Various contents are needed by many users as more developing the internet technologies. However, the conventional contents service structure can't support these requirements sufficiently. Therefor, the UCC that novel contents type is made based on the Web 2.0 concepts. It is needed the contents authoring tools that can use easily for creating multimedia UCC. In this paper, we analyze problems of exist ActiveX based contents authoring tool and local application based contents editor. we design and propose new authoring system that solve problems of exist system.

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.

XML은 웹에서 구조화된 문서를 기술하는 전세계적인 표준 메타 언어로 정교한 검색을 지원하며, 쉽게 다른 목적으로 사용될 수 있다. Java는 다양한 플랫폼을 갖는 원격 학습 환경에서 효율적이면서도 안전하고 다양한 기능을 수행하는 시스템을 구현할 수 있게한다. 따라서 다양한 멀티미디어 구성요소들을 포함하는 코스웨어를 원격에서 교사들이 쉽게 개발하고 관리할 수 있는 XML 기반의 원격 코스웨어 제작 및 관리 시스템(X/RCAMS : SML-based Remote Courseware Authoring and Management System)을 Java 언어로 구현하기위하여 설계를 하였다. 이 시스템은 한 학교나 학습지 지역 분국에서 자신의 특성을 살리면서도 학습 정보의 상호 교류가 가능하며, 사용자가 사용하기 쉽고 사용자의 능동적인 참여를 유발할 수 있다.

With the ever-increasing queries related to temporal (or time-related) information, such as the product launching time, in search engine, most web pages will be augmented with such information in the future. Meanwhile, the gradual emergence of the use of electronic textbooks (or e-Textbooks), which enrich the traditional paper-based textbooks with multimedia contents such as interactive quizzes and multimedia-based simulations, has led us to infer that e-Textbooks will be blended with temporal information to support learning. The use of temporal information helps teachers and students to understand the level of prior knowledge required to study a topic, as well as the sequence of learning activities and related sub-topics, that best attains the educational goals. This paper presents a simple yet efficient tool called TimeMap, which is based on mind mapping, to create an e-Textbook called TimeBook that takes account of time-related curriculum and the ability of students to learn via collaboration.

For the efficient co-authoring of multimedia documents in a distributed systems environment, the cooperative-work management systems that can not only allow the sharing of distributed resources but also facilitate the authors' interaction, are needed. In this paper, we present a cooperative-work management system with hybrid architecture, called CW-MAN, in which the information on shared objects and co-authoring management is stored in a dedicated computer system but the shared objects distributed all over the local computer systems. The main management functions provided by the CW-MAN are those for shared objects, session, and telepointing. The shared-object use them exclusively. The session managements allows authors to dynamically create, update, and destroy sessions. Lastly, the telepointing management allows local pointing events to be synchronously presented to remote systems.

This paper describes a multimedia synchronization model based on the MPEG-4(Moving Picture Expert Group) system. It defines and modifies new nodes for representing temporal relationships between media objects in the BIFS(Binary Format for Scene) of MPEG-4 system which Integrates, manages and transfers multimedia objects such as audio, video, image, etc. The relationships are represented by using a multimedia temporal model during the start, play and delay time interval. In addition, we illustrate a multimedia authoring system that includes the Interface used for defining the temporal relationships. Differently from several contentional tools generally appropriate for professional users who can edit the BIFS nodes of themselves, the system provides end-users with the function that can define the temporal relationships of multimedia objects directly in the interface.

The contents of remote lectures are written by authoring tools or animation tools. Written contents then integrate existing medias, and are stored in a file type, which is added to the lecturing activities of lecturers. These files are stored according to the kinds of each authoring tool. So, there is no interchangeability and the efficiency of each media is not so good. Due to these structural features, it is not possible to do streaming lectures in on-line environments. In this study, a technique was suggested, which guarantees the interchangeability of remote lecturing contents using SMIL which is a synchronizing multimedia language. The suggested technique is an extended type of SMIL, and includes tags to represent the lectures of tutors which are the specific feature of remote lectures. Additionally, a model, which does streaming SMIL remote lecture contents through on-line, and which transfers control techniques are suggested. The remote lecture contents established by the proposed method can be applied to all authoring tools for remote lectures just by installing conversion modules, and can be a kind of expression model of the synchronizing model for streaming service in on-line environment.

This study proposes a method to develop an authoring system(GeoMaTree) for diverse trees that constitute a virtual landscape. The GeoMaTree system enables the simple, intuitive production of an efficient structure, and supports real-time processing. The core of the proposed system is a procedural modeling based on a mathematical model and an application that supports digital content creation on diverse platforms. The procedural modeling allows users to control the complex pattern of branch propagation through an intuitive process. The application is a multi-resolution 3D model that supports appropriate optimization for a tree structure. The application and a compatible function, with commercial tools for supporting the creation of realistic synthetic images and virtual landscapes, are implemented, and the proposed system is applied to a variety of 3D image content.
