【摘要】：IPTV即交互式網絡電視，是一種利用寬帶有線電視網，集互聯網、多媒體、通訊等技術于一體，通過外置機頂盒或內置模塊向家庭用戶提供包括數字電視在內的多種交互式服務的嶄新技術。IPTV的主要賣點是交互式操作，可以非常容易地將電視服務、互聯網瀏覽、音視頻流媒體服務，以及多種在線信息咨詢、娛樂、教育、培訓及商務功能結合在一起，在未來的競爭中處于十分有利的優(yōu)勢地位。 平板電腦是一種小型、方便攜帶的個人電腦，以觸摸屏作為基本的輸入設備。它擁有的觸摸屏（也稱為數位板技術）允許用戶通過觸控筆或數字筆來進行作業(yè)而不是傳統(tǒng)的鍵盤或鼠標。用戶可以通過內建的手寫識別、屏幕上的軟鍵盤、語音識別或者一個真正的鍵盤（如果該機型配備的話）。可以完全媲美一個普通的PC個人電腦。 目前，隨著移動互聯網的不斷發(fā)展，擁有WIFI和3G模塊的平板電腦所擁有的便攜性、移動性及強大的交互能力，使之成為網絡遠程移動教育最合適的載體。Android是國內外平板電腦目前最主流的操作系統(tǒng)，2013年已經發(fā)展到Android4.2.2，其易用性正不斷被大眾所認可，是移動智能終端的首選平臺。 基于IPTV和安卓平板電腦的多屏互動網絡學習系統(tǒng)融合了互動電視教育與現代網絡遠程教育的優(yōu)點，老師和學生可以通過學習平臺，利用大屏幕電視機及手中的移動平板電腦，不但可以實現實時雙向互動的遠程教學，還可以跨屏幕一起協(xié)作完成作業(yè)和答疑解惑。 本文基于IPTV和安卓平板電腦的多屏互動網絡學習系統(tǒng)，主要包括系統(tǒng)架構、課件制作、資源管理、在線教學、教學管理、系統(tǒng)Portal、學習評測等模塊。課件制作模塊完成課件的采集、制作等管理工作。教學資源管理模塊使用MySql數據庫實現元數據及資源的存儲和查詢。在線教學模塊向學習者提供課程學習、在線答疑、語音視頻交互、數據統(tǒng)計分析等交互功能；課件學習包括視頻課程學習和交互式圖文資料學習兩種類型。教學管理模塊是對教學系統(tǒng)Portal、在線教學的支撐和輔助管理，提供信息管理、知識體系管理、課程教學管理、在線習題管理以及數據統(tǒng)計分析等功能。 本文首先論述了IPTV平臺及Android平板電腦的概念、特點、發(fā)展及其在電視教育領域的應用。研究了編碼、CDN、EPG、機頂盒等IPTV核心關鍵技術。以及Android的界面、后臺服務、廣播及數據保存等核心關鍵技術。然后，對基于IPTV和安卓平板電腦的多屏互動網絡學習系統(tǒng)的設計目標和原則進行了探討，，提出了學習系統(tǒng)的總體結構設計，并對關鍵模塊進行了詳細的設計，研究了可以實現的方法途徑。最后，以廣東電信IPTV電視教育為例，提出了利用此學習系統(tǒng)實施區(qū)域教育資源整合，優(yōu)化整合現代中小學遠程電視教育的應用模式。
[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.
