This study investigates whether the use of N-screen service affects the use of Home TV service as a supplement or substitution. In this study, we collected 132 available survey answers from CJ Hellovision Tving users. We found supplement relationship between Tving and Home TV, which implies that the more use in Tving service, the use of Home TV increases as much as 36.4%. From the result, some meaningful implications were derived. First, a direction for content price negotiation between N-screen providers and terrestrial broadcasters can be suggested. Second, the result will provide a suggestion for establishing a competitive strategy between N-screen providers and Pay-TV providers. Third, this study may solve copyright dispute between content providers and pay TV operators.

EBS started 2HD MMS experimental broadcasting for the first time in Korea on Feb. 11, 2015. It uses the picture compression technique based on MPEG-2 CODEC, and applies the result of the experiment about variable bit rates and changes according to the scanning types, 1080i and 720p. But when changing channels, the delay in displaying picture occurs because of the operation of the variable GOP on MMS broadcasting, which optimizes image quality by application variable bit rates. In this study, verified the relationship between the decoding time of I frames and the GOP set in the encoding step by experimenting and analyzing ON-AIR TS. By using the verification data and adjusts the Encoder GOP parameters, improved the different video display time delays according to the scanning mode 1080i and 720p.

This paper analyzes the demand characteristics of DMB services using survey data. According to a Logit analysis, the willingness to adopt the services is higher if the would-be user is male, is better informed with the service, is watching TV longer, and is spending more for the telecommunications services. And the survey results tell us that for the stimulation of the service, efforts should be made to increase the level of public awareness of the services. The survey response from the would-be DMB users shows that the respondents who value the nationwide coverage and the numbers of channel are more inclined to use the satellite DMB service. On the other hand, the service charge and the availability of the terrestrial broadcasting channel for the time being does not seem to influence the intention of using the terrestrial DMB service. It could be interpreted that the potential user are deciding whether to use the service more by the quality and contents of the service rather than by the cost of the service.

The aim of this study is to analyze the distribution structure of exclusive digital muti-media broadcasting's contents. This study takes into distribution wether exclusive contents create an additional window being serviced to other media. And it investigates how the contents work in window through analysis of programming table and interview with programming editors of each DMB service company. The window effect is a same notion to the one source multi use. In the film industry, window means a movie distribution that a film can be on one after the other starting the cinema, DVD, local cable channel, and terrestrial television. The key point of this paper is how to new media, DMB, creates its additional window and changes the existing window structure.

In this paper, we simulated disaster broadcast service using terrestrial UHD additional data. We looked at nine functions(warning alarm, location-based information, multilingual, re-viewing the title of breaking news, evacuation knack video, CCTV, clip video, wake up, automatic channel switching) by referring to ATSC 3.0 standards. Analyzing the advantages and problems of the proposed disaster broadcast. Expert interviews were conducted after a demonstration and explanation of terrestrial UHD disaster broadcast. They said that the problems with the technology were difficulty in using, obstruction of viewing, content creation problems, and problems with advertisers. In addition to the lack of simulation-based research, this research has provided an insight into the technology by showing it in a visible way. This helped shape the advantages and problems of technology.

The study empirically analyses a linear relationship between terrestrial advertising rates and viewer ratings. Consistent with the results of preceding studies, the present study finds a convex relationship between standard advertising rates and viewer ratings. However, after all other sales practices are taken into account, a linear relationship is documented between per-minute advertising revenue and viewer ratings. Absent the exact functional relationship between the two, it is hard to evaluate accurately how efficiently or inefficiently the current GS System has operated, but it tells us that a certain level of market mechanism prevailed within the system. The findings are consistent with the 1 Public-1 Private Media Representative alternative among many alternatives currently sought by the KCC should we accept the premise that the public aspect is as equally important as, if not more important than, the efficiency aspect of terrestrial broadcasting.

Variety media based on the digital technology have emerged from the beginning of the 21th century and have competed with the traditional media in the advertisement market. With the high dependency upon the advertisement market, the Korean media industry has the urgent demand to increase it's pie. Korea regulator allowed PPL and private representatives, which resulted in low outcome. This study analysed the decision factors for the advertising market with the cross-sectional microeconomic data for 28 countries in OECD. The service industry, tax and GDP per capita affect negatively to the market growth rate, and unemployment positively. Therefore the market's growth speed would be slow down and the share of TV decreased. Therefore the two policies were suggested, increasing the direct payment by the audiences and retire of the inefficient broadcasters.

Terrestrial broadcasters are devoting great efforts in order to increase sense of reality that would help viewers feel as if they were watching events on site by producing-depth, differentiated news and offering a variety of information to them. They maximize news video graphic effects by replacing news set and install large display units, rail camera, and Jimmy Jib camera. This study aims to grasp whether there is any difference among the main evening news of the three major terrestrial broadcasters. KBS, MBC, and SBS used 18%, 15%, and 12% of graphic usage hours respectively while the number of graphic usage cases amounted to 267, 329, and 276 for each of them. The number of cases where in-depth news report hours exceeded three minutes that require increasingly more virtual reality graphic technology production was 16 for KBS, 7 for MBC, and 5 for SBS. MBC showed the highest number of uses in graphics while KBS showed more graphic use hours than the other two. There have been a number of preceding studies on news contents, but it is significant that this study looked at how much graphics technologies are used in such news video contents.

최근 지상파 서비스에도 양방향 데이터방송 TV 서비스 기능이 본격화되면서 t-learning(TV learning) 콘텐츠 개발도 활성화 되고 있다. 학습자가 데이터방송을 통해 콘텐츠를 학습할 때, 적절한 시기에 적절한 상호작용이 활성화되어야 한다. 현재 제공되는 데이터방송은 VoD(Video on Demand)의 패키지 기반이기 때문에, 프로그램이 처음 시작한 시간에 의지한 상대적인 시간으로 재생되는 방식이다. 그러나 학습자가 t-learning 콘텐츠를 시청하는 시점이 다양하기 때문에 VoD 방송으로는 적절한 시점에 적절한 데이터를 제공하기 어려운 동기화 문제가 발생하게 된다. 본 논문에서는 학습자가 t-learning 콘텐츠의 어느 시점에 접근하더라도 적절한 시점에 학습자와 콘텐츠 간의 상호작용이 가능한 동기화 메커니즘을 제시한다.
