【摘要】：在线教育平台(E-Learning)是经过在互联网上建设网站教育教学平台供在线者学习的一种方法。通过互联网方式实现在线学习者可以不受地域和时间限制接受教育的要求。随着在线教育平台方式的进一步推广,在线教育平台在使用过程中出现例如平台系统搭建各自为政、各地域教育信息化资源分布不公平、各个学习平台间存在系统孤岛等问题。云计算功能为有效地解决以上情况提供了一种可行的途径。云计算通过大量计算机群组组成,利用分布式的计算方法和虚拟化技术将软、硬件资源虚拟化成一个统一的资源池。截止现在市场上成熟的云计算系统平台拥有百万台级别的服务器组成服务器集群,可以提供超快的计算能力和海量存储。本文主要研究在线教育平台设计与实现,结合多媒体和云计算的部分服务与特点,设计出基于多媒体技术构建本校实际需求的在线教育平台的研究方案,并在现有使用的学习资源平台上使用Google App Engine技术设计开发一套统一、开放的在线教育平台系统,目标是改变过时的网络学习系统中存在的各种缺陷。本文重点论述内容包括如下几个方面:(1)针对多媒体技术、云计算、Google App Engine核心架构及其提供的各种接口服务进行深入研究和分析工作;(2)应用Eclipse集成开发环境、Google App Engine开发平台、Java Web开发技术实现云学习平台各个主要功能模块,并针对系统业务逻辑、系统功能界面、系统安全、数据持久化等问题的具体解决实现进行描述;(3)利用多媒体技术实现教育发布平台上的多渠道内容汇编功能,聚合课堂教学资源、优秀的网上视频资源。然后将聚合的内容进行制作加工、转码发布,最终形成待发布的教学节目;(4)利用多媒体技术实现教育发布平台对各种教学视频、时政视频等音视频资源的内容发布,包括教学内容节目单编排、推送、直播、点播等服务。本文基于实际需求设计并实现多媒体融合平台的各个主要功能模块,利用Google App Engine开发平台优势和成熟的Java Web技术解决了基于多媒体技术构建的在线教育平台在实际搭建过程中各种问题。
[Abstract]:E-Learning, an online education platform, is a way to build an educational platform on the Internet for online learners to learn. Through the Internet, online learners can be free from geographical and time constraints to receive education. With the further promotion of the online education platform, the online education platform appears in the process of using, such as the platform system to build their own policies, the distribution of information resources in different regions of education is not fair, and there are some problems such as the isolated islands among the learning platforms and so on. Cloud computing provides a feasible way to solve the above problem effectively. Cloud computing consists of a large number of computer groups, using distributed computing methods and virtualization technology to virtualize the hardware and software resources into a unified pool of resources. Up to now, the mature cloud computing system platform in the market has millions of servers to form a cluster of servers, which can provide super fast computing power and mass storage. This paper mainly studies the design and implementation of online education platform, combining some services and characteristics of multimedia and cloud computing, designs a research scheme of online education platform based on multimedia technology. A unified and open online education platform system is designed and developed by using Google App Engine technology on the existing learning resource platform. The goal is to change all kinds of defects in the outdated e-learning system. This paper focuses on the following aspects: 1) aiming at multimedia technology, The research and analysis of the core architecture and various interface services provided by App Engine in cloud computing. (2) the application of the Eclipse integrated development environment to the implementation of the main function modules of the cloud learning platform based on the App Engine development platform and the Java Web development technology. It also describes how to solve the problems such as system business logic, system function interface, system security, data persistence and so on. The multimedia technology is used to realize the multi-channel content compilation function on the educational publishing platform. Aggregate classroom teaching resources, excellent online video resources. Then the aggregated content is produced, processed, transcoded, and finally, the teaching program to be published is formed. The multimedia technology is used to realize the release of the contents of various audio and video resources, such as teaching video, current politics and video, on the educational publishing platform. Including teaching content program layout, push, live, on demand and other services. This paper designs and implements the main functional modules of the multimedia fusion platform based on the actual requirements. The advantages of Google App Engine development platform and mature Java Web technology are used to solve all kinds of problems in the process of building online education platform based on multimedia technology.
