In 2D-to-3D video conversion process, the virtual left and right view can be generated from 2D video and its corresponding depth map by depth image based rendering (DIBR). The depth map plays an important role in conversion system, so the copyright protection for depth map is necessary. However, the provided virtual views may be distributed illegally and the depth map does not directly expose to viewers. In previous works, the copyright information embedded into the depth map cannot be extracted from virtual views after the DIBR process. In this paper, a new copyright protection scheme for the depth map is proposed, in which the copyright information can be detected from the virtual views even without the depth map. The experimental results have shown that the proposed method has a good robustness against JPEG attacks, filtering and noise.

Recently, with the diversification of media services and the development of smart devices, users have more opportunities to use digital content, such as movies, dramas, and music; consequently, the size of the copyright market expands simultaneously. However, there are piracy sites that generate revenue by illegal use of copyrighted works. This has led to losses for copyright holders, and the scale of copyrighted works infringed due to the ever-increasing number of piracy sites has increased. To prevent this, government agencies respond to copyright infringement by monitoring piracy sites using online monitoring and countermeasure strategies for infringement. However, the detection and blocking process consumes a significant amount of time when compared to the rate of generating new piracy sites. Hence, online monitoring is less effective. Additionally, given that piracy sites are sophisticated and refined in the same way as legitimate sites, it is necessary to accurately distinguish and block a site that is involved in copyright infringement. Therefore, in this study, we analyze features of piracy sites and based on this analysis, we propose an intelligent detection technique for piracy sites that automatically classifies and detects whether a site is involved in infringement.

It also covers related provisions of Borne Convention for the Protection of Literary and Artistic Works. The past study on the copyright protection has mostly focused on how we protect the copyright of publications and works which are published for profit.

This study analyzes the copyright problems of document delivery services based on interlibrary loan which are operated by KERIS and KISTI according to the agreements with KORRA. As a result of the study, we found that there are limitations of the libraries and copyright works to implement the document delivery services. Also, the electronic document delivery is the only between librarians and there is no provisions in the agreements for individual users who are not affiliated to libraries. This study suggests introduction of the ground provision for the interlibrary loan in the Copyright Act of Korea and development of authoritative guideline for details of document delivery services. Also, the study suggests that end users to request documents could be print out it but the library have to install systems to avoid copyright infringement. Finally, the study proposes the copyright fee based model for the document delivery services for individual users.

Technology and culture are converging with various industries to create added value of contents. In addition, the country is creating a foundation environment for grafting new technologies onto the cultural content. However, copyright infringement by voice demand and supply is continuously occurring for cultural contents with copyright, and more and more recently, there have been increasing cases of creating and operating sites with servers overseas to bypass monitoring on infringement sites. To prevent this, various copyright protection studies are under way in many areas, but the current detection and prevention technologies are largely reactive and therefore have problems of effectiveness. Accordingly, this paper proposes a model of the lifecycle of copyright infringement site to lay the foundation for preemptive response to the distribution of illegal copies through analysis of the lifecycle of copyright infringement site.

Information technology(IT) is changing rapidly based on growth of internet and computer businesses. Therefore, computer programs and softwares are distributed to computer users promptly for their productivity increase and efficient work. So, in the distribution, the softwares will be copied or released through network or other methods which are not authorized by the program owners. In that case, copyright dispute is incurred and various issues are come out due to infringement of the software copyright. Thus, the purpose of this study is to research infringement cases of the software copyright and how to settle the dispute which is related with software programs. To achieve the purpose of this study, this research consisted of 5 chapters. At chapter 1 introduction, it mentioned necessity of this study, purpose and how to research this study, and at chapter 2 dispute factors indicated and summarized for technical resolution. At chapter 3, infringement cases of software copyright analyzed and studied upon intellectual property(IP) related laws. And methods of dispute settlement discussed and suggested to chapter 4 for copyright and intellectual property protection. Also, it emphasized importance of arbitration to resolve the issues timely and avoid time and economical consumption. Of course, arbitration law has to be matched with the trend of technology development for effective settlement. At chapter 5 conclusion, it summarized this research and suggested further research for empirical test of economic value of the software copyright upon the aspect of business, law, and engineering. In this study, the results are 1) IP related laws have to be enacted or revised to meet technical changes for the protection of software copyright on time. The enactment or the revision of law takes a long time, therefore, to deal the dispute effectively, 2) arbitration law has to be utilized efficiently in order to resolve issues and settle the dispute promptly. It is suggested the dispute settlement through arbitration to save time and economic matters for legislation, and to harmony with the technology trends. 3) Recognition of software copyright is to be improved by users and enterprises for development of software related industries and intellectual property protection. In conclusion, the protection of software copyright is important than any other things in the field of IT because of the development of industry and intellectual property related laws. The development is for areas of business, law and engineering, so research and practices are to be combined with the areas so that it could resolve the dispute settlement and IP protection effectively.

This study aims to identify the effects of instruction methods on the students' knowledge and attitudes to persue an effective instruction for information literacy. For this purpose, a copyright class as a quasi-experiment is provided to students in a high school in different ways including the teacher-centered lecture and the student-centered Jigsaw cooperative learning program. As a result, Group D (Jjgsaw method) showed the highest educational effectiveness among the four groups in terms of the knowledge of copyright. the group also showed higher instructional effectiveness compared to other groups in the practical attitude, which was one of the three types of attitude to copyright.

Under copyright law, the writer' work is clearly protected, and any later producer who wishes to mount a copyrighted play or musical must obtain a license from the author, which may involve sharing royalties from the subsequent production with the author. Generally, directors do not explicitly enjoy similar legal protection for their creative input into a finished production. This Article explores the unsettled issue of copyright protection for stage direction in America. Firstly, it presents a few lawsuits on behalf of stage direction issues. It examines whether stage directions are possible for copyright protection through some pieces of articles. It looks at the contract form made by SSDC which is national labor union representing stage directors and choreographers. After all, I insist we acknowledge the copyright law and the value of copyright protection for stage directors' creative input into a performing arts production. We should devise the contract forms for stage directors which are to be applicable for each situations of productions.
