As a digital TV has outstanding features of being the most influential device in the living room and having the wide spectrum of users, several internet services has been ported on the digital TV platform (in the form of data services) in order to enhance their brand powers. Most of the services, however, failed to get a satisfactory results as the data services are defeated by the broadcasting contents in the competition for the viewer's interests. In the paper, the design guidelines that make data services not to compete with the broadcasting contents are proposed and a prototype of a data service that accommodates the guidelines is introduced.

In 2013 the Netflix, an OTT in USA, launched all at once 13 episodes of the House of Cards season. Binge-watching is the word which means watching continuously 2~6 episodes of a TV program with one sitting, the new normal of TV watching behavior, cultural and social currents all over the world. This study has analyzed the factors and motivations which affect to the persistent intention to use binge-watching. It conducted an online survey from 333 Quota sample from Korean age groups between 20th~60th with 81 questionnaires. The 5 groups were induced as motivation factors to binge-watching. The 3 groups which consisted of , , are affecting as positive to intention to use binge-watching. But the other 2 groups which are and doing as negative. The survey has shown that the persistent intention to binge-watching is affected by ages more younger, whom doing binge watching more frequently, whom estimating more higher to the conceived usefulness to use. As a theoretical model, expanded technology acceptance model was adopted and US drama House of Cards. This study could promote the next generation contents planning and S-VOD service industry.

This study is a case study on investigating students' learning behavior in the online English reading class of an on-off course. For this purpose, a survey was conducted on a total of 77 students from an English listening and reading course and phone interview with 5 students was implemented. The findings revealed that regularity of learning interval and learning sequence need to be improved through student management in order to increase the effect of online learning. In case of lecture watching, the students are good at utilizing the strengths of taped lecture, such as using pause and repeating watching. However, more research need to be done on how to develop online lecture to enhance students' understanding of the lecture. Regarding the offline review quiz that is supposed to stimulate students into their more positive watching of the lecture, it is suggested that a few of its related elements such as the online learning period and the number of quiz questions be corrected for its better effect.

This study focuses on the fact that a OTT service is vigorously used for smart phones, and suggests a design of method to trace the experiences of watching television contents. For this purpose, we developed logging functions and embedded them into existing OTT service application to record flow and pattern of watching context. This paper suggests a log file format which can accurately and precisely record watching actions of users per-second methodology rather than former per-minute methodology. Moreover, this study shows that the application can trace watching attitude according to occurring events by characteristics and playing modes of realtime broadcasting, VOD, advertisement contents. In addition, based on the result of the study, this paper discusses educational, operational meaning of the method such as methodological application in mobile ethnography field or survey for total screening rate.

최근 화두가 되고 있는 스마트 폰 앱의 관심으로 스마트 TV의 앱에 대한 관심도 함께 증가하고 있다. TV시청 이용자들의 편의를 위해 증가하고 있는 수많은 채널과 콘텐츠 중, 개인 사용자의 이용 습관 및 대중의 선호 프로그램을 고려하여, 편리하게 원하는 TV프로그램에 접근하도록 해 주는 TV 앱이 있다면 이는 매우 중요한 기능으로 자리 잡을 가능성이 높을 것으로 예상된다. 이에 본 논문은 사용자의 시청 이용행태를 기반으로 주제모델링 기술의 고전적 모델인 LDA을 기반으로 협업필터링을 결합한 TV 선호 프로그램 추천 알고리듬을 제안한다. 개인의 관심 선호도는 일반적으로 특정 개수로 한정지어지는 특성을 고려하여, 개인 선호도 특성이 구별 되도록 두 가지 방법을 적용하였다. 하나는 개인 선호도 프로파일의 특정 상위 주제만을 고려하는 것이고, 또 다른 하나는 개인별 주제에 대한 선호도의 다양성이 드러나도록 비대칭 하이퍼-파라미터를 갖는 LDA를 사용 하였다. 실험 결과, 두 가지 방식에 대해 사용자의 실제 TV시청 이용내역 데이터를 기반으로 추천 성능의 향상을 평균 Precision 값을 측정하여 확인하였다. 또한, 본 논문에서는 주제 모델링을 통해 학습된 각 주제의 상위 확률의 TV 프로그램들을 분석한 결과, 하나의 주제가 개인별 시청의 특성 보다는 가족단위의 시청 특성을 드러냄을 확인할 수 있었다.

