최근 ATSC는 방송망 기반의 서비스호환 3DTV 방송서비스 표준완료 이후 이종망 환경에서 하이브리드 3DTV 방송서비스에 대한 표준화를 진행 중에 있다. 본 논문에서는 기존의 디지털방송 화질열화 없이 Full HD 3D 화질을 보장하기 위한 방송망 및 IP 망 연동형 3D 비디오 방송시스템을 제안한다. 특히, ISO/IEC 23009-1 DASH를 활용한 3D 부가 영상 전송, 이종망 환경하에서 안정적인 3D 비디오 동기화 및 하이브리드 3DTV 수신기 개발을 위한 시스템 타켓 디코더 모델을 기술한다. 실험 결과, 제안된 기술은 하이브리드 3DTV 방송 표준화에 직접적으로 적용될 수 있으며, 하이브리드 3DTV 인코더 및 수신기 개발에 있어서 참조 모델로 활용될 수 있음을 확인하였다.
