數位視訊地面廣播(Digital Video Broadcasting-Terrestrial)標準化的意涵及其在台灣轉換實踐之研究 / A study on implication of digital video broadcasting-terrestrial standardization and its implementation in Taiwan

張雪玉, Liu, Shirley Unknown Date (has links)
2001年5月交通部電信總局決定,我國數位電視地面傳輸標準以往訂定為美規ATSC系統,但由於科技不斷進步,電總將採技術中立,由業者自行決定採用歐規DVB-T或美規。技術的意見未受到政治干預而予實踐,在台灣政策科學發展過程中,係一重要的案例。 就歐規的整體發展來看,傳統無線電視產業的垂直整合,已逐漸被數位無線電視產業的垂直分工及水平整合趨勢所取代,台灣從垂直壟斷系統電視體制轉移至水平整合垂直分割,如此標準化的轉移自有其意義。本研究以DVB的歷史來源脈絡導入作為分析的起點,探討台灣從美規轉換為歐規所帶來產業革新的意義,及導引政策的落實。 南韓在政府的強力主導下,其數位無線電視的規格採用美規ATSC,但是行動接收則開放給了歐規,其數位電視規格消長過程和台灣極為類似,係一比較性研究之對象。 2003年及2006年台灣公視基金受新聞局委託,建置第二單頻網傳輸系統,準備建立製播分離與共同傳輸平台機制的公共政策,公共廣電媒體身處於多媒體、多頻道競爭的生態環境中,面對數位科技的挑戰,亦有其角色定位的變化。 依據本研究的理論架構,台灣的標準化模式係已轉移為在地特有的樣貌。 台灣實踐歐規標準除了目前15個數位電視台產業的發展,還導引出公共政策的決策,公共電視台扮演「機制黏著劑」的功能,建立參與者之間的共識基礎,最後形成相關的產業政策,其顯示的意義係由市民社會為了共同的理念建立往上推的範例。由DVB-T政策的制定,導引出這些現象觀察,DVB-T確有改革的意義。 / May 2001 Directorate General of Telecommunications, Ministry of Transportation and Communications made a bottom-up decision due to consecutive development of science and technology. The Directorate General took a neutral stand to let digital TV enterprises select freely whether they preferred still attached to the existed ATSC or switched to DVB-T once their standards needed to be adopted. Such a new technical idea, not only without meddling by political forces, but also smoothly put into practice, indeed became an important case in the evolving communications policies in Taiwan. From the viewpoint of general development of DVB, the vertical integration of the traditional broadcast industry has been gradually replaced by the horizontal integration of video broadcast industry. In Taiwan, the transfer of standardizations from ATSC to DVB-T has its own significance. This study began with the analysis of the origin of DVB as research guidelines, in order to comprehend the significance of industrial innovations in the transferring from ATSC to DVB-T, and understand what policy concern been put into practice. Complied with the clear state’s guidance, South Korea’s digital TV adopted ATSC, however its mobile application adopted T-DMB. The similarity of digital TV adoption between Taiwan and South Korea turned out to be a typical subject for comparative study. In both 2003 and 2006 Government Information Office entrusted Taiwan Public TV a fund to conduct single frequency network in preparation for establishing a transmission platform. Competing with the multi-media and multi-channel business and facing the challenge of digitization, public service broadcasting is entitled to many different roles it plays during transition. Based on the framework of this study, the DTV standardization in Taiwan obviously belongs to a local version of its globalization. In practice, DVB-T in Taiwan has not only been applied by five terrestrial broadcasters, but also brought the concept of DVB into practice. Public TV, functioning its “institutional glue”, reached a consensus among participants, and eventually facilitated concerned industrial policies been set up, which indeed indicating a multilayer of civilian forces were grouped together through a bottom-up decision model. All those observations of policy decision and its application have certainly generated from the adoption of DVB-T.

