An IPTV Set-top box enables the possibility of doing much more than decodingtelevision content. Its Ethernet interface gives it the same possibilities to communicatewith the outside world as any network device. This enables a wide rangeof services from internet radio to acting as a digital media receiver in your homenetwork. These highly interactive services increase the demands for responsiveand visually attractive user interfaces.Due to the cost-sensitive market of IPTV STBs the preferred platform to developthe user interface is the HTML browser as it allows for fast developmenttimes and low costs. As a W3C standard it also offers high portability and hardwareabstraction making it easy to use more than one STB vendor. The cons ofHTML based GUIs are low performance and lacklustre graphics.This thesis aims to find out if SVG can be used to achieve rich, scalable and animatedgraphics with high performance and still keep the attractive characteristicsof HTML.To do this much effort was put into identifying the strenghts and weaknesses ofSVG. The lessons learned resulted in an SVG AJAX framework called TOIXSVGmaking it possible to develop SVG GUIs in the same manner as modern Rich InternetApplications, enabling component reuse to make sure development time scalespreferably with the scope and complexity of the user interface. Along with theframework several new widgets had to be developed to achieve the targeted functionality.As a proof of concept a mock-up GUI was created with the frameworkand widgets.

When developing HTML5 applications for TV platforms, the TV platforms provide, in addition to standardHTML5 functionality, also extra APIs for TV-specific features. These extra APIs differ between TVplatforms, and that is a problem when developing an application targeting several platforms. This thesis hasexamined if it is possible to design a framework which provides the developer with one API that works formany platforms by wrapping their platform-specific code. The answer is yes. With success, platform-specificfeatures including: TV remote control input, video, volume, Internet connection status, TV channel streamsand EPG data have been harmonised under an API in a JavaScript library. Furthermore, a build systempackages the code in the way the platforms expect. The framework eases the development of TV platformHTML5 applications. At the moment, the framework supports the Pace, PC and Samsung Smart TVplatforms, but it can be extended with more TV platform back-ends. / Lorsque l’on développe des applications HTML5 pour des plateformes TV, les plateformes TV fournissent,en plus de la fonctionnalité standard d'HTML5, des APIs supplémentaires pour les particularités d'une TV.Ces APIs supplémentaires diffèrent entre les plateformes TV, et ceci cause un problème lors dudéveloppement d’une application pour plusieurs plateformes. Cette thèse a fait l’examen de la possibilité deconcevoir un cadre d'applications qui fournit au concepteur une API qui peut servir à plusieurs plateformes,cachant le code spécifique de celles-ci. La réponse est oui. On a réussi à harmoniser : l’entrée de latélécommande, le lecteur vidéos, le volume, la connexion Internet, le flux TV et leurs données GPE, dans uneAPI qui réside dans une bibliothèque JavaScript. En outre, un système de compilation met le code d’unemanière dont la plateforme peut comprendre. Le cadre d'applications facilite le développement d'applicationsHTML5 des plateformes TV. Pour le moment, le cadre d'applications peut supporter la Pace, le PC et laplateforme de Samsung Smart TV, mais il peut également fonctionner avec d'autres plateformes TV. / Wenn man HTML5-Anwendungen für TV-Plattformen entwickelt, stellen die Plattformen neben denStandardfunktionalitäten von HTML5 auch extra APIs für TV spezifische Features zur verfügung. Diesezuzätzlichen APIs unterscheiden zwischen TV-Plattformen und das ist ein Problem bei der Entwicklung vonAnwendungen, die auf mehreren Plattformen laufen sollen. Diese These untersucht, ob es möglich ist, einFramework zu entwerfen, dass dem Entwickler eine API bereitstellt, welche für mehrere Plattformenfunktioniert, indem deren Plattform spezifischer Code verpackt wird. Die Antwort ist ja. Das Frameworkharmonisiert: Fernbedienungeingabe, Video, Volumen, Internet-Anschlussstatus, Fensehkanalstreams undelektronische Programmführer, zu einer gemeinsamen JavaScript-Bibliothek-API. Weiterhin verpackt einbuild system den Code so, wie es die Plattform erwartet. Das Framework erleichtert die Entwicklung vonHTML5-Applikationen für TV-Plattformen. Im Moment deckt das Framework: Pace-, PC- und SamsungSmart TV-Plattformen, aber es kann mit weiteren TV-Plattformen erweitert werden. / Quando si sviluppano delle applicazioni HTML5 per le piattaforme