디지탈 영상 신호의 효율적인 저장과 분배를 위해 만들어진 MPEG-1 표준과 MPEG-2 표준은 현재 디지털 AV 서비스에 널리 사용되고 있으며, 향후의 멀티미디어 통신 서비스, 디지털 TV, 고선명 TV 방송 및 VOD와 같은 대화형 서비스 등에 널리 이용될 것으로 예상된다. 또한 정보 통신 분야에서 그 수요가 폭발적으로 늘고 있는 개인 휴대형 통신 분야에서 영상 통신 서비스를 도입하기 위하여 최근 MPEG-4 표준화 활동이 시작되었다. MPEG-4 표준화 작업에서는 영상 내용을 이용하여 아주 높은 압축율을 실현하기 위한 여러 가지 새로운 영상 압축 기법들이 연구되고 있다.

This study investigated Korean TV advertising's creative strategy and trend. To achieve the goal, we conducted content analysis for prime time TV advertising messages (KBS, MBC, SBS). We found that Korean TV advertising contents showed more direct messages than indirect messages, much relationship between ads messages and product, more brand in advertisements, little humor, relatively many celebrities in ads. and much importance on the reputation of the firm. The findings will be a significant source regarding promotion strategy for global company who plans to enter into Korean market.

Traditional broadcasting environment is merged with various interactive broadcasting services, and the users use these services through Set-Top-Boxes. But they have limited user interfaces, which are not suitable for TV environments by adopting internet formats. Therefore, this paper suggests a User Navigating Interface which helps the audiences to select and watch their favorite channels more effectively. Firstly, this paper analyzes EPG interface - the most basic service in interactive broadcasting. Secondly, it suggests a user interface and service structure suitable in the network-integrated TV environment.

A novel real-time color gamut mapping method is described. The color gamut mapping method that is used for enhancing the color reproduction quality between PC monitor and printer devices is adopted for digital TV display quality enhancement. The high definition digital TV display devices operate at the clock speed of around 70MHz ～ 150MHz and permit several nano seconds for real-time gamut mapping. Thus, the concept of three-dimensional reduced resolution look-up table is introduced for real-time processing. The required hardware can be greatly reduced by look-up table resolution adjustment. The proposed hardware architecture is successfully implemented in FPGA and ASIC and also successfully adopted in digital TV display quality enhancement purposes.

This research explores the effect of features of political candidate on the electors' emotion and support. Though lots of researches have been proceeded about nonverbal communication clues such as posture, gesture, makeup, the research on the effect of glasses which can express in the face of candidate on the electors can not be easily found. For this experimental research, 2 group of subjects composed of university students was exposed to different type of TV address video and respond to survey questions which were analysed by SPSS program. This research found that the glasses of candidate could affect good feeling and support of electors but not on intimacy and confidence of them.

This paper describes a structure of adaptive equalizer to improve reception performance of ATSC digital television (DTV) for 8-VSB receivers. There are many strong and dynamic echoes affecting reliable reception of DTV signal. Conventional DFE based least mean square (LMS) algorithm is readily implemented and has good Performance. There are still problems to be solved, however, in handling strong echoes and indoor reception. In this paper, structure of adaptive equalizer to mitigate these Problems in strong multipath interference conditions and indoor reception environment is first presented. Methods to reduce error propagation effects on DFE and initialization scheme of filter coefficients for fast convergence are then introduced. Computer simulation results prove that an adaptive equalizer with proposed design methods can combat with Brazil Ensemble and the Threshold of Visibility(TOV) is improved.

Television News has significant impact on the information analysis of viewers by delivering world news to anonymous individuals everyday. We need to pay more attention to resolution considering the fact that even slight facial expression and the dress of TV anchor can be noticed by viewers in the high definition age, called HD TV, by radical changes in broadcasting situation. As a result, the beauty of expression that lighting technology has is extremely important in the high definition age. In news broadcast, as a phenomenon according to this change in trend, people have been looking for change in order to break with traditional TV news production by adopting DLP(Digital Lighting Processing) or LED(Light Emitting Diode). This effort has contributed to creating proper picture quality appropriate for HD TV. Nowadays Digital imaging is creating new trend in TV news production method from traditional analog-based lighting environment thanks to the development of IT(Information Technology) and digitalized lighting equipment. This change has led to building of HD studio and appropriate sets and lighting system. There are film set and projector which projects image on the screen and PDP, LCD, and DLP which has been used widely in recent years and LED which is often used as background in news program as examples, which has appeared since 1990s with HD TV. In this article, I analyzed the KBS News 9 lnce 1990s with in order to research the influence of television image component on the alyzed the KBS of TV article, I. I wille uggest the category of TV anchor image formulation in delivering information by means of lnce 1990s with based on the analysis result.
