐富國產(chǎn)基礎(chǔ)軟件平臺上的教育資源,可為以數(shù)字教育應(yīng)用拉動國產(chǎn)基礎(chǔ)軟件平臺的推廣與使用的戰(zhàn)略做出貢獻。 三分屏課件從Windows到Linux跨平臺移植存在的問題：三分屏課件模板形式多樣；Linux不支持Jscript等腳本語言和某些HTML標簽及WMV、ASF視頻格式等等；跨平臺移植方法的選擇；同步控制的設(shè)計等。 本論文的主要研究工作： (1)在結(jié)合三分屏課件資源結(jié)構(gòu)特點和當前的移植技術(shù)的基礎(chǔ)上,提出了三分屏課件從Windows到Linux平滑移植的方法,并且針對三類典型的Windows三分屏課件提出了相應(yīng)的轉(zhuǎn)換模型。 (2)重新設(shè)計三分屏課件的物理結(jié)構(gòu)及邏輯結(jié)構(gòu),重點討論了XML文件結(jié)構(gòu)設(shè)計和同步控制策略。 (3)主要討論了以下功能的實現(xiàn)：從網(wǎng)頁中提取文本信息、從視頻中提取提示點信息、視頻格式轉(zhuǎn)換、生成XML文件、同步控制實現(xiàn)、復(fù)制模板。 (4)在三分屏課件移植模型研究的基礎(chǔ)上設(shè)計并實現(xiàn)了三分屏課件轉(zhuǎn)換工具,并且對該轉(zhuǎn)換工具進行了功能測試。 本論文的特色和創(chuàng)新之處在于：采用跨平臺語言Flash ActionScript語言實現(xiàn)同步控制,以及使用XML技術(shù)實現(xiàn)三分屏課件模板與數(shù)據(jù)分離。為以后三分屏課件從Windows到Linux跨平臺移植研究提供了參考,實現(xiàn)的轉(zhuǎn)換工具可以轉(zhuǎn)換Windows上大量的三分屏課件,合理有效的重用了Windows平臺上的資源,節(jié)省了三分屏課件開發(fā)成本。 本文的研究依托于“核高基”(核心電子器件、高端通用芯片及基礎(chǔ)軟件產(chǎn)品)項目子課題“面向國產(chǎn)基礎(chǔ)軟件的數(shù)字教育平滑移植研究及應(yīng)用”。
[Abstract]:At present, with the support of the government, the domestic basic software has been greatly developed, the domestic Linux operating system and some application software have been developed, but the digital resources on the domestic basic software platform are still relatively scarce. Because of the difference between platforms, the resources on Windows platform can not be directly used on Linux platform. In order to enrich the digital resources on the domestic basic software platform and develop at low cost, the technology of transplantation and transformation can be adopted to effectively use the resources on the Windows platform on the Linux platform. Three-screen courseware is widely used in the field of distance education. It is an important educational resource. The three-screen courseware on Windows platform is transplanted smoothly to Linux platform, which will enrich the educational resources on the domestic basic software platform. It can contribute to the strategy of popularizing and using the domestic basic software platform based on the application of digital education. The problems existing in the cross-platform migration of three-point courseware from Windows to Linux include that the three-point courseware template does not support script languages such as Jscript, some HTML tags and WMV / ASF video formats, the selection of cross-platform porting methods and the design of synchronization control, etc. The main research work of this thesis is as follows: 1) based on the characteristics of three-point courseware resource structure and the current transplantation technology, this paper puts forward the method of smooth transplantation from Windows to Linux, and puts forward the corresponding transformation model for three typical Windows three-screen courseware. 2) redesigning the physical structure and logic structure of the three-screen courseware, and emphatically discussing the design of XML file structure and synchronization control strategy. This paper mainly discusses the realization of the following functions: extracting text information from web page, extracting prompt point information from video, converting video format, generating XML file, realizing synchronization control and copying template. 4) on the basis of the research on the transplantation model of three-point courseware, the paper designs and implements the three-point screen courseware conversion tool, and tests the function of the conversion tool. The features and innovations of this paper lie in the use of cross-platform language Flash ActionScript to realize synchronization control, and the use of XML technology to realize the separation of three-point courseware template and data. This paper provides a reference for the research of cross-platform transplantation of three-point screen courseware from Windows to Linux. The realized conversion tool can convert a large number of three-screen courseware on Windows, reasonably and effectively reuse the resources on Windows platform, and save the development cost of three-point screen courseware. The research of this paper is based on the project "Research and Application of Digital Education smooth Transplantation for domestic basic Software" (Core Electronic Devices, High-end Universal chips and basic Software products).
