Dissertations / Theses on the topic 'Radio broadcasting, management'

In recent years, there has been tremendous growth in digital multimedia technologies, from voice to data to video, and the recent, but growing, demand of supporting diverse quality of service (QoS) guarantees. It places new demands for future wireless networks in utilising the available radio resource in a more efficient and effective way. The key to this demand is the involvement of efficient radio resource management (RRM), to provide various QoS support for multimedia service delivery. Due to the unique broadcast nature and ubiquitous coverage of satellite communication system, the synergy between satellite networks and terrestrial networks provides new opportunities for delivering point-to-multipoint (or one-to-many) multimedia content to a large audience spread over extensive geographical area. It is expected that the satellite component will play a complementary, but essential, role in delivering multimedia data to those areas where the terrestrial high-bandwidth communication infrastructures are, either economically or technically, unreachable. The emphasis throughout this research is on the potential optimization techniques pertinent to the RRM to facilitate multimedia broadcast/multicast service (MBMS) delivery over the satellite digital multimedia broadcasting (SDMB) system, which has emerged as one of the most promising approaches for this mission. We concentrate on the algorithm development and performance evaluation of RRM strategies implemented at the radio access layer in the SDMB system, aimed at the efficient delivery of multimedia applications to mobile users at satisfactory QoS. Firstly, we have developed a novel two-level channel multiplexing scheme for the radio resource allocation (RRA), which is capable of optimally performing both logical and transport channel multiplexing via two new optimization algorithms, namely optimum estimation algorithm (OEA) and power-oriented adaptation (POA) algorithm. Simulation results prove that the proposed scheme can effectively improve the performance in terms of channel utilisation, power consumption as well as transmission capacity. Secondly, we have investigated the optimization of packet scheduling algorithms via the various adaptations of a proportional differentiation model. By taking into account multiple performance measures, e.g., buffer occupancy, queuing delay and data rate, several novel algorithms, i.e. buffer-length related queue (BLRQ), delay differentiation queue (DDQ) and combined delay and rate differentiation (CDRD), are introduced for performing the packet scheduling task in SDMB. Their performance has been evaluated via simulation means and compared with existing schemes. It is demonstrated that the proposed proportional differentiation packet scheduling schemes can achieve significant performance improvements in queuing delay, jitter and channel utilisation. Finally, we further optimize the packet scheduling schemes by using cross-layer design and adaptive optimization mechanisms. Cross-layer joint priority queue (CJPQ) and adaptive multidimensional QoS-based (AMQ) packet scheduling algorithms are introduced within this context and investigated via simulations. It is shown that these proposals can significantly improve the QoS performance amongst heterogeneous competing flows in terms of both scheduling efficiency and fairness, offering better flexibility and scalability features.

This study tested the job satisfaction of major market radio station general managers in the aftermath of deregulation. The study consisted of two phases, a quantitative, anonymous, mail survey utilizing the nationally recognized Job Descriptive Index (JDI); and a qualitative follow-up telephone interview. Of 246 general managers solicited, 144 returned usable JDI surveys. The JDI consisted of six separate scales, each measuring satisfaction on a different aspect of the job. The followup telephone interview comprised seven questions designed specifically to explore the effects of broadcast deregulation on the respondents. Two hypotheses were tested. The hypotheses tested for differences in job satisfaction scores between radio station general managers and the normative scores of individuals of similar education and job tenure in other industries. In most of the subscales tested there was no significant difference between the two groups. The qualitative telephone survey found widespread dissatisfaction with the effects of deregulation on the broadcast medium.

