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.

In this paper, we present interfaces for IPMP services on MPEG Multimedia Middleware (M3W). For supporting normative IPMP framework based on MPEG-2/4 IPMPX, M3W IPMP tool interfaces are defined and far supporting MPEG-21 IPMP, REL and other related protective functions, M3W trust management interfaces are. Through the proposed interfaces, IPMP can be easily implemented under various environments and experimental results show some implementation examples.

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.

MPEG-4 디지털 콘텐츠는 통신, 컴퓨터, 방송, 모바일 등의 다양한 분야에서 멀티이디어 데이터를 처리하기 위한 표준으로 자리 잡고 있다. 하지만 저작권 보호 및 관리 시스템의 부재로 기업간 저작권 시스템의 문제와 관심이 대두되어 ISO/IEC의 산하기관인 MPEG에서는 MPEG-4 시스템 표준에 부합되는 IPMP(Intellectual Property Management and Protection) 시스템 인터페이스를 표준으로 제정하여 저작권을 보호하고 관리하는 공동 방법을 제공하였다. 이에 본 논문에서는 기존 MPEG-4 저작도구에 기반하여 MPEG-4 IPMP 시스템을 플러그인처럼 추가할 수 있는 확장 시스템 구현을 목적으로 두고 있다. 설계 부분은 IPMP 정보 저장부, IPMP 정보 변환부, 멀티미디어 처리부, XMT-A to MP4 컨버터, IPMP 정보 처리부로 구성하였고. 저작자가 IPMP 정보를 효율적으로 입력, 수정하고 시스템에서 처리되도록 구현하여 표준에 따라 보호 및 관리 신호를 갖는 MPEG-4 디지털 콘텐츠를 저작하였다.

MPEG-4 has mediocrity Standing encoding personality to process multimedia data including audio and video etc in the Internet and computer. It can use extensively without being limited to one territory of communication, computer, broadcasting, Mobile etc. 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 ISO/IEC established IPMP(Intellectual Property Management and Protection) standard, and supplements and corrects continuously standard.

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.

The usage increase of digital contents required solution for protection technology and interoperability of system. MPEG(Moving Picture Experts Group) proposed MPEG-21 Multimedia Frameworks. MPEG-21 IPMP is standard that provides the means to enable digital item and rights information to be persistently managed and protected across networks and devices. In this paper, MPEG-21 IPMP based system to protect digital contents designed by four structures of license server, production server, consumption server, tool server. License server create rights information document using the XML-based REL about multimedia contents of users. Production server makes a digital item by packaging multimedia resource and metadata, which is combined by REL information and IPMP information of multimedia resource. Consumption server takes care of the functions of players that use digital item, and tool server was implement to transmit for missing tool that might occur in all procedures.

Through the activities of MPEG (Moving Picture Experts Group), a number of issues have been identified within the scope of IPMP (Intellectual Property Management and Protection). This paper aims to address parts of them in the aspects of overall structure of MPEG-21 IPMP and to result in increasing the understanding of MPEG standardization works. In particular, this paper will address the major issues such as hooks, interoperability, and authentication architecture. Based on the architectures, this paper will explain how the MPEG-21 IPMP works with its components.
