Home Entertainment system is recently being offered by Home Theater & Smart TV with contents service. Also, console game is being played in the media like in TV. The usage of 4D as the main technology in entertainment industry has mostly been limited in Theme Park, Amuse Park, Theater, and contents for Movie and Animation. Some simulation systems for game has been developed but they were made mostly by using electric or hydraulic motion system which cause high power consumption and have a restriction of place for install. The paper is attempted to build Home Entertainment system which makes users feel realistic contents by developing 4D systems for Home Entertainment rather than before. 4D control S/W in which user can insert and edit 4D effects on contents of all areas such as game, movie, and broadcasting is developed. Also, built-in pneumatic cylinder in 4D system which can be easily controlled and managed in home is developed.

일반적으로 현재 사용하고 있는 홈시어터를 구성하기 위해서는 5.1 채널 이상의 아날로그 앰프를 주로 사용한다. 그러나 고성능의 시스템을 구성하기 위해서는 스피커의 출력이나 효율을 고려하여 음향 신호 처리를 디지털로 하는 것이 유리하다. 특히 음향을 효과적으로 분리하기 위해서는 7.1채널의 사용이 필요하다. 본 논문에서는 홈시어터 스피커를 위한 S/PDIF 7.1 채널 디지털 앰프의 구조를 연구하고 설계하였다. S/PDIF 7.1 채널 디지털 앰프는 노이즈에 강하고 S/PDIF를 사용하여 디지털 데이터를 직접 입력받아서 처리하기 때문에 디지털 원음의 손실이 적은 우수한 성능을 보여주고 있다.

The purpose of this study was to examine the impacts of educational theater on 5-years-old children, and more specifically, to find out whether the effects of the theater on children's peer acceptance and self-esteem are different by peer social statuses, that are, popular, average, and neglected/rejected Fifty seven children participated in this study and were evaluated with the Sociometric Test (Coie & Dodge, 1983). The experimental subgroup (N=28) participated in the programmed educational theater for 9 sessions. The dependent variables were measured by the peer acceptance items of Sociometric Test as well as the Self-Perception Profile based on SPPC (Halter, 1985), and the same tests were administered twice, before and after the experiment. Covariance analyses showed significant differences between experimental and control groups, for the children in the neglected/rejected category, in peer acceptance and social acceptance dimension of self-esteem. Global self-worth among children of popular and average categories, and total self-esteem among children of average category were also improved by the theater program. These results imply that educational theater programs can be used effectively to promote young children's social adjustment.

This study aimed to analyze residential demands on intelligent systems for apartments and suggest space design directions of intelligent apartment complexes. Data collection was done through mail-in surveys by five respondent groups. Outcomes of this study would provide basic data for developing intelligent apartment housing corresponding to the residential characteristics and demands of the five respondent groups. The sample size for the questionnaire survey was 592. The types of the target residents in this study were classified into five categories; nuclear families, dual income families, single households and the handicapped needing special environmental supports, and workers at home who need the new home design with a home office. The primary findings of this study were as follows. 1) For the controllers of intelligent system, nuclear families preferred TV, single households prefer home-pad which is movable and provides access to the internet. Dual income families, the handicapped and workers at home preferred remote control panels. 2) For the desirable space for computer equipment, regardless of the types of target residents, bedroom and living room were preferred. 3) For the desirable space for a home theater system, most of respondent groups preferred living rooms, but many rather wanted to have media rooms only for this system.

Wireless home theater and speaker system was designed. That has 20W output per channel, 0.1% THD (Total Harmonic Distortion) and automatic algorithm avoiding noise. The 3D stereophonic sound was realized through the wireless 5.1channel speaker system designed. That could be secured 0.4% improvement effect of THD compared with wire speaker systems. Specially in transfer sound with wireless, Frequency Hopping Spread Spectrum was superior than Direct Sequence Spread Spectrum in household electric appliances and wireless internet environment that radiated noise similar with ISM Band using 2.4GHz.

멀티미디어 부호화 기술의 발전에 따라 HDTV, DVD 등 고품질 멀티미디어 서비스가 가능하여 졌으며, 오디오의 경우 5.1채널 오디오의 사용범위가 점점 확대되어, 가정용 극장 시스템(Home Theater), 자동차용 극장 시스템(Car Theater)에 의해 일반 소비자들도 쉽게 접할 수 있는 서비스가 되었다. 지상파 DMB는 휴대용 방송 서비스로서 2005년 12월부터 본격적으로 서비스되고 있으나, 그 대역폭이 충분하지 않고 휴대용이라는 특성에 의해 멀티채널 오디오에 대한 고려를 하지 않고 있다. 최근 휴대용 방송 서비스를 위한 고효율 멀티채널 오디오 부호화 기술 표준화가 MPEG에서 추진되고 있음에 따라 DMB에서도 멀티채널 오디오 서비스에 대한 가능성이 열렸으며, 유럽에서는 이를 이용한 다양한 서비스를 시도하려고 계획하고 있다. 본 논문에서는 한국에서 서비스되고 있는 지상파 DMB를 통한 멀티채널 오디오 서비스의 가능성을 검증하기 위해 멀티채널 오디오 부호화 기술 및 검증 시스템의 구현에 대하여 기술하며, 향후 서비스 실현을 위한 가능성을 고찰하고자 한다.

A home network is a typical ubiquitous computing network that consists of various consumer devices and service environments. Home networks are requiring increasingly more complicated services, such as multimedia home theater and the monitoring and controlling of heterogeneous devices. Accordingly, a mutually connecting mechanism is needed among heterogeneous devices and services redundant. The current paper presents a Multimedia Room Bridge Adapter (MRBA) system that is designed to manage heterogeneous devices and support various services. In addition, a hardware and software prototype is implemented based on the proposed architecture.

The purpose of this study was to analyze the customer demand for design development of digital convergence furniture in the living space of the ubiquitous home. This study used the individual survey method and was collected from July 1 to 20, 2008. The frequency and percentage were used for data analysis by SPSS window's 12. The results of the study were as follows: The first, a lot of survey targets were 30-40 years old, university graduates, over 50,000,000 won in annual income and 30-40 pyung in house size. The second, what types of activity were carried out in the living room were acquisition of knowledge>entertainment activity>communication activity>household chores. The third, what types of furniture were used in the living room were A/V furniture>table>sofa>computer table>bookself. The forth, customers preferred to picture telephone service in sociality, home-theater service in entertainment and home appliances remote control service in information service. The fifth, the digital functions which can integrate with the living roon furniture, in the item for A/V furniture, was front door control function which recognizes visitors with the screen. In the item for table was function to search internet and for sofa was self purification function. Finally, the digital convergence furniture is not only for one activity but also for various types of activities that can comprehensively function to materialize the concept of comfortable furniture in the living space.
