본 논문에서는 RTP, RTCP, SMIL 등을 이용하여 멀티미디어 데이터 전송시스템을 설RP 및 구현하고 QoS를 네트웍 레벨과 어플리케이션 레벨에서 개선하였다. 클라이언트의 구조적 정보에 의한 요청에 대해 서버는 멀티미디어 데이터를 RTP를 통해 전송하고 RTCP를 통해 수신자 리포트를 받아 QoS 파라미터를 결정하여 QoS를 개선한다. 클라이언트 프리젠테이션에서는 SMIL을 이용하여 각 미디어의 시간적, 공간적 동기화를 이룬다.

In multimedia database system, it is very important issue how to query multimedia data and present the result of query. Also, in order to reuse the query result in other applications, multimedia database system must be considered to provide the query result which is more generalized form. This paper includes the design and implementation of MMSQL query processor. MMSQL query processor provides the presentation of query result which is SMIL document. Therefore, MMSQL query result in this paper can be use to variant multimedia applications.

본 논문에서는 디지털 멀티미디어 컨텐츠의 효과적인 제작을 위해 멀티미디어 컨텐츠가 다양한 형태의 타입으로 표현될 수 있도록 하는 MPEG-4 컨텐츠 타입 변환기의 설계 및 구현을 제시한다. MPEG-4 컨텐츠 타입 변환기는 멀티미디어 저작 도구인 멀티미디어 Authoring Tool을 위한 핵심 보조 기술이다. MPEG-4 컨텐츠 타입 변환기는 효과적 타입 변환을 위해 MPEG-4, TRIF 및 SMIL을 포함하는 중간포맷을 정의하여 이용한다. 즉, MPEG-4, TRIF 및 SMIL로 정의된 각각의 트리 형태의 데이터와 중간자적인 트리 형태의 중간 포맷 간에 양방향 변환을 가능하게 하여 손쉽게 다양한 타입으로의 변환을 가능하게 한다. 그리고, 각 트리 형태의 멀티미디어 데이터는 그에 해당되는 스트림의 형태로 트레이스 되어 출력되며, 실행 가능한 데이터를 생성하기 위해 Encode와 Mux 또는 파싱을 실행한다.

하이퍼 프리젠테이션은 다양한 멀티미디어 객체를 표현하는 기술로 교육, 광고, 엔터테인먼트, 잡지, 협동작업 등의 응용분야에서 적용될 수 있다. 이를 위한 하이퍼 프리젠테이션 엔진은 프리젠테이션 시나리오에 포함된 멀티미디어 객체들 간의 시간적관계 및 사용자와의 상호작용을 처리해야 한다. 이 논문은 프리젠테이션 시나리오 기술 언어인 SMIL(Synchronized Multimedia Integration Language)로 표현된 하이퍼 프리젠테이션 시나리오를 브라우징하는 비라우저 엔진에 적용하기 위한 트리거 모델을 제시한다. SMIL로 표현된 객체들 간의 시간관계를 고려하여 시간 동기화를 처리하기 위한 이벤트와 사용자 행위나 브라우저로부터의 이벤트 등을 정의하였고 이를 수행하기 위한 트리거 실행모델을 기술한다.

If a digital signage system is operated in PC mounted in the Window OS then the implementing price is very high. For resolving this problem, we used the Smartphone mounted in ARM Cortex family of multi-core processor-based mobile platform. We developed a low-power low-cost digital signage system and a remote convergence content management program based on web server. This convergence system manages advertising content to a remote control device anywhere using remote control technology. This system is one integrated system with display and is a low-power consumed and is developed in very efficient hardware interface. And condition sensors(intensity of illumination, temperature, weather, GPS etc) is equipped in the developed system. Automatic contents builder and Context-aware SMIL module is also implemented in the convergence system. We achieved over 50% power savings comparing with conventional Window OS system and 16 points multi-touch in our system.

The purpose of this research is to establish a method for the construction of a multimedia electronic dictionary system by integrating the media data available from linguistic resources on the Internet. As the result of this study, existing text-oriented electronic dictionary systems can be developed into multimedia lexical systems with greater efficiency and effectiveness. A method is proposed to integrate the media data of linguistic resources on the Internet by a web browser. In the proposed method, a web browser carries out all the work related to integration of media data, and it does not need a dedicated server system. The system constructed by our web browser environment integrates text, image, and voice sources, and also can produce moving pictures. Each media is associated with the meaning of data so that the data integration and movement may be specified in the associations. SMIL documents are generated by analyzing the meaning of each data unit and they are executed in a web browser. The proposed system can be operated without a dedicated server system. And also, the system saves storage space by sharing the each media data distributed on the Internet, and makes it easier to update data.

The Internet had been taken properties which were both a slow speed and low-bandwidth of the first time. It was impossible to transmit large multimedia data because of a Internet properties. After tens of Year Passed, many people began to transmit multimedia data in the Internet which had fast-speed and high-bandwidth. Some people want to team classes to be taught in school through the Internet. And, educators wish to use multimedia data in the educational field. Due to previous reasons, many parts in the educational field had tried to join real-time objects to multimedia objects. But, real-time data didn’t appear easily due to many faults like network errors and system bugs if we want to control data in order to teach and learn classes. Then, this paper separates real-time and unreal-time data and controls these data that aye made a time scheduler to have time information in the extended SMIL-file for deceasing these faults.

The XMT standard is MPEG-4 Scene Description of textual format. It can be utilized to edit the audio/video media for broadcasting and develop the user oriented media contents. This paper proposes XMT authoring system that supports exchange among contents in various presentation environment. The XMT authoring system creates two levels of textual syntax and semantics: XMT-$\alpha$ format and XMT-$\Omega$ format. Because XMT-$\alpha$ and XMT-$\Omega$ have different expression method about an object, the authoring tool offers interface for them. the authoring tool offers interface for them. Also, it defines interior data structure that can support two file formats, and offers the function that transforms XMT-$\alpha$ into BIFS and transforms XMT-$\Omega$ into SMIL or XMT-$\alpha$. It offers interoperability among multimedia data in various environment that is XMT's characteristic.
