Abstract

본 발명은 기존 시스템과의 호환성을 유지하면서 다양한 포맷의 미디어 콘텐츠에 대한 불법적 이용을 원천 차단함과 아울러 시스템 부하를 줄이고 콘텐츠 재사용 가능성을 극대화한 디지털 미디어 콘텐츠 보호 시스템 및 방법에 관한 것이다. 상기 디지털 미디어 콘텐츠 보호 시스템은, 콘텐츠의 포맷을 분석하여 해당 포맷의 페이로드에 위치한 실제 데이터 영역 중 적어도 일부를 암호화하고, 암호화 키값 및 콘텐츠 정보 중 적어도 하나를 포함하는 암호화 정보를 상기 콘텐츠에 삽입하여 암호화된 콘텐츠를 생성하는 패키저 및 상기 암호화된 콘텐츠를 수신한 외부의 장치로부터 라이센스 요청 및 상기 암호화 정보를 수신하고, 상기 암호화 정보를 확인하여 상기 암호화된 콘텐츠를 복호화하는데 사용되는 라이센스를 발생하며, 상기 발생된 라이센스를 상기 외부의 장치로 제공하는 DRM 서버를 구비하는 것을 특징으로 한다.
