A new approach to design of a discrete-time robust $H_{\infty}$ filter in finite horizon case is proposed. It is shown that robust $H_{\infty}$ filtering problem can be cast into the minimization problem of an indefinite quadratic form, which can be solved by implementing the Kalman filter defined in Krein space. The proposed filter is readily derived by simply augmenting the state space model and has the robustness property against the parameter uncertainties of a given system.

In this paper, we suggest a new video coding method using hierarchical block mode structure extension. It is based on the conventional H.264 block modes but adds hierarchically extended block modes to cover large resolution sequences. It is shown by experimental results that the proposed method can achieve a higher coding gain for HD sequences.

As multimedia content technology developed, there are many cases that service contents are being provided in many different ways in the cloud-based media service system. A DRM is a technology that can enhance the copyright of the digital content by providing right information. It is available on a single platform and has a problem that the additional cost when the platform is changing. In this paper, we propose a media service system based on cloud computing. It can be used on multiple platforms at the same time by applying a number of DRM for digital contents, and allows use of a new authentication for another platform without any additional cost.

Digital media was realized by two-dimensional design backup. But, digital medium decides form of architecture, and act as a design tool that can expand area of thinking. With such social change, investigate for digital architecture. And, wish to analyze design process of digital architecture and search the characteristics. Through comparison of digital and analogue, clear up that the digital world had complex and ambivalent attribute. Define digital design process as "Digital continuum" with characteristic of digital architecture and divided in 3-steps of concept - development - representation. Analyzed digital design process of Frank O, Ghery, Peter Eisenman and Greg Lynn on th assumption division. As a result, design concept is starting from three-dimensional thinking instead of existent two-dimensional thinking. And because general work of process was gone by digital media, "mass costomization" was possible. Also, it gave architect new role. Differ with former days, select various variables, should tuning and cording, and emphasize role as coordinator who must select the result. Digital is summoning very radical and epoch-making change in architecture. At center of these change, digital design process asks architect complex thinking and creative concept.

Digital technology in modern society is entering the era of digital convergence and ubiquitous computing, and is playing an important role to overcome the limitation of time and space. Based on new media method's rapid application development, a wide range of forms as digital design is made possible. A large part of our living such as information sharing, collaboration, production, recreation, working and various social activities has been realized from the space that digital media offer. As we see a much broader range, the digital media's diverse expressions affect, in interactive ways, not only the relationship between humans and things, between each individual human, and between humans and the environment, but also even emotional purification and realm of educational, cultural, and social aspect. In this study, the aim is to discuss the user-centered design considered for integration into the interaction space design method and is to concentrate on research on. Focusing on digital media, user-friendly interface features of the space environment, construction and utilization of digital media have been applied to try to analyze the interaction effect of space that is created for the design and application of various applications and will seek ways. Thus, various case-studies have been explored where interface space is developed, creating virtual reality through cognitive basis and 3-D interface space. For example, emotional expressions are embedded for the space of commerce, education and exhibition, enabling intercommunication through haptic interface, with changing sound and visual effects which are caused by the movement of people in a certain space. With consideration of the relationship between physical environment and objects, interactive design should be achieved by providing a human oriented interface based on social, cultural and environmental aspects.

디지털 방송과 데이터 방송 기술이 지속적으로 발전함에 따라, 디지털 방송에 신기술이 도입되고 새롭게 시도되는 방송 서비스가 계속 등장할 것이다 이미 가정에 출시된 STB가 새롭게 도입되는 신기술과 서비스를 계속 수용할 수 있으려면, 이때마다 기존에 탑재된 STB 의 소프트웨어는 새로 업그레이드되어야 한다. 일반적으로 STB가 한번 가정 내에 보급되면 STB에 탑재된 기존의 소프트웨어는 업그레이드되기가 용이하지 않다. 본 논문은 방송망의 전송 채널을 통해 STB 의 소프트웨어를 다운로드 받아 이를 업그레이드 시키는 소프트웨어 업데이트 시스템을 제시하고 구현함으로써, 현재 용이하지 않는 STB의 소프트웨어 업그레이드 환경을 극복한다. 제안하는 소프트웨어 업데이트 시스템은 데이터 카루셀 스트림에서 업데이트 될 소프트웨어를 다운로드 받는 (1) 다운로더 (Downloader), 다운로드된 소프트웨어를 설치하는 (2) 업데이트 로더 (Update Loader), 그리고 예외상 황이 발생하면 STB 가 새로 부팅될 때, 로그 파일을 이용하여 소프트웨어를 이전 상태로 복구시키는 (3) 리커버러 (Recoverer)의 세 가지 모듈로 구성된다. 소프트웨어 업데이트 시스템에서 다운로더는 지상파 디지털 방송 규격인 ATSC에서 제시한 소프트웨어 다운로드 데이터 서비스 규약 (A/97) 에 맞게 구현하고 ATSC 환경에서 이를 실험 검증하였다.

