본 논문은 한정된 대역폭을 갖는 기존채널을 통한 지상파 3DTV 서비스 화질의 한계를 극복하기 위한 비실시간콘텐츠 연동형 지상파 3DTV 방송 규격을 제안한다. 본 규격을 통한 서비스에서는 유휴시간의 대역폭을 활용하여하나의 스테레오스코픽 시점 영상을 비실시간 콘텐츠로 전송한 후, 실시간 방송 신호를 통해 전송되는 나머지 시점의 영상과 동기화하여 재생함으로써 기존 3DTV 보다 향상된 스테레오스코픽 영상을 제공한다. 상기 서비스의실현을 위해서는 다른 시간에 이종 매체를 통해 전송된 데이터들을 동기화하기 위한 새로운 방안이 요구되며, 이에 본 논문에서는 동기신호를 생성하여 실시간 방송 신호와 함께 다중화하는 방식의 기술적 해결책을 제시하고,이를 기반으로 한 고화질 지상파 3DTV 방송 규격을 제안하고자 한다. 본 논문에서 제안한 기술 규격은 2DTV 방송과의 호환성을 유지하는 동시에 기존 시스템의 변경을 최소화하여 비실시간 콘텐츠와 방송 신호간의 정밀한 동기화를 통한 고화질 3DTV 서비스를 제공할 수 있다.
