The exploitation of TV white spaces can meet the increasing demand for spectrum resources and create opportunities for deploying a variety of wireless services in a flexible manner. However, uncertainties from technologies, business models and regulatory policies hinder the take-off of TV white spaces exploitation. This paper proposes a bicameral (or two-chambered) geo-location database, which allows/supports both free and paid access to the TV white spaces: i.e., one chamber supports free access through opportunistic or geo-location database access; and the other chamber supports paid usage through secondary spectrum trading. Consequently, four technological scenarios for the acquisition of TV white spaces emerge, namely: sensing only, joint sensing and geo-location database access, geo-location database access only, and broker based secondary spectrum trading. An analysis of these scenarios is performed based on a theoretical framework for emerging technology evaluation while considering technological, business models and regulatory dimensions. The analyses show that free and paid access to TV white space complement each other; and that despite considerable infrastructure costs, the bicameral geo-location database is positioned to create viable TV white spaces exploitation value chains; hence have the most optimal technological, business and regulatory prospects.  相似文献

We examine the potential for expansion of the white space spectrum sharing model in the 400 MHz band. As opposed to UHF broadcast spectrum, which contains unassigned or idle segments known as white spaces, the 400 MHz band is characterised by intensive licence usage. However, productive spectrum usage does not guarantee allocative efficiency, which would require knowledge of the highest value service for each licence. 400 MHz frequencies are not priced on opportunity cost. It is therefore difficult to ascertain the economically efficient mix of services to deploy in the 400 MHz band. Drawing parallels with the high-economic value revealed and generated through the operations of unlicensed white space devices in UHF broadcast spectrum, we identify untapped 400 MHz spectrum capacity, which we refer to as narrowband spaces. Encouraging dynamic spectrum usage of narrowband spaces could, similarly to TV white space usage help realise the efficient allocation of the 400 MHz band. However, the narrowband nature of the 400 MHz licences and high licensing turnover imply a significantly different concept of dynamic spectrum access than that considered for TV Bands. The paper discusses regulatory implications and the type of services suited to exploit narrowband spaces.  相似文献

This article addresses complicated convergent and regulatory issues arising from cross-platform audiovisual services and analyzes Singapore's multi-screen television experience. A “platform neutrality” multi-screen TV regulatory scheme is proposed to concentrate on content classification in order to respond to the fast-changing audiovisual industry and competition. Under the scheme, different content and license regulations are applied to four types of TV-like services which are categorized by “socio-cultural impact” (i.e., broadcasting and mass market vs. VOD and niche market)” and “content production/aggregation model” (i.e., gatekeeping vs. participatory mechanism). In addition, competition, content regulation, and digital copyright are identified as key issues involved in the fast-growing cross-platform audiovisual media industry. Finally, this study analyzes market development, regulatory issues, and national plans for multi-screen TV services in Singapore and examines them under the proposed regulatory scheme. Market and policy recommendations are discussed.  相似文献

This paper is a contribution to the development of analyses of the process of converging media and to the clarification of the regulatory implications of this process. It is generally agreed that the process of convergence between telecommunications, IT and broadcasting through its technological, organisational, and market/service aspects has far-reaching influence on the sectors involved and on future socio-economic settings. The paper explores the preparation for introduction of terrestrial digital television in Denmark as an aspect in the general process of convergence. The explorative analysis establishes an understanding of the technological issues and drivers in the development, which in interaction shape a digital distribution structure that is a concrete part of convergence. Based on this understanding, a model – the OSA-model – is suggested for the techno-economic structure of distribution of terrestrial digital TV. The model is used to discuss market prospects and regulatory implications, as these are derived from the interplay of traditional areas of regulation in the three sectors and areas emerging as candidates for regulatory activity based on their functionality. The discussion of the process of introduction of terrestrial digital TV in Denmark thus provides a general analysis of convergence and its regulatory implications.  相似文献

The rush to understand new socio-economic contexts created by the wide adoption of AI is justified by its far-ranging consequences, spanning almost every walk of life. Yet, the public sector's predicament is a tragic double bind: its obligations to protect citizens from potential algorithmic harms are at odds with the temptation to increase its own efficiency - or in other words - to govern algorithms, while governing by algorithms. Whether such dual role is even possible, has been a matter of debate, the challenge stemming from algorithms' intrinsic properties, that make them distinct from other digital solutions, long embraced by the governments, create externalities that rule-based programming lacks. As the pressures to deploy automated decision making systems in the public sector become prevalent, this paper aims to examine how the use of AI in the public sector in relation to existing data governance regimes and national regulatory practices can be intensifying existing power asymmetries. To this end, investigating the legal and policy instruments associated with the use of AI for strenghtening the immigration process control system in Canada; “optimising” the employment services” in Poland, and personalising the digital service experience in Finland, the paper advocates for the need of a common framework to evaluate the potential impact of the use of AI in the public sector. In this regard, it discusses the specific effects of automated decision support systems on public services and the growing expectations for governments to play a more prevalent role in the digital society and to ensure that the potential of technology is harnessed, while negative effects are controlled and possibly avoided. This is of particular importance in light of the current COVID-19 emergency crisis where AI and the underpinning regulatory framework of data ecosystems, have become crucial policy issues as more and more innovations are based on large scale data collections from digital devices, and the real-time accessibility of information and services, contact and relationships between institutions and citizens could strengthen – or undermine - trust in governance systems and democracy.  相似文献

