【摘要】：IPTV即交互式網(wǎng)絡(luò)電視，是一種利用寬帶有線電視網(wǎng)，集互聯(lián)網(wǎng)、多媒體、通訊等技術(shù)于一體，通過(guò)外置機(jī)頂盒或內(nèi)置模塊向家庭用戶提供包括數(shù)字電視在內(nèi)的多種交互式服務(wù)的嶄新技術(shù)。IPTV的主要賣(mài)點(diǎn)是交互式操作，可以非常容易地將電視服務(wù)、互聯(lián)網(wǎng)瀏覽、音視頻流媒體服務(wù)，以及多種在線信息咨詢、娛樂(lè)、教育、培訓(xùn)及商務(wù)功能結(jié)合在一起，在未來(lái)的競(jìng)爭(zhēng)中處于十分有利的優(yōu)勢(shì)地位。 平板電腦是一種小型、方便攜帶的個(gè)人電腦，以觸摸屏作為基本的輸入設(shè)備。它擁有的觸摸屏（也稱為數(shù)位板技術(shù)）允許用戶通過(guò)觸控筆或數(shù)字筆來(lái)進(jìn)行作業(yè)而不是傳統(tǒng)的鍵盤(pán)或鼠標(biāo)。用戶可以通過(guò)內(nèi)建的手寫(xiě)識(shí)別、屏幕上的軟鍵盤(pán)、語(yǔ)音識(shí)別或者一個(gè)真正的鍵盤(pán)（如果該機(jī)型配備的話）�？梢酝耆敲酪粋�(gè)普通的PC個(gè)人電腦。 目前，隨著移動(dòng)互聯(lián)網(wǎng)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(dòng)性及強(qiáng)大的交互能力，使之成為網(wǎng)絡(luò)遠(yuǎn)程移動(dòng)教育最合適的載體。Android是國(guó)內(nèi)外平板電腦目前最主流的操作系統(tǒng)，2013年已經(jīng)發(fā)展到Android4.2.2，其易用性正不斷被大眾所認(rèn)可，是移動(dòng)智能終端的首選平臺(tái)。 基于IPTV和安卓平板電腦的多屏互動(dòng)網(wǎng)絡(luò)學(xué)習(xí)系統(tǒng)融合了互動(dòng)電視教育與現(xiàn)代網(wǎng)絡(luò)遠(yuǎn)程教育的優(yōu)點(diǎn)，老師和學(xué)生可以通過(guò)學(xué)習(xí)平臺(tái)，利用大屏幕電視機(jī)及手中的移動(dòng)平板電腦，不但可以實(shí)現(xiàn)實(shí)時(shí)雙向互動(dòng)的遠(yuǎn)程教學(xué)，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(dòng)網(wǎng)絡(luò)學(xué)習(xí)系統(tǒng)，主要包括系統(tǒng)架構(gòu)、課件制作、資源管理、在線教學(xué)、教學(xué)管理、系統(tǒng)Portal、學(xué)習(xí)評(píng)測(cè)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(xué)資源管理模塊使用MySql數(shù)據(jù)庫(kù)實(shí)現(xiàn)元數(shù)據(jù)及資源的存儲(chǔ)和查詢。在線教學(xué)模塊向?qū)W習(xí)者提供課程學(xué)習(xí)、在線答疑、語(yǔ)音視頻交互、數(shù)據(jù)統(tǒng)計(jì)分析等交互功能；課件學(xué)習(xí)包括視頻課程學(xué)習(xí)和交互式圖文資料學(xué)習(xí)兩種類型。教學(xué)管理模塊是對(duì)教學(xué)系統(tǒng)Portal、在線教學(xué)的支撐和輔助管理，提供信息管理、知識(shí)體系管理、課程教學(xué)管理、在線習(xí)題管理以及數(shù)據(jù)統(tǒng)計(jì)分析等功能。 本文首先論述了IPTV平臺(tái)及Android平板電腦的概念、特點(diǎn)、發(fā)展及其在電視教育領(lǐng)域的應(yīng)用。研究了編碼、CDN、EPG、機(jī)頂盒等IPTV核心關(guān)鍵技術(shù)。以及Android的界面、后臺(tái)服務(wù)、廣播及數(shù)據(jù)保存等核心關(guān)鍵技術(shù)。然后，對(duì)基于IPTV和安卓平板電腦的多屏互動(dòng)網(wǎng)絡(luò)學(xué)習(xí)系統(tǒng)的設(shè)計(jì)目標(biāo)和原則進(jìn)行了探討，，提出了學(xué)習(xí)系統(tǒng)的總體結(jié)構(gòu)設(shè)計(jì)，并對(duì)關(guān)鍵模塊進(jìn)行了詳細(xì)的設(shè)計(jì)，研究了可以實(shí)現(xiàn)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(xué)習(xí)系統(tǒng)實(shí)施區(qū)域教育資源整合，優(yōu)化整合現(xiàn)代中小學(xué)遠(yuǎn)程電視教育的應(yīng)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.
