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. It 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. The reply management and script processing of UCC are given in the subsystem.

최근 정보의 형태는 텍스트나 이미지 기반에서 벗어나 복합 멀티미디어, 즉 동영상 위주로 빠르게 이동하고 있다. 특히 사용자에 의해 제작되고 유통되는 동영상 UCC의 급격한 부상은 사용자의 정보 생산력과 정보 공유, 소비 형태를 능동적으로 변화시키고 있다. PC 뿐 아니라 IPTV에서도 주요 서비스 모델로 관심을 받는 동영상 UCC는 향후 지식 결부형 학습 콘텐츠로 옮아갈 것이라 예상되고 있으며 여기에는 수익 모델의 개발과 저작권 보호 이슈가 해결해야 할 선결 과제로 인식된다. 이에 본 논문은 방송 콘텐츠 제공 표준 기술인 TV-Anytime, 학습객체메타데이터인 LOM(Learning Object Metadata)을 기반으로 OSMU 동영상 UCC 학습 콘텐츠 서비스 모델을 위한 에디터를 설계하고 외부 콘텐츠 소스를 활용할 수 있는 콘텐츠 저작 시나리오에 기반한 메타데이터를 설계하였다. 이를 통해 사용자의 다양한 지식을 활용할 수 있는 UCC 학습 콘텐츠 서비스 모델 발굴과 콘텐츠의 확대 재생산에 있어서 적극적인 저작권 보호가 이루어질 것을 기대한다.

Generally, conventional video searching or classification methods are based on its meta-data. However, it is almost Impossible to represent the precise information of a video data by its meta-data. Therefore, a processing method of video data that is based on its meta-data has a limitation to be efficiently applied in application fields. In this paper, for efficient classification of video data, a classification method of video data that is based on its low-level data is proposed. The proposed method extracts the characteristics of video data from the given video data by clustering process, and makes the profile of the video data. Subsequently. the similarity between the profile and video data to be classified is computed by a comparing process of the profile and the video data. Based on the similarity. the video data is classified properly. Furthermore, in order to improve the performance of the comparing process, generating and comparing techniques of integrated profile are presented. A comparing technique based on a differentiated weight to improve a result of a comparing Process Is also Presented. Finally, the performance of the proposed method is verified through a series of experiments using various video data.

Recently, as the growth of the Internet has led to a rapid increase in the consumption of multimedia such as photographs and moving images, the importance of metadata has been emphasized. In the case of existing metadata, only limited information such as GPS value or focal length according to the format is stored. However, with the development of mobile devices and multimedia acquisition devices, various sensors can be used in the devices. Therefore, this paper describes a method that can store not only the existing metadata format information at the time of multimedia acquisition but also another existing format of metadata such as information of various sensors which is the gyroscope and acceleration sensor of the device. We propose an application program that provides moving location information. The proposed method is expected to provide various applications such as image matching and effective image classification.

Although there have been a lot of researches on a video abstraction algorithm, the video abstraction tool is necessary to correctly pick up some important shots in a video because the important shots might vary on the person's subjectivity. This paper proposes a video abstraction and search system for making a video abstraction automatically or manually. Proposed system has two main components, server and client. The server generates the Metadata and makes a video abstraction file. The description for video abstraction file is based on MPEG-7. Since proposed system has a function to manually correct the results of each step, the author could produce a good video abstraction easily and efficiently. The proposed system could be used to build a digital video library.

MPEG-7 provides a lot of advantages for retrieving and editing of multimedia data by providing the information of structure and semantics in multimedia data such as digital images and audio. In this paper, a metadata generator and editor system for MPEG-7 is introduced. It suggests the overall technique and framework of generating and editing multimedia data when such content is created. This system also includes not only the functions of generating, editing and saving meta-data of MPEG-7 but also the functions of meta-data editing of moving pictures based on MPEG 1, 2 and browsing of the overall editing process.

일반적으로 동영상 검색을 위해 주석 기반과 내용 기반 검색을 사용하는데, 주석 기반 검색은 사용자의 주관이 개입되어 일관성을 잃기 쉽고, 내용 기반 검색은 동영상 데이터가 담고 있는 의미가 추출되기 어렵다는 단점을 가지고 있다. 그래서, 본 논문에서는 이 두 검색 기법을 상호 보완하여 검색의 효율성과 정확성을 높이기 위해 통합 동영상 데이터 모델(IVDM)을 제안하고, 이것을 기반으로 뉴스 동영상 검색을 위한 데이터베이스 스키마와 질의 유형을 설계한다. 이 모델은 동영상 데이터를 계층적으로 구조화한 형태로 상위수준에서는 주제별로 부여된 메타 정보로 주석 기반 검색을 지원하고, 하위 수준에서는 동영상 데이터에서 색깔, 모양, 움직임, 질감 등의 특징 데이터를 추출하여 내용 기반 검색을 지원한다.

디지털 기술이 나날이 발전함에 따라 정지영상 압축 기술의 대표적이라 찰 수 있는 JPEG이 탄생하면서 디지털 임상은 급격한 발전을 거듭해 왔다. 이에 동영상 압축 기술 MPEG이 탄생하였고, MPEG은 1, 2, 4 를 비롯하여 7, 21로 발전을 거듭하고 있다. PVR은 방송을 디지털로 저장하는 기기로써 시청자가 원하는 시간에 원하는 방송을 시청할 수 있게 해 준다. PVR이 많은 컨텐츠를 저장할 수 있게 되자, 사용자는 컨텐츠에 대한 효과적인 검색 및 브라우징을 필요로 하고 있다. 본 논문에서는 컨텐츠를 기술하는 메타데이터를 이용한 의미기반 브라우징 방법을 제안한다. 제안하는 방법에서는 메타데이터에 있는 키워드와 인물정보, 장르, MPEG-7의 color descriptor를 이용한다.

This paper analyzes metadata workflow from creation to browsing, and discusses metadata authoring and browsing technology. Unlike usual multimedia authoring, broadcast metadata authoring means metadata editing synchronized with video. In order to make practical application of other systems, the result is in XML or MXF(Material eXchange Format) based on common metadata scheme. The MXF Browser developed with the consideration of broadcast metadata that is time-synchronized with AV content provides not only metadata authoring capability but also advanced content browsing services such as summary playback and highlight browsing based on metadata multi-track.