"Vart är vi på väg?" : En kvalitativ studie av Sverigedemokraternas vision för public service, och dess förhållande till politik, juridik och teori

Strömberg, Viktor January 2020 (has links)
Den eviga debatten kring public service roll i svensk demokrati har under vintern blossat upp rejält på nytt i och med Sverigedemokraternas utspel om att kalla in bolagens chefer till Kulturutskottet och Linus Bylunds uttalanden om att straffa partiska och osakliga journalister. Denna studie syftar till att utröna vad Sverigedemokraternas vision för public service är och hur den förhåller sig till övriga politiska partier, det förvaltningsrättsliga systemet och normativa teorier om medier. Studien undersöker detta genom en kvalitativ textanalys som inledningsvis fokuserar på Sverigedemokraternas vision av public service för att därefter även gå vidare och undersöka public service ur de tre andra perspektiven i syfte att ta reda ta reda på hur Sverigedemokraternas vision förhåller sig till dessa. Analysen ger för handen att den Sverigedemokratiska visionen – i komprimerat format – handlar om ett public service-bolag som i grunden behövs för att fylla viktiga funktioner i termer av demokrati och samhällsnytta som marknaden inte kan tillhandahålla. Bolaget ska ha ett grundläggande samhällsuppdrag och ett brett kulturuppdrag med storslagna svenska dramaproduktioner. Bolaget ska ha ett högt förtroende bland allmänheten, vara underställd omfattande granskning och bedriva ett extensivt nordiskt samarbete. Till en av de mest intressanta kontrasterna som uppstår kan nämnas hur det hos Sverigedemokraternas ledamot i förvaltningsstiftelsen, Linus Bylund, går att se likheter med det normativa sovjet-kommunistiska perspektivet. Det framgår även att Bylund konsekvent ger uttryck för en mer radikal och kollektivistisk linje jämfört med partiet. Detta är något som väcker stora frågor kring huruvida detta är att anse som en mer oslipad version av partiets syn på public service eller om Bylund driver public service i en egen riktning. / The perpetual debate concerning the role of public service broadcasting in Sweden has once again resurfaced. This time as a result of the Sweden Democrat’s request to summon the directors of the public service companies to the Parliament’s Committee on Cultural Affairs and Linus Bylund’s comments about punishing biased and unobjective journalists. The aim of this study is to examine the Sweden Democrat’s vision for public service broadcasting and how it relates to other political parties, administrative law and normative theory. The study examines this by a qualitative analysis of a wide range of documents including parliamentary bills, broadcasting licenses and academic literature containing normative media theories. The analysis shows that the Sweden Democrat’s vision – in summary – is about a public service company needed for fulfilling important functions in terms of democracy and public welfare that the private market is not capable of providing. The company shall have a basic societal mission and a wide cultural mission with grand productions of Swedish drama. The company shall have high trust among the public, be under comprehensive scrutiny and conduct an extensive Nordic cooperation. One of the most interesting findings when comparing the different perspectives is the similarities between Linus Bylund, who is the Sweden Democrats commissioner in the foundation that owns the public service companies, and the normative Sovjet-communist perspective. It is also apparent that Bylund seems to be constituting a more radical and collectivistic view compared to the party. This raises questions as to whether this is a cruder version of the party’s view or if Bylund is moving Swedish public service broadcasting in a direction of his own.

Public Service – at your service? : A study of attitudes toward the public service broadcasting company SVT

Mikkelsen Båge, Else January 2022 (has links)
Public service broadcasting is a longstanding broadcasting institution in Sweden. Being the most consumed and highly trusted media broadcasting institution on the market, it suffers both challenges and acclaim. It has become a highly politized matter. For the first time since its founding, trust and attitudes towards the public service broadcasting companies are starting to slowly dwindle and are being questioned. Representatives from parliament parties are calling for abolishment and restructuring, and the consumers are abandoning the public service broadcasting channels for commercial competitors. This is especially noticeable amongst youth. The aim of the study is to identify and analyse what factors can be relevant for understanding attitudes towards public service broadcasting. With a theoretical background in Markus Prior’s post-broadcast democracy, James G. Webster and Thomas B. Ksiazek’s audience fragmentation theory, and Strömbäck’s definition of media trust, a theoretical framework regarding consumption and factors concerning attitudes was constructed. Through this, the value of a public service broadcasting system could be charted, and consumer attitudes be understood.   The study consists of data from a nationwide survey. The data was analysed with binary logistic regression analysis, performed on two samples, one representing the Swedish population at large, and one representing youth. This to observe whether or not there were any differences between what factors constitute trust and positive attitudes towards public service broadcasting. Main findings include that youth is much less politically polarised than the population at large. Factors such as education, gender, and regularly consuming public service broadcasting content were also shown to be significant for attitude formation. From this, I could derive that the Swedish population, despite increased polarisation, still has very high levels of trust in, and positive sentiments towards the public service broadcasting company SVT.

