This study tried to anticipate the near future changes of domestic online video, music service and media usage through the status quo. The research group was focused on the twenties, University students because they are the active media contents users. It surveyed the students in Busan, and used the method of descriptive statistics analysis for the understanding of the present state and near future prospect. This study shows that almost half of them use both services, and three people out of ten are the heavy users who use the services for over 3 hours a week. The streaming method is higher proportion than download method in using type. They are getting accustomed to pay contents cost, but it couldn't be said the paying content cost has been established. Preferred contents genre appears to be the RMC(Ready Made Contents) such as existing broadcaster contents and movies. Notable result on media usage was the proportion of the so-called 'Zero-TV'. It was 32%, significantly higher than the proportion of the total population(4.4%). Integrating the analysis results, we can expect that the usage pattern will be changed gradually, thus the advent of various revenue models will emerge.

최근 온라인게임, e-Book, 모바일콘텐츠, 포털 등 IT 기반의 새로운 서비스 산업으로서 디지털콘텐츠 산업이 급성장하고 있다. 또한, 과거 엔터테인먼트 위주의 콘텐츠산업이 미래에는 제조, 서비스를 포함한 전 산업영역에 체화융합되어 확산되고, CT 및 IT 기반의 새로운 콘텐츠 산업이 급성장할 것으로 전망되는 등 융합형 콘텐츠에 대한 관심이 증대되고 있다. 정부에서도 신성장동력으로서의 융합형 콘텐츠 산업에 주목하여, 관련 산업을 발굴육성하는데 정책적 관심을 기울이고 있다. 기존의 콘텐츠 분류체계는 영화, 음악, 방송 등 장르 중심적이어서 관련 기술의 발전 및 융합현상을 제대로 반영하지 못하는 한계점을 가지고 있다. 따라서 미래 정책추진의 기반(base)로서 효과적으로 활용되고, 콘텐츠 분야의 외연확장을 포괄하는 새로운 분류체계(taxonomy)의 정립이 요구되는 상황이다. 이에 본 고에서는 미래 정책추진 및 산업활성화에 초점을 맞추어 기존 분류체계의 한계점을 극복하는 차세대 융합형 콘텐츠 산업에 대한 새로운 분류체계를 제시하고자 한다.

Differently from instruments which synthesized sounds and tones in the past, voice synthesis engine for music production has reached to the level of creating music as if actual artists were singing. It uses the samples of human voices naturally connected to the different levels of phoneme within the frequency range. Voice synthesis engine is not simply limited to the music production but it is changing cultural paradigm through the second creations of new music type including character music concerts, media productions, albums, and mobile services. Currently, voice synthesis engine technology makes it possible that users input pitch, lyrics, and musical expression parameters through the score editor and they mix and connect voice samples brought from the database to sing. New music types derived from such a development of computer music has sparked a big impact culturally. Accordingly, this paper attempts to examine the specific case studies and the synthesis technologies for users to understand the voice synthesis engine more easily, and it will contribute to their variety of music production.

오늘날 인터넷 상의 디지털 콘텐츠는 기하급수적으로 증가하여, 콘텐츠를 관리하기 위한 다양한 시스템과 관리 체계가 연구 개발되고 있다. 특히 2000 년대부터 식별체계에 대한 표준화 연구가 진행되면서 논문등의 문헌 정보와 음악, 영상 등의 콘텐츠에 식별 체계를 적용하고 관리하려는 연구가 활발히 진행중이다. 특히 국내에서는 정보통신부와 한국소프트웨어진흥원이 디지털콘텐츠 유통기반을 구축하기 위해 CONPIA.COM 사이트를 개발하였고, 2000 년 정보화지원사업으로 한국데이터베이스진흥센터에서 디지털콘텐츠 식별체계 사업을 진행하었다. 이후 2001 년 정보통신부가 한국전산원를 디지털콘텐츠 운영기관으로 지정하면서 확장개발 및 운영 시험 등 향후 서비스 운영에 대한 기술개발에 집중하고 있다. 이러한 시스템에 적용된 식별 체계는 체계적인 구문 구조를 가지고 있으며 구문구조에 맞는 식별 코드를 해석하여 디지털콘텐츠를 찾는 구조를 가진다. 그렇지만 기존의 시스템은 식별체계의 확장과 변화에 따라 시스템 인터페이스를 재설계하고 내부 처리 알고리즘을 수정해야 하는 등 많은 수정이 요구된다. 이에 본 논문에서는 DDDS 알고리즘을 적용하여 식별 코드를 해석하기 위한 시스템을 구성하고 사용자 인터페이스를 설계하였다.

This paper intends to propose a technology for recommending convergence/composite art playlist contents that are fused with tags suitable for the user's situational information and taste to users for non-face-to-face art appreciation education. For the implementation of the proposed technology, the characteristics of works of art are analyzed, and related music and works of art are matched based on the tags of the analyzed works. In addition, we would like to propose a technology that automatically creates content for fusion and complex art viewing playlists using matched works.

As digital content services, especially OTT(over-the-top) video services, diffuse rapidly, so do smartTVs. Based on the indirect network effect theory and the complementarity theory, this study explores the relationship between digital content services and smartTV. Using the Media panel dataset, this study analyzes how the usage of digital content service (OTT usage, OTT usage volume, the usage of various OTT service types, and online game/music/education/news service) affects smartTV usage. This study shows that OTT usage and its usage volume is positively associated with smartTV usage, and that the usage of various OTT service types is positively associated with smartTV usage compared with non-OTT users. As for online content services, the usage of online education service is positively associated with smartTV usage while the usage of online news service is associated negatively. These results support the indirect network effect theory and the complementarity theory.

The major purpose of this study is to examine the effects of customers' perceptions toward service quality of mobile music service on customer loyalty and switching intention. For this purpose, this study posited three service quality characteristics including interface, service, price quality as key determinants of customer loyalty and switching intention based on relevant literature reviews. A research model and hypotheses concerning the relationship between these variables were constructed. Moreover, this study explored the moderating effects of attractiveness of alternative and switching costs on the relationship between customer loyalty and switching intention. An online survey was administrated on 433 mobile music service users and a simple, multiple, and hierarchical regression analysis were employed. The results indicated that all of interface, service, price quality have significant positive influences on customer loyalty, and both of service quality and attractiveness of alternatives have influences on the switching intention in a positive way. On the other way, it was shown that switching costs have a negative influence on the switching intention. The moderating effect of attractiveness of alternatives on the relationship between customer loyalty and switching intention was also found. The implications of these results are discussed.
