The age of digital content mainstream consumers in the era of smart technology is expanding compared to the past. Consumers are taking a leading role in the production and distribution of contents in various forms. At the center of this is a post-modern social structure and space that break down the boundaries among Personal Digital Device, contents, production and consumption as a medium. Content rejects the existence of the same thing in the world. The tendency of the main consumer segment and the provision of post modern storytelling that penetrates it creates a huge industry group with various forms of contents. In order to carry out this study, with analyzing examples of movies, games, and advertisements, we found the fact that the center of content creation for individuals made their unique style, excluding generality. As a result of this research, the relationship between the user-driven digital contents and post modern storytelling have been revised the awareness about the possibility of various convergence in the field of contents production.

21C, Multiplex Cinema Theater is made from movie industry developed and become a place where we can spend our free time and consuming. But, theater users, who are many and unspecified persons, are short of information on the Multiplex Cinema Theater, so that they may be injured or killed at the occurrence of fire accident. Particularly, Multiplex Cinema Theater is a place that underground space or top floor in highrise building had many people in theaters. However, this problem is difficult to solve that to protect human being and properties at the occurrence of fire accident in the Multiplex Cinema Theater, In order to overcome such problems, Multiplex Cinema Theater need fire protection solutions facilities concerning particulars to pay attention to the safety on a fire and evacuation. This study analysed Multiplex Cinema Theater concept and computer simulation for risk point.

The technology and concept of multimedia expands with the rapid growth of Digital technology. Digital broadcasting has already begun and movie industry is also switching the way of visualization from analog to digital. Image compositing is the core of the computer graphics related multimedia technology. Currently, various computer graphic technologies are being developed. Nevertheless, image compositing are being done manually because of not only the expensiveness image compositing equipments, but also the lack of experts in this area. This paper present a new image compositing technique for 3-Dimensional graphics and digital sources. A 2-Dimensional subject which will be used as a background was expanded into a 3-Dimensional by using the tracking technique. Thereafter, Effective image compositing has been obtained by precisely cooperating digital source images and 3-Dimensional model using 3-Dimensional graphics editing tool.

Visual effect production by computer graphics techniques has become more important in these days. However, there are three problems in the domestic contents production environments. First of all, most Korean film companies have insufficient generally potential to maintain and support their R&D (Research and Development) teams. Secondly, they are much dependent on the abroad commercial software tools. Finally, many people have to participate in the image production pipeline, called the labor-intensive pipeline. In producing a demonstration work, "The Sixty -miles-an-hour man", we have evaluated the usefulness of the developed camera tracking and image composition methods and then examined various production consideration elements. In addition, in order to develop a productive technical element and write a competitive film script, mutual understanding between the developers and the production users should be achieved. Also, this paper describes a role of the technical supervisor to direct the production environment in detail.

In recent years, the VR-interactive action contents industry, which utilizes five senses of human bodies, has continued to grow through areas such as games, tourism, movies, performances and exhibitions, but it has reached to breaking point by unrealistic visual elements. Therefore, the purpose of this study is to analyze the effect of each evaluation factor based on visual immersion of interactive type of VR action contents to overcome the limitations. For this study, firstly, prior research is reviewed. Secondly, the evaluation factors of visual immersion of interactive type of VR action contents and hypothesis are to be derived. Research finding is that there is no difference to recognize proximity, three-dimensionality, visibility and immersion by gender. Also, in order to influence visual immersion, it is important that 3D modeling of characters and objects must be sophisticated to be fit in with their surroundings and lighting. This makes user to be confused where they are actually in.

Motion capture technology is widely used to make a realistic motion in these days. So, motion capture data is required to exchange between many animators in a work group. But different motion capture devices have different motion rapture data formats. Thus it is difficult that a animator reuse and exchange motion capture data in a storage. In this paper, we proposes a standard format for integrating a different motion capture data format. In addition, we proposes a framework of a system that manage motion capture data using our standard format. Our standard format is called MCML(Motion Capture Markup Language). It is a markup language for motion capture data and based on XML(extensable Markup Language). Our system to manage motion capture data consists of a several component - MCML Converter, MCML , MCML Editor, Motion Viewer.

Lately the National Technology Standard of IMT-2000 service in Korea was decided for both technology standards (cdma-2000, W-CDMA), and consequently the comprehensive countermeasures against the Technology Standards are all the more emphasized. Especially to private enterprises which were selected as service carriers for IMT-2000 service in Korea, making corresponding strategies in relation to both technology standards must be settled without delay. The Government also should serve the development of the I&T Industry through the various processes of adopting the policies and working out strategies In relation to Technology Standards of IMT-2000. Therefore in this paper, 1 would like to survey the features of both Technology Standards(cdma-2000, W-CDMA) and to propose the hereafter corresponding strategies in relation to IMT-2000 services.

The remarkable development of digital technologies and the success of 3D stereoscopic films have led to started drawing attention to stereoscopic images. The stereoscopic images have not become a passing fad in the present time unlike in the past, but have constantly showed their potentials. Unfortunately, the domestic stereoscopic images market is faced with difficulties, such as lack of the capital strength and of insufficient production infrastructure, and the production of 3D from 2D. As a result, it is not easy to produce creative stereoscopic animation contents. Therefore, in Korea, more efforts should be made in accumulating a plenty of data on production techniques. In order to make film production reflecting stereoscopy and effective stereoscopic implementation, which are necessary to produce high-quality stereoscopic contents, this thesis gave an explanation about a production technique studied on the basis of 3D graphic. Stereoscopic images are definitely one of the most promising image contents in the 21st digital contents industry. For the reason, in order to produce stereoscopic animation contents with high quality, fundamental studies on the stereoscopic images should be performed in a constant and cautions way.

3차원 영상 기술은 방송, 영화, 게임, 의료, 국방 등 다양한 기존 산업들과 융합하며 새로운 패러다임을 형성하고 있으며, 고품질 및 고해상도의 3차원 영상 획득에 대한 필요성이 강조되고 있다. 이에 따라, 최근에는 3차원 입체 영상을 제작 하는 방법 중 하나인 2D-plus-Depth 구조에 대한 연구가 활발히 진행되고 있다. 2D-plus-Depth 구조는 Charge-Coupled Device(CCD) 센서 등을 이용한 일반 카메라와 깊이 카메라를 결합한 형태로써 이 구조로부터 얻은 깊이 영상의 해상도를 상향 변환하기 위해서 Joint Bilateral Upsampling(JBU)[1], 컬러 영상의 정보를 활용한 보간법[2] 등의 방법들이 사용된다. 하지만 이 방법들은 깊이 영상을 높은 배율로 상향 변환할 경우 텍스처가 복사되거나 흐림 및 블록화 현상이 발생하는 문제점이 있다. 본 논문에서는 2D-plus-Depth 구조에서 얻은 고해상도 컬러 영상에서 보간 정보를 구하고 이 정보를 저해상도의 깊이 영상에 적용하여 상향 변환된 가이드 깊이 영상을 제작한다. 이 가이드 깊이 영상을 Bilateral Filtering[8]을 이용함으로써 고품질의 고해상도 깊이 영상을 획득한다. 실험 결과 제안하는 방법으로 해상도를 상향 변환을 할 경우에 기존의 보간법들에 비해 깊이 영상의 특성을 잘 보존함을 확인할 수 있고, 가이드 깊이 영상에 필터링을 처리한 결과가 JBU의 결과보다 향상됨을 확인할 수 있다.
