For interchange of multimedia informations and presentation as intented by objects composer, there are need to interchange format of informations and control synchronization between medias. And It is therefore need to provide a method and apparatus for synchroniztion control of multimedia objects which can control the conditional, temporal. and spatial synchronization in a MHEG engine developed to execute the functions defined as the international standards. In this paper. We propose to improved method and apparatus for synchronization control of multimedia objects which can execute the synchronized presentation by combining media data needed for presentation of multimedia information, and which enable the interactive processing between the user and the MHEG engine by allowing the user input to be processed during presentation.

This paper presents a multimedia authoring system in which user can create multimedia documents more easily and dynamic presentations can be supported. Our system defines a new time relation based on causal relation, so it controls effectively presentations when durations of media are changed in run-time. It supports dynamic authoring to feedback the consistency that could be occurred when users authorize multimedia documents. In our system, a multimedia document is represented to internal structure using trees through parsing phases, and a presentation engine is provided for processing dynamic presentations and user interactions in run-time.

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.

This paper explains design and implementation of Multimedia E-mail system as a research on multimedia service. It is based on MIME(Multipurpose Internet Mail Extensions) which extends RFC822. MIME is a standard mail tran sfer protocol which can include multiple objects in a single message, represent non-textual material such as images and audio, exchange without loss of multimedia information through SMTP(Simple Mail Transfer Protocol). It is implementation of Multimedia Mail system which can store, delete, edit and tran sfer multimedia mail misgave in user friendly way on UNIX system. It aims tp develope framework for multimedia E-mail system.

스마트폰이 일상생활에 보급되면서 모바일로 제작된 콘텐츠들의 연구 개발이 확산되고 있다. 학습, 여가, 운동 등 여러 분야에서 스마트폰으로 개발된 어플리케이션은 사용자로 하여금 스트레스를 줄여주고 편리함을 제공하고 있다. 본 논문은 스마트폰 Camera와 Video View를 이용하여 사용자와 영상 속안의 배우들과 호흡할 수 있는 모바일 1인칭 연기 시뮬레이션 어플리케이션을 설계하고 이를 구현하였다. 스마트폰의 영상에서 배우의 1인칭 모습이 출력되고 사용자가 선택한 명장면을 함께 진행한다. 본 연구를 통해 배우와 사용자 사이의 친밀감을 극대화시키고 잊고 있었던 명장면을 재조명할 수 있는 효과를 만들어 일상생활에서 느끼는 스트레스를 조금이나마 줄여줄 수 있기를 기대한다.

The modem multimedia applications which are video Processor, video conference or video phone and so forth require real time processing. Because of a large amount of image data, those require high compression performance. In this paper, the proposed image processing encoder was designed by using wavelet transform encoding. The proposed filter block can process image data on tile high speed because of composing individual function blocks by parallel and compute both highpass and lowpass coefficient in the same clock cycle. When image data is decomposed into multiresolution, the proposed scheme needs external memory and controller to save intermediate results and it can operate within 33㎒.

최근 인터넷의 발달과 사용량의 증가로 데이터의 양이 급증함에 따라 대용량 데이터를 효율적으로 검색하는 top k 질의 처리가 중요시 되고 있다. Layer 기반 방법은 가장 잘 알려진 top k 질의처리 방법이며, 객체의 모든 속성의 값들을 이용하여 객체들을 layer들의 리스트로 구성하는 방법이다. 본 논문에서는 그 중에서 convex hull을 사용하여 layer list를 생성하는 기존 연구를 조사하고 문제점을 파악한다.
