The dissemination of smart devices has made a lot of changes in overall social activities. In particular, people use various types of smart devices in their spare time, such as watching video clips, but there is a lack of research on external factors influencing the attitude toward using such devices. Therefore, in this study, the effects of video viewing environmental factors (e.g. screen size and video length) and personal factors (e.g. gender and need for entertainment) on perceived ease of use, perceived usefulness, and attitude to use devices based on technology acceptance model. As a result of analyzing 660 users having different smart devices, the attitude to use smart devices is more positive as the screen size increases, but there is no difference according to gender. In addition, while the length of video clips does not affect the attitude to use, the need for entertainment positively affects the attitude to use. Based on the results of this study, we expect that it can be used for optimized customer marketing and management strategy that integrates product development and video content production in consideration of factors such as video viewing environmental factors and personal factors.

CAS used in IPTV or DTV has an environment of sending single type of contents through single streaming. But it can be improved to support users' various video applications through single streaming by combining with SVC. For such an environment, efficiency should be firstly considered, and hierarchical key management methods for billing policy by service levels should be applied. This study aims to look into considerations to apply SVC to CAS and propose SVC encryption in CAS environment. The security of the proposed scheme is based on the safety of CAS and oneway hash function. If the proposed scheme is applied, scalability can be efficiently provided even in the encrypted contents and it is possible to bill users according to picture quality. In addition, the test results show that SVC contents given by streaming service with the average less than 10%overhead can be safely protected against illegal uses.

본 연구는 디지털 TV의 다채널화와 관련하여 최근 사용편의성 문제가 중요하게 대두되고 있는 EPG(Electronc Program Guide)와 조작장치를 대상으로 사용자의 요구사항을 분석하고 그에 대한 해결 방안을 제시하고자 하였다. 디지털 방송이 국내에서는 아직 보편화되어 있지 않아 일본 동경 지역 SkyPerfecTV 가입자를 대상으로 다채널 TV 환경에서 디지털 STB(Set Top Box)의 사용실태를 조사하고 분석하였다. 그 결과 간편한 채널 이동 과 EPG 네비게이션 방식, 일대일 TV 환경도래와 개인별 선호 패턴의 극화 현상에 대응한 개인화된 시청환경, 광범위한 정보공간에 대해 제압감을 증강시킬 수 있는 정보표시 방법, 조작수를 줄이며 직접 조작감을 향상시킬 수 있는 입력장치 등에 대한 사용자 요구를 파악할 수 있었다. 이러한 조사결과를 바탕으로 본 연구에서는 “퍼스널 TV”라는 근미래형 인터랙션 스타일을 상정하고 가상 디지털 방송국(D/TV 시뮬레이터)을 기반으로 “퍼스널 컨트롤”과 “스마트 EPG”의 사용자 인터페이스를 개발하였다.

This study explores a value chain structure of TV program including news, drama, and comedy. The purpose of this research focused on factor analysis and the relationship among viewer's program selection motivations. This research explores correlation between personal value and viewing motivation. This study was to identify the value structure of respondent on TV program(news, drama, comedy) based on means-end chain theory. The research used structured APT laddering questions and 251 data was analysed. Through such analysis, category difference by stage and relationship difference were identified and hierarchical value map was compared. There are four different value ladders: first is attributes, functional consequences, psychological consequences, and final value. The result shows that on news program the basic function is viewers are want to visual factor and quickly acquire social news and they pursue a value of personal social relationship. Whereas, on drama program, the viewers are reflected by around person, and they selected a program based on closed related person. In addition, the viewers are influenced by program's social nomination, production's brand in drama, and performer's nomination, producer and program prominence on comedy. The program selection is highly correlated on program selection's credibility, vital energetic life, and social relationship. The results shows that there was no significant difference between low involvement group and high involvement group for main category involvement group respondents.

This study investigates the detrimental effect of watching sexual content in three-dimensional (3D) moving pictures. An increasing amount of investment is put especially in 3D adult content to boost their 3D media industries. It is crucial that the effect of sexual contents on viewers be identified. In this experiment, a between-subject design was employed to analyze various effect of sexual content on participants whether they viewed the same stimuli in 3D or in 2D. In particular, the presence scaling was used to evaluate how real the video clip is. In addition, the permissiveness toward sexual behaviors and the level of sexual arousal were measured to examine the different effect of sexual content by dividing two separate groups in 2D and 3D condition. The result shows that those who watched a 3D video clip perceived higher sense of presence compared to those who watched a 2D video clip. Furthermore, subjects in 3D condition reported lower scores of permissive attitude toward sexual behaviors. This confirms that 3D display delivers more visual experience and has an impact on people in terms of perceiving sexual contents and changing their attitudes towards sexual behaviors.

In this media convergence era when the 'hybrid' genres increase, it has been important to explore distinguishing genre-specific effects of contents use. This study revealed that news, current affairs/talk, and documentary genres respectively produces opposite directions of influences on values; likewise, drama and reality genres also respectively produces differentiated impact on values and social trust. Drama viewing itself shows contrary patterns on civic attitude, i. e., positive relationship with social trust while negative with tolerance.

최근 시작된 국내 디지털 지상파 방송으로 이제 본격적인 디지털 방송 시대가 열리게 되었다. 디지털 방송 서비스는 다매체, 다채널을 통한 방송 프로그램의 증가와 양방향 TV 방송 서비스로 인해 사용자에게 다양한 방송 프로그램의 선택과 개인별 맞춤형 시청 기회를 제공함으로써 새로운 방송 서비스 환경을 필요로 하게 되었다. 이에 본 논문에서는 맞춤형 DTV(Digital TV) 방송 서비스를 제공하기 위하여 TV-Anytime 영상 메타데이터에 대한 연속 데이터 마이닝 기법을 이용하여 시청 선호도 프로파일을 생성하는 효율적인 기법을 제안한다. 또한, 내장형 운영체제 기반의 사용자 디스플레이 모듈을 제공하며, 실험을 통하여 본 논문에서 제안하는 방법의 효율성을 고증한다.
