멀티비전이라 함은 하나의 영상을 확대시키거나 축소할 수 있고 이것을 다수대의 영상표시기기 등 영상출력수단을 연결 디스플레이하는 시스템을 말한다. 이와 같은 멀티비전 시스템은 최근 각광받는 디지털 사이니지용 스크린을 이용한 광고, 전시 홍보에 널리 사용되며 N-스크린 서비스와 같이 다양한 스크린 단말에서의 연동 서비스로서 활용될 수 있다. 본고에서는 디지털 사이니지의 멀티비전 서비스나 감시 보안용 멀티비전으로 사용되는 서비스 시스템에 대해 유형별로 조사해보고 장 단점을 비교해 보고 이와 같은 멀티비전을 활용하는 국내외 서비스 동향에 대해 살펴본 뒤 보다 개선된 멀티비전 시스템의 나아갈 방향을 제시하고자 한다.

In this paper, we propose a multi-vision based hologram display to improve the limited viewing angle problem of a single fan hologram display. Existing single fan type displays have a narrow viewing angle. And when the length of the fan becomes longer, there is a problem of low resolution. Also, it is difficult to change data due to the use of the SD card. So, we want to implement a dedicated app to transmit data via Wi-Fi. In this paper, we designed and implemented a display consisting of 3 REG LED fans. As a result of video transmission using the app, it was confirmed that it can be used for commercial purposes such as advertisements and demonstrations. The results of this study are thought to be of great help in the popularization of multi-vision holograms.

8K급 이상의 초고해상도/초다시점/초대용량 콘텐츠의 성공적인 시장 보급을 위해서는 콘텐츠의 실시간 재생이 가능한 단일 재생 시스템이 필요한 상황이지만, 현존하는 기술로는 해당 요구 사항을 만족하기는 어려운 상황이다. 이에 본 논문에서는 현존하는 재생 기술 기반으로 8K급 이상의 초고해상도를 갖는 콘텐츠를 효과적으로 재생하기 위한 GPU 기반의 멀티비전 시스템과 디스플레이 화면 간 안정된 동기 재생을 지원하기 위한 임의 순서 렌더링 방법을 제안한다.

As security and surveillance have become the center of interest, remote controlled CCTV(Closed-Circuit Television) market has been formed while rapid development of digital image compression technology and Internet triggered the advent of web cameras. The characteristic of web camera is that it can provide users with higher quality image than CCTV at any place where Internet access is available. However, As for the system administrator, the existing web camera have disadvantage in that they allows users only. who are connected to the server of the web camera, to see the image from it. In this paper, in order to make up for this defect, designed multi-vision interface showing multi images on single screen and, for the purpose of the improvement in efficiency, the functions of saving images and of scheduling the time to save the images.

Smart electronics are now widely used in everyday life, but the size of the screen of such devices is still too small to fully enjoy multimedia content. Therefore, if the display is comprised of multiple views produced by multiple smart devices, then the screen output size can increase. However, a time delay between the devices can generate a discordance in the video and sound. This paper compares two synchronization techniques that can be used to minimize such a time delay, and proposes a synchronization technique in which, the timing of the screen for each device is calculated by synchronizing the playback time, using the timing information transferred from the control device, and periodically adjusting the playback timing forward or backward. When multimedia content is reproduced using multiple views from multiple smart devices, we can minimize the time delay, regardless of the network quality or the differences in the devices used for this technique.

Our research is different form traditional to have some large LED screen grouping together to constitute multi-vision technique. In this paper, we purpose a method of using k-path diffusion method to build connect between the devices and find an optimal data transmission path. In second half of this paper, through practical application, we using this technique transmitting data successfully and achieving a simple Multi-vision effect. This technique possess smart devices and Wifi P2P's features, these features improve system's dynamic and decentralized processing ability make our technique has high scalability.

A new INS/Vision integrated navigation system by using multi-vision sensors is addressed in this paper. When the total number of landmark measured by the vision sensor is smaller than the allowable number, there is possibility that the navigation filter can diverge. To prevent this problem, multi-vision concept is applied to expend the field of view so that reliable number of landmarks are always guaranteed. In this work, the orientation of camera installed are 0, 120, and -120degree with respect to the body frame to improve the observability. Finally, the proposed technique is verified by using numerical simulation.

After the import liberalization of agricultural products, The Imported agricultural products rapidly increased market share of domestic agricultural products. But Imported agricultural products include various agricultural chemicals and food additives. In order to improve competitiveness in domestic markets of farmhouses and to secure food safety, the farmers needs to introduce Systematic support and various system. In this paper, established system that use Monitoring technology, to inform production information and management information about agricultural products to consumer by real time. Therefore unused analog camera such as CCTV(Closed-Circuit Television) for real time Monitoring. This system Used web camera that offer picture quality that is good than CCTV at place that consists network without distinction in the place. An advantage of real time Monitoring system designed multi-vision interface showing multi images on single screen and, for the purpose of the improvement in efficiency, the functions of saving images and of scheduling the time to save the images.
