현재 대중화 되고 있는 디지털 방송 이후의 발전방향인 Post_HD(High-Definition)서비스로 3DTV(Three Dimensional Television)가 대두되고 있다. 이와 같은 3DTV 서비스는 스테레오스코픽 영상을 구성하는 방법에서 이를 기존의 방송망에서 서비스하기 위한 방법까지 다양한 방법들이 연구되어지고 있다. 본 논문에서는 3DTV 서비스를 제공하기 위한 다양한 비디오 영상의 구성 방법에 모두 적용 가능한 전송방법으로 MPEG-2 전송스트림의 PMT에 스테레오스코픽 기술자를 추가한 방안과 MPEG-C part 3의 확장을 통해 스테레오스코픽 비디오를 전송하는 방안의 분석하여 고화질 스테레오스코픽 비디오 방송서비스 방안을 제안한다. 제안된 기술은 기존의 3D 방송을 지원하지 않는 단말에서도 기준영상만을 출력하여 기존의 MPEG-2 전송스트림과 호환성을 유지하고 있다. 따라서 기존의 디지털 방송과 스테레오스코픽 영상 서비스 지원이 가능한 규격으로써 향후 통신과 방송 영역에서 스테레오스코픽 기반 3D 서비스 활성화에 기여할 것이다.
