In 2005–2006 the research group DRACE (Digital Radio Cultures in Europe) performed a study on how 43 people in key positions related to the radio industry in 4 European countries and Canada viewed the future of radio and which delivery technologies they considered would be most successful. In addition, it analyzed the motives and reasons certain technologies were seen as more promising than others. Finally, it presented 4 different future scenarios for radio media. The study was published in the Journal of Radio and Audio Media, May 2008.
In 2005 the future of radio was considered much less obvious and clear than it appeared 10 years previously. Instead of a transition from analog to digital audio broad- casting (DAB), there was a selection of alternative technological options for digital audio delivery. When looking back from 2015 and considering the results of expert interviews, the project group about Public Service Media in the HERA project: Transnational Radio Encounters found interesting perspectives in replicating this study—now looking forward to 2025. By using the same questionnaire and interviewing the same experts (or new persons in the same positions) they could compare the predictions with the present situation, looking for technological, regulatory, policy based, and user-oriented contexts. Furthermore, they could ask the experts to look 10 years forward to 2025. Besides from the interviews, desk studies were performed in order to explore the national similarities and differences as background for the analysis of the scenarios for the 2015 and 2025 studies.
This comparative study involves Denmark, Finland, Germany, Ireland, and the UK. 相似文献

Digital radio policy in Canada has moved from a position of seeking to migrate all radio broadcasting onto a single digital transmission system (Eureka-147) to a multi-platform, cross-media and multimedia approach. The most recent digital radio policy of 2006 suggests a range of new possibilities for radio broadcasting, including multimedia broadcasting, but as a result has compromised the early adoption of the Eureka-147 standard. This paper contrasts the different policy contexts of 1995 and 2006 and argues that the competing technological options for digital audio delivery now pose significant dilemmas for broadcasters and policy makers. 相似文献

A decade ago the regional programming of CBC Toronto successfully transformed itself with a new notion of community reflection that utilized a range of emerging digital platforms but put narrative radio storytelling at its centre. With the launch of CBC Hamilton in Spring 2012, as Canada's sole digital-only public broadcasting outlet (no over-the-air TV or radio), audio storytelling was conspicuously absent from the equation. Based on the only publicly available research conducted with CBC users and community leaders prior to and following both launches, the authors raise questions about audience conceptions and the enduring value of audio storytelling in an era of digital broadcasting and social media. 相似文献

Digital radio- which encompasses digital production and digital distribution (via broadcasting and the Internet)-is being marketed in the UK and Europe as a set of technologies that will enhance public choice, democratic participation, and interactivity. An analysis of it from a political-economic perspective, however, suggests that in a loosely regulated market economy, digitalization will not necessarily significantly increase choice or participation: On the contrary it is likely to encourage further concentration of ownership in the radio industry, thus restricting diversity. It may also risk exposing radio to structural subordination to other mass media. The article draws on trade and specialist reports as well as broader theoretical perspectives to support its central claims. 相似文献

The physical remnants of long-lost radio programs are not the only sounds that broadcast historians must unearth to unravel the mysteries of radio production and reception. In this essay, I examine the audio tapes of a 1980 oral history interview of Isabel Baumann, a Wisconsin farm wife, rural activist, and radio personality who appeared for twenty years on a monthly local radio show called The We Say What We Think Club. I tell the story of how these recordings came to be archived at the State Historical Society of Wisconsin and the unique institutional context that preserved Baumann’s voice for future generations. The tapes of Baumann’s recollections of her farm life and radio career offer us not only one of the few examples of the sound of Baumann’s voice, but gives insight into how the very process of making oral histories helped her (and ultimately, us) understand the power of her radio work. Oral histories offer a space for women, so often marginalized in the industry and in historical narratives, to say what they think. Most importantly, the audio recovered from these academic projects allow historians to record with more fidelity what these women thought. 相似文献

To a certain extent, the position of radio in Botswana since the colonial period has benefited significantly from recent developments in the media. The potency of radio as a mobile medium; its usefulness for public dialogue and entertainment; and its effectiveness as a less sophisticated technology that is easily accessible and adaptable in remote communities, have ensured that radio remains the most preferred and dominant medium of mass communication in Botswana. The recent introduction of the Internet and digital communication technologies also meant that in Botswana, radio is appropriately situated in the World Wide Web and mobile phones. 相似文献

