차세대 방송 서비스 전망과 기술 개발 전략: 초고품질 UHD

Abstract

With the help of the recent acceleration of broadcasting services, the improvement of broadcasting technologies is now welcoming the era of UHD(Ultra High Definition) broadcasting services beyond this era of Full-HD broadcasting services. Already most of the world’s leading digital TV manufacturers had finished the commercialization of 3840x2160 resolution on the 4K UHD display devices and are now competing fiercely for popularization. The 4K is four fold better than Full-HD 1920x1080 resolution. Considering such change in the market, no one would deny how the outlook for UHD which is emerging as a trend in the field of broadcasting will be discussed as a definite fact. However, despite the evolvement of HD into 4K UHD, an issue claiming that the resolution of a screen which had been expanded by four times is not simply impressive enough to invite viewers to any new greater inspiration has arisen and as a consequence, TV manufacturers are now focusing on finding another technology pursuing a motto, “Toward UHQ(Ultra High Quality) beyond UHD: Better pixels than more pixels”, in order to enhance reality and presence. In the light of that, this thesis introduces not only high-quality UHD(UHQ) that would dramatically increase the next generation broadcasting service quality with the most impressive perceptual quality compared to that of the existing UHD but also the competitiveness of broadcasting equipment industry. As a next step, the study looks into present circumstances of next generation broadcasting policies and technology developments in different countries and Korea as well as the level of technology in the latter nation to analyze competitiveness and in the end, that helps the study come up with strategies on how to promote UHQ-based technology development.
