Traditional broadcasting environment is merged with various interactive broadcasting services, and the users use these services through Set-Top-Boxes. But they have limited user interfaces, which are not suitable for TV environments by adopting internet formats. Therefore, this paper suggests a User Navigating Interface which helps the audiences to select and watch their favorite channels more effectively. Firstly, this paper analyzes EPG interface - the most basic service in interactive broadcasting. Secondly, it suggests a user interface and service structure suitable in the network-integrated TV environment.

In this paper, a face detection method for interactive TV control system using a new feature, edge histogram feature, with a support vector machine(SVM) in the near-infrared(NIR) images is proposed. The edge histogram feature is extracted using 16-directional edge intensity and a histogram. Compared to the previous method using local binary pattern(LBP) feature, the proposed method using edge histogram feature has better performance in both smaller feature size and lower equal error rate(EER) for face detection experiments in NIR databases.

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. 그리고 세계 각국의 개발 동향을 아울러 살펴보기로 한다.

Movie Films and Games, to be close to their industries, needs in crossover fields, are affected to each other. Interactive movie is an effective authoring method accommodating this trend on demands. However, studies which explore and examine various forms of Interactive effected films and storytelling approaches are scarce. This call for elucidation is basis of this research which applies the notion of Interactive movies and games to analyzing of trends and composition limits of Interactive movies, and improvised methodology of ability on merits for the next generation media cultures.

In this paper, we present an interactive data broadcasting system compliant with the Advanced Television Systems Committee (ATSC) standards. The proposed system provides users not only with various data broadcasting services but also remote interactive services. For various data broadcasting services, we have adopted a synchronized data injector that calculates the transmission time of synchronized data accurately and multiplexes synchronized data with the data of an MPEG-2 audio-visual program according to the calculated transmission time. To support remote interactive services, we designed and implemented a return channel server connected on a bi-directional interaction channel. Test results show that the proposed system provides both an asynchronous and synchronized data broadcasting service and remote interactive service appropriately.

The purpose of this study was to explore the effect of the interactive message expression and consumer characteristic insert IPTV advertising. The results of this study were follow: Firstly, Attention and attitude of interactive message advertising appeared than general TV advertising so that it was high. Second, In case of interactive message advertising, It appeared efficiently than the advertising without the advertisement detail information which is putting the good detail information. Third, In interactive message expression of IPTV advertising, Floating expression strategy appeared efficiently most. Lastly, Adoption of consumer characteristic was revealed that we had an influence on the knowledge level and the information search intention about IPTV. We present theoretical basis which to present interactive message to IPTV supplier is efficient, and the plan which floating expression can make the click intention of the advertising.

With the help of information technology, PVR has been evaluated as an innovative device that brings epochal changes for program selection and convenience of receivers with the convergence between broadcasting and telecommunication. Satellite broadcasters introduced PVR service to strengthen its interactive function. This study analyzed PVR user behavior and how it changed the existing TV viewing behavior through satellite subscribers. The results revealed that PVR subscribers mainly used it for time shifting like VCR use. FUrthermore, heavy PVR users watched TV more than on average and enjoyed a divers genre of programs. This study provides scholarly implication for PVR using behavior and its effects and its useful information for contents and marketing strategy to help PVR service popularization.

The object of study is to compare the characteristics of IPTV (Internet protocol television) subscribers and digital CATV (Community antenna television) subscribers. We used the adjusted residuals. We did gang survey for 100 subscribers in Seoul, Kyeonggi or Incheon regions. Compared to digital CATV, IPTV seems to have appropriate contents for interactive services and high satisfaction level for cost, but high dissatisfaction level for channels. Digital CATV subscribers would know and subscribe passively, compared to IPTV subscribers. IPTV subscribers are more satisfied than digital CATV subscribers even though IPTV is higher cost. Main content of digital CATV is sports, which is not interactive contents. People think IPTV is an innovative service which let subscribers see wanted contents always, but digital CATV is an extension of CATV. So digital CATV cannot use advantages of interactive services. Even though two services are almost same, they are very different in recognition.
