본 논문에서는 ATSC3.0 기반 UHD 급 고정/이동방송 융합형 3DTV 서비스 시나리오에 대한 내용을 기술한다. ATSC3.0 은 북미지상파 표준화 방송방식의 차세대 지상파서비스 표준으로 2016 년 까지 기술표준 논의완료를 목표로 물리계층, 전송프로토콜계층 및 4K-UHD 서비스를 포함한 응용서비스계층으로 분류하여 표준화 논의 중에 있다. 본 논문에서는 스테레오 스코픽 콘텐츠의 좌/우영상을 각각 고정 TV 채널 및 모바일 TV 채널로 나누어 전송하고 이를 융합형 3DTV 방식을 지원하는 수신기에서 동시에 좌/우영상 신호를 수신하여 3D 영상을 합성하는 방법으로 지상파 DTV 한 채널(6MHz 대역)내에서의 4K-UHD 고정 TV 서비스, 모바일 HD 서비스 및 UHD 3D 서비스를 동시에 제공할 수 있는 고정/이동방송 융합형 3DTV 서비스 방법을 제시한다. 따라서 본 논문에서 제안하는 융합형 3DTV 서비스는 추가적인 3D 부가정보를 전송하지 않고 4K-UHD, 모바일 HD 및 UHD 3D 서비스를 시청자에게 제공 가능하다.
