현재 3DTV 방송은 한국, 미국, 유럽 등 선진국을 중심으로 다양한 방식의 3DTV 실험방송 및 상용 서비스가 활발히 진행되고 있다. 3DTV 방송 방식은 기술개발 진행 측면에서 ⅰ) 서비스 호환 방식 지원, ⅱ) 기존 디지털방송 화질 및 최대 1080i 고해상도 지원이라는 핵심 기술개발을 목표로 점차 진화되고 있으며 전 세계 표준단체는 이를 지원하기 위한 서비스 호환 3DTV 방송 서비스에 대한 표준화가 본격적으로 진행 중에 있다. 본고에서는 ATSC(Advanced Television Sys-tems Committee), DVB(Digital Video Broadcasting), SCTE(Society of Cable Tele-communications Engineers) 및 TTA(Telecommunications Technology Association) 등 다양한 디지털방송 매체 기반의 서비스 호환 3DTV 방송 방식에 대한 국내외 표준화 현황에 대해 살펴본다.