사용자들이 직접적으로 영상의 전송과 시청 과정에 참여하고, 그 과정에서 다양한 형태로 상호작용을 할 수 있는 새로운 형태의 미디어 서비스를 인터랙티브 미디어 서비스(Interactive media service: IMS)이라고 한다. 본 연구의 목적은 이러한 인터랙티브 미디어 서비스 사용에 영향을 미치는 요인을 규명하는 것이다. 이를 위해 현재 서비스되고 있는 다양한 형태의 인터넷 미디어 서비스 사용자 12명을 대상으로 한 인터뷰를 진행하였으며 근거 이론 분석법에 따라 이를 분석하였다. 그리고 분석 결과에 따라 도출된 요인들을 바탕으로 인터랙티브 미디어 서비스 사용과 관련한 이론적 틀을 제시하고 이를 검증하기 위한 웹서베이를 실시하였다. 연구 결과, 시스템의 기술적 구조, 커뮤니케이션 맥락, 콘텐츠 특성과 같은 요인들이 인터랙티브 미디어 서비스 사용에 영향을 미치는 것으로 나타났다. 특히 실시간 인터랙티브 미디어 서비스의 경우에는 커뮤니케이션 맥락에 따른 사용 행태가 더 민감하게 나타났고, 비실시간 인터랙티브 미디어 서비스에서는 시스템의 기술적 특성과 콘텐츠 특성에 따른 사용 행태가 보다 민감한 것으로 나타났는데, 이는 인터랙티브 미디어 서비스의 시간 유연성(timing flexibility)에 따라서 사용 행태에 영향을 미치는 요인이 달라질 수 있음을 의미한다.

Hana TV and Mega TV have been growing rapidly with IP-VOD service. The number of subscribers of both of them were 1.4 million in April 2008. Additionally, the change of viewing patterns of IPTV subscribers was predicted. Therefore, the purpose of this paper is to see how the subscribers use IP-VOD service practically. For this research, the frequency, the time and the duration of connection by genre have been analyzed on the March of 2007 and 2008. According to the result, there was a significant change quantitatively: within a year, not only the number of subscribers has doubled, but also the frequency of monthly connection has been increased 15 times. In addition, the duration of viewing per person has quadrupled. Regarding to the contents, the subscribers still prefer to watch free TV programs. However, the viewers have their own way of consuming TV programs. It has been proved that IPTV is a complementary media of free TV with a strong possibility to change the viewing patterns in the near future.

본 연구는 N스크린 서비스의 유료이용자와 무료이용자 간의 이용행태와 삶의 만족도를 비교 분석하였다. 그 결과, 두 집단간 방송 프로그램을 시청할 때 다양한 디바이스를 통해 연계 이용하는 행위는 통계적으로 유의미한 결과를 나타냈으며, 무료이용자가 더 많은 디바이스를 통해 연계이용을 하고 있음을 밝혀냈다. 또한, 개인적 만족도는 유료이용자가 더 높게 나타났으며 통계적으로 유의미한 결과를 나타내었다. 마지막으로 동영상 콘텐츠를 유료로 지출하는 행위는 개인적 삶의 만족도에 부정적인 영향을 미쳤으며, 방송 콘텐츠를 유료로 지출하는 행위는 관계적, 집단적 삶의 만족도에 정적인 영향을 미치는 것으로 나타났다. 본 연구를 통해 N스크린 서비스 이용자의 이용행태에 맞춤형 서비스를 제공, 사업자의 비즈니스 모델을 모색하는데 도움이 될 것이라 판단된다.

In multi-media, multi-channel era, video viewing using various digital devices via the Internet, not the existing broadcasting network, is emerging as a new broadcasting viewing behavior. OTT service is regarded as the main service of this change of viewing behavior. It is a video service that can seamlessly use any content desired by the user at any time, at any time, any device, any contents, if the Internet connection is available. The purpose of this study is to investigate the factors affecting the satisfaction of OTT service by applying the technology acceptance model (TAM). As a result of analyzing through 303 questionnaires of the early users of OTT service, social pressure, perceived popularity, perceived cost, user reputation, individual innovation, and esthetics set as external factors in this study are partially affects perceived usefulness, perceived ease of use, and perceived enjoyment. In addition, perceived usefulness, ease of use, and enjoyment are directly influencing satisfaction. Based on these results, we discuss the theoretical and practical implications and propose future research direction.
