【摘要】：IPTV即交互式网络电视，是一种利用宽带有线电视网，集互联网、多媒体、通讯等技术于一体，通过外置机顶盒或内置模块向家庭用户提供包括数字电视在内的多种交互式服务的崭新技术。IPTV的主要卖点是交互式操作，可以非常容易地将电视服务、互联网浏览、音视频流媒体服务，以及多种在线信息咨询、娱乐、教育、培训及商务功能结合在一起，在未来的竞争中处于十分有利的优势地位。平板电脑是一种小型、方便携带的个人电脑，以触摸屏作为基本的输入设备。它拥有的触摸屏（也称为数位板技术）允许用户通过触控笔或数字笔来进行作业而不是传统的键盘或鼠标。用户可以通过内建的手写识别、屏幕上的软键盘、语音识别或者一个真正的键盘（如果该机型配备的话）。可以完全媲美一个普通的PC个人电脑。目前，随着移动互联网的不断发展，拥有WIFI和3G模块的平板电脑所拥有的便携性、移动性及强大的交互能力，使之成为网络远程移动教育最合适的载体。Android是国内外平板电脑目前最主流的操作系统，2013年已经发展到Android4.2.2，其易用性正不断被大众所认可，是移动智能终端的首选平台。基于IPTV和安卓平板电脑的多屏互动网络学习系统融合了互动电视教育与现代网络远程教育的优点，老师和学生可以通过学习平台，利用大屏幕电视机及手中的移动平板电脑，不但可以实现实时双向互动的远程教学，还可以跨屏幕一起协作完成作业和答疑解惑。本文基于IPTV和安卓平板电脑的多屏互动网络学习系统，主要包括系统架构、课件制作、资源管理、在线教学、教学管理、系统Portal、学习评测等模块。课件制作模块完成课件的采集、制作等管理工作。教学资源管理模块使用MySql数据库实现元数据及资源的存储和查询。在线教学模块向学习者提供课程学习、在线答疑、语音视频交互、数据统计分析等交互功能；课件学习包括视频课程学习和交互式图文资料学习两种类型。教学管理模块是对教学系统Portal、在线教学的支撑和辅助管理，提供信息管理、知识体系管理、课程教学管理、在线习题管理以及数据统计分析等功能。本文首先论述了IPTV平台及Android平板电脑的概念、特点、发展及其在电视教育领域的应用。研究了编码、CDN、EPG、机顶盒等IPTV核心关键技术。以及Android的界面、后台服务、广播及数据保存等核心关键技术。然后，对基于IPTV和安卓平板电脑的多屏互动网络学习系统的设计目标和原则进行了探讨，，提出了学习系统的总体结构设计，并对关键模块进行了详细的设计，研究了可以实现的方法途径。最后，以广东电信IPTV电视教育为例，提出了利用此学习系统实施区域教育资源整合，优化整合现代中小学远程电视教育的应用模式。
[Abstract]:IPTV is an interactive network television, is a use of broadband cable television network, the collection of Internet, multimedia, communications and other technologies in one. A new technology for providing a variety of interactive services, including digital TV, to home users through an external set-top box or built-in module. The main selling point of IPTV is interactive operation, which can be easily integrated into television services. Internet browsing, audio and video streaming services, as well as a variety of online information consulting, entertainment, education, training and business functions together, in the future of competition in a very favorable position. A tablet is a small, portable personal computer. Touch screen as the basic input device. It has a touch screen (also known as digital board technology). Allows users to work through a stylus or a digital pen instead of a traditional keyboard or mouse. Users can use built-in handwritten recognition. A soft keyboard, voice recognition, or a real keyboard on the screen (if the model is equipped). It is comparable to an ordinary PC PC. At present, with the continuous development of the mobile Internet, tablets with WIFI and 3G modules have the portability, mobility and powerful interactive capabilities. Android is the most popular operating system for tablets at home and abroad. In 2013, it has been developed to Android4.2.2. Its ease of use is continuously recognized by the public, is the first choice platform for mobile intelligent terminals. The multi-screen interactive online learning system based on IPTV and Android tablets combines the advantages of interactive television education and modern online distance education. Teachers and students can use the learning platform. By using the large-screen TV and the mobile tablet computer, it can not only realize the real-time two-way interactive distance teaching, but also work together across the screen to complete the homework and answer questions. This paper is based on IPTV and Android tablet multi-screen interactive network learning system, including system architecture, courseware making, resource management, online teaching, teaching management, system Portal. Learning and evaluation modules. Courseware making module to complete the collection of courseware. The teaching resource management module uses MySql database to store and query metadata and resources. The online teaching module provides learners with course learning, online question answering, voice and video interaction. Data statistical analysis and other interactive functions; Courseware learning includes two types: video course learning and interactive graphics and text materials learning. The teaching management module provides information management for the teaching system Portal, the support and assistant management of online teaching. Knowledge system management, course teaching management, online exercise management and data statistical analysis and other functions. This paper first discusses the concept, characteristics, development and application of IPTV platform and Android tablet computer in the field of television education. IPTV core key technologies, such as set-top box. And Android interface, background services, broadcast and data storage and other core key technologies. Then. This paper discusses the design goals and principles of the multi-screen interactive network learning system based on IPTV and Android tablet computer, puts forward the overall structure design of the learning system, and designs the key modules in detail. Finally, take Guangdong Telecom IPTV TV education as an example, put forward the use of this learning system to implement the integration of regional education resources. Optimize and integrate the application mode of distance television education in modern middle and primary schools.
