The MPEG-4 standard is aimed to define an object based audiovisual coding standard to address the emerging needs from interactive broadcasting. Since a broadcasting program is created on the basis of its objects, it is considered that MPEG-4 is most suitable for interactive broadcasting contents production and it can be retrieved in terms of its properties. But, there is no system that protects the copyright of digital contents and manages copyright and possibility that contents producer and author's copyright receives infringement at process that exchange contents mutually rose very. Therefore, we need to control and distribute contents according to user's permission rights. In this paper, we present the authoring system based on MPEG-4 IPMP for copyright and protection of MPEG-4 contents. The main features of the proposed approach is to provide an MPEG-4 compliant IPMP authoring system in a plug-in type along with standardized interfaces, which is to be able to incorporated into an existing MPEG-4 content authoring system. In this way, it is capable of authoring content to the MP4 file format while accommodating protection and management of content in a unified way. Furthermore, it also allows a user to edit and/or author IPMP information in a more efficient way by offering form based user interfaces.

Software development process evolves by component based development(CBD) process and introduction to configuration management system is risen recently. In this paper, we explained component configuration management system evolved out of CBD methodology and focused on the specification management in component configuration management. The component specification is being based on XML that is a normalization document. Also, component version management and dependency management are achieved by a component name. And component dependency information is just the integration information using a component specification name used in the composition when component specification is composed. Thus we confirmed possibility of version management and dependency management using the specification.

The number of internet users rapidly increases, it has development of various learning method and education-contents. Currently, it has increasing of management, maintenance and reusing of education-contents through CMS (Content Management System) and SCORM(Shareable Content Object Reference Model) standard but actually, it has not more service for customer, In this paper, we propose CMS(Content Management System) using the supporting self learning method for increasing teaming effective of customer.

One of the main reasons of information divide of multi-cultural family is caused by language barrier that is associated with low education level. In addition the social problem can be triggered by the information divide that may increase the gap of economic inequality. With respect to the overall capability of accessibility of digital devices and the level of data utilization, the parent of muiti-cultural family's level is inferior to that of the parents of an ordinary family. However the traditional learning contents management system for those parents is not appropriate to decease the gap of the information divide. To handle this problem, it is necessary to construct a customized learning contents management system that is used to support the education of the parents of multi-cultural family depending on the level of understanding the learning contents written in korean. In this paper we design the korean to korean translation based learning contents management system and show the result of its prototype.

Content management, distribution system and DRM technology have been developed respectively, many contents services are more focused on the system like stability of distribution system or contents security than user-orient. In this paper, we would suggest multimedia contents management based on DRM and distribution model for the users of massive multimedia. The suggested model will be a total solution of content management, DRM and Watermarking functions as well as it will offer convenience to the users with Indexing DBMS which is focused on users.

콘텐츠 관리 시스템(CMS:Contents Management System)은 '자료 수집, 등록, 검색, 배포' 의 기본 흐름을 가진다. 콘텐츠의 등록 및 검색/배포를 위하여 각 시스템은 콘텐츠에 대한 별도의 메타파일들을 가지고 있으나, 이러한 메타파일들은 데이터 요소의 중의성이나 모호함 때문에 일관되고 객관화 된 스키마를 가지지 못하여 체계적 분류 및 최신 업데이트를 위한 메타데이터 자체의 효율적 관리 기능을 가지고 있지 않았다. 본 논문에서는 기존 연구되고 있는 MDR을 자체 개발 중인 콘텐츠 메타파일 관리 시스템(CMMS:Contents Metafile Management System)에 적용하여 메타파일의 체계적이고 효율적인 관리를 통해 기준요소로서의 메타파일 역할을 극대화하고 향후 타 체계와의 연동 및 확장성의 향상을 도모한다.

Recently, with the development of information and communication technology, digital pay-TV technology is paid attention. So the Protection of the provided contents is becoming more important. However, in order to encourage an active based on digital TV, the contents and information sent and received respectively by the broadcaster and the subscriber must be protected. Therefore, in this paper, I analyze the requirements to protect the digital contents, the security and efficiency of the previous digital pay-TV system model. Then I proposed a key management model for digital pay-TV system.

Today, the data broadcasting service provides various multimedia contents to users. This paper suggests a resource management system which controls multimedia resources in order to reduce the receiving time of the contents during the realtime data broadcasting of multimedia traffic information. To verify the efficiency of the resource management system, this paper has introduced the realtime traffic information integrating and authoring systems through MOT (Multimedia Object Transfer) protocol-based BWS (Broadcast Web Site) service in which multimedia data are transmitted by T-DMB (Terrestrial Digital Multimedia Broadcasting) and implemented a resource management system which controls the creation of multimedia resources in connection with the said systems. As the receiving time of the contents created with resources from the resource management system has decreased by 1/13, they are suitable for realtime data broadcasting.

On global interconnectivity, the activation of real-time and worldwide contents will permeate and impact all aspects of day-to-day life well throughout this century. In managing contents and models, we too will see the impact of this rapidly changing environment. The real time availability of contents pertaining to a companys supply chain through means of the Internet and mobile networks(e.g., the IMT-2000) will necessitate a change in decision-making processes for effective management of contents and models. To increase the availability of many contents and models, a management system should have adaptive function in proving adequate content and model for companies. In the respect of management of contents and models, this paper discusses a production mechanism of meta-knowledge for effectively managing contents and models. Through two experimental analyses with the production mechanism, it is proven that the system enabling adaptive contents and models provision goes beyond existing ones in view of efficiency of management of contents and models in the wire and wireless networks.

XML(eXtensible Markup Language) based electronic catalog is very useful for searching target information because of its structural and contents based searching support capability. And XML document editing is easier than HTML because of XML document is divided by structure, contents and presentation. This paper is to present a prototype of XML based Electronic Catalog Management System(ECMS) whose system consists of data input, output and manipulation system for inserting, updating, editing and deletion. A proposed system could resolved the problems at virtual intermediary shopping mall invloved in the difficulty of interoperability when customer try to compare similar products at mixed shopping mall and reduced web service costs at independent shopping mall by using XML format. The proposed ECMS offers rapid response capability for product data change of electronic catalog and easy and friendly interoperability among similar products.