ENGLISH ABSTRACT: Community radio stations in South Africa are faced with a huge challenge to become sustainable in the process of serving their communities. The issue of sustainability itself is complex and shaped by a range of conditionalities. These include community participation, funding, regulatory and licencing factors, staff and management expertise, and the strategic planning and management capacity of a station. Often the communities themselves are materially poor and unable to contribute in monetary terms to the radio station. However, these same communities are also a source of wealth when it comes to experience, ideas, human power and time. A major challenge is for station management to develop organisational strategies that facilitate full utilisation of this community resource in the process of sustaining their stations. The focus of this study is on two stations in the Western Cape - Bush Radio and Radio Zibonele - and how their management is responding to the challenge of sustainability. Bush Radio has evolved a diversification strategy based on providing formal training and development as an income-generator, and Radio Zibonele has responded through a strategy of selling airtime to advertisers. This work describes these sustainability strategies and explores whether they constitute 'building a brick column or a brick wall'. The conclusion suggests that while both radio stations demonstrate varying degrees of community participation, clear internal systems of monitoring and control of resources, they differ in some fundamental respects of strategy. Bush Radio, on the one hand, shows a clear commitment to consciously diversifying income sources in a way that does not leave the station highly dependent on any single source. This, the writer submits, constitutes an attempt at building a "brick wall". Radio Zibonele, on the other hand, shows a clear commitment to consolidation and reliance on advertising revenue as a single source of income for the station. To the extent that this station relies on a single source of income and does not demonstrate any strategic objective of diversifying sources, the writer submits, it is building a "brick column". The basic assumption of this study is that while the challenge of sustainability constitutes an objective reality facing community radio stations in South Africa today, the subjective responses developed by station management to deal with this challenge can and often do make a difference.
AFRIKAANSE OPSOMMING: Gemeenskapsradiostasies in Suid-Afrika staan voor 'n groot uitdaging om volhoubaar te ontwikkel. Volhoubaarheid as sulks is kompleks en word deur 'n verskeidenheid faktore beinvloed. Dit sluit in gemeenskapsdeelname, befondsing, regulerings- en lisensierinqsfaktore, personeel- en bestuursvernuf en die strategiese beplanning en bestuurskapasiteit van die stasie. Meestal is die gemeenskappe self arm en nie daartoe in staat om in rnonetere terme 'n bydrae tot die stasie te lewer nie. Dieselfde gemeenskappe is egter ook 'n bron van rykdom in terme van ondervinding, idees, mannekrag en tyd. Een van 'n stasiebestuur se grootste uitdagings is om organisatoriese strateqiee te ontwikkel wat die volle gebruik van die gemeenskapshulpbron sal fasiliteer in die proses om hul stasies volhoubaar te ontwikkel. Die fokus van die studie val op twee stasies in die Wes-Kaap - Bush Radio en Radio Zibonele - en hoe hul bestuur op die uitdaging van volhoubare ontwikkeling reageer. Bush Radio het 'n diversifiseringstrategie ontwikkel wat op formele onderig en ontwikkeling as 'n inkomstegenereerder gebaseer is. Radio Zibonele, daarenteen, konsentreer op adverteerders. Die werk beskryf die volhoubaarheidstrategiee elk van die radiostasies. Die gevolgtrekking word gemaak dat albei radiostasies wei verskillende grade van gemeenskapsbetrokkenheid, duidelike interne monitorsisteme en beheer van hulpbronne het. Tog verskil hulle ten opsigte van sekere fundamentele strategiee. Aan die een kant het Bush Radio 'n duidelike verbintenis tot 'n bewustelike diversifisering van inkomste op so 'n manier dat die stasie nie afhanklik is van een bron van inkomste nie. Die skrywer vergelyk dit met die bou van 'n "baksteenmuur". Radio Zibonele, aan die ander kant, is verbind tot advertensies as die enigste bron van inkomste. Aangesien die stasie op 'n enkele bron van inkomste vertrou en nie enige strategiese doelwitle vir die diversifisering van hulpbronne het nie, vergelyk die skrywer dit met die bou van 'n "baksteenpilaar" . Die basiese veronderstelling van die studie is dat die reaksie van die stasiebestuur In deurslaggerwende verskil kan maak om die uitdaging van volhoubare ontwikkeling Suid- Afrikaanse radiostasies die hoof te bied.

