현재 IPTV(Internet Protocol Television) 서비스 구조는 IPTV 사업자가 콘텐츠에 대한 저작권을 구매하여 콘텐츠 소비자에게 독점적으로 서비스하는 구조를 갖는다. 이와 같은 구조의 IPTV 서비스는 기존 방송과의 차이점을 갖지 못하게 된다. 이를 탈피하기 위해서 일반 콘텐츠 저작자의 참여 구조를 보장하고, 소비자의 콘텐츠 선택권을 확대할 수 있는 개방형 IPTV 서비스를 제공할 필요가 있다. 하지만 기존 디지털 콘텐츠의 유통 및 소비과정에서 콘텐츠를 보호하기 위한 각 제공 업체의 솔루션이 독자적인 방식으로 개발되어 이들 간의 호환성 문제가 발생한다. 이를 해결하기 위해서는 개방형 IPTV 환경 전반에 걸쳐 사용될 수 있는 멀티미디어 배포 및 소비를 위한 프레임워크의 확보가 필요하다. 이에 본 논문에서는 폐쇄형 IPTV 서비스의 독점적인 콘텐츠 유통 구조를 탈피하고 IPTV의 양방향 서비스 특성을 극대화하기 위한 개방형 IPTV 서비스 기반의 콘텐츠 저작 및 소비 도구를 설계하였다.
