SMIL is a declarative markup language based on XML, which enables users to make effective multimedia presentations on the web by synchronizing media objects. In this paper, we design and implement a SMIL authoring tool which support Intuitive creation of web multimedia documents and diverse practical use of created information. Besides, creation, management and authoring module of SMIL document, it offers template interface depending on network bandwidth selection for general users to create multimedia presentation a convenient way. In addition, we implement SMIL document management facility for a large number of users, by connecting SMIL contents database sever.

In this paper, an efficient system for finding answers to a given path algebra expression in a directed acylic graph is discussed more particulary, in a multimedia presentration graph. Path algebra expressions are formulated using revised versions of operators next and until of temporal logic, and the connected operator. To evaluate queries with path algebra expressions, the node code system is proposed. In the node code system, the nodes of a presentation graph are assigned binary codes (node codes) that are used to represent nodes and paths in a presentation graph. Using node codes makes it easy to find parent-child predecessor-sucessor relationships between nodes. A pair of node codes for connected nodes uniquely identifies a path, and allows efficient set-at-a-time evaluations of path algebra expressions. In this paper, the node code representation of nodes and paths in multimedia presentation graphs are provided. The efficient algorithms for the evaluation of queries with path algebra expressions are also provided.

Through reviewing and comparing the current virtual shopping malls web sites integrated VR into E-commerce, this paper analyzed both the advantages and disadvantages of two kinds of methods for product presentation: 2D image based and 3D model based presentation method. Using the virtual shopping mall (EasyMall) as a showcase, we presented the architecture of the system and the development technologies, especially those in the mixed presentation method. The presentation and customization methods in the two related modules, including the PhoneShow for mobile phone and EasyShow for textile products, were discussed. It indicated that the integration of E-commerce with VR could provide consumers with virtual experience and intelligent service for business activities. Furthermore, the product presentation methods can be made available for use in different cases.

The presentation of query results is usually made with an external tool or a report generator but, because the methods of preparing and storing presentations have not been standardized, there are many difficulties for other applications to use query results. Thus, it is necessary for a multimedia data query language to define presentation in a standardized method. In this paper we designed extented SQL is based on SMIL 2.0, which support the proposed presentation model effectively. Furthermore this study proposed methods of using query results in various multimedia applications.

To facilitate presentations of various media and transfer their implicit meaning efficiently, needed are effective development techniques for representing and manipulation temporal and spatial informations between multimedia data. Especially, these emporal and spatial informationsl are so deeply related with each other that it is required to have the integrated mehod for their representation. This paper suggests the Presentation Synchronization Trdd(PST) which represents their temporal and spatial informationsl and the efficient presentation model as traversing this PST. In this model, without knowing the specific user's interface or any script languages, the user can write the presentation scenario only based on allen's tecporal specification. This model has a characteristic of allowing user's inputs that may dynamically modify the presentation sequence in presentation time. As through the renmining steps of consistency checking for their relations. PST generation, and PST traversing step, this model provides users with simple and effective presentation of multimedial data by having them be presented auton\matically.

최근 멀티미디어 자료(Multimedia Data)들을 이용한 멀티미디어 상연물(Multimedia Presentation)의 제작에 많은 관심이 쏟아지고 있다. 한편, 멀티미디어 상연물들의 효과적인 사용을 위해서는 멀티미디어 상연물과 데이터베이스 시스템(Database System)의 통합(Integration)이 필요하며 이에 그래프 타입(Graph Type)을 이용하여 표현되고 있는 멀티미디어 상연물의 검색을 위한 검색 언어(Query Language)의 필요성이 대두되고 있다. 검색언어는 멀티미디어 자료들의 물리적 특징과 내용(Content), 상연물을 표현하는 데이터 타입(Data Type)을 표현할 수 있어야 한다. 또한 검색 언어는 사용자(end-user)가 손쉽게 사용할 수 있어야 한다. 이에 앞서 언급된 멀티미디어 상연물 검색 언어가 갖추어야할 요소들을 가지고 있으며 또한 사용자가 편리(user-friendly)하게 사용하는 visual language의 formal basis가 되는 calculus에 바탕을 둔 검색 언어인 GCaluculus/S를 소개한다.

As evolution of multimedia technology brings changes to industries concerned with design, new education program is needed to cultivate designers with abilities which are adapted to changed circumstance. This paper is purposed to show guideline to set up a fundamental course for multimedia design in which students know what are new presentation modes and learn how to use them, Multimedia design call for abilities of organizing information, representing, and implementing interactivity. Among them, fundamental course considers representing information as central subject. And it also contains lessons which are relative to proceeding courses. It should have students to experience creative composition and various expressions, and study cognitive or aesthetic effects of them. All activities are based on the understanding about presentation factors and principles. Basic course's lessons are composed by two main subjects, which are essential expression and matters relative to organization and interactivity. Described in detail, lessons are divided into three phases. First phase is combining presentation factors for affective effects, second is delivering message of various knowledges and third is forming simple interaction.

In this paper, a multimedia mail including video, sound, graphic data has been proposed as the next generation mail of the text based mail. In order to develop the multimedia mail, the most outstanding problem is the fact that the multimedia data are too huge to send them to the receiving end directly. The fact of big data may cause many problems in both transferring and storing the data of the multimedia mail. Our main idea is to separate between a control program for the multimedia presentation and multimedia data. Since the size of a control program is as small as a plain text mail, it has no problem to send it attached to the internet mail to the receiver directly. Instead, the big multimedia data themselves may remain on the sender's computer or be sent to a designated server so that the data may be transferred to the receiver only when the receiver activates the play of the multimedia mail. In this scheme, our research focus is paced on the buffer management and the thread scheduling for the real time play of the multimedia mail on internet. Another problem is to provide an easy way of editing a multimedia presentation for an ordinary people having no programming knowledge. For the purposed, VIP(Visual Interface Player) has been used and the results or multimedia mail implemented on LAN has been described.

In this paper, we describe an implementation of indexing and presentation system conforming to TV-Anytime standards. This system has a metadata indexing scheme for multimedia contents, a video indexing algorithm for news and soccer videos, and an MPEG-2 TS player for nonlinear browsing. We also implement an authoring tool for the algorithms mentioned above.

This study was conducted to develop web-based distance learning program of basic nursing physical science which was composed of a multimedia contents such as documents, voices and pictures. This was to advance curriculum of basic nursing physical science based on a proper nursing characteristics related to other major nursing subjects and induce a new and creative method to gain a knowledge. Based on a general learning design model, distance learning program was developed centered on a structure and function of heart physical science in 1999. The stages of development were like this. Firstly, at the analytic stage, specific units and contents for developing multimedia contents were decided and presentation methods for each item were designed and then the evaluation items were developed. Secondly, at the design stage, the most effective design of multimedia construction was selected and interfaces, basic frames, and presentation elements were chosen. Thirdly, at the developmental stage, internet files were designed using Namo web editor 4.0 and this files were modified with Adobe Photoshop.