TV, quest'ustime offrono, oltre allafunzionalità comune di HTML5, anche APIs addizionali per funzionalità specifiche della TV. Queste APIsaddizionali differiscono tra le varie piattaforme TV e questo è un problema quando si sviluppaun'applicazione che funzioni per ciascuna piattaforma. Il presente lavoro esamina la possibilità di progettareun framework che fornisca allo sviluppatore una sola API, la quale sia funzionante per molte piattaforme esia idonea a nascondere il codice specifico di ciascuna di esse. La risposta è sì. Il framework fonde:l'immissione del telecomando, il video, il volume, lo stato della connessione Internet, i flussi dei canali TV edei dati della guida elettronica dei programmi, all'interno di una API secondo il modello di una libreriaJavaScript. Inoltre, il sistema di compilazione crea un pacchetto del codice nel modo in cui le piattaforme siaspettano. Il framework facilita lo sviluppo di applicazioni HTML5 per le piattaforme TV. Al momento, ilframework sostiene le seguenti piatteforme: Pace, PC e Samsung Smart TV, ma può essere esteso anche adaltre. / När man utvecklar HTML5-applikationer för TV-plattformar, finns utöver HTML5s standardfunktionalitet,även extra APIer för att komma åt TV-specifika funktioner. Dessa extra APIer skiljer sig åt mellan TV-plattformar, och det är ett problem när man utvecklar en applikation för många plattformar. Dettaexamensarbete har undersökt om det är möjligt att designa ett ramverk som förser utvecklaren med ett APIsom fungerar för många plattformar genom att wrappa deras plattformsspecifika kod. Svaret är ja. Ramverketharmoniserar: fjärrkontrollsindata, video, volym, internetförbindelse, TV-kanalströmmar och deras TV-tablåer, till ett gemensamt JavaScript-bibliotek-API. Vidare paketerar ett byggsystem koden på de sätt somplattformarna förväntar sig. Ramverket underlättar utveckling av HTML5-applikationer för TV-plattformar.För tillfället stöder ramverket plattformarna: Pace, PC och Samsung Smart TV, men det kan breddas med flerTV-plattformar.

科技的發展日新月異，數位影音壓縮、網際網路與行動通訊等的技術突破,讓在有線電視、電信網路與行動通訊系統上所能提供相同的服務變的簡單，跨業競爭因此越來越明顯，而數位匯流代表了這個整合的趨勢，然而科技時代進步如此快速，但政府的法令卻遲遲無法跟上時代的潮流演進，因此造成了有線電視產業的封閉與發展停滯不前，甚至造成與電信產業競爭的不公平。 因此本研究的研究目的是探討數位匯流法立法後對有線電視產業的衝擊與因應策略為何?以及新的商業獲利模式為何? 研究方法則是參考Afuah A (2004)經營模式理論為研究架構，先從營運環境的方向來看產業的主要變化因子分別為何，這些因子將如何影響公司，公司又該如何修正自己的定位並調整價值活動、策略資源及成本變化的評估，如此一來才能在這產業快速的變化中維持或創造更高的公司利潤績效。 本研究主張，數位匯流法立法後若在2017年實施分組付費，將會影響有線電視業者的每月營收，同時當頻道上架平台更自由及同業新進業者進入競爭後，有線電視的收視戶將開始出現外流的問題，然而新的立法雖然會產生破壞但也能創造出新的商機，有些新的商機需要雙向網路的機上盒才能達到，因此有線電視業者應全面佈建雙向機上盒同時大幅改善其基礎網路的品質與頻寬，將自己定位為匯流平台並多投入更多的創新應用以拓展新的財源。 / The rapid development of technology breakthrough, like digital video compression, Internet and mobile communications that makes CATV, telecom network and mobile communications operators to provide the same service becomes simple and easy also causing more and more cross-industry competition is obvious. However, it represents the digital convergence intergartion is the trend in the near future. The age of technology advances so quickly, but the government decree has as yet unable to keep up with the trend of the evolution of the times resulting in the CATV industry its the development of stagnation or even resulting an unfair competition with telecommunications industry. Therefore, purpose of this study is to investigate the impact on the cable industry after digital convergence Legislation. 1. What are the CATV operator’s coping strategies? 2. And what their profitable new business model will be? Research method is a reference Afuah A (2004) theory of the business model for the study of architecture, starting with the direction of the major changes in the operating environment in terms of the respective industry factors, these factors will affect how the company, how should revise their position and adjust value activities, resources and strategies to assess changes in cost, this way in order to maintain or create higher profits in the performance of rapid change in this industry. The study argued that the digital convergence Legislation if it is established in 2017 and implement packet charge that will affect the monthly revenue of CATV operators, meanwhile when the channel contents can cross to different platform more freedom and new operators enter the competition. Cable TV subscribers will begin outflow, however, although the new legislation will cause damage but can also create new business opportunities, new business opportunities require to deploy two-way network set-top box to achieve, so the cable companies should be fully provisioned two-way set-top boxes and enchance their infrastructure quality and bandwidth, then positioning itself as a plateform of digital convergence. put more and more innovative applications to expand new sources of income.

