This study aims to analyse the process of digital switchover in the UK, which is regarded as one of the most successful cases in the world, and to examine efficient plans for the future digital switchover project in Korea through the UK's case. The digital switchover in the UK shows with no doubt the significance of integrated government policies, collaboration between relevant governmental organisations, and the public service broadcaster. Along with this, active and detailed Public Relations (PR) should take place, helping the citizens realise the efficiency of the phased switchover region by region and the measures to resolve the gaps between all social brackets. To sum up, the successful digital transfer is not only achieved by governmental policy and technological preparation from broadcasters, but also by voluntary citizen participation. Government officers and broadcast executives need to realise this and should focus on communicating with citizens.

Thanks to the circumstance of digital convergence, most of the world TV and radio stations are gearing up for digitalisation of broadcasting. In this flux, digital switchover in South Korea should be completed by 2012 when transmission of analogue broadcasting signal will be ceased. According to the report, it shows only over 30% take up roughly so far, but there is no official survey from relevant organisation. It is very comparable with British digital switchover which is same year as S. Korea and has been reported 88% take up as of 2008 Q2. Yet the digital switchover in S. Korea inferred from this current is not a rosy future and even seems to be perilous. The purpose of this paper is to predict the media future of S. Korea at the view point of futurology and draw out the possibilities which enable to affect viewing behavior. In order to analyse it applies the futures wheel which is one of useful tools for future work. Consequently it suggests a number of scenarios how to cope with the impending situation in S. Korea.

A demand for spectrum resources, especially in the low frequency bands, is ever increasing with the development of mobile telecommunications and so is their economic value as other national resources. Also, development in mobile broadband require more bandwidth with excellent propagation characteristics, such as those frequencies in the 700/800/900 MHz bands. As a way to enhance the economic efficiency of using spectrum resources, many countries including the U.S., the U.K. and Japan, have recently focused on the refarming plan of the low frequency bands according to the transition from analogue to digital TV. By the way, as a result of WRC-07, those parts of the band $698{\sim}960\;MHz$ in Region 2 and the band $790{\sim}960\;MHz$ in Regions 1 and 3 which are allocated to the mobile service on a primary basis are identified for use by administrations wishing to implement International Mobile Telecommunications (IMT). Therefore, after analogue to digital television switchover, some administrations may decide to use all or parts of the band $698{\sim}806/862\;MHz$ for other services to which the band is allocated on a primary basis, in particular the mobile service for the implementation of IMT, while in other countries the broadcasting service will continue to operate in that band. And to conclude, bands already identified for IMT-2000 will also be able to be used for IMT. This work will help establish a policy direction for spectrum refarming in the low frequency bands in Korea(Rep. of).

The public concept of digital broadcasting is all about anytime, anywhere and anyone. It implies that the viewing rights of digital broadcasting have to be blessed with anyone, in anywhere and at anytime. Here anyone connotes the notion included visually and hearing impaired viewers as well as the non-disabled. Considering the current circumstance, which is a milestone of digital switchover by 2012, it seems destitute of the accessibility for the disabled. Hence this study is to manage the embodiment of broadcasting accessibility in digital interactive services originated from W3C for impaired viewers in order to cotton to the unlimited contents on digital television.

Japan TV broadcasting signals are measured and analyzed to estimate spillover level from Japan during 44 months from Feb. 2003 to Oct. 2009. Electric field intensity spillover into Korea is measured using fixed measurement system in Busan, and the relationship between the measured data and the predicted value is analyzed by year and seasons. Measurement results show that spillover signals from Japan have a serious effect on Korea broadcasting environment, and so that proper digital switchover strategy is necessary to cope with the spillover situation.

This paper addresses the implementation of FTTH system based on G-PON technology. This system supports the duplication function that can switchover both TDM and data routes within 10msec. This system consists of OLT and ONU/ONT. G-PON OLT supports the maximum 32 2.5Gbps interfaces, and then has the flexibility and the scalability for supplying digital communication and broadcasting convergence service in the near future. OLT system consists switch module, subscriber module, processor module, and G-PON link module, and has the operating system based on Linux. ONU is installed in customer premise to supply TPS (Triple Play Service). Also ONT has the dedicated interface for IP-TV to improve the transmission characteristics of IP-TV signal.

To fully utilize scarce spectrum resource, it's necessary to develop and evaluate promising business models prior to making technology R&D plan and industrial promotion policy. The purpose of this paper is to design potential business models, evaluate the propriety of commercializing the models, and discuss promotion policies after exploring promising sectors consuming spectrum resources. The research is based on TV white space, which is vacant TV channels in region or time domain and considered as core spectrum resource along with digital terrestrial television switchover. As the result, four kinds of business models were derived, including broadcasting and telecommunication types. Each model was discussed from four standpoints: customer value proposition, profit formula, key resources, and key processes, and the propriety for commercialization was evaluated by three dimensions: technological evaluations, business-oriented evaluations, and user-oriented evaluations. The promotion policies of government and market participants for the activation of TV White space-based business models were discussed as well.

The Terrestrial DTV service compliant with ATSC has been advancing for years. In KBA(Korean Broadcasters Association), a multi-channel service was broadcasted on air during the period of the 2006 FIFA World Cup Germany with the various type of MMS(Multi Mode Service) using MPEG-2 encoding method. MMS Service can provides not only one HD channel but also serveral additional services within 6MHz bandwidth. Using digital video compression technology(MPEG-2), many various programs such as HDTV, SDTV, Audio and Data are able to be transmitted within the same bandwidth. From November 2009, KBS has been preparing an advanced MMS service, 'Korea-View' which has both methods of encoding, MPEG-2 and H.264 that is compliant ATSC mobile standard, A/153. Korea-View is a kind of multi-channel broadcast service to provide one HD and 3 SD programs with the bandwidth of 6MHz. Terrestrial multi-channel service is required to focuse on expanding viewer service. Such Terrestrial multi-channel services will contribute to transferring to digital broadcasting and to extending the viewers' welfare. Due to advances in digital technology, Pay-TV channels has increased to hundreds. Even though digital switchover is being proceeded, terrestrial broadcasters have been unable to deliver multi-channel services. In this paper, technical features and differences of MMS and Koreaview will be analyzed regarding terrestrial multi-channel broadcasting services, and the politic direction will be proposed in accordance with introduction of future service.
