Abstract
디지털 방송을 두고 IPTV와 디지털 CATV의 경쟁이 계속되는 가운데 방법과는 상관없이 방송된 콘텐츠 프로그램의 불법복제와 인터넷을 통한 배포의 피해 또한 커지고 있다. 디지털 CATV는 콘텐츠의 품질이 뛰어나 판매되는 DVD등의 고밀도 저장매체의 콘텐츠와 품질에서 차이가 없기 때문에 불법배포 시 문제가 크다. 하지만 사용자의 입장에서 방송프로그램의 녹화 및 재이용은 보장된 권한이고, 교육자료 등의 공정의 목적에서 녹화와 배포는 불법의 그것과는 구분이 필요하다.본 논문에서는 디지털 인증서를 이용해 녹화된 사용자 및 공정목적의 이용을 보장하고 불법배포를 제약하는 방송프로그램 유통시스템을 설계 및 구현하였다.
