디지털 방송은 고화질, 다채널 환경을 시청자에게 제공할 수 있다는 장점뿐 아니라, 방송프로그램에 대한 저장, 편집, 배포 측면에 있어서도 높은 편리성을 가져옴과 동시에 방송프로그램의 무단 복제 및 배포라는 문제를 야기시키고 있다. 지상파 DTV 방송프로그램 보호기술은 방송프로그램의 무단 재배포 및 재전송을 방지함으로써 저작권자의 권리를 보호할 뿐 아니라, 방송프로그램에 대한 시청자의 공정이용(fair-use)을 보장함으로써 시청자에게 고품질 HD 프로그램과 다양한 디지털방송 서비스를 제공하는 것을 목적으로 하는 기술이다. 본 기고에서는 지상파 DTV 방송프로그램 보호 기술과 관련하여, 지상파 DTV 방송프로그램 보호 기술의 개념과 기술 요소를 살펴본 후 각국의 기술 동향을 소개한다. 그리고 지상파 DTV 방송프로그램 보호기술과 관련한 주요 특허 동향에 대해서 살펴본다.
