Abstract

ATSC is currently working on standardization of hybrid 3DTV broadcasting service in heterogenous network environment after completion of service-compatible 3DTV broadcasting service standard based on broadcasting channel. This paper proposes a convergence 3D video broadcasting method on broadcasting and IP network while guaranteeing a Full-HD 3D quality without degrading the image quality of legacy DTV. Specifically, this paper describes transmission of the 3D additional video using the ISO/IEC 23009-1 DASH, robust synchronization method under heterogenous network environments and system target decoder model for hybrid 3DTV receiver. Based on experimental results, we confirm that proposed technologies can be used as a core technology in the hybrid 3DTV standardization and a reference model for a development of hybrid 3DTV encoder and receiver.

ATSC는 방송망 기반의 서비스호환 3DTV 방송서비스 표준완료 이후 최근 이종망 환경에서 하이브리드 3DTV 방송서비스에 대한 표준화를 진행 중에 있다. 본 논문에서는 기존의 디지털방송 화질열화 없이 Full HD 3D 화질을 보장하기 위한 방송망 및 IP망 연동형 3D 비디오 방송방식을 제안한다. 특히, 본 논문에서는 ISO/IEC 23009-1 DASH를 활용한 3D 부가영상 전송, 이종망 환경 하에서 안정적인 3D 비디오 동기화 및 하이브리드 3DTV 수신기 개발을 위한 시스템 타겟 디코더 모델을 기술한다. 실험결과, 제안된 기술은 하이브리드 3DTV 방송 표준화에 직접적으로 적용될 수 있으며 안정적인 하이브리드 3DTV 인코더 및 수신기 개발을 위한 참조 모델로 활용될 수 있음을 확인하였다.
