  • The Terrestrial Digital Multimedia Broadcasting (T-DMB) system supplies high quality audio comparable with VCD in 7 inch display and high quality audio comparable CD at the mobile reception environment T-DMB will launch commercial service at the middle of 2005. However the bandwidth for audio data and the number of channels are restricted to 128 kbps and 2 respectively in the current T-DMB standard because of the limitation of available bandwidth for multimedia data. This Paper Proposes a novel media processor structure for providing multi-channel audio contents oyer T-DMB system allowing backward compatibility with the legacy T-DMB receiver. Furthermore. we also Propose an adaptive receiver structure to supply optimal audio contents on various speaker configuration in T-DMB receiver. To provide multi-channel audio contents allowing backward comaptilbity with the legacy T-DMB receiver, the additional data for multi-channel audio are defined as a dependent stream of main audio stream. The OD strucure for control an additional multi-channel audio elementary stream is proposed without changing the BIFS of the legacy T-DMB system.

  • Most of the existing interactive arts or entertainment systems consist of the following three steps: 1. the system's prompting the action of the participant, 2. action of the participant, and 3. response of the system. They do not presuppose these successive processes are performed continuously and repeatedly, and they are designed to express the concept of the work in each interaction. The opposite approach is to transmit the concept of the work in a continuous and repeated experience. The authors propose "Adjustive Media" as a type of work based on this approach. Adjustive Media has a spiral model with feedback. When participants experience the work repeatedly, they can recognize the difference of results between each interaction, and they can under- stand more closely the intent of the designer. This paper will propose 3 design processes for Adjustive Media as design method, and will introduce the prototypes of Adjustive Media.

  • This paper presents the interior space information using 6D-360 degree immersive media video information. And we implement the augmented reality, which includes a variety of information such as position information, movement information of the specific location in the interior space GPS signal does not reach the position information. Augmented reality containing the 6D-360 degree immersive media video information provides the position information and the three dimensional space image information to identify the exact location of a user in an interior space of a moving object as well as a fixed interior space. This paper constitutes a three dimensional image database based on the 6D-360 degree immersive media video information and provides augmented reality service. Therefore, to map the various information to 6D-360 degree immersive media video information, the user can check the plant in the same environment as the actual. It suggests the augmented reality service for the emergency escape and repair to the passengers and employees.

  • This paper described an Enhanced-xVSB system for improving mobile/pedestrian reception performance to the ATSC DTV 8-VSB transmission standard. E-xVSB system can transmit a mixture of normal (8-VSB) stream and enhanced (robust) stream. The robust stream has a higher threshold of visibility (TOV) compared to the standard stream, and legacy receivers ignore the robust packets. Thus, Enhanced-xVSB system is fully backward compatible with a current ATSC standard. for mobile and portable reception support, E-xVSB system adopts a reduced constellation method as well as enhanced trellis-coded modulation scheme. E-xVSB system supports a variety of enhanced modulation schemes: Pseudo-2VSB, Enhanced-4VSB, modified Enhanced-8VSB and Hybrid-VSB. Proposed E-xVSB system performs well under serious dynamic multipath reception environment.

  • PACS(Picture Archiving Communication System)를 바탕으로 하는 DICOM(Digital Imaging and Communications in Medicine)은 주요 의료영상장비들 사이에 데이터와 영상을 효율적으로 교환하고 전송할 수 있도록 마련한 표준안으로 현재 대부분의 최신형 의료영상장비(CT, MR, DSA, CR(Computed Radiology), 초음파검사, 핵의학검사, 내시경검사, 조직병리검사, 등)들은 의료 영상 분야의 국제 표준인 DICOM 표준방식에 의해 영상을 제공하고 있다. 최근 이러한 의료영상장비들은 독립적으로 사용하기보다는 의료수술 모니터링 장비 등의 비 의학영상장비와 서로 연계하여 사용하는 경우가 많아졌다. 그러나 이러한 의료수술 모니터링 장비들은 DICOM 표준 데이터를 고려하지 못하므로 PACS를 통한 데이터 연계에 어려움이 있다. 따라서 본 논문에서는 표준 DICOM 포맷과 의료수술 모니터링 장비의 데이터 구조를 분석하여 non-DICOM 의료수술 모니터링 장비의 PACS 연동을 위한 방안을 제안하였다.

  • Digital textile printing(DTP) is becoming more important because the production trend of textile printing goods is adapting to small-lot multiple items. Recently enhanced use of DTP is closely connected with production of high value-added products in fashion industry, which is also appropriate for quick response system(QRS). Quality of DTP depends on pre-treatment, after-treatment, ink, media, printer, etc. One of these parameters, Selection of good media is very important to obtain high quality of DTP products. Especially, the effects of media on printing quality of DTP according to yarn twist and structure of knitting fabric were examined in this study. Two types of yarn twist of 830 t.p.m and 1630 t.p.m for cotton knit were used and five types of media structures were knitted with single circular knitting machine. First, MIU, MMD, SMD's values are closely related with surface roughness of sample as well as printing quality. The hard twist samples were higher values than normal twist samples in the same media structure. In case of SMD, the values increased from plain to corduroy types. Second, aspect of line sharpness, line area, and line width values of hard twist samples decreased from plain to corduroy than those of normal twist samples. Third, line deviation values of hard twist samples, blurriness of line, also decreased than those of normal twist samples.

  • Today the influence of digital video media grows bigger due to the development of information and telecommunication gradually and most of juveniles spend a number of image contents with their smart phones and computers. And they not only consume such image contents but also upload the videos they make at YouTube or Vimeo by recording and editing them by themselves. As we learned from such phenomenon, the education of media that uses and expresses the video in various environment such as making, reading and expressing video media is very important. The education of using the advance digital device and software of producing image contents is essential as current education of media cannot be discussed without that. This study treats the education of media based on the view point of education on image contents production. It discusses the education method that we can learn from the process of image contents production based on Non-Linear Editing System.
