This paper summarizes the characters of virtual reality contents and its design problems, and suggests user centered approach in design methodology of VR contents. Based on case study of former VR contents design project, I developed a new VR contents design process in experience design perspective. This design process was applied on Tangible Space Initiative project of KIST, which showed positive roles of this design process as a dear communication media between project players, and an active generator of user-centered interaction design.

Information Centric Networking is changing the way how content is being transmitted. The shift from IP and host based networking towards content based networking scenario is growing day by day. Many researches have been done about different frameworks of ICN. Caching is an important part of ICN and many researchers have also proposed different ways for caching the data. With caching of data in intermediate devices like the network devices as well the user devices in some cases, the issue of content security as well as the role of the content producer becomes a major concern. A modified ICN architecture based on the current Content Centric Networking (CCN) model is presented in the paper. The architecture mainly focuses on involving the content producer in content delivery in the real time. The proposed architecture provides better security aspects for the CCN architecture. Apart from security the paper will also consider the issue of applicability of CCN architecture to replace the TCP/IP based architecture. The efficiency of the proposed architecture is compared with the previous CCN architecture based on the response time for a content delivery which shows very comparable level of efficiency. The paper than analyzes different beneficial aspects of the proposed architecture over the current architecture.

This study focuses on the phenomenon that K-POP has become spotlight as killer contents which can be spread over the world beyond Asia. In order to identify critical factors of successful impact of K-POP on other cultures, the influence of the change in media on the globalization of popular culture was explored and the related requirements were analyzed. Furthermore, the potential markers for K-POP, a core field of the Korean Wave, were also analyzed and specific factors such as effective infrastructure of among producer of contents, platform subscriber, network provider, terminal enterprise and retailers for building new businesses model were investigated in detail.

Channel of distribution of contents of digitalised multimedia contents is changing in form passed directly to consumer from manufacturer through digital network of high speed. Together, diffusion of various digital equipment that do is changing Past multimedia consumption structure with the wonderful speed so that can consume easily digital contents. Specially, Multimedia Personal Computer and fast diffusion of a digital television are acting role such as catalyst that promote easy purchase and consumption of multimedia contents of good qualify. However, this system is no method that can sell digital contents and express right that original owner for the contents can insist nothing but consume. Because consumer can distribute to another person copying contents that buy because of and user can distribute producing ashes again according to necessary field by oneself as well as, can lose meaning for original contents. In this paper, Text editing system for XrML (extensible Rights Markup Language) that describe about integrity of message and entity authentication in addition to necessary rights, fees, condition etc. and this to do fetters XML (eXtensible Markup Language) for copyright protection for digital contents in treatise that see hereupon and use digital contents design and embody.

In this paper, we have designed and implemented an E-Book Exchange System which is based on the Open E-Book Exchange protocol of Open E-book forum. The ebook is described digital contents composed of variable media and should require secured ebook server for copyright guarantee. Also, contents manufactures, circulation company, and user must access the ebook contents easily. So, Linux-based ebook server and reader can satisfy this requirements. Therefore, this research has developed Linux-based ebook server and reader which is cost-effective.

As digital contents circulation environment goes on-line by fast development of the latest Internet, contents demand is growing rapidly. However, XrML hard to change dynamically and has controversial point that hard to reflect user's request maximum after create license and issues to user, in this paper study of active digital license administration model who can reflect user request dynamically and support reusability of license XrML eXrML model who design extension design and suggested. Expect that this presents efficient administration plan in administration study of license base as well as study for digital contents administration.

DRM(Digital Right Management), which realize the controllability of intellectual right in the process of transactions with economically feasible cost, may cause critical changes in the distributions of digital contents. This Paper takes notice of the concept of 'Super Distribution' in which every user can be the core of the distribution and the possibility of usingvarious price structures by introducing DRM. We reviews that Super Distribution can increase the demand of digital contents by decreasing the information cost in the user aspect, and it can also diminish the distribution cost dramatically in the provider aspect. Also, DRM may allow various types of pricing which use different criteria such as the number or duration of usage. The variety in price structure can increase not only the profit of provider but the utility of consumer. These characteristics of DRM, as a whole, increase the efficiency of distribution and make the providers differentiate their services.

UCC is a key characteristic of so-called Web 2.0 which encourage the publishing of one's own content and commenting on other people's. Nowadays, UCC has become a widely used. Accordingly, problem of copyright become a issue. In this paper, we propose the DRM system for UCC rights protection. The system solve the copyright problem in UCC. Therefore, UCC creator can exert the right of UCC. In addition, if the problem of copyright occur, we can find the illegal user and call a him to account by CE information which is stored in UCC server and have a property that a manufacture of original contents can control the copyright.

다양한 장르의 비디오 데이터에서 하이라이트를 생성하는 것은 짧게 요약된 하이라이트 비디오 신을 생성하고자 하는 멀티미디어 컨텐츠의 제작자나 사용자에게 중요한 역할을 제공한다. 본 논문에서는 새로운 비디오 하이라이트의 생성 방법과 내용 기반, 즉 이벤트 기반의 비디오 인덱싱 방법을 제시한다. 경기 종목으로는 골을 넣어 득점하는 축구, 농구 그리고 핸드볼을 대상으로 하였으며 골을 넣어 득점하는 하이라이트 샷을 추출하기 위해 이벤트 규칙을 사용하였다. 비디오 인덱싱에서는 비디오 데이터 자체의 시각적 정보와 캡션 정보를 모두 이용하였다.

본 논문에서는 이미 만들어진 원본 시나리오에 따라 3D 모델들을 합성시키는데 목적을 두었을 뿐만 아니라, 사용자의 다양한 파생 컨텐츠 요구에 대응하기 위해 기존의 시스템과 달리 제작자가 아닌 일반 사용자가 원본 시나리오에 존재하는 3D 객체들을 재사용하여 원하는 시나리오를 다양하게 생성해 낼 수 있는 3D 객체 기반의 재사용 서비스 시스템을 설계하고 구현하였다.
