본 논문에서는 방송 오디오 신호에 데이터를 부가하여 전송할 수 있는 방법으로 연구가 수행되고 있는 Active Audioprint 방식을 소개하고, 이의 적용이 가능한 응용 서비스들을 제시한다. Active Audioprint 는 별도의 데이터 전송채널을 통하지 않고 오디오 신호 자체에 삽입하여 전송하는 기술이며, Active Audioprint 기술, 응용 가능한 서비스 및 기술적 고려사항들을 제시하였다. Active Audioprint 는 향후 통합시청률 조사 및 방송 콘텐츠의 저작권 관리 등 다양한 분야에 활용이 가능할 것이다.
