본격적인 지상파DMB 서비스가 시작되면서 사업자별로 다양한 데이터 서비스를 준비하는 등 비즈니스 모델 개발에 주력하고 있다. 이에 따라 DMB에 적합한 제한수신 시스템의 필요성이 이슈화되면서 국내에서는 현재 표준화 작업이 활발히 진행되고 있다. 본 논문은 지상파DMB 방송환경에서의 적용을 목적으로 하는 지상파DMB 제한수신 서비스를 위한 앙상블 재다중화기와 수신 검증 플랫폼의 설계 및 구현 방법에 관해 제안한다. 또한 제안된 앙상블 재다중화기를 통하여 스크램블링된 앙상블 스트림을 송출하고, 수신검증 플랫폼을 통하여 적용된 스크램블 모드에 따라 디스크램블링 및 디코딩하여 이를 디스플레이함으로써 그 성능을 검증하였다.
