Teachers, who are the subject of on-site training, cannot create education content easily reflecting their experience for themselves, and also cannot distribute the content to leaners. Even though the content is distributed, there are limited in available devices as well as representable content features. So, an applicable authoring tool is needed at the user level. In this paper, we propose an authoring tool by which users and teachers can make education content easier based on WYSIWYG interface, and can distribute that. The proposed authoring tool supports various media education content of XML format so that viewers on various smart devices can see the content regardless of operating systems. And not only we conduct survey of users to evaluate convenience and expression of proposed authoring tool, but also we check whether the content can be equally visualized on various smart devices.

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.

We develop a simulation method that affords very high variability of virtual pedagogical situations involving many independent plans, still achieves authoring (or implementation) scalability. While each individual plan would be coherently drawn up by an agent for its respective goal, those independently-made plans might be coincidentally intertwined in their execution. The inevitable non-determinism involved in this multi-event plan encompassing pre-planned and unforeseen events is resolved by (multi-phase) dynamic planning and articulated sequencing of events in contrast to static planning and monolithic authoring in conventional narrative systems. Connections between events are dictated by their associated rules and their actual connections are dynamically determined in execution time by current conditions of background-world. This unified connection scheme across pre-planned and unforeseen events allows a multi-plan, multi-agent situation to be coherently planned and executed in a global scale. To further the variability of a situation, the inter-event coupling is made in a fine level of action along with a limited episteme of each agent involved. We confirm analytically the viability of our approach with respect to the situation variability and authoring scalability, and demonstrate its practicality with an implementation of a composite situation.

Interactive DMB contents are provided by MPEG-4 scene description. The abundant interactions of the user bring on the high bit rate of MPEG-4 scene description. But DMB system has low bandwidth and limited bit rate. So we need new authoring method for MPEG-4 scene description. In this paper, we proposed a seamless authoring method for the DMB environment. It can generate BIFS information tinily and dynamically. The research result can be used by DMB system for a seamless MPEG-4 contents transmission.

This paper introduces a new automatic processing system: "Contents Factory" for the mass production of contents. Through the contents factory, we provide an authoring environment to improve the usability and the efficiency in producing contents. The contents factory integrates recycling techniques for contents resources, contents development engines, authoring tools, and interfaces into a total processing system. Since it is multi-platform based including mobile devices as well as PCs, one can easily produce complete PC and mobile contents from raw resources. We produced an example, "Sejong square" via the contents factory in order to demonstrate its effectiveness and usability.

The popularization of IEEE1394(firewire) configuration in Desktop PC have done much to popularize Non-Linear video editing. DVD has been taking the lead in an age as the movie storage medium which represents a recent decade the place because of decreasing in cost of DVD-RW. But, it is the actual condition which has been had any research data about the process which produces the high quality movie of DVD to most ordinary people. Taking into account to capture the image with Avid Xpress DV and Adobe Premiere Pro which are representative video editing softwares in Desktop PC in general, we would like to close by proposing that DVD Authoring Process is available to keep high quality image in Desktop PC by the using of comparison and analysis of the image quality and export data which are able to be happened to the procedure of digitalization of video Authoring using of Adobe Encore.

This paper introduces an interactive contents authoring system which can easily and conveniently produce interactive contents for the Terrestrial Digital Multimedia Broadcasting (T-DMB). For interactive broadcasting service, T-DMB adopted MPEG-4 BIFS technology. In order to the interactive service becomes flourishing on the market, various types of interactive contents should be well provided prior to the service. In MPEG-4 BIFS, broadcasting contents are described by the combination of a large number of nodes, routes and descriptors. In order to provide interactive data services through the T-DMB network, it is essential to have an interactive contents authoring system which allows contents authors to compose interactive contents easily and conveniently even if they lack any background on MPEG-4 BIFS technology. The introduced authoring system provides powerful graphical user Interface and produces interactive broadcasting contents in the forms of binary and textual format. Therefore, the BIFS contents authoring system presented in this paper would vastly contribute to the flourishing interactive service.

As there is a growing tendency to represent the 3D content instead of the 2D content, researches for the stereoscopic image and video are under way in a variety of fields such as acquisition compression, transmission, authoring and display. The authoring technique for stereoscopic contents has given emphasis to virtual stereoscopic contents. Thus the authoring technique for stereoscopic pictures is insufficient. When we compose a stereo scene with stereoscopic pictures, stereoscopic contents may not match the stereo scene because each stereoscopic picture may have different camera condition. To solve this problem, stereoscopic pictures have been modified manually. It is a laborious work and will be spent much time. Also it is difficult for a user who does not have an elementary knowledge of stereopsis. In this paper, we propose the synthesis method to compose a natural stereo scene with stereoscopic still pictures and moving pictures. Experimental results show that the proposed method in this paper allows a user to synthesize stereoscopic contents easily and compose a stereo scene conveniently.
