【摘要】：当前,在政府的支持下,国产基础软件得到了大力发展,开发了国产Linux操作系统和一些应用软件,但国产基础软件平台上的数字化资源依然比较匮乏。由于平台之间的差异,Windows平台上的资源无法直接在Linux平台上运用。为丰富国产基础软件平台上的数字化资源,并且低成本开发,可以采用移植与转换的技术将Windows平台上的资源有效运用在Linux平台上。三分屏课件在远程教育领域中有着广泛的应用,是重要的教育资源。Windows平台上的三分屏课件平滑移植到Linux平台上将丰富国产基础软件平台上的教育资源,可为以数字教育应用拉动国产基础软件平台的推广与使用的战略做出贡献。三分屏课件从Windows到Linux跨平台移植存在的问题：三分屏课件模板形式多样；Linux不支持Jscript等脚本语言和某些HTML标签及WMV、ASF视频格式等等；跨平台移植方法的选择；同步控制的设计等。本论文的主要研究工作： (1)在结合三分屏课件资源结构特点和当前的移植技术的基础上,提出了三分屏课件从Windows到Linux平滑移植的方法,并且针对三类典型的Windows三分屏课件提出了相应的转换模型。 (2)重新设计三分屏课件的物理结构及逻辑结构,重点讨论了XML文件结构设计和同步控制策略。 (3)主要讨论了以下功能的实现：从网页中提取文本信息、从视频中提取提示点信息、视频格式转换、生成XML文件、同步控制实现、复制模板。 (4)在三分屏课件移植模型研究的基础上设计并实现了三分屏课件转换工具,并且对该转换工具进行了功能测试。本论文的特色和创新之处在于：采用跨平台语言Flash ActionScript语言实现同步控制,以及使用XML技术实现三分屏课件模板与数据分离。为以后三分屏课件从Windows到Linux跨平台移植研究提供了参考,实现的转换工具可以转换Windows上大量的三分屏课件,合理有效的重用了Windows平台上的资源,节省了三分屏课件开发成本。本文的研究依托于“核高基”(核心电子器件、高端通用芯片及基础软件产品)项目子课题“面向国产基础软件的数字教育平滑移植研究及应用”。
[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).