The transition to digital television transmission (DTT) creates an opportunity for revising the current allocation and use of the spectrum, and for enhancing its efficiency. The fairly large amount of spectrum that will be freed up in the analog TV switch-off is known as the digital dividend. Many EU countries have decided to partially allocate these frequencies, through market mechanisms, to mobile use, but a large fraction of the dividend is supposed to remain in the hands of broadcasters. An efficient management of the spectrum requires that the use of this resource should be supported through appropriate incentive policies. This paper presents a techno-analytical approach to evaluate the opportunity cost of using a spectrum portion within the digital dividends’ bandwidths, for example around 800-900 MHz, for both DVB-T and UMTS services, specifically addressing the extraordinary rise in the use of mobile broadband in the European context. The methodology is then applied to Italy to derive a baseline for administered prices reflecting the cost of spectrum use. Results obtained are then compared with existing evidences from other studies and Countries’ experiences.  相似文献

This paper compares the regulatory incentives created by government policies aimed at promoting the transition to digital TV in the US, France, and the UK. It argues that US policies have aggravated coordination problems and even created incentives for terrestrial broadcasters to retard the transition in order to receive compensations from wireless telecommunications providers for vacating frequencies before the statutory deadline. The institutional analysis framework is applied to explain the observed policy variations across countries as well as the factors retarding the transition in the American case. The conclusion suggests possible remedies to accelerate the transition to digital TV in the US based on the British experience.  相似文献

The increased economic importance of digital services has profoundly changed the power structure in telecommunications and media markets. Although these services sometimes directly compete with traditional telecommunications services, the regulatory obligations for both players differ significantly. This article discusses three important areas deemed relevant in order to define a coherent regulatory framework and to account for the specific peculiarities of digital markets: First, challenges associated with assessing market power in digital markets. Second, challenges in harmonizing different regulatory obligations for digital services, and third, the vital role of data and data protection in the context of data-driven business models.  相似文献

Technology competition between wireless communication technologies can lead to new, more or less disruptive services. A potentially disruptive technology would be to have unlicensed transmission in the lower UHF bands at power levels up to, e.g. 2 W EIRP. This would give citizens a share of the best spectrum for free use. Tools against congestion could be based on mandatory stochastic channel back-off or, if multiple users are present, on adaptive power and bandwidth control. Compared to the FCC TV white space regulation, no back link would be needed as the spectrum would be used exclusively by wireless devices. In an environment of shrinking interest in terrestrial TV broadcasting, such a regulation is expected to create a new market for high-range consumer devices, competing with licensed communication, while also being suitable for offloading traffic from licensed operations. Furthermore, the approach will allow for efficient digitization of equipment for Programme Making and Special Events (PMSE), but could also be made compatible with novel disaster relief services. To enable accurate interference prediction, it is proposed that, instead of only providing transmitter regulation, receivers should also be regulated, such as be required to adhere to a certain minimum selectivity. The proposal should be taken up in the WRC process.  相似文献

Beginning with the historical role and importance of multi-physical standards in wireless telecommunications for the future in the US, Japan and Europe, this paper provides a cohesive vision of how wireless communication, voice over Internet protocol (VoIP) is likely to develop. Also covered in this paper are its benefits, the technical and regulatory support required to realize this vision and an assessment of its potential impact on the structure of the telecommunications industry. Although the competitive structure of the Internet is relatively open, several factors, such as frequency allocation policy and radio interface standards, could block the efficient evolution of wireless services to an IP platform. The paper proposes two major technical requirements to enable effective competition in wireless VoIP and achieve greater technical productivity.  相似文献

We consider two different qualities of broadband access, one that simply means greater access speed to Internet applications and content, and a premium version that also gives access to interactive TV services. Based on a market survey we find that potential consumers of this premium broadband access do not consider basic broadband Internet access as a substitute. The price of basic broadband does not constrain the price that may be charged for the premium broadband that allows for interactive TV services.  相似文献

This article surveys how convergence is dealt with in the main areas of EC competition law. First, under Article 90 EC Treaty, the Commission has not yet reached a solution to the problems of TOs holding exclusive rights over cable TV networks or providing broadcasting services over their telecommunications networks. Secondly, while the Commission has largely upheld certain policy lines in individual decisions, it has reached markedly different outcomes in the broadcasting and telecommunications sectors. The Commission has not been able successfully to integrate non-economic factors in its competition law analysis. Third, State aid problems are likely to arise in relation with production subsidies and compulsory broadcasting fees. In the end, competition law must still evolve to deal with convergence, but in doing so it is likely to pre-empt regulatory options.  相似文献

