Nowadays, we make an attempt for media conversion from old to new media, carrying out to information society. These changes to new media are considered as new threat to printing media. New means such as CAD(Computer Aided Publishing), on-line novel and webzine can be regarded as new media and we are confronted with need of new changes in the field of printing media because of the trend of the present. It suggests that the origin of commodity competitiveness depends on the ability of cultural Contents using design. Cultural commodity is considered as strategy concepts in the more specific and realistic aspect than in the aspect of industrialization. This study introduce the case of Cellpark Co.,Ltd. which has successfully developed commodity design of World-cup cultural contents as a creating tools of innovative value connecting existed design method based on printing media with new method. This study gave the case which created Blue Ocean market through new expression method of design, products protection of contents design by patent registration, and licensing which many design firms often overlook.

Digital contents is used already in near place with us. Contents of MPEG-4 standard is used to process multimedia data in field of communication, computer, broadcasting mobile etc. However, absence of copyright management and protection system and interoperability problem of right system between each corporation happened. Because MPEG establish IPMP(Intellectual Property Management and Protection) system standard in agreement with MPEG-4 system standard, proposed cooperation method to manage and protect copyright. Accordingly, in this paper, put in copyright of authorized contents management and protection extension system implementation adding MPEG-4 IPMP system like plug-in into existing MPEG-4 authorizing tool. Therefore, author edits IPMP information to protect contents or object, and process the information in system and authorize MPEG-4 digital contents that have management and protection sign according to IPMP standard. This system designed and implemented to divided into IPMP information save processor, IPMP information creation processor, media IPPM processor, XMT-A to MP4 converter IPMP extension.

High-quality digital broadcasting contents are susceptible to illegal copy and unauthorized redistribution, which makes broadcasters difficult to protect valuable media assets. So, broadcasters and content providers need the technology for copyright protection of professional digital content. Digital watermarking technology is one of the most actively developed solutions for the copyright protection. This paper suggests the requirements of watermarking technology in DTV(Digital TV) environment for copyright protection and shows the developed real-time watermark embedding/detecting system for HD(High Definition)/SD(Standard Definition) video and experimental results of the system against watermark attack tests. Our watermarking system meets the watermarking requirements of invisibility, robustness and security of DTV environment.

멀티미디어 콘텐츠를 저작, 생성, 전달을 통해 최종 소비에 이르기까지 콘텐츠를 보호하고 안전하게 다루기 위해 MPEG-21 IPMP(Intellectual Property Management and Protection)가 표준을 정의하고 있으며 현재 FCD(Final Committee Draft) 단계까지 표준화가 이루어졌다. 우리는 MPEG-21 IPMP에서 규정한 FCD규격에 따라 멀티미디어 콘텐츠와 그에 대한 저작권을 보호 관리하는 시스템을 개발하였다. 제안한 MPEG-21 기반 REL및 IPMP 보호 관리 시스템은 크게 보호 관리 메타데이터 생성부, 통합 제어 관리부, 디지털 아이템 암호화부, 네트워크 인터페이스부의 4부분으로 구성된다. 이 시스템은 먼저 라이센스 서버를 통해 MPEG-21 REL(Rights Expression Language) 규격에 맞는 라이센스 정보가 담긴 문서를 파싱하는 기능을 가지며 오디오 또는 비디오 워터마크가 적용된 멀티미디어콘텐츠에 대해 MPEG-21 IPMP 기반의 메타데이터를 생성하고 보호 관련 REL및 IPMP 메타데이터와 멀티미디어 콘텐츠를 Remuxing 하여 전송되며 멀티미디어 콘텐츠 및 하나의 패키징된 DID는 암호화하여 최종 소비자에게 전송한다.

Digital Contents are increasing the modification of the contents by individual user and the modified or copied contents are simply distributed though the ultrahigh speed internet and the negative pervasive effect on the contents market is increasing. The solutions for copyright protection from illegally distributing contents are developing by various standardization groups and contents manufacturers and its commercia use is partly practiced. The MPEG was developing the IPMP technique to apply existed MPEG standards as a way of digital contents protection. However, as these IPMP techniques did not provide a satisfactory function for contents protection, the DMP standard was suggested as an alternative plan. In this paper, the system is designed and materialized to apply the TooIPack concept of DMP which ensure the interoperability of DRM system. With this paper, it is expected that the practical use and the possibility of the DMP standard in the DRM market would be verified and DMP standard may presents as a reference model for more systematic standardization operations.

A digital content have been utilized extensively without being limited to one territory of communication, computer, broadcasting, Mobile etc. A digital contents industry have been raised to a key point industry of a knowledge information society. An information infra setup of a global unit was processing to the development of Internet therefor copyright protection a digital contents and system for the officer have been desired. Like this, according as digital contents do fetters to MPEG-4 is circulated, copyright problem was risen. So, people had a lot of interests to protect and manage copyright. Hereupon, MPEG of the IS0/IEC established IPMP(Intellectual Property Management and Protection) standard, and supplements and corrects continuously standard. Therefore, existing system does fetters to MPEG-4 need system that process IPMP information. Hereupon. in this paper, designed system module that is processed by IPMP extension standard that progress now, and embodied copyright protection and management system that user can insert and update IPMP information efficiently within whole or specification part of MPEG-4 digital contents.

It is issued that protecting and managing a copyright are very important to a digitization of multimedia content. All of these techniques are for developing solution about protection and management of the copyright and media service. These have been at the head of the growth of the whole media service, but cause problems such as a illegal copy and distribution. To solve these problems, researchers are performing many projects. We analyze the trend of a multimedia service IPMP(Intellectual Property Management and Protection), DMP(Digital Media Project), ENTHRONE(End-to-end Qos through Integrated Management of Content, Networks and Terminals), and DRM(Digital Rights Management).

스트리밍(Streaming)이란 인터넷을 통하여 영상, 음악 등 디지털 멀티미디어 데이터를 실시간으로 전송하여 재생할 수 있는 기술이다. 인터넷과 통신 기술의 발전으로 인해 기존 다운로드방식의 디지털 정보는 실시간 스트리밍 형태의 서비스로 변화하고 있다. 또한 디지털 정보의 제작과 유통상의 용이함으로 인해 디지털화된 동영상 제작이 증가하고있다. 그러나 디지털 콘텐츠는 복제, 변형, 유포 등이 용이하고 안전하지 않은 인터넷을 통해 유통되고 있어 보안과 저작권 문제가 중요한 쟁점으로 대두되고 있다. 본 논문에서는 고품질의 스트리밍 서비스를 가능케 하는 MPEG-4를 대상으로 하여 스트리밍 환경에서의 콘텐츠 보호 방법에 대하여 설명한다.

This study explored the characteristics of media contents in the past, present and future. Also, it investigated the problems in terms of production of contents and circulation in order to find an effective way of providing contents that can keep pace with ubiquitous environment as well as one source multi use in various platforms and channels. In conclusion, it is viewed easy to expect that content would be the most valuable assets in ubiquitous media environments and the importance of contents will be more growing. Rather than game and enjoyment-related contents, more informative and cultural programs will be more valuable so policy-makers as well as industry need to more cultivate this area. In addition, this study presented the method for copyright protection and suggested that governmental policy fostering independent production should also be followed.
