본 논문은 시청자가 TV를 시청하다가 마음에 드는 화면이 있으면, 이를 캡춰해서 친구들에게 메시지로 보내는 서비스를 구현하는 방법을 기술한다. 이를 위해서는 셋톱박스에서 실행되는 Xlet 애플리케이션에서 비디오 스트림의 특정화면을 캡춰할 수 있어야 하는데, 현재 미들웨어는 이런 기능을 제공하고 있지 않다. 따라서, 본 논문에서는 Xlet application 에서 시청자가 지정한 화면의 시점값을 방송국 서버로 전송하고, 서버에서 해당 화면을 캡춰하여 이를 시청자가 원하는 수신자에게 보내주는 방법을 사용한다. 미들웨어 API 표준에서 현재의 NPT (Normal Play Time) 을 알려주는 API 를 제공하므로, 애플리케이션에서 시청자가 원하는 시점의 NPT 를 구해 이를 방송국 서버로 보내고, 서버에서는 이 NPT 에 해당되는 동영상의 미디어 타임을 구해, 그 시간에 해당되는 프레임을 계산하여 화면을 캡춰한다. 본 기술을 활용하면 서버에서 캡춰된 화면을 Mobile, Web 등의 매체에도 전송할 수 있으므로 유무선통합, 방통융합형 서비스로 확장해 나갈 수 있다.

The purpose of this study is to be aware of the relationship between the perceived risk and purchasing intention after investing the impacts by 3 factors-consumer, media, and product characteristics on the perceived risk. The influence on perceived risk is categorized based on the 3 factors' combinations. The result of this study shows that the each characteristics of media, consumer, and product affect consumer's perceived risk and also this risk is affected by the relationship among these 3 independent variables. These results mean that the consumer's perceived risk about buying goods at the internet shopping mall or TV home shopping cannot be measured by a single dimension. Finally, it has a negative relationship between the perceived risk and purchasing intention. Implications for managers' use of shopping media are discussed in terms of the product and media characteristics fit.

The candle rally against the import of American beef which lasted for a long time was full of various types of social movement. That is, new media including mobile phone, Internet, Internet cafes played an important role in mobilizing people around the rally. Thus, this research focuses on the meaning and effect of these kinds of movement. In particular, it analyzed the possibility of real time broadcasting through the Internet as civic journalism, which received much attention in the rally. For this, this research used case study and interview as main research method. Case study focused on Internet cafes based on the media coverage of the rally. Interviews were conducted with workers at OhmyTV, Color TV, and 615TV. These workers at progressive media emphasized on the scene coverage as the advantage of real time delivery. Transmitting many citizens' voices was another advantage. It is expected that personal media and progressive media which try to show the scent as it is will play an important role in the future journalism with the expansion of Wibro.

In this paper, we present a design and implementation of a TV-Anytime metadata authoring tool for providing personalized data-broadcasting services. The TV-Anytime specifies metadata schema, metadata coding and delivery, and provides service models to provide personalized broadcasting content services at anytime when users want to consume using metadata including ECG (Electronic Content Guide) and content descriptive information in a PDR (Personal Digital Recorder)-centric environment. In spite of a useful services based on TV-anytime metadata, the metadata authoring still remains as a harassing and time consuming task. For easy metadata authoring, the proposed metadata authoring provides the following key functionalities: metadata visualization, media access, and semi-automatic method for editing segment related metadata.

스마트 폰의 선풍적인 인기에 힘입어 TV 산업에서도 스마트TV가 출현해 시장 영역을 넓히고 있다. 이에 따라 TV 리모컨 또한 새로운 방식의 유저 인터페이스를 지원하는 하나의 스마트 리모컨으로 업그레이드 되고 있으며, 스마트 리모컨을 통한 홈 멀티미디어 디바이스의 통합 제어와 미디어 공유에 대한 여러 가지 시도가 이루어지고 있다. 이에 본 논문은 DLNA 환경 속 스마트 리모컨과 TV 디바이스의 역할에 대해 재 정의하고, 이를 기반으로 DLNA 및 UPnP 디바이스 아키텍처에 제시된 컨트롤 포인트와 디바이스 간 제어 및 미디어 공유 절차에 따라 스마트 리모컨을 통한 TV의 제어 기법을 제안한다. 제안된 스마트 리모컨을 통한 TV의 제어는, 크게 사용자와 무관한 백그라운드 스레드로 처리될 제어 준비 단계와 사용자의 입력을 통해 실질적인 제어를 수행하는 제어 단계로 나뉘고, 각각의 단계에 해당하는 UPnP 미디어 네트워크 단계에 맞춰 진행된다. 제안된 DLNA 환경 속 TV 제어 방법의 구현을 위해서는 선행적으로 TV OSD 제어를 위한 코드에 연동해 TV 디바이스 서비스 서술자의 확장이 이루어져야 할 것이다.

The aim of the this study is to observer paradoxal phenomenon in media election. The media, especially Television, was traditionally a journalistic operation representing political events on the outside of political camp. But recently, it intervenes to 'the political camp' as the most important method for election campaign. A centripetal of electronic medias making the dominant political space offer an alternative plan which get over the modern crisis of representative democracy. Even though, to the production of the political symbol and the operation of symbol which constitute substantial system of political action, the human being subject is excluded and the technical system of communication make up a govern structure. So it makes the contradictory situation. TV broadcast for election campaigning show well this paradoxal situation. The institutionalization of electoral broadcasting oriented by the State strengthens an immensification, an economical and political efficiency and a transparency of electoral campaign. But the means which controls the mind of public is also strengthened. It relates the production and circulation of the political symbol and the symbolic image restricted by dominator. In conclusion, this study argues that the media election is institutionalized by the instrumental reason(procedural rationality of politics and technological rationality of broadcasting), therefore the candidate take a fragment roles for the production of transcendental political symbol and the voters accommodate to the symbolic images which are foreseen and they judge.

In addition to awareness building, TV media creates search behavior for the brand and the search result may link to a brand homepage and/or an e-commerce site. This study analyzed the impact of TV advertisements on a search volume at NAVER, a leading Korean search platform, in order to verify the impact of TV advertisements on brand-related search behavior. Results are as follows. TV advertisement exposure was significantly related to the amount of Korean search, English search, and total search. In addition, changes in TV advertising exposure also had a significant static influence on changes in search volume. The increase in the number of brand search was different by industries that carried out TV advertisements, and it was verified that the frequency of English searches increased faster than the frequency of Korean search as the exposure of TV advertisements increased. Therefore, domestic TV advertising volume has been verified to affect NAVER search volume, and the advertising industry and brand search language that conducted TV advertisements have been verified to be moderating variables. TV advertisements can be interpreted to cause brand search behavior in English even though it is not a native language for Koreans.

As information technology rapidly develops and the period required to enter new technology shortens, there emerges a wide variety of alternatives for consumers. When there are many alternatives in the market, users choose after making comparisons. This process of making comparisons is our research key. We established a research model to find a mixed effect that comes from new attitudes to technology adoption and alternative's continuous usage intention. The effect is revealed through a relative attractiveness (RA) factor to explain a user's process of comparison. We empirically test our research model in the new media services, such as mobile TV, web TV, and mobile IPTV. According to our research results, a continuous usage intention of an existing technology is an important factor to explain the adoption of a new technology. So, the contribution of our research is in finding a role for the RA factor in research in new technology adoption.