日前行政院提出施政報告時指出，將以「挑戰二OO八」作為目標，研議一項為期六年的「國家總體建設計畫」，計畫中又以「兩兆雙星」的產業政策最受矚目，計畫中，數位內容產業是其中一環，希望能在2006年達到三千七百億台幣的產值，增加四萬個以上就業機會﹔經濟部甚至將成立「數位內容學院」，幫助數位產業培養傑出人才，強化國家的競爭力，台灣更訂定2006年為數位電視元年，全面轉換現有類比電視系統，進入數位化電視時代。 所謂「數位電視」時代，泛指數位電視之節目訊號採用數位影音訊號壓縮技術（Digital Video/Audio Compression），透過數位編碼（Digital Coding）與數位調變（Digital Modulation）來傳輸，並具有結合其他數位資料一起廣播之能力。 台灣的無線電視台早在2000 年舉行試播典禮，每天有五小時的數位節目播送﹔五大有線電視多系統經營者，（Multiple System Operator，簡稱MSO），包括東森、和信、台灣寬頻通訊顧問公司、太平洋聯網科技及其他，五大系統商掌控全台將近90%的有線電視收視戶，發展數位電視也最積極﹔衛星電視台如年代，也以衛星直播網路（Direct PC）方式播送數位電視﹔連電信業者如中華電信，更於2000年中成立「互動式多媒體處」，提供用戶互動式影音服務。 本文研究以「創新行銷」、「價值擴散」之理論為主軸，主要探討數位電視相關產業，未來能否成功，或被視聽大眾所接受，本研究之主要目的如下 一、 數位內容與創新擴散模式之關係：不同之數位電視業者，提供哪些不同　　　　　　之數位內容？能吸引哪些消費大眾 二、 數位電視之系統採用與創新擴散模式之關係 三、 數位電視之價格策略用與創新擴散模式之關係 四、 數位電視之使用簡便性與創新擴散模式之關係 本研究以歷史文獻分析法為研究主軸，蒐集國內外相關文獻、書籍、報告、期刊、論文等資料來源加以整理分析，並以國內現有之數位電視業者及其發展之商品，如何進行創新擴散，加以介紹、分析、比較，進而探討出其未來可能之發展與建議。 / The administrative Planning Report passed recently by the Executive Yuan indicates that taking [Challenge 2008] as the target, plan and discuss a 6-year plan, named [National General Construction Planning], and of which the policies for [The Two Trillion, Twin Stars] industry attracts more attention and the digital industry is one of sectors in the planning. We expect the production value would be up to NTD 370 billion in 2006, and increase more than forty thousand job opportunities; even the Ministry of Economy would establish [Digital Institute], for helping educate the outstanding talents in digital industry and sharpen the national competitive edge; and the year of 2006, which was regarded as the Digital Video Year by the Taiwan government, will witness the process of changing the simulating video system into digital video era completely. What is called [Digital Video] era, it is generally referred to the program signal for digital video adopted with Digital Video/Audio Compression technique, and through Digital Coding and Digital Modulation to transmit the message, and has the capability of broadcasting combined by other digital information. Early in 2000, the trying-out broadcasting cerebration of the Radiovision Station in Taiwan was held, and the digital program was broadcasted for five hours everyday; The big five CATV Multiple System Operator (MSO) includes Eastern Television, KG Telecom, Taiwan Broadband Communication Corporation (ANET), Pacific Broadband Company Limited, and others, which control nearly 90% CATV audiences, and develop the Digital Video actively too; The satellite TV station like ERA also broadcasts the digital video by the way of Direct PC; and the communication operator like Chunghwa Telecom established “Interactive Multimedia Office” to provide the interactive video service in 2000. The theory of “Innovative Marketing” and “Value Extending” is taken as the principle in this research, discussing mainly the digital video and interrelated industries, whether it is successful or not, or accepted by the audience. The main proposes as followings: I. The relations between digital and innovative extending; will different digital video operator provide different digital programs? What kind of audience would be attracted? II. The relations between digital video system and innovative extending model III. The relations between the price strategy of digital video and innovative extending model IV. The relations between the convenience of digital video and innovative extending model This research took historic literature analysis as its researching principle, based on the collection and analysis of interrelated literature, book, report, periodical and article etc. information in domestic and oversea, and introduce, analyze and compare how they innovate and extend upon the existing products developed by the digital video operator in domestic, and further discuss its future orientation and suggestion.

