The concept of a hyper-presentation, as an extension of a hypermedia, is the presentation in which time-varying multimedia presentations are dynamically linked together and a hyperlink's context can be changed over time at any time during a continuous presentation. While this concept provides users with a flexible and powerful presentation for their descriptions of the multimedia datum, inconsistency problems in the synchronized presentations occur by hyper links can be introduced. This paper introduces a method of describing the hyper-presentation using petri-net and propose a methods of checking It's inconsistent hyper link loop in the hyper-presentation description.

The concept of a hyperpresentation, as an extension of a hypermedia, is the presentation in which time-varying multimedia presentations are dynamically linked together and a hyperlink's context can be changed over time at any time during a continuous presentation. While this concept provides users with a flexible and powerful tool for their descriptions of the multimedia presentation, inconsistency problems in the synchronized presentations connected by hyper links can be introduced. This paper introduces a method of describing the hyperpresentation using Petri Net and proposes a methods of detecting inconsistent hyper link loop in the hyperpresentation description.

Character agent based Multimodal Presentation Markup Language(MPML) has been developed to increase the efficiency of the presentation using a computer. However, authoring of a presentation by using MPML is not simple because MPML describes only the behavior of the character agent. It describes the presentation background by importing HTML documents. This paper proposes EMPML(Extended MPML) which describes not only the behavior of the character agent but also the presentation background. And an authoring tool for the EMPML has been designed and implemented. By integrating the editing of the presentation background and character agent behavior, the proposed authoring tool supports WYSIWIG(What You See Is What You Get) mode designing. By using the proposed authoring tool, users can make a multimodal presentation without knowing the details of EMPML.

The concept of a hyperpresmtation, as an extension of a hypermedia, is the presentation in which time-varying multimedia presentations are dynamically linked together and a hyperlink's context can be changed over time at any time during a continuous presentation. Problems caused by integrating the hyperpresentation into an existing multimedia system which handles a sequential presentation only are, how to describe the hyperprcsentation, how to set up a hyperlink on a continuous media, and how to check the consistency of the synchronized presentations. In this paper. a new synchronization description method for the hyperpresentation and a method for setting a hyper link on a continuous media during" presentation are proposed after havin!; SHrvey of existing methods, The proposed method deals with only the DC value in a stream ut a DCT based compressed data for checking a condition of te link. Finally, the method for checking the consistency of mixed presentations before actual play of the hnlerpresentation is described. Proposed methods are implemented on MuX(Multimedia IO Server) where a sample scenario is tested.

The data models which express all types of video information physically and logically. and the definition of spatiotemporal relationship of video data objects In This paper, we classifies meta-model for efficient management on spatiotemporal relationship between two objects in video image data, suggests meta-models based on Rambaugh's OMT technique, and expanded user model to apply the adaptive model, established from hyper-media or web agent to VOD. The proposed meta-model uses data's special physical feature: the effects of camera's and editing effects of shot, and 17 spatial relations on Allen's 13 temporal relations, topology and direction to include logical presentation of spatiotemporal relation for possible spatiotemporal reference and having unspecified applied mediocrity.

본 논문은 인터넷상에서 사용이 가능하며 확장성이 뛰어나 XML(eXtensible Markup Language)을 다른 문서로 변환 및 브라우징(Browsing), 프리젠테이션(Presentation)이 가능한 표준 언어인 XSL(eXtensible Stylesheet Language)을 응용한 XSL 문서 편집 시스템의 설계 및 구현에 관한 것이다. 이를 위해 XSL문서의 기본 구조 단위를 패턴(Pattern)으로 구분하여 서식 집합(Template Rule)들을 사용자 서술 방식이 아닌 사용자의 선택 방식의 자동 생성으로 구성하도록 하였다. XSL 엘리먼트 (Element)의 선택방식은 구성되어진 XML문서를 읽어 들여 문서의 엘리먼트 정보를 확장할 수 있게 하였다. 또한 XML문서와 XSL문서의 HTML(HyperText Markup Language)로의 변환을 쉽게 확인할 수 있는 사용자 인터페이스(User Interface)를 구성하며 원활하게 문서를 교환 할 수 있도록 설계 구현 하였다.

