최근 방송의 디지털화에 따라 수많은 채널의 수용이 가능하게 되어, 현재와 같이 신문의 방송편성표를 보고 사용자가 원하는 프로그램의 시작 시간을 알아내는 것은 힘들어 졌다. 디지털방송에서는 신문 방송 편성표와 같은 기능을 하는 방송 프로그램에 대한 정보를 보여주는 EPG(Electronic Program Guide)를 제공하고 있다. 현재 서비스되고 있는 EPG를 보면, 프로그램의 시작 시간을 GUI로 사용자가 쉽게 알아 볼 수 있어 하고 있어 신문 편성표나 인터넷으로 제공되는 각 방송국의 편성표와 달리 TV 화면에서 프로그램 정보를 검색할 수 있어 편리해졌다. 그러나 이 EPG에서 제공되는 시간은 매우 부정확하기 때문에 시청자가 불편을 느낄 수 있다. 본 논문에서는 방송의 시작 시간을 정확히 알아내어 EPG를 정확히 갱신하는데 목적이 있다. 이를 위해 방송의 시작부분을 미리 저장한 후, 시작 부분을 Visual Rhythm을 이용해 shot들을 추출하여 데이터베이스를 구성하고, 이와 같은 방식으로 방송 스트림의 shot들도 추출하여 데이터베이스와의 Pattern Matching을 통해 보다 정확한 방송시간으로 EPG를 갱신하고자 한다.

본 논문은 human visual system(HVS)에 따른 주파수 민감도와 공간에서 다양한 특성들을 구현하기 위한 신호처리 방법을 개발하였다. 인간의 눈은 주파수 성분에 따라 민감도가 다르며 초점에서 멀수록 인지 가능한 해상도가 떨어진다. 주파수 민감도를 구현하기 위해서 본 논문은 영상 신호의 에너지 스펙트럼 모양이 contrast sensitivity function(CSF)의 모양이 되도록하여 영상 신호의 에너지를 증가시켰으며 신호 방향에 적응적인 multiband energy scaling 방법을 개발하였다. 기존의 시스템에서 능률만을 향상시키는 기존의 분석 모델과 비교하면 개발한 방법은 HVS에 좀 더 적절하고 선호되게 영상 신호를 처리 할 수 있다.

When we see a binary black and white image, it appears. to our visual sense, to become clearer because of a pseudo halftone. This is because when we don't notice of all the details of the image, instead we see from a more global standpoint. We presented a theory and experimental results for layered model which extended external world, retina and brain of the two dimensional visual model. This paper propose the objective evaluation to coincide with the subjective evaluation of the human in ordered to evaluate the relative merits of the various modulation method. We obtain experimentally the restored images and the measure of approximation of the density four division and ordered dither method. The measure of approximation present s the objective evaluation scale to coincide with the subjective evaluation of the two modulation images.

MPEG-4 is a digital bit stream format and associated protocols for representing multimedia content consisting of natural and synthetic audio, video and object data. This paper describes an application where multiple audio/visual data stream are combined in MPEG-4 and transported via MPTG-2 transport streams(TS). Also, this paper describes how to convert MPEG-4 Over MPEG-2 TS bit streams into MP4 file which Is designed to contain the media information of an MPEG-4 presentation in a flexible, extensible format. MPEG-4 is presented in the form of audio-visual objects that are arranged into an audio-visual scene by means of a scene descriptor and is composed of the audio-visual objects by means of an object descriptor. These descriptor streams are not defined MPEG-2 TS. So. this paper focuses on handling of these descriptors and parsing TS streams to get MPEG-4 data. The MPEG-4 Over MPEG-2 TS to MP4 format converter is implemented in the demonstrated systems.

This study analyzes the Soju(Korean alcohol) advertisement image, which is relatively easy to interpret subjectively, among sexual appeal advertisements that stimulate consumers' curiosity, where the image is verified through AOI (area of interest) 3 areas (face, body, product), and eye-tracking, one of the psychophysiological indicators. The result of the analysis reveals that visual attention, the interest in the advertising model, was higher in the face than in the body shape. Contrary to the prediction that men would be more interested in body shape than women, both men and women showed higher interest in the face than a body. Besides, it was derived that recognition and recollection of the product were not significant. This study is significant in terms of examining the pattern of visual attention such as the gaze point and gaze time of male and female consumers on sexual appeal advertisements. In further, the study looks forward to bringing a positive influence to the soju advertisement image by presenting the expression method that the soju advertisement image should pursue as well as the appropriate marketing direction.

