Abstract

This paper introduces an development of high-definition(HD) 3DTV experimental broadcasting system and its experimental service that has been launched via three broadcasting network including terrestrial, cable and satellite in the late of 2010. This 3DTV experimental broadcasting service employs an innovative 3DTV broadcasting mechanism, called as dual stream method in which left and right images are encoded by using each video encoder and multiplexed using MPEG-2 system technology for guaranteeing backward-compatibility with legacy DTV. This paper specifically describes the developed experimental broadcasting system, concentrating on 3DTV re-multiplexer and 3DTV receiver. Finally, implementation and terrestrial 3DTV experimental broadcasting service results will be introduced from the point of objective and subjective evaluation.

본 논문에서는 실험방송용으로 개발된 고화질 3DTV 실험방송 시스템 및 이의 성능 분석 결과에 대해 소개한다. 2010년 말에 성공적으로 실시된 고화질 3DTV 실험방송은 지상파, 케이블, 위성 3개의 방송매체를 대상으로 하고 있으며, 역방향 호환성을 보장하면서 고화질의 입체감 제공을 위해 듀얼스트림 방식을 채택하고 있다. 듀얼스트림 방식은 MPEG-2 시스템의 다중화 기술을 응용한 것으로서, 특히 지상파 방송의 경우 좌영상 인코딩은 기존의 비디오 코덱을 그대로 사용하고 동시에 우영상 인코딩은 효율이 향상된 비디오 코덱 기법을 사용하고 있다. 본 논문에는 고화질 3DTV 실험방송을 실시하기 위해 개발된 송수신 시스템의 구현 방법을 3DTV 재다중화기 및 수신기 위주로 기술하며, 마지막으로 시스템의 구현결과 및 지상파 3DTV 실험방송 실시 결과에 대해 객관적 및 주관적인 평가를 통해 검증한다.