하이퍼 프리젠테이션의 개념은 하이퍼 미디어처럼 시간에 따라 변하는 멀티미디어 프리젠테이션들이 서로 동적으로 연결되어 있고, 하이퍼 링크의 내용이 연속적 프리젠테이션 동안 시간에 따라 변화될 수 있는 것이다. 하이퍼 프리젠테이션 메일을 위해 PUSH 및 PULL 방식의 스트림 엔진이 사용될 수 있다. 협대역 네트웍망 또는 인터넷 망에서 하이퍼 프리젠테이션 메일의 연출을 위해서는 PULL 방식의 데이터 전송 방법이 유일한 대안이다. 주요 논점은 최적의 버퍼를 관리하는 방법과 실시간 연출을 위해 하이퍼 프리젠테이션을 포함한 스트림 스케줄링 기법을 찾는 것이다. 이 논문에서 하이퍼 프리젠테이션을 포함한 멀티미디어 메일의 개념을 제안하며, 역시 저속의 인터넷상에서 실시간으로 연출되어지는 프리젠테이션 메일의 방법을 기술한다.

Many people think, in common that An expansion toward outer city is a development, and it can be a general trends in a new development in a growing city. But We can see many case which moving of a public building are considerate as a core element to promote the new development towards outer city, and that is a negative element of slum in central area and community making. There are many aspects to pursue sustainable urban structure of in a city, and public building is a very important element to manage deteriorate central area from social slum in a old town. In this presentation, three project, Local Authority office of Chonnam province, Kwangju Station, and Hyper Urbanity, and it shows sustainable concept of the public building as a core in a city development. The effect of the projects are expected sustainable development and community in terms of social, cultural and historical aspects.

This paper describes a message model based on XML (eXtensible Markup Language) to present real-time data from sensors and instruments at manufacturing processes for web service. HTML (Hyper Text Markup Language) is inadequate for describing real-time data from process control plants while it is suitable for displaying non-real-time multimedia data on web. For XML-based web service of process data, XML format for the data presentation was proposed after investigating data of various instruments at steel-making plants. Considering transmission delay inevitably caused from increased message length and processing delay from transformation of raw data into defined format, which was critical for operation of a real-time system, its performance was evaluated by simulation. In the simulation, we assumed two implementation models for conducting the transformation function. In one model, transformation was done at an SCC (Supervisory Control Computer) after receiving real-time data from instruments. In the other model, transformation had been carried out at instruments before the data were transmitted to the SCC. Various tests had been conducted under different conditions of offered loads and data lengths and their results were described.

In order to provide real-time data from sensors and instruments at manufacturing processes on web, we proposed a communication service model based on XML(eXtensible Markup Language). HTML(Hyper Text Markup Language) is inadequate for describing real-time data from manufacturing plants while it is suitable for display of non-real-time multimedia data on web. For applying XML-based web service of process data in Intranet environment, real-time performance of communication services was evaluated to provide the system design criteria. XML schema for the data presentation was proposed and its communication performance was evaluated by simulation in terms of transmission delay due to increased message length and processing delay for transformation of raw data into defined format. For transformation of raw data into XML format, we proposed two structures: one is the scheme where transformation is done at an SCC(Supervisory Control Computer) after receiving real-time data from instruments. the other is the scheme where transformation is carried out at instruments before the data are transmitted to the SCC. Performances of two structures were evaluated on a testbed under various conditions such as six packet sizes and offered loads of 20%, 50% and 80%, respectively. Test results show that proposed schemes are applicable to the systems in Ethernet 100BaseT network if total message traffic is less than 7 Mbps.
