Video documents which have audio-visual and other semantics information have complex relationship among media. While user requests for topic retrieval or specific region retrieval increase, it is difficult to meet these requests with the existing design methodology, In order to support the systematic management and the various retrieval capabilities of video document, we must formulate structural and systematic model on metadata using semantics and structural informations which are abstracted automaticallv or manuallv. This paper suggests generic metadata model with which we analyze the characteristics of video document, supports various query types and serves as a generic framework for video applications, we propose the generic integrated management model(GIMM)for generic metadata,, design video documents management system(VDMS) and implement it using GIMM.

본 논문에서는 동영상 정보의 효율적인 관리를 위해 주석 기반 검색과 내용 기반 검색을 통합적으로 지원하는 통합 동영상 데이터 모델(Integrated Video Data Model, IVDM)를 제안한다. IVDM은 동영상 자료를 계층적으로 구조화하여 상위 수준에서는 의미 단위와 세그먼트 단위로 주석 기반 검색을 지원하고, 하위 수준에서는 이미지 인덱싱을 이용한 내용 기반 검색을 지원한다. 우리는 이 IVDM을 이용하여 MPEG-2로 압축된 동영상 정보를 관리하는 시스템(Integrated Video Information Management System, IVIMS)을 개발한다.

Recently, in the elevator of the buildings, such as apartment and office building, the visitor monitoring cameras for surveillance, advertising LCD to provide a variety of information, emergency call devices, and safe driving information sensors are installed. A variety of multimedia data from these devices to the central control office, management office, or to guard room are transmitted in real-time. Each sub-systems in the elevator are installed with a separate lines and operated independently and use different management principals, so integrated management for each sub-systems are very difficult. In this study, we develop a new IP-based multi-channel video surveillance system which is integrated surveillance camera, emergency call devices, communications devices, various sensors in the elevator, DVR, ODM, and can manage all devices by two-way communication and integrated interface. And we evaluated the performance of the developed system.

In this paper, we apply the next generation Internet TV solution, FLV has been designed and implemented. Currently being broadcast in the field to compress HD video in real time, as well as live Internet VOD services are available through the online system, the Internet LIVE broadcast and VOD service easy to operate and UCC services that support the solution. VOD video cameras and in real time using H264 CORECODEC to compress MPEC4, WMV, and real-time video streaming on the Internet, and phone system that supports the first, real-time recording of camera images featured nation's first real-time encoder system (Real time encoder system) is, Web and smart environment suitable for supporting the latest CORECODEC technology and software products. Second, the video can be played in MP4 player and customize your chat, and Custer (customizing) is a possible two-way Internet Broadcasting System. Third, CMS (Contents Management System) feature video content and course management content in real time via the Android phone and iPhone streaming service is available.

In these days, production and management of various digital contents increased because of growing internet users. Now the digital contents production system is producing video which is based on keywords and contents. This paper proposes the sensibility-based contents management system which can analyze and manage contents of video production system. Due to the sensibility-based multimedia contents management system, it is possible to analyze and manage sensibility contents what users want. As a result, by building a database, we can provide intelligent and meaningful services. In addition, contrary to low grade's contents-based production system, we can cope actively with users' demands.

In this paper, we propose a new video structuring method for reconstructuring a 'structured logical video' which adds logical video information to a conventional structured video. Logical video information is composed of background, object, and situation. The proposed structured video is reconstructed in logical unit like episodes as well as in physical unit like shots. It can support many video functions and may be reusable in many video applications-video browsing, video retrieval, video editing, etc. we also present the video database management system in order to manage the proposed structured video is modeled on object-oriented concept and hierarchical structure. Also, we design and implement a video browsing and retrieval system using the proposed structured video.

Since the proportion of elderly citizens is increasing every year, the social interest is increasing for the health and the safety of the elderly. The nursing home is continually being created to care for more elderly people. However, the quality of service is not enough due to the lack of elderly caregivers. Elderly care and management services are being studied to replace the shortage of caregivers. Existing research for the implementation of an automatic care system has a high initial system cost. Furthermore, it lacks the ability to store and manage large amounts of data. In this paper, we propose a system that manages a large amount of data continuously generated through CCTV and provides a streaming service with a high level of quality-of-service (QoS) to users with collected video. Through the proposed system, it is possible to record and manage the behavioral information of the elderly occurring in the nursing home together with the video. In addition, according to the user's request, it has built a service that streams the video and behavioral information according to the date and time in real-time.

Video services over Internet is getting important. Since the service quality of the video service provided by streaming over Internet may be degraded, the quality assessment and management are very important. Currently the objective method based on the measured values of parameters is being widely used for video services. The subjective assessment, however, is more ideal in that the quality that is experienced by human. This paper, therefore, proposes a subjective quality management scheme for video service in a mobile environment that overcomes the limitations of the subjective method. The proposed scheme is expected to contribute to implement a more efficient quality management system for video services in a mobile environment.

In this paper, we design and implement the UCC services prototype system for image and video. The proposed system consists of the two components such as the multimedia processing subsystem and the metadata management subsystem, and provides the API to UCC service developers. The multimedia processing subsystem supports the media management and editing of image and video, and the streaming services of video. The metadata management subsystem supports the metadata management and retrieval of image and video, and the reply management and script processing of UCC.

Many system devices for fluoroscopic and general X-ray studies in diagnostic radiographic system have been being changed from analog mode to digital mode. In addition, among diagnostic imaging and radiologic examinations, fluoroscopic studies that requires functional diagnosis is being widely used. The video recording method of fluoroscopic studies has been useful in functional image diagnosis and dynamic image observation, but the utility of its image quality is being reduced because of limitation in setting play segments of the video player, inconvenience of play, difficulties in preserving reproduced images, the change of image quality, etc. In order to complement these shortages, it is necessary to facilitate access to patient diagnosis information such as storing, editing and sharing functional diagnosis images in response to the trend of the digitalization of digital radiographic & fluoroscopic system(DRF). Thus this study designed and implemented a device of storing functional dynamic images real time using a computer rather than existing video recording, aiming at contribution to functional image diagnosis.
