최근 지상파 DMB 서비스를 위한 다중화 사업자들이 선정되어 이동 시에도 동영상을 포함하는 멀티미디어 방송 서비스를 위한 본방송을 준비하고 있다. 이러한 시점에서 다중화 사업자들은 송출되고 있는 방송의 상태를 확인하는 것이 필요하다. 더욱이, 지상파 DMB와 관련된 제품 및 서비스 개발자들은 필드 단위까지 방송 스트림을 상세하게 검토하려고 한다. 그러나, 현재 지상파 DMB 방송 스트림의 검증을 위한 방법이 제시되고 있지 않으며, 이를 위한 제품도 개발되어 있지 않다. 본 논문에서는 지상파 DMB 서비스를 위한 방송 상태를 검증하고 방송 스트림의 상세 정보를 분석하기 위한 방법을 제안하고, 이를 구현한 ETI 프레임 검증 시스템을 개발하여 상용 지상파 DMB 전송 시스템에 적용하여 실험하였다.