In the South African (SA) model of community radio, listeners are expected to be in charge of the management and programming operations of stations. This study tests the SA model against the actual conditions at an existing station. For this purpose, the study focuses on Radio Graaff-Reinet, a community radio station in the Eastern Cape. Emphasis is on examining the extent to which members of the station’s target community are involved in its operations. The study first assesses the nature of this involvement, keeping in mind the principles of, ‘community ownership’ and ‘participatory programming’ on which the SA model of community radio is based. It is argued that the station does provide a valuable ‘public sphere’ for its listeners. The potential of this sphere remains limited, however, due to the impact of ongoing power struggles around the ownership of the station. The lack of proper systems for managing these struggles has contributed to the fact that the station continues to be in a constant state of flux, with a high turnover of staff and regular changes in its policies and strategies. The study argues that, until such systems are put in place, the principles of community ownership will not be fully realizable. Areas in which the struggle over ownership plays itself out can be identified in the relationship between the station’s Board of Directors and its managing staff, between one particular station manager and her staff and between the station and its target community. These struggles often take place in context of a debate about the financial sustainability of the station versus its developmental aims. It is argued that this opposition needs to be questioned since, until the station is financially stable, it will remain vulnerable to interference by powerful individuals and groups in its attempts to establish such developmental aims. The study then goes on to identify key weaknesses in the station’s approach to community ownership and participation. In particular, it is pointed out that various stakeholders in the station have contradictory understandings of what is meant by ‘community’, using the term to include or exclude sections of the Graaff-Reinet society in very different ways. There are also very different understandings at play about the concept of community radio itself. These contradictions have an impact on the station’s ability to implement participatory programming. This situation is exacerbated by the fact that the station does not have a consistent forum in which shared decision-making can take place. Consequently, the station also remains unable to draw effectively on its own volunteer staff and on its community as resources for programming content. Finally, the study explores the broader significance of the weaknesses that exist in the case of Graaff-Reinet, arguing that these are problems that repeat themselves throughout the South African community radio sector. Possible strategies for addressing these problems are suggested, including approaches to monitoring and research, training, organizational development and advocacy.

The state of the environment is increasingly present as an urgent concern for contemporary political, social, cultural and physical life. Yet the roles of the mass media (radio, television and newspapers) in shaping and influencing crucial public awareness, debates and environmental decision-making remain inadequately understood. Positioned as a critical studies inquiry into media representations and audience reception, this study forms part of a wider project amongst media scholars and culture critics on the relationship between media textual production and consumption. It explores how one radio station in Uganda, Central Broadcasting Service (CBS) radio, represents and constructs the environmental crises faced by Lake Victoria, especially pollution and overfishing. The focus is on the Victoria Voice radio documentaries aired on CBS radio in the year 2005. The study further explores how three lakeside communities negotiate these issues as radio broadcasts. It recognises that while the mass media contribute significantly to creating public awareness about such social concerns, their likelihood of having a direct and predictable impact on social behaviour is slight. The context and the lived experiences at the reception stage where the decisions are made on whether to adopt an innovation are ultimately the factors which impact on how they are negotiated. The thesis is informed by the theoretical and analytical framework of Cultural Studies as well as the Participatory Approach to Communication for Development perspectives. The study is specifically informed by the theories of ‘discourse’ (Foucault, 1980a, 1981) and the ‘circuit of culture’ (du Gay et al., 1997 and Johnson, 1987) and these provided the conceptual framework for investigating the representations, the production and the consumption of media texts. Predominantly qualitative methods have been employed in data collection and analysis. In the first place, a Critical Discourse Analysis (CDA) (Fairclough, 1995a, 1995c) of the radio texts has interrogated the discourses and discursive practices of CBS’ Victoria Voice environmental radio programmes in order to consider its representations of particular issues and consequently the discourses it privileged. Qualitative methods of participant observation, in-depth interviews and focus group discussions were deployed to investigate the negotiation of the texts by the lakeside communities. This research establishes that the Victoria Voice radio texts foreground three contesting types of discourses: the discourse of basic economic survival and livelihoods is articulated largely by the ordinary people, the lakeside communities; the discourse of sustainable development, particularly the protection and sustainability of Lake Victoria, by scientists and environmental experts; and the discourse of modernisation and corporate investment by politicians and/or policy makers and industrialists. The texts, to a large degree, reaffirm the hegemonic relations of power in Ugandan society, and thus contribute to the maintenance of the status quo. The selection of an elite category of informers (scientists, experts, politicians, policy makers) serves to marginalise the less powerful ordinary people (the fisher folk, farmers and other eyewitnesses). The construction of the elite as active and speaking subjects within the various debates introduced in these programmes, for example, works both to obscure and endorse the unequal power relations. At the reception side, while the lakeside communities attest to the relevance of the programmes in providing information on the issues concerning Lake Victoria and other aspects of their livelihood, they also recognise the power relations that underpin the sets of representations. Amongst these sets is government’s complicity with industry, in line with their economic policies and the global capitalist economy, while espousing the rhetoric of nature conservation. The study argues that sustainable solutions for the crises on Lake Victoria should take into account the socio-historical and cultural contexts of the lakeside communities. For the Ugandan media, particularly radio, there is a need to rethink the nature of the coverage, which tends to neglect the contextual factors, such as local socio-economic and cultural factors within which environmental issues and problems occur and which, as this thesis establishes, greatly influences the way people make sense of environmental issues and problems. I posit that the Participatory Approach that seeks to address the communities’ most pressing concerns should be adopted – to include more of the communities’ voices and involve them in the production of radio programmes.

