Digitalized multimedia contents is changing active digital contents in form passed from manufacturer directly to consumer though digital network of high speed, also face with big problem that is protection of rights to protect digital contents, to protect those and effort to active digital contents process height. Also, in situation that require change to more efficient system, the efficiency of rights document that is basic intermediate to be used in business of digital contents field is emphasized. Therefore, the design of common business model to share contents that have same purpose without depending on specific system to offer contents with another system is required. This paper designed adaptable rights business model to general digital contents, and designed and implemented rights document editing system to editable document for Right management according to designed business model.

The Internet provides a new way of doing business, but ease of copying and of sharing valuable digital information illegally across the Internet undermine many viable business models. This paper investigates the Digital Rights Management(DRM) as a means to provide safe protection and proper delivery of digital contents through the Information highway. First, we briefly summarize the current endeavor of DRM technical development and standardization process held in key technical working groups. Then, the paper provides a generic architecture for a DRM framework and shows the implementation of a prototype of DRM system incorporating key conceptual and technical standardization development. This study emphasizes the importance of developing the DRM architecture that provides the proper protection and safe transformation of digital contents in electronic commerce.

The purpose of this paper is to analyze the case of leading company in digital contents to promote industrial competitiveness of Korea. Analysis of this case study focuses on function and roles of leading company in digital contents industry. The main results of the paper are as follows: First, the government should prepare, main, and improve required technological and legal infrastructure for digital contents as quickly as possible. Second, the diffusion of the new digital contents companies can be promoted by ensuring fare competition and reliable market. For the inducing of this results, brainstorming methodology of related expert and survey research with leading company were applied to this paper.

Market penetration of media capital and with domestic broadcasting and communication fusion affect from the contents competitive situation which is general, the digital conversion of ground group broadcasting which follows in like this change tried to point out the hereafter direction of broadcasting contents industry with Korean-American FTA compromises. Further with role of the program heightening of competitiveness plan for the ground group digital contents activation of local broadcasting and loca broadcasting accomplishes the funeral of succession development and area public opinion integration of politics, economy and culture of the community and being understood for a harmony, and proposed a politic alternative in the Broadcast Communications Commission which starts newly and Local Broadcasting Developmental Commission.

Information producing and sharing methods are modified into digital forms. All kinds of documents are also converted into electronic forms so they become very useful and besides, they are increasing in quantity. Thus effective contents management system is requisite. Until now CMS(Contents Management System) has problems including composite contents management, processing delay and deterioration of contents because of deficiency of consistent contents storing methods and policies. In this paper an ECM(Efficient Contents Management) system is proposed for efficient processing of multimedia data and ubiquitous KM(Knowledge Management).

The purpose of this study is to develop online educational contents and verify its effectiveness in order to strengthen the learning capabilities of college students. The theme of mind map online education contents is a mind map series for effective learning arrangement, and has been developed into a total of six contents. Each contents consisted of 20-30 minutes, and the details consisted of the concept, principle, learning case, how to write a mind map, and how to use a digital mind map. The results of the study are as follows. First, it was confirmed that the higher thinking ability of college students who took the mind map online education contents was improved. Second, it was confirmed that the self-directed learning attitude of college students improved after taking the mind map online education contents. Third, the reason why students' higher thinking ability and self-directed learning attitudes improved in this study is that they were developed in consideration of the composition of contents and appropriate video time. Therefore, in order to increase the effectiveness of online educational contents, it is necessary to examine specific cases using concepts from conceptual approaches to specific topics, and to faithfully reflect the procedure in which each learner can actually use the concept.

This paper tries to solve the problems which previous methods have such as the WCDRM(Watermark and Cryptography DRM) and the model using smart card for protecting digital contents. This study provides a contents distribution model to protect the rights of author, distributor, and user as well as user's information by using technologies such as cryptography, DRM(Digital Right Management), access control, etc. The proposed system is evaluated as the most safety model compared with previous methods because it not only solves the problems which the previous methods have, but also protects four type of risks such as use of contents which other mobile devices download, the attack on the key to decode the message, the attack on leaking the contents, and the internal attack such as an illegal reproduction.

It is being emphasized that management of core process is another crutial factor in the development of a product, besides of management of quality factors for the product itself. The study purposes to introduce process quality concept to digital contents market, and also aimes at meauring of process maturity, based on level 2 and 3 of Capability Maturity Model, for domestic companies especially devoted to digital contents area. The result shows that the maturity level of most of companies surveyed is very low and that mobile and game fields are slightly more matured than animation field. The paper also proposes some of future efforts to be made fur improving maturity level of digital contents companies.

We use PKI technology for the digital content distribution in mobile environment. Encoding method is used TtipleDES and digital signature is used RSA. For the efficient methods and processes to the digital content distribution, we proposed the mechanism which consists of the sequential steps including the digital contents encoding step, rights management information signature step, and interconnection steps. As a result of this study, we propose the efficient and safe processes for the mobile content distribution environment.

The number of digital content used in mobile devices such as smartphones or tablet PCs has been rapidly increasing along with the development of IT industry. At the same time, studies on digital content management are actively conducted. One of the previous studies defined CTI(Content Tracking Information) for efficient management of the information on digital content usage between mobile devices in an area in which the internet is inaccessible, and suggested ways to deal with CTI management, reduction of the overhead and a technique of collecting as many CTIs as possible within a short time. This paper presents the design and implementation of a simulator capable of verifying the logic and the performance of the CTI management method. This tool simulates a mobile environment where devices move around in the internet inaccessible area and propagates digital contents each other. It shows several advantages including the efficient synchronization of CTI management and overhead reduction.