As digital radio broadcasting enters its third decade of operation, few would argue that it has met all expectations expressed at the time of its launch in the mid-1990s. Observers are now more circumspect, with views divided on the pace of transition to an all-digital future. In exploring this mismatch between expectation and actuality, this article considers the introduction of FM radio in the 1950s. It too was expected to replace its forebear (AM) but, like digital radio, its adoption by listeners was slower than anticipated. An examination of published literature, in particular engineering and technical documents, reveals a number of similarities in the development of digital radio and FM. Assumptions about listeners’ needs and preferences appear to have been based on little actual audience research and, with continual reference in the literature to the supposed deficiencies of the predecessor technology, suggest an emphasis in decision making on the technical qualities of radio broadcasting over an appreciation of actual audience preferences. 相似文献

This essay explores the diverse field of audio records manufactured as tie-ins to popular American radio programs of the postwar period. Little has been written on such products as meaningful artifacts of consumption during any phase in broadcasting history. Yet radio records proved especially meaningful to customers in the 1940s and 1950s, as they offered a highly convenient way to upend rigid transmission schedules and program ephemerality. Here, I focus on spoken word radio albums that promised listeners important broadcast knowledge stored for ‘posterity’ on disk. Phonograph companies like Columbia banked on consumer interest in replay of these programs to sell radio records as technologies of permanence and documents with unparalleled historical and cultural value. I analyze program-to-record case studies like You Are There (1949) and The Quick and the Dead (1951) to illustrate how producers lay claim to historical authenticity via capturing, recording, or releasing transient moments on records. 相似文献

We are living in turbulent times, with the threats of COVID-19 and related social conflicts. Digital transformation is not an option but a necessity for governments to respond to these crises. It has become imperative for governments worldwide to enhance their capacity to strategically use emerging digital technologies and develop innovative digital public services to confront and overcome the pandemic. With the rapid development of digital technologies, digital government transformation (DGT) has been legitimated in response to the pandemic, contributing to innovative efficacy, but it also has created a set of challenges, dilemmas, paradoxes, and ambiguities. This special issue’s primary motive is to comprehensively discuss the promises and challenges DGT presents. It focuses on the nature of the problems and the dilemmatic situation in which to use the technologies. Furthermore, it covers government capacity and policy implications for managerial and institutional reforms to respond to the threats and the uncertainty caused by disruptive digitalization in many countries. To stimulate discussion of the theme of this special issue, this editorial note provides an overview of previous literature on DGT as a controlling measure of the pandemic and the future direction of research and practice on DGT. 相似文献

In the last two decades, the University of Colima has worked out a very interesting project for information technologies development through its Coordination for Information Technologies (CIT) program. This has provided years of experience in the application of technologies for the academic community. After its designation as a UNESCO Regional Center, our university developed a very ambitious education and research plan that was submitted to one of UNESCO's educational programs. This project was approved as the “UNESCO Chair on New Information Technologies,” and it started working successfully with the “Diploma Course on Digital Libraries” 2 years ago.The Diploma Course is part of the action taken toward the creation of a Great Iberoamerican and the Caribbean Digital Library. Today 144 trainers from 36 national libraries in Latin America and the Caribbean state members are receiving training courses based on the UNESCO methodology, which is comprised of the registration of digital objects, adherence to standards for audio and video digitization, and development of an international open-source software for information management. 相似文献

ABSTRACT In the 1990s, electronic reserves services rapidly developed in academic libraries following the emergence of the Internet, particularly the World Wide Web, as an information delivery tool. Because similar technologies are used to develop and access digital libraries and electronic reserves, the implications for the evaluation of electronic reserves go beyond traditional service satisfaction levels. User responses to electronic reserves are an indicator of the acceptance and technical challenges of digital libraries. As we examine user reactions, inferences can be made on such topics as user technical skills, institutional networking infrastructure and the electronic communication process in instruction. These inferences give us greater insights into the future use, satisfaction level and technical demands in the use of digital libraries. 相似文献
