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.

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.

In this paper, we proposed the new medium access control protocol for the virtual token bus netowrk. The network is applied to inter-processor communication network of large capacity digital switching system and digital mobile system with distributed control architecture. in the virtual token bus netowrk, the existing medium access control protocols hav ea switchove rtime overhead when traffic load is light or asymmetric according ot arbitration address of node that has message to send. The proposed protocol optimized average message delay using cyclic bus access chain to exclude switchover time of node that do not have message to send. Therefore it enhanced bus tuilization and average message delay that degrades the performance of real time communication netowrks. It showed that the proposed protocol is more enhacned than virtual token medium access control protocol and virtual token medium access control protocol iwth reservation through performance analysis.

This paper presents the duplex controller operated as master slave for Self Excited Static Type excitation system and the results of operation for duplex digital excitation system. Software is made up duplex multi-tasking control algorithm which is based on VxWorks(real-time OS), preprocessing algorithm for input-output signal, BSP & Device Driver for interfacing hardware and software, and OIS(Operator Interface Station) program, HMI S/W. Master controller and slave controller intercommunicate dominant data to minimize bump when controller switchover from master to slave occurs. Communication between master controller and slave controller is duplicated and communication between OIS and controller is duplicated. Hardware is made up VMEBUS based controller which is designed with PPC & I/O board ...

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.

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).

As smart convergence occurs, solving the digital divide issue for weak layers such as the elderly, handicapped and poor groups is becoming an emerging issue. This study aims to promote information service to encourage active participation of the weak layers and to bridge the digital divide among those under the digital switchover and the smart phone convergence environments. This study, comparing the environments of Korea and other major countries with respect to digital divide, found some differences and tried to suggest proper policies for Korea to remain as a leading IT country. We expect this study to help the government, industries, schools cope with the divide issues and establish proper policies to provide weak layers with equal opportunities to IT in the coming smart convergence era.