Are audiovisual over the top (OTT) services in Latin America substitutes for the traditional Pay TV services (cable or satellite), complementary or independent? To respond to this question, we develop a simple theoretical model based on a CES utility function and estimate simultaneously, using non-linear least squares, demand functions for both audiovisual services. Our results, based on original database covering 17 Latin American countries from 2011 to 2020, suggest no substitution of Pay TV for OTT. However, during the more recent period (2015–2020), we find evidence of gross substitution (i.e., similar enough, although not completely equivalent for consumers) between these audiovisual services. This confirms, although only partially, the existence of the so-called cord-cutting and cord-saving phenomena, due to the expansion of fast internet and the richer OTT offers, and their relatively lower prices. These results suggest regulators should include OTT services in their scope and produce in-depth analysis on the country level to update and optimize regulations, as well as implement regulatory sandboxes to advance towards smart regulation, as shown in the financial industry.  相似文献

This article examines the roles and consequences of different approaches to 5G market design for innovation. The analysis is grounded in a conceptual framework that explicitly considers the complementarities among networks, applications, and services. Good policy arrangements align the legal and regulatory framework with the technical and economic characteristics of the sector and the broader, social visions for new technologies. Because the future development of 5G technology and markets is open-ended, policy has to be developed with incomplete knowledge and under conditions of uncertainty. These circumstances call for adaptive forms of policy and a focus on the creation of guardrails for market players, backed up by regulatory powers to intervene more directly if necessary. In the technologically dynamic 5G system, multiple stable policy constellations are feasible, but they likely will result in divergent outcomes and performance characteristics. Monitoring of the experience with different national and international developments will facilitate global learning and the incremental improvement of policy frameworks.  相似文献

This paper explores the impact of policies made by the State Administration of Radio, Film, and TV on China's transition to digital TV. The method of stakeholder analysis is used to present a theoretical study on the digital transition, with a quantitative model analyzing the welfare change of three segments of consumers. A simultaneous-equation model is used to study the characteristics of the demand and supply of digital TV in China. It is argued that the policy of uniform transition that ignores coordination among stakeholders does harm to consumers’ benefits, and the healthy and sustainable development of China's cable digital TV industry. In an introductory phase of digital TV, educating consumers with convenient and pleasing experience is essential, and restructuring cable operators in a market-oriented way is also critical for developing countries like China.  相似文献

Firms are investing an increasing amount of time and resources to gather information about market and technology in new product development (NPD). Yet there is a lack of consistent understanding of whether such costly information generation activities can improve product outcomes. More importantly, it is unclear how the benefit of market information and technical information generation may differ and how they may jointly impact new product performance. This study examines the role of market and technical information generation in NPD in three ways: (1) It contrasts the effects of market and technical information generation on product outcomes; (2) it identifies conditions that moderate the effects of market and technical information generation and further investigates how the moderating effects differ for these two types of activities; and (3) it examines the joint effect of market and technical information generation to understand potential synergies between them. Using survey data at the NPD project level, we find that market information generation has an inverted U‐shaped effect on new product advantage, whereas the effect of technical information generation follows a U‐shape. Furthermore, these effects are moderated differently by two conditions: a firm’s R&D intensity that influences NPD projects’ need for different types of information, and the use of multidisciplinary teams that affects the degree to which information can be shared and utilized to improve product design. The findings provide important implications for organizational learning and shed light on how to manage information generation activities to achieve NPD success.  相似文献

This article analyzes Internet Service Provider costs and regulatory and policy issues raised by Internet telephony. Transport and non-technical items such as customer service, sales and marketing, represent a substantial portion of an ISP’s costs with Internet telephony. Pricing models and yield management techniques supporting Internet voice services might be employed for other Internet differentiated services as well. An integrated regulatory framework will be required, because of convergence, to formulate policies for multimedia services. We conclude that governments should develop appropriate policies without introducing economic and technical distortions into the nascent Internet telephony market.  相似文献

The aim of this paper is to present a quantification approach for the calculation of the ICT sector's structural effects in the economy, focusing on the case of Greece. We construct a composite sector using a hypothetical extraction methodology based on the most recent Greek input-output table and structural business statistics at the national level. Our framework builds on the formal definition of the ICT sector provided by OECD and includes two distinct sub-components, ICT manufacturing and ICT services. In the second stage of this study, we explore the production linkages among ICT services, ICT manufacturing and the rest of the Greek industries using input-output-based and network analysis-based metrics that build on the intermediate transactions of an expanded input-output table of the Greek economy that includes the two sectors. Our empirical findings suggest that the total ICT sector has a major contribution to the Greek economy in terms of GDP and employment, but this is driven mainly by the ICT services component. We further identify that ICT services are more integrated in the Greek production network compared to ICT manufacturing, but their production linkages are underperforming in terms of meaningful contribution to the activity of the rest of the sectors. These results reflect the low integration of digital technologies and can be further embedded in a discussion on the ICT deficiencies of the Greek economy and the need for targeted regulatory and financial interventions.  相似文献
