An increasing in quantity of multimedia data brought a new problem that expected data should be retrieved fast and exactly. The adequate representation is a key element for the efficient retrieval. For this reason, MPEG-7 standard was established for description of multimedia data in 2001. In this paper, we designed a Audio/Image Retrieval System based on MPEG-7 that can retrieve multimedia data like audio, image efficiently. And we integrated high-level and low-level schemas to retrieve datas for users.

최근, 컴퓨터 환경의 발달로 각 분야에서 AV(Audio-Visual) 콘텐츠의 사용량이 기하급수적으로 증가되었다 또한 컴퓨터, 방송 및 네트워크의 융합으로 이 전 보다 다양한 종류의 어플리케이션에서 다양한 형태로 AV 콘텐츠가 사용되고 있다 이에 따라, 이런 다양한 형태의 AV콘텐츠를 표현하는 방법 및 검색하여 사용하는 방법에 대한 많은 연구들이 이루어지고 있다 이런 연구들의 한 형태로 본 논문에서는 AV 콘텐츠를 표현하는 방법으로 MPEG-4 콘텐츠를 XML에 기반 하여 표현한 XMT(eXtensible MPEG-4 Textual fomat)와 AV 콘텐츠를 검색하는 방법으로 MPEG-7 표준을 사용하여 객체기반 MPEG-4의 콘텐츠 검객 시스템을 제안하였다 다양한 포맷의 미디어 데이터 및 그래픽 객체들을 각각의 하나의 객체로 간주하여 AV콘텐츠를 구성하는 MPEG-4 시스템을 XML을 기반으로 표현한 XMT 포맷으로는 MPEG-4 콘텐츠를 구성하는 미디어 데이터를 바탕으로 검색하는데 한계가 있다. 따라서 미디어 데이터 검색을 위한 메타데이 터의 표준으로 사용되고 있는 MPEG-7 을 사용하여 객체 기반 MPEG-4 콘텐츠 검색이 효과적으로 이루어질 수 있도록 확장된 XMT 포맷을 제안하고, 이를 사용하는 시험 시스템을 구성하였다. 이렇게 함으로써 MPEG-4로 표현된 객체 기반 AV 콘텐츠 검색 시 MPEG-7메타데이터를 사용하여 보다 사용자가 원하는 콘텐츠를 효율적으로 검색하여 제공할 수 있을 것으로 사려된다

The Ontology is the concept of human beings in any sense to classify things as departure from the classification based on the meaning at the prensent situation and concepts as the object of the Ontology. also, the technology is shared the conceptualization in a formal ontology as a meaning to give a clear description to the conceptual engineering in the ontology. Specialized multimedia broadcasting of TV-Anytime standard and multimedia representation of the overall standard of the MPEG-7 based on the concept of broadcasting multimedia presentations that can be used to develop an ontology who is required. In this paper, in TV-Anytime and MPEG-7 multimedia standard for broadcasting multimedia contents based on standards developed for the ontology, an ontology language for expressing OWL (Web Ontology Language) and RDF (Resource Description Framework) and the broadcast contents using To represent metadata of the system who has been developed.

This paper describes how to compose multimedia ontology for integrating/searching different types of multimedia databases. For this, we build integrated ontology based on MPEG-7 Multimedia Description Schemes (MDS), which is a representative standard for specifying multimedia contents, and the concept of TV-Anytime and re-express it using Web Ontology Language (OWL). In addition, we explain interoperability of the developed integrated ontology with other types of ontology with different concepts. Lastly, this paper describes the method of semantic search and retrieval using the integrated multimedia ontology.

An increasing in quantity of multimedia data brought a new problem that expected data should be retrieved fast and exactly. The adequate representation is a key element for the efficient retrieval. For this reason, MPEG-7 standard was established for description of multimedia data in 2001. However, the content of the standard is massive and the approach method is not clear for real application system yet, because of properties of MPEG-7 standard that has to include a lot of potential cases. In this paper, we suggested implementation scheme of retrieval system with using of only visual descriptors and presented the performance results of developed system. From the result of developed system, MPEG-7 VIRS (Video/Image Retrieval System), we analyzed the retrieval results between using individual descriptor and using multiple descriptors, and showed a layout for real application system.

This paper suggests metadata as an effective search tool suitable for moving images on the web. Dublin Core, a leading metagata sceme of web resources, and MPEG-7, a coming international standard developed by MPEG, are used to construct a hybrid metadata scheme. RDF is selected as a framework for a matadata description and Moving Image Core was developed as a RDF schema. Finally, RDF/XML encoded metadata of moving images are retrieved throuth web-based database system using ASP technology.

Recently, the capability of efficient access to the desired video content is of growing importance because more digital video data are available at an increasing rate. A video summary abstracting the gist from the entirety enables the efficient browsing as well as the fast skimming of the video contents. In this paper, we discuss a novel dynamic summarization method based on the detection of highlights which represent semantically significant content and the description scheme (DS) proposed to MPEG-7 aiming to provide summary description. The summary DS proposed to MPEG-7 allows for efficient navigation and browsing to the contents of interest through the functionalities of multi-level highlights, hierarchical browsing and user-customized summarization. In this paper, we also show the validation and the usefulness of the methodology for dynamic summarization and the summary DS in real applications with soccer video sequences.

본 논문에서는 현재 ITU-T와 ISO에 의해서 공동으로 표준화 작업이 진행되고 있는 H.264 ｜ MPEG-4 Part 10표준의 주요 테스트 모델 사항들에 대해서 특징을 서술하고 그 기능을 설명하고자 한다. 대표적인 테스트 모델 사항으로서는 RD 최적화 및 변환을 이용한 부호 모드 결정 기법, 오류 내성을 가지는 부호 모드 결정 기법 등을 들 수 있다. 현재 대역폭 제어 및 고속 움직임 추정에 관한 사항들이 테스트 모델의 발전을 위한 주요 과제로 연구가 진행되고 있다.

It is expected that intelligent broadcasting service (IBS) will be able to provide broadcast programs based on user preference and program-associated information (metadata) in order to assist users to easily navigate the program contents being broadcast. So users can access program contents anytime/anywhere in the way they want. In this paper we propose a framework for IBS based on an intelligent software agent platform so called FIPA (Foundation for Intelligent Physical Agents). We use an FIPA implementation. so called FIPA-OS, as a platform for exchanging user preferences and program information as FIPA messages between a server and clients. The user preference is modeled as the User Preference description scheme in MPEG-7 MDS (Multimedia Description Scheme).