With the advancement in the current wireless technology standards such as terrestrial digital video broadcasting systems (DVB-T, DVB-T2, and DVB-H) and the massive usage of the Internet over mobile devices, streaming of television channels in smart phones has become a necessary advancement for mobile users. As, UMTS dominating the entire mobile market globally and with the evolution of LTE, several mobile operators are working on an MBMS framework which will help to launch mobile TV services on respective operators. This paper deals with terrestrial and mobile TV with IP multicasting and broadcasting and is aimed to improve system spectral efficiency.  With the help of IP multicasting, the base station can be able to provide with significantly less spectrum by saving it from the channels which the user is not viewing currently. This case is analysed from several sets, called schemes of resource plan sets. The transmitter scheduling is dealt with by means of a Packet and Resource Plan Scheduling (PARPS) algorithm, and the simulated results are plotted in Matlab which assists in analysing the efficiency in the spectrum management and the coverage probability for the number of transmitters used for each scheme. The schemes are simulated in Matlab for different number of transmitters (2-7) in both the static and random model. The SFN schemes are offering greater coverage probability than MFN schemes, in all cases. Multicasting over Continuous Transmission Dynamic Single Frequency Network (CT-DSFN) offers a 1342% and 582% gain in Multi-user System Spectral Efficiency (MSSE) for 7 transmitters, from Broadcasting over MFN and Broadcasting over SFN respectively.  For 7 transmitters, Multicasting over CT-DSFN offers a 1213% and 428% gain in System Spectral Efficiency (SSE) from Broadcasting over MFN and Broadcasting over SFN respectively.

Due to the rapid development of the modern media environment, new formed radio stations challenge the existing ones with creative marketing strategies. Therefore the operating management of a radio station and the image of it become an important issue. In Taiwan, national defense is a rather small topic; therefore how a specialized national defense radio station can survive through such competitive market is worth studying. The research mainly focus on the following issues: The current status of a domestic national defense radio station, the environment factors to effect the organization, and the business management and brand development. The study object is a public owned radio station ran by the department of Defense, “Voice of Han”. The purpose of the study is to find the best business management method and branding strategy for such specialized radio station by theoretical research and data analysis. As the result shows, the research case is hard to become a professional national defense information radio station due to the gap between the targeted audience and the actual ones. Yet the orientation of the station is hard to build up because of the lack of competitive programs and the restrain of resources. The suggestion is to strengthen the brand from the inside of the station, to understand the needs of audience, to produce programs from their view points and to build up a series of identification to unite the brand image.