The expansion of media art has not only developed the digital technology but also given lots of environmental evolution to improve various fields of design as the main topic of the 21st century. The purpose of this study is aimed at proposing the new design that integrates fashion accessaries with media art technology. This will be done by understanding the social environment in digital ages and studying technology of design based on a variety of literature about changes in our society, neo value, vision, culture and art with fundamental notion of media art. First stage for this study, put an idea into just fashion accessary design because it is not sufficient to incoporate fashion and media art technology. The presented OLED(Organic Light Emitting Diodes) in this study is a kind of display to be in a limelight in the next generation and can be applied to various field of design. media art simultaneously moved into the scope of artistic debates. As a result, we can found that the use of audiovisual introduced numerous new aspects to the conceptual and aesthetic engagement with questions of conception. Today, the presented forms of art and inter-action from the closed -circuit work to interactive media art installations to open process-exist as parallel possibilities.

본 연구는 인쇄매체가 영상매체로 재매개 되면서 콘텐츠가 변화되는 과정을 분석한다. 미디어를 통해 콘텐츠가 생산되고, 기존의 콘텐츠가 새로운 미디어에 흡수되면서 변화하는 과정을 관찰하여 재매개된 미디어의 특성을 파악한다. 재매개의 이중논리를 적용하여, 인쇄매체가 영상매체로 재매개되는 과정을 분석하고, 그 결과를 통해 매체의 변화와 변용을 이용한 재매개 방식이 디자인에 방법론에 적용될 수 있다는 가능성을 제시한다. 마블 코믹스는 마블 시네마틱 유니버스로 재매개 되었다. 아날로그 미디어가 새로운 미디어로 재매개되는 현상을 이해함으로써, 디자이너가 디자인을 할 때 재매개의 특성을 이용하여 결과물을 도출 할 수 있도록 디자인 방법론을 제시할 수 있다. 매체가 발달함에 따라 디자인의 범주도 넓어지고 있다. 본 연구를 통해 재매개를 이용한 디자인 방법론 제시되길 기대해 본다.

노년세대는 발달과제인 '자아통합감'을 이루기 위해 기억, 평가, 종합의 역동적인 과정인 '인생회고'가 필요하다. 자서전 쓰기는 사고양상으로서 내러티브를 기반으로 인생회고의 도구 역할을 해왔다. 본 연구는 뉴실버세대에게 디지털 자서전이 자아통합감을 이루는 도구로서 본래의 역할을 충분히 할 수 있도록 고려해야 할 점을 모색하고자 한다. 이를 위해, 인생회고로 자아통합감을 이뤄가는 과정에 관한 이론들을 먼저 살펴보고, 자서전 쓰기의 양상 및 내러티브의 3가지 개념과 자서전적 글쓰기의 구성자질을 고찰할 것이다. 다음으로, 디지털 내러티브를 기반으로 한 디지털 자서전의 특징을 살펴보고, 뉴실버세대의 디지털 자서전 연구를 위한 고려 사항을 제안한다.

We proposed "Table Mediator" which is a tabletop system for digital storytelling that uses web-retrieved information for the students' educational field trip. Students can perform their storytelling for their virtual pre-field trip to build up a sequential path as a story with web-retrieved documents, satellite images, geographical information, and group discussion. The proposed system was designed to lessen the limitation of individual interaction such as restricted viewpoint and biased inclination by group digital storytelling. Local interactions also have the limitation such as insufficient information and knowledge and the system supplied the rich live information such as subjective critiques or recently discovered history, or new updates for building a story that makes users arrange their own idea as a consistent story to lessen the limitation of the local interactions. The system can be used for various applications such as travel, education and other collaborative works with group interaction.