台灣有線電視早期因業者惡性競爭，採大量增加頻道、降價促銷方式爭取訂戶，形成獨特的「大碗公」收視文化，民眾支付六百元月租費，即可收看約一百個基本頻道。有線電視頻道雖多，但消費者事實上無力收視，卻仍需為其付費，同時無法選擇符合個人需求的頻道內容。在「大碗公」收視文化下，消費者收視權益難以保障，頻譜無法有效利用則造成社會資源浪費。 近年來消費者意識抬頭，反應希望收看較少的頻道並支付較少費用；為回應消費者擇其所好之收視需求，政府方面提倡實施「分組付費制度」。分組付費制度可落實使用者付費觀念，有助於業者提高市場運作績效、杜絕私接戶，並可保護青少兒收視環境。 過去業者曾經實施分級付費，然而並不成功；其後，政府方面亦提出數種分組付費模式，但截至目前各界仍未達成共識。分組付費立意良善，未能推動實為可惜，因此研究者針對產、官、學進行深度訪談，探討分組付費過去失敗因素、目前面臨問題、各界對分組付費之態度，試圖匯整不同意見，探討分組付費未來可能實施之方式。 研究結果發現，現階段分組付費面臨諸多問題。「大碗公」收視文化使消費者欠缺「使用者付費」精神；加上消費者對於目前有線電視滿意度頗高，推動新制動力不足。此外數位機上盒裝機意願低，亦影響分組付費之推動。業者方面，分組付費將使系統業者收視費之收益降低、購片成本提高；頻道業者廣告收益大幅減少，宣傳行銷成本上升，因此業者反對實施。政府方面認為現階段推動分組付費確有一定困難，但為維護消費者收視權益，未來仍應繼續推動。學者專家則呈現市場開放與加強管制的兩極意見。 雖然分組付費議題目前仍然缺乏共識，但研究者由研究過程中釐清現階段分組付費面臨問題，可供未來研究者針對問題擬定解決方案。研究者亦發現，分組付費並非孤立之政策，其與產業結構、數位化…等議題息息相關，建議未來可由結構面進行探討，同時思考有線電視數位化、相關法規之研議修訂…等議題。此外，為促使有線電視費率合理化，建議相關單位積極輔導其他媒體平台，促成市場公平競爭機制，並擬定具體之數位化政策，提供有線電視業者誘因與獎勵，以較有彈性的角度來思考分組付費問題。 / Because of the serious competition, during early developing time, Taiwan’s CATV system operators provided lots of channels and greatly lowered the CATV price to promote channel services. This promotion strategy has run for years and formed a very unique CATV environment in Taiwan. CATV consumers only have to pay NTD. 600 per month, then they can watch about 100 basic channels nowadays. Although CATV consumers can watch so many channels, they don’t really have so much time watching them all but still have to pay for them. Besides, the CATV bundling price doesn’t allow consumers to choose the channels they really need and want. On the social resource perspective, the CATV bundling pricing strategy keeps CATV channels from being used effectively and brings a waste. In recent years, consumers’ awareness of their rights is getting stronger. Consumers begin to find out the possibilities of paying fewer CATV price and watch fewer channels. In order to respond to the need of consumers, the government advocated CATV channel tiering policy. Channel tiering brings several advantages: consumers can be more active and own more choices; the CATV industry can work more effectively and system operators can prevent those who access CATV services illegally. Also, the advanced technology and hardware of channel tiering can prevent juveniles from watching inappropriate CATV programs. In the past, some CATV system operators tried to implement channel tiering, but it was not successful. The government also advocated several kinds of channel tiering models, but until now, there is still no consensus. CATV channel tiering is basically a good policy for consumers, and it’s a pity that this policy can’t be successfully execute. Therefore, by in-depth interview, the researcher of this study collects opinions from managers of CATV industry, government members and professors to discuss the failure reasons of channel tiering, the problems of execute channel tiering nowadays and different attitude toward this issue. Furthermore, the researcher tries to integrate different opinions to find out possible executive ways of channel tiering in the future. According to the research findings, CATV channel tiering faces many complicated problems now. First, because of the “bowling CATV culture”, Taiwan’s CATV consumers lack for the spirit of “user-payer” principle. Besides, they are pretty satisfied with the CATV services now and have no intention to push a new policy. Furthermore, consumers’ intentions to order digital CATV services and the distribution of DSTB are pretty low, and this situation barriers to the implementation of channel tiering, too. As to the CATV industry, the