Česká televize a Český rozhlas optikou modelu PSM: případová studie / Czech television and czech radio in the perspective of the PSM model: a case study

Obrovský, Petr January 2013 (has links)
The master thesis describes the development of Czech Television and Czech Radio be- tween 2005 and 2012, focusing on media policy, technology, content and attitude to the audience. It applies research output of the RIPE initiative as a theoretical basis for col- lection and interpretation of the data. RIPE, which links academia with media profes- sionals worldwide, aiming to redefine the public service remit for the 21st century, sug- gests that the political, economic, technological and social context has fundamentally changed in the last two or three decades. As a result, the original concept of public ser- vice broadcasting, established in Western Europe after the Second World War, has lost its legitimacy. It is therefore necessary for public service broadcasters (PSB) to trans- form into public service media (PSM). This means diversifying modes of distribution to new technologies besides traditional broadcasting, setting mechanisms of two-way and interactive communication with the audience, producing multimedia content exploitable on various platforms and clearly defining and justifying the value added of their offer- ings compared to those of commercial competitors. Using the method of case study, the thesis matches this conceptual framework with the situation in Czech Television and Czech...

Veřejná služba v ČR: naplňování úkolu veřejné služby na příkladu České televize / Public Service Broadcasting in the Czech Republic: compliance with PSB criteria in the case of the Czech Television

Douděrová, Lucie January 2016 (has links)
The thesis Public Service Broadcasting in the Czech Republic: compliance with PSB criteria in the case of the Czech Television is covering the topic of public service media and their system of public service evaluation. In its theoretical part this thesis is describing several approaches to a definition of public service media themselves. It is also mentioning history of the concept itself and its development not only in the Czech Republic but in Great Britain as well as other European countries. The practical functioning of the public service evaluation system is also covered on an example of the BBC and the Czech Television. In the analytical part the author is trying to describe and sum up the evaluation system as it is used by the Council of Czech Television. Detailed analysis of the data and its sources is provided as well as identification of elements that are taken into the consideration when evaluating. The analysis then leads to a discovery of certain discrepancies in the evaluation process and its outcomes. The author is trying to identify the most problematic points of the system.

Digital dilemmas: the Australian Broadcasting Corporation and interactive multimedia publishing, 1992 – 2002

Martin, Fiona R Unknown Date (has links)
From the 1990s onwards the Australian Broadcasting Corporation (ABC) adopted a range of interactive multimedia activities: CD-ROM, web publishing, datacasting and interactive television. Drawing on extensive primary research, this thesis explores why the ABC pursued an interactive multimedia program under a neo-liberal rationality and how online publishing in particular has impacted on its role as a public service broadcaster. Drawing on neo-Foucauldian governmentality theory and Scott Lash’s critique of information, the thesis examines how the ABC operates as a technology of government in the transition to an informational society. While it considers the ABC as a localised, specific form of public service broadcasting, many of the findings have importance for analysis within the broader field of state intervention in media markets. It demonstrates that networked interactive multimedia are a communications strategy appropriate to the governance of a globally implicated market-state during a period of informationalisation – characterised by increased symbolic flows, spatial and temporal compression, decontextualised and disorderly relations of information. Public service media will transition this period, characterised by rapid social change and institutional upheaval, where they can incorporate and exploit the informational relations that threaten to diminish their utility as governmental assemblage. It finds that while ABC executives used technological change to adapt to the enterprise focus of neo-liberal government, the corporation was simultaneously transformed by disorganisational influences pursuing an ethics of internetworking. Contrary to Lash’s ideal schema of institutional decline, disorganisation – embodied in the ad hoc, program-maker led push for internet access and publishing – can become a force for organisational renewal. This is observable in the development of ABC Online, a public access web service. The conclusion drawn from ABC Online’s emergence is that the era of digitalisation exposes the ABC as a mutable object, a flexible strategy of national communications governance. It is not exclusively tied to a technical system, such as radio or television, or a practice such as broadcasting. Interactive multimedia such as ABC Online may help the ABC to readdress its contradictory political rationale – the call to represent a coherent national identity in the face of infinite lived diversity – and play a new role in connecting and engaging its users.This thesis re-examines that role in light of Lash’s observations about the nature of informational power. It explores at length the response to a new self-governing, performative subject, the user of interactive multimedia technology. The user, unlike the audience, is visible, often vocal and social. She negotiates both the space of a multimedia object and dialogic interactions within that space. Her exemplary expertise may rival that of the ABC’s program-makers. This analysis indicates that in response to informational phenomena, the ABC has reconceived its space of government, its pedagogy and its production of citizenship in order to remain an effective expression of governmentality. An online ABC may act as a mediatory, contextualising strategy that helps users negotiate the construction and function of difference. It may also be altered by user knowledge. These relations are possible, although preliminary in this research, while the ABC remains wedded to the more disciplinary relations of broadcasting. The implication is that a digitally networked ABC should not be a self-enclosed institution. It is part of an informational network: a multi-sector innovation system. It should not be divorced from its public or the market except in its ethics of exchange. It is a technology that through its technocultural relations socialises, is shaped by and melds with its sometimes unruly user/citizens. It influences, is influenced by and is part of a volatile mediascape. The ABC is organisation and disorganisation, the rigidity of the one generating the other and then being reincorporated, in a cycle of institutional and industrial change.

