    Germany's broadband networks - innovation on hold

    Get PDF
    The market for information and communication technologies is changing rapidly. Products and applications that used to be completely separate are becoming almost interchangeable. Sweeping change lies ahead in voice and data telephony: the fixed-line telephone network faces new competition from innovative technologies. In this report we concentrate on analysing the economic potential of TV-cable and powerline networks as internet-access media, and discuss the prospects for the communications market. Besides looking into the technological developments, we examine the market relevance of existing ownership and competitive structures.ICT, cable, Germany, Broadband

    Three scenarios for TV in 2015

    Get PDF
    By offering three visions of the future of television through 2015, this article aims to highlight some of the socio-economic changes that the television sector may experience in the long term. It highlights the structuring impact that PVR could have on the sector, as well as the upheavals that may arise from a new paradigm of internet TV. It also highlights the options now open to TV channel operators wishing to set up a mobile TV service and the threats facing mobile telecommunications operators in the development of this market as a result.television; forecast; media usages

    Media fusion and future TV: Examining multi-screen TV convergence in Singapore

    Get PDF
    This study examines Singapore's national media blueprint and industry stakeholders' coping strategies in response to multi-screen TV development. The findings show Singapore muti-screen TV development is still at a nascent stage after launching Media Fushion and FutureTV plans in mid 2009. The policymakers play a key role to follow national media blueprint to unify the inter-industry and cross-country collaboration. TV operators and telcos are found to remediate themselves by harnessing the power of internet and mobile technologies for content innovation and distribution. To tackle the complicated convergent issues in multi-screen TV industry, this study proposes to separately regulate the technology-neutral platforms and diverse audiovisual content. It also recommends a pro-innovative policy with the light-touch licensing scheme and loose content regulation to facilitate the development of the next TV. --three-screen TV,multi-screen TV,convergence,media fusion,IPTV,mobile TV,cross-platform,TV technologies,TV market,TV policy

    What's Going on in Community Media

    What's Going On in Community Media shines a spotlight on media practices that increase citizen participation in media production, governance, and policy. The report summarizes the findings of a nationwide scan of effective and emerging community media practices conducted by the Benton Foundation in collaboration with the Community Media and Technology Program of the University of Massachusetts, Boston. The scan includes an analysis of trends and emerging practices; comparative research; an online survey of community media practitioners; one-on-one interviews with practitioners, funders and policy makers; and the information gleaned from a series of roundtable discussions with community media practitioners in Boston, Chicago, Minneapolis/St. Paul, and Portland, Oregon

    3D video coding and transmission

    Get PDF
    The capture, transmission, and display of 3D content has gained a lot of attention in the last few years. 3D multimedia content is no longer con fined to cinema theatres but is being transmitted using stereoscopic video over satellite, shared on Blu-RayTMdisks, or sent over Internet technologies. Stereoscopic displays are needed at the receiving end and the viewer needs to wear special glasses to present the two versions of the video to the human vision system that then generates the 3D illusion. To be more e ffective and improve the immersive experience, more views are acquired from a larger number of cameras and presented on di fferent displays, such as autostereoscopic and light field displays. These multiple views, combined with depth data, also allow enhanced user experiences and new forms of interaction with the 3D content from virtual viewpoints. This type of audiovisual information is represented by a huge amount of data that needs to be compressed and transmitted over bandwidth-limited channels. Part of the COST Action IC1105 \3D Content Creation, Coding and Transmission over Future Media Networks" (3DConTourNet) focuses on this research challenge.peer-reviewe

    Bundling, Differentiation, Alliances and Mergers: Convergence Strategies in U.S. Communication Markets

    Get PDF
    Convergence is a multi-facetted phenomenon affecting the technological basis of information and communication industries, the boundaries of existing and new markets, and the organization of service providers. Convergence in substitutes will tend to increase the intensity of competition but convergence in complements may have the opposite effect. Given the economics of advanced communication industries, convergence necessitates strategies to overcome the risk of commodification at the level of networks, applications, and services. The paper examines bundling, differentiation, alliances, and merger strategies adopted by North American service providers in response to convergence. Service providers'opportunities and risks in the emerging environment differ considerably, with cable and telephone service providers presently in stronger positions than wireless service providers, broadcasters, and satellite service providers. New entrants such as Vonage, Skype, Google, and Yahoo have high disruptive potential but remain disadvantaged without their own access networks.convergence; bundling; differentiation; alliances; mergers

    A survey of digital television broadcast transmission techniques

    No full text
    This paper is a survey of the transmission techniques used in digital television (TV) standards worldwide. With the increase in the demand for High-Definition (HD) TV, video-on-demand and mobile TV services, there was a real need for more bandwidth-efficient, flawless and crisp video quality, which motivated the migration from analogue to digital broadcasting. In this paper we present a brief history of the development of TV and then we survey the transmission technology used in different digital terrestrial, satellite, cable and mobile TV standards in different parts of the world. First, we present the Digital Video Broadcasting standards developed in Europe for terrestrial (DVB-T/T2), for satellite (DVB-S/S2), for cable (DVB-C) and for hand-held transmission (DVB-H). We then describe the Advanced Television System Committee standards developed in the USA both for terrestrial (ATSC) and for hand-held transmission (ATSC-M/H). We continue by describing the Integrated Services Digital Broadcasting standards developed in Japan for Terrestrial (ISDB-T) and Satellite (ISDB-S) transmission and then present the International System for Digital Television (ISDTV), which was developed in Brazil by adopteding the ISDB-T physical layer architecture. Following the ISDTV, we describe the Digital Terrestrial television Multimedia Broadcast (DTMB) standard developed in China. Finally, as a design example, we highlight the physical layer implementation of the DVB-T2 standar