British broadcasting has undergone significant change in recent years, as the nation prepares to switch from analogue to digital broadcasting. This process has already begun, with the full switch over to the digital platform scheduled in Britain for 2012. Appropriately, at the forefront of the development of digital broadcasting in Britain is its public broadcaster: The BBC. In line with both government, and organisational objectives, the BBC has developed a range of new television, and radio channels aimed at providing a service that will continue to be appropriate to audiences further into the twenty-first century. This research examines the output of two BBC music radio stations, Radio One and 1xtra, considering how changes to management, policy, and strategy in each station can affect the output they broadcast. Radio One and 1xtra both use a strategy of broadcasting new music to target a youth audience. However, Radio One is a mixed-genre station broadcasting on analogue radio, while 1xtra is a niche station broadcasting on the digital platform. By comparing the stations I attempt to draw conclusions about the BBC’s digital strategy, and what implications these have for the output of both Radio One and 1xtra in the digital age. Discussion in the first half of the research focuses on the internal operations of the BBC. I consider the BBC’s approach to the diversity of the content it broadcasts, and what this approach reveals about the different priorities of the organisation. Close examination of the management changes made at both an organisational, and individual station level provide further insight into the context guiding priorities and policy decisions made in the BBC, Radio One, and 1xtra. The second half of the research pays greater attention to the actual output broadcast by Radio One and 1xtra, using content analysis methodology to measure similarities, and differences between the two stations. Through the simultaneous examination of management and policy changes, and of the output broadcast by the two stations, I aim to make conclusions about how changes made internally have had a direct impact on the diversity of music broadcast on Radio One and 1xtra.

1 RESUMÉ This dissertation focuses on selected aspects of copyright and rights related to copyright in connection with radio broadcasting. It specializes in use of authors' works, artistic performances of performers and phonograms of phonogram producers in the way of radio broadcasting and on internet connected to radio broadcasting according to the current legislation in Czech Republic. In the first part it concentrates on items of copyright protection, their use in radio broadcasting, on broadcasters as users in the view of copyright law, on licence agreement, term of protection and radio broadcasting itself. As far as the broadcasting is concerned the dissertation approaches it in the view of administrative law focusing on its content. In the second part it deals exclusively with collective rights management as with the key institute for broadcasters to get appropriate copyright licences to use the protected items. It concerns the compulsory and voluntary collective rights management, the cumulative agreements and royalties, and collecting societies operating in Czech Republic. With regard to the present trends this dissertation, in its third part, aims at broadcasters' activities on internet and further platforms. The last part is devoted to several nowadays issues in copyright, such as extension of...

As the local radio broadcast industry underwent a drastic revamp since 1993 following a series of ratio frequency deregulations by the government opening up opportunities to file for broadcast licensing, privately run radio broadcast stations have begun to thrive and eventually become mainstream in the broadcast business. As a majority of the emerging radio broadcast stations are of medium to small frequency powered radio stations, and as restricted by radio wave frequency projection, the service coverage tends to be limited to within a radius of 5 to 20 kilometers of a moderate range, yet with a relatively moderate scale of equipment investment and operating capital. At which, the number of legally registered radio stations has mushroomed in the past decade, presently there are a total of nearly 160 radio broadcast stations that are legally registered to compete the piece of the action and share the broadcast advertising pie. With a limited market scale, the radio broadcast industry finds itself enthralled in an unavoidable heated market competition as new operators rush to joint the marketplace in multiple numbers. As a result, it is not surprising that radio station operators would need to ponder how best to secure a nice market through business management thinking of audience segregation, professionalism and strategic pact. Managing an audience-specific market has benefited from diverse listening choices available to the mass audience, which in turn allow the broadcast industry to take to a diversified development feature to harbor content enrichment. Yet, notwithstanding the emerging force does contribute towards breaking down the once monopolistic industry dominated by a few powerful stations, coupled with certain loopholes in government regulations, the developing trend, nevertheless, has posed certain impact to the structure and landscape of the radio broadcast industry, and ramifications derived from the development only further accelerates business operating difficulties that test the wits of the radio broadcasters. The study aims to examine how the conventional radio broadcast stations confront a drastically fast-changing marketplace, and how they evolve in operating philosophy and mentality, and move to revamp their management and adjust their strategies, and some of the more drastic moves that they have sought in transforming from a mass broadcast market to an audience-specific market. A station that has successfully transformed itself into one positioned as a finance, economic and money-management oriented one has been taken as an example to further profile and examine the process through in-depth interviews and hands-on participation and field observations broaching from the practical viewpoint. One other objective has been to propose the author’s humble input and to contribute some of the study findings deriving from such type of station managing knowledge accumulated on some of the crucial focuses required for a radio broadcast station once focusing on mass audiences to transform itself into an audience-specific broadcasting establishment.