做為新制度流派之一的歷史制度論認為:一政策的成形,乃為情境中各要角(actor)勢力的競逐過程。研究者則在探討,做為競逐場域的共同傳輸公司,各要角勢力的競逐態勢,又將對未來台灣數位無線電視的樣貌,產生什麼樣的影響? 本研究提出,要探討台灣共同傳輸公司的建構意涵,需回到歐洲公共廣電媒體數位化的發展脈絡進行考察,並再回到台灣的情境脈絡中,定義共同傳輸公司於台灣的建置意涵為何。 研究者從八國(英國、瑞典、西班牙、法國、荷蘭、芬蘭、愛爾蘭、義大利)歐洲公共廣電媒體數位化的過程,歸納出三套共同傳輸公司的類型,包括:「既有獨佔型」、「準公共事業型」,及「市場競爭型」。本研究除分析這三種傳輸公司類型移植台灣的意義為何,並進一步評估其移植的可行性。另外,本研究亦針對共同傳輸公司議題,對未來「NCC作用法」的修法方向提出建議。 / The goal of Historical Institutionalism is one of the sects of New Institutionalism. It focus on finding, measuring and tracing patterns and sequences of social, political, economic behavior and change across time and space. Historical Institutionalism argue that the actors involved in the social context are the important variables for understanding political outcomes. This study try to find out the process of transmission company construction in Taiwan based on the viewpoint of historical institutionalism. Taiwan government plans to switch of the analog terrestrial television before 2010. Government try to stop the vertical integration of terrestrial television. Then also plan to construct the transmission company. This study compares with the process of digitalization of European public service broadcasting, and typologies 3 forms of transmission company, including ‘Existing-monopoly Type’, ‘Quasi-public service Type’ and ‘Market-competition Type’. After that, continuing thinking about the adaptability of three types in Taiwan. And also interprets the connotation of development of transmission company in Taiwan.

Média a edukace (na materiálu vybraných domácích a zahraničních výzkumů mediálních edukačních obsahů) / Media and Education (based on the material of the selected domestic and foreign surveys of the media educational contents)

Landová, Marína January 2012 (has links)
This dissertation deals with the problematics of the research of the educative media content, using mainly the data we gathered during surveys carried out between 2003 and 2011. The paper handles several theoretical and methodological aspects of the relationship between media and education, namely the role of educative media in education as such. In the theoretical part we focus mainly on the interdisciplinarity of the subject, i.e. the differences in the media studies and other social sciences perspectives. After a description of the necessary theoretical/methodological framework, an outline of a classification system of educative programmes is proposed that could be useful both in pedagogical and media practise. In the next part of the paper we discuss the current state of the czech public service media education area. The second chapter itself consists of selected researches results carried out in the area of education programmes and contents, some of which the author of this paper collaborated on. The survey choice consisted of questionnaire and enquiry surveys focusing on the relationship of structured media audiences (students and teachers) towards educative programmes. The other survey then aimed at selected educative programmes, using both content analyses and focus groups as tools to...
