This study tried to examine the validity of the technical and institutional method to perform the purpose of public interest in terrestrial broadcasting. For this purpose, this study concentrated to the rate of direct reception of the terrestrial broadcasting that government and broadcasting company have offered since the digital transition. Results of analysis, it appeared that have not possibility of realization to set the direct receiving antenna and built-in Antenna for enhanced reception of the signal of the terrestrial broadcasting. Second, the MMS, if not enhanced the direct reception, was expected that repeated the retransmission through the pay broadcasting as the time of digital transition. Finally, the disaster broadcast was revealed that reduce the effectiveness of the UHD TV policy because of the mutual interference between frequencies and the incomplete solution of shadow area. According to these results, it is expected to be difficult for a while to perform the purpose of public interest in UHD TV.

Due to the advance of broadband communication networks including the Internet, the release of diverse media, and the busy life cycle of modern people, it became difficult to watch TV programs strictly according to the program schedule. Instead, demand to download and watch the programs at any time on TV is increasing. In order to meet the demand, terrestrial DTV broadcasters developed a TV service which provides various on-demand contents by integrating terrestrial DTV network and the Internet without enforcing viewers to subscribe broadcasting services such as IPTV or CableTV, and standardized it as OHTV(Open Hybrid TV). In this paper, we explain the current status of OHTV standard and worldwide hybrid TV services and their technical standards. We also provide a strategy for the next version of OHTV standard in order to enhance the value of OHTV.

In this paper, a reception rate of terrestrial digital TV broadcasting service is analyzed and a novel method which can estimate the broadcasting coverage rate more objectively and reliably than the existing method is proposed. Previous method measures the reception rate by means of electric field intensity measurement or subjective video quality assessment. Because of limited measuring points, it inherently has measurement error and cannot consider the viewer's receiving conditions in real-time. In order to consider the viewer's population and receiving environment, morphology which characterizes the viewer's receiving environment is extracted using household census data of National Statistical Office and the land cover map of Ministry of Environment. Using the extracted geographical morphology, the reception rate of terrestrial digital TV broadcasting service is calculated with Spectrum Management Intelligence System (SMIs). Proposed method can calculate the reception rate more objectively and reliably than the existing methods because it fully considers the viewer's receiving environments in real-time.

The 8-VSB modulation technology developed by ATSC was adapted for national terrestrial DTV broadcasting. It uses same bandwidth of 6㎒ as the one of NTSC TV broadcasting. The simulcast on the both of analog and digital is mandated for some period, some shortage within the limited frequency resource . ATSC transmission technology is excellent in long distance broadcasting, but it is even poorer than other transmission technology In mobile receiving. The design of transmission system in the ATSC broadcasting is food enough with the provision of wide area service without Interference from adjacent channel. To provide adequate DTV service within the broadcasting area, transmission technology is an important factor

This paper investigates audience perception on news content through comparison analysis on Comprehensive Programming Channels, TV chosun, JTBC, Channel A, and Terrestrial Broadcasting 'KBS'. How sensationalism created by video news affect audiences' credibility on news and media. The results shows that Comprehensive programming channels are assessed more sensational than terrestrial broadcasters by audience. Additionally, Comprehensive programming channels are assessed to get a lower credibility than terrestrial broadcasters by audience in the analysis of news and media credibility, comprehensive programming channels and terrestrial broadcasters. As a result, comprehensive programming channels showed lower news credibility and media credibility compared to that of the terrestrial broadcasters. This means that comprehensive programming channels must do the best not only recovering credibility from audiences but also constructing position as national broadcasting media.

In this paper we proposed channel models for terrestrial ATSC (Advanced Television Systems Committee) DTV (Digital Television) system in South Korea. For the purpose of this model, we research on propagation model involved in terrestrial DTV system and analyze out field test data of terrestrial DTV broadcasting carried out in korean Broadcasting System. Using the measured values of received field strength, newly proposed Path-loss models have more correctly than that of conventional Path-loss models. This models can be utilized usefully for the efficient ATSC DTV system implementation requiring accurate link-budget calculation

Korean TV program market has started since 1995 along with Cable TV and local TV stations and increased significantly due to Korean wave. Now the new platform such as IPTV makes a new opportunity of growth to the TV program market. This study will analyse the actual status and mechanism of Korean TV program market. To begin, Korean TV market is still dominated by terrestrial TV in domestic distribution market and in exportation even though the windows are diversified. This has influenced not only for the production market but also the distribution market as the following: continuous conflicts between terrestrial TV and independent production companies even though the significant increase of independent production in quantity ; terrestrial TV's dominance in distribution market with enormous libraries as for the major content provider. In addition, there are limited independent distributors due to the exclusive trade of TV programs by terrestrial TV. As for the exportation, foreign market for Korean TV programs are mainly Asian countries like Japan, China, etc. Furthermore, since the genre of distribution has been concentrated in dramas, it is time to make efforts to find a solution. Thus, this research can give a guideline as for the first step.

Since the 1960s in Korea, major broadcasting channels broadcasted farm television programs, however, airing of these programs were reduced in the 1990s. This was due to the declining number of farmers, and the low popularity rating of farm television programs. To cope with the situation, agriculture businessmen, farmers, and the officials concerned tried to acquire the independent farming television channel in cable television and satellite television, In 1998, one cable television channel started broadcasting, while another channel in satellite television began its broadcasting in 2001. One of the major concerns of the people in the broadcasting was actualization of the public interests in the new media multi-channel age. Recognizing this point, the study explored a few areas of concern such as conceptualizations of the public interest of the people in the digital age, examination of the surroundings of program production and marketing, and survey the media use behavior of target audience - rural residents; In the concept of the public interest, there are two points of view; market focused and democratic principle oriented. As the digitalization of broadcast advances and the logic of economics prevails, it is difficult to offer the public broadcasting service to farmers, however, democratic principles should be more emphasized. The rural resident prefer major terrestrial television channel to cable television and satellite television channel, and in media use behavior, the medium of major terrestrial television would be more useful for farm broadcasting.

This study investigated the television (TV) content viewers' behavior influenced by online communication at the choice of new TV series on a terrestrial streaming platform. For exploring the impact of the anchoring effect on the TV content consumption, this study analyzed the correlation between the first episode's TV ratings and the data of online comments or reactions. These data were potential audiences' communication, which were generated on the online article three weeks before the first broadcasting began. To avoid the crucial influence by external factors, such as season and social issue, the test was done with eight (8) TV series which have same genre (drama), similar core audience targeting (20-49's women), similar broadcasting period (Jun-Oct 2016), same scheduling (10.00 to 11.00 pm, weekdays) and aired on terrestrial TV platforms. This research found that not only the amount of comments and reactions, but also the attitude about the comments created before broadcasting, positively influence the audiences' decision-making behavior for new TV content choices. This investigation contributes to the literature on media economics and management by exploring the media content users' consuming behavior with behavioral economics perspectives (anchoring effect) and making a first step for finding a new effect on the media content consumption.