implementation will affect both CATV systems and channels, so the CATV industry objects to this policy. In order to preserve the rights of consumers, the government members hold that CATV channel tiering policy should execute in the future although it faces many difficulties now. They suggest the government should find an appropriate way and keep pushing this policy. The opinions from professors are very divergent. Some consider that the government should open the CATV market and give the industry more freedom, but some consider that the government should regulate more strictly. Although there is still no consensus on CATV channel tiering, the researcher has some findings during the research process. CATV channel tiering is a very complicated policy which relates to lots of other policies, laws and issues. Therefore, the researcher advices that the channel tiering issue should be considered together with other issues like digital policies, the problems of CATV industry structure and so on. Furthermore, in order to make the CATV service price more reasonable, the government should encourage more medium to provide services equivalent to CATV channel services, give consumers more choices, and build an equally competitive market. To summarize, the research advices that channel tiering issue is not a single policy and we should rethink it in a more flexible way.

An IP based set-top box (STB) is essentially a lightweight computer used to receive video over the Internet and convert it to analog or digital signals understood by the television. During this transformation from a digital image to an analog video signal many different types of distortions can occur. Some of these distortions will affect the image quality in a negative way. If these distortions could be measured they might be corrected and give the system a better image quality. This thesis is a continuation of two previous theses where a custom hardware for sampling analog component video signals was created. A software used to communicatewith the sampling hardware and perform several different measurementson the samples collected has been created in this thesis. The analog video signal quality measurement system has been compared to a similar commercial product and it was found that all except two measurement methods gave very good results. The remaining two measurement methods gave acceptable result. However the differences might be due to differences in implementation. The most important thing for the measurement system is to have consistency. If a system has consistency then any changes leading to worse videoquality can be found.

有鑑於台灣將於2006 年全面轉換現有類比電視系統，進入數位 電視時代，此趨勢亦將帶動數位電視未來的成長與發展，但基於台灣 數位視訊服務與接收設備產品正處於起飛的階段，未來發展的不確定 性仍高，因此其市場商機與未來技術之發展就非常值得進行研究與探 討。故本研究藉由SRI 情境預測法，對台灣未來5 至10 年的有線數 位機上盒(Digital Cable STB)的功能、技術需求與市場狀況做分析預 測，並針對可能發生的情境，提出因應策略，以提供有線數位式機上 盒供應商做未來策略決策時的參考。 本研究係透過包含學界及實務界的專家群會議輔以腦力激盪的 方式循序討論出關鍵決定因素與驅動力量，並以三個不確定軸面形成 情境主軸，發展擴充成為情境內涵，再就各選定之情境(風雲年代、 市場導引、技術革命及夕陽餘暉)內容進行SWOT 及策略發展分析， 並發展出有線數位STB 供應商之市場及技術共通發展策略： 在市場發展策略方面，建議台灣數位有線STB 供應商考慮： 1.形成同業默契，避免掀起價格戰，維持合理利潤。 2.為避免分散力量，造成惡性競爭。應尋求同、異業結盟，擴大業務 規模及市場佔有率，並提高對供應商的議價力量。 3.與TV 業者結盟，推廣HDTV 市場。 4.取得主要CA 供應商授權，共同開發高成長潛力市場。 5.與MSO 業者結盟，合力推動數位視訊市場發展。 在技術發展策略方面，則建議應考量： 1.核心技術之提昇，如CA，寬頻通訊及HDTV 技術。 2.多功能STB 之開發，如DVD, Home Theater, Cable Modem, VoIP 及PVR 等。 3.與台灣半導體業者合作開發關鍵零組件(IC)以降低成本並掌握關鍵 技術。 4.Open Cable 之開發，以因應不同CA 系統之需求。 5.XDSL STB 與無線寬頻技術之研究。 / Taiwan government has formally announced to switch to digital TV program broadcasting from present analog TV program broadcasting system starting year of 2006.
