현재 3DTV 방송은 UHDTV(Ultra High Definition Television) 방송과 더불어 차세대 방송기술로써 인식되고 있으며, 한국, 미국, 유럽 등 선진국을 중심으로 다양한 방식의 3DTV 실험방송 및 상용서비스가 활발히 진행되고 있다. 표준화 측면에서는 프레임호환 3DTV에서 서비스호환 3DTV 서비스로 발전되고 있으며, 방송망 및 IP망을 결합한 하이브리드 3DTV 서비스에 대한 표준화가 진행 중에 있다. 이러한 전 세계 표준화 움직임을 토대로, 본고에서는 ITU-T, SCTE, DVB 및 TTA 등 케이블디지털 방송 매체 기반의 3DTV 방송서비스에 대한 국내외 표준화 현황에 대해 살펴본다.