The term 'modern', in broader sense, refers to the concepts like modernity, modernization, modernism and the like, which came from Westernization impling the recognition of indigenous culture as being inferior to Western culture by comparison along with the expanded influences of the Empire of Japan. These concepts, however, rather than evolving from Western standards, came into being as a form of civilization led by Japan which had already tasted the fruits of modernization by 1920s. Since 1920s, the policy of, so-called, reconstructing Asian countries by Japan came to create eastern way of modernism, as a new East Asian trend mainly revealed in China which was against colonization after Japan's invasion and conquest of Manchuria. Therefore, Eastern' modern' unlike Western one could be understood in the widespread terminology, 'Modern(摩登)' in Shanghai, reflecting consciousness like 'Fashion' or 'Trend' in female images on a variety of visual media. By 1930s it was the most notable that 'modern' was accepted as something similar with 'Fashion', or 'Trend' in sociocultural contexts. These atmosphere had led commercial arts to enable to communicate with the public in a great deal of supports and success in Shanghai which was widely regarded as the citadel for the inflow of Western culture, among which transformations in female images were remarkable as a representative form of culture. It is also remarkable that 'historical modernity' transforming from the feudal age to modern society was considered a synchronic modernity, and nationalism was regarded as a sort of being modern, while involved in the newly-changed female images as a fashion mode. Changes in fashion including hair style in Shanghai by 1930s, as a way of expressions showing what was modern through commercial artistic productions, were easily noticed in visual media as an outlet of modern women's inner desire revealing their pursuit for new mode of life in metropolitan cities. As a characteristic of the time creating a new code of visual female images, it is notable that there existed another form of 'modern' satisfying socio-cultural needs of the general public seeking for being 'modern'.

Focus on Digital Fashion Image, the conceptual framework for the thesis is established from Virtuality in Digital Art. Formative characteristics and aesthetic characteristics were studied by classifying the Digital Fashion Image applied and expressed by digital media and technology. A detective research method was used for a case study. A literature study for case-by-case data was analyzed with focus on the works expressing fashion that utilized digital media and technology since the 2000s. Through this study, the Digital revolution has created the socio-cultural impact of a Virtual representation to implement technology and fashion culture that finds ways to take advantage of the image shown in a Digital Fashion Media by understanding Virtuality. The results are as follows. First, it was a re-formation of the fashion culture through the experience of virtuality with mental zone parameters between the media 'Mediation Code'. Reflect the reality of the virtual environment as represented by a cultural image of fashion brands and fashion that reset the team relationship and formed a Homo Ludens cultural code. Second, 'Interactive Exchange' acts on the exchange interaction between the method of digital technology, the human and the machine as well as the technical interoperability of network elements and techniques. This exchange is applied to fashion images that express emotion. Forming personalized fashion items and the user interactively storage that expresses the interactive exchange to forward the identity of the emotional fashion by a change in the message delivery system fashion. Third, the emphasis on intuitive artistic expression 'Synesthesia Immersion' induces a sense of immersion and excitement through the fusion of the interconnected. Enhance a visual image in fashion sensory representation and maximize a tactile and visual virtual reality involvement.

Theories and concepts emerging in new media environment are influencing the field of current spatial design. Art and technology have always coexisted, not but they are differentiated in two parts. They show new communicational paradigm in terms of supplementary position each other. The fact that examining the expression method and the communicational structure of today's new media art will be an analytical tool which analyzes the concepts of contemporary spatial design. For this, we attempt to use the Bolter and Gusin's remediation theory as analytical tool. First of all, we consider its theoretical aspects, and then, classify them according to the creation method, and investigate the characteristics of expression according to their types. We prepared an framework of analysis using the Remediation theory and its traits. We reviewed the relations between new media and spaces concerning remediation. After researching, we could analyze the cognitive aspects between new media and spaces as immediacy, and recognize the operational aspects of visual image as hypermediacy. Through the analysis, we could recognize the traits that digital environmental simulacres, sense of telepresence, and non-linear hypermediacy etc. remediate with repeating of mediation of mediation.

Most previous studies, in general, related to housing needs have analyzed the data from self-administered survey or interview using questionnaire or simple 2D floor plan. This study was Intended to suggest how to increase the reliability and effectiveness of such survey methods in examining the residents' housing needs. In order to accomplish the purpose, the two kinds of surveys using Web based VR media and typical questionnaire were peformed. The same questions were used for these two surveys, and they included the furniture characteristics, use of each room, adjustment of room size, preferences for interior colors, preferred furniture in living room, space layout of floor plan, housing life style, and preference for housing characteristics. The answer differences between these two were analyzed. The subjects were 402 housewives who lived in apartment houses in Haeundae, Busan. Finding were as follows: first, the media method was more likely to be effective than typical questionnaire survey in explaining housing needs for the adjustment of room size in housing unit plan. Second, the media method was more realistic and reliable than the other in comprehending the needs for the interior colors. Last, the VR media tended to be more effective than the other in understanding the space layout of floor plan. This research sheds light on the utilization of visual instrument for the analysis of needs related to space use.
