본 논문에서는 토픽 모델링 기반 TV 프로그램 유사 시청 사용자 그룹핑 및 이를 이용한 TV 프로그램 콘텐츠 추천 알고리듬을 제안하였다. 제안 기술은 토픽 모델링 기법 중 Latent Dirichlet Allocation(LDA) 방법을 이용하여 TV프로그램 시청 기록 내에서 은닉된 유사 사용자들을 그룹핑하고 이러한 유사 시청 사용자 그룹 정보를 이용하여 사용자에게 선호 TV 프로그램 콘텐츠를 자동으로 추천하는 알고리듬이다. 제안된 자동 추천 알고리듬의 성능평가를 위해 실제 TV 시청기록 데이터를 이용하여 훈련 기간과 검증 기간을 나누어 훈련 기간 동안 제안한 알고리듬을 이용하여 사용자 개인에 대한 추천 TV 프로그램 콘텐츠 목록을 생성하여 검증 기간 동안에 실제 추천된 TV프로그램을 얼마나 시청했는지를 측정하여 추천 정확도를 검증하였다.

디지털 TV가 2000년대의 주력으로 부상할 것임에는 이론의 여지가 없다 그런데, 디지털 TV가 시장에 진입하기도 전에 대화형 TV 기능을 추가하지 않으면 안될 것으로 보인다. 디지털 TV는 여전히 단방향 방송기술에 의존하지만, 인터넷 기술 발전으로 사용자는 양방향 서비스를 요구할 것이 분명하기 때문이다. 이미 선진 각국은 양방향 TV를 개발하기 위해 다양한 노력을 경주하고 있다. 그런데, 대화형 TV의 개념이 최근 출현했기 때문에 어떤 기술이 어느 방향으로 발전할지 예측하는 것이 사실상 거의 불가능하다. 기존의 TV 기술은 최소한 30년 이상 존속될 표준에 근거해서 개발되었지만, 하루가 다르게 변화하는 인터넷 기술 표준에 바탕을 두고 제품을 개발해야 하는 특성 때문에 기술개발이 더 어렵다고 할 수 있다. 이 논문은 급변하는 방송환경에 적응할 수 있는 대화형 TV의 개념과 모델을 소개한다.

Reportedly it says that 45% teenagers in the United State exchange the SMS with their friends during television watching. In other word TV viewing moulds the social community between audiences. In terms of social television it is all about interaction or communication technology relevant to TV watching as well as social behaviour. Besides it integrates voice communication, text chat, context awareness, TV recommendations, ratings, video conference and so forth. So far it approaches the conceptual stage or pilot production and remains more research and development. This study is to scrutinise whether the functionality of social TV enables to substitute for social activities of TV viewers or not.

This paper presents a signal processing IC for digital HDTV, which is designed to operate in bunt-in HDW or in HD-set-top Box. The chip supports de-multiplexing an ISO/IEC 13818-1 MPEG-2 TS stream. It decodes MPEG-2 MP@HL video bitstream, and provides high-quality scaled video for display on HDTV monitor. The chip consists of ARM7TDMI for TS-Demux, PCI interface, Audio interface, MPEG2 MP@HL video decoder Display processor, Graphic processor, Memory controller, Audio int3face, Smart Card interface and UART. It is fabricated using Sam sung's 0.18-um and the package of 492-pin BGA is used.

This study traces the growth and changes in the spatial distribution and characteristics of media cluster in Seoul by focusing on the co-evolution of film and TV production. To identify the spatial distribution and aggregation of film and broadcast TV production, we measure their spatial auto-correlation based on Moran's I and LISA, using the data from the Census on Establishments of the National Statistical Office. In addition, the eleven semi-structured interviews conducted with workers in the media industries, such as film crews and TV drama producers, help to clarify the complexity and dynamics of diverse factors that affect spatial distribution of media cluster. This multi-method study shows the increasing polycentricity of media cluster in the last decade. Gangnam, Mapo, Yeouido, Gangseo-Yeongdeungpo, and Seongsu have emerged as key hubs for media industries, particularly in light of changes in the transportation system and the real estate market. The finding indicates the co-evolution of film and broadcast TV production, demonstrating how the characteristics of the creative industry and metropolitan changes are intertwined with each other in shaping the geographical pattern of the media cluster.

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.

Based on the third-person effect hypothesis, this study conducted a nation-wide online survey to assess how Korean voters perceived the mass media's effect on the candidates' image and voting behavior during the 17th presidential election. The research results showed that the voters tended to perceive that the mass media such as newspaper, television and the Internet had a greater effect on others than on themselves with regards to the formation of the three candidates' images. The third-person effect on the voting behavior was also revealed differently in terms of the medium according to age and political tendency of the voters. For instance, the younger and liberal voters were likely to see newspaper as having a greater influence on other voters' choice of candidate, while the older voters saw TV as having a greater effect on other voters. The conservative tendency did not affect the perception of the voters at all. Another noteworthy result was that personal characteristics of the candidates' images such as appearances and communication skills did not affect the voters' behaviors in the election process.

Recently, the cosmetics industry considers male customers as a consumptive, active customer base who also have purchasing power with their stronger desire for their personal image enhancement. Male-preferred image brands have entered the era of unlimited competition through social media, thus increasing the acquisition of male beauty. Therefore, the information for designing favorable image strategies should be examined. This paper examines male awareness, determined by the degree of appearance management based on four categories (i.e., hair and skin care, makeup, foot and hand care, and plastic surgery). Based on the research, the paper proposes a data service to address the spatial and temporal separation problem between TV CF (the major media for recognizing information) and online $caf{\acute{e}}$/blog the major media for obtaining detailed information.
