2009년 말 개봉된 영화 아바타의 흥행 성공과 함께 새롭게 시작된 3차원 영상에 대한 열풍은 영화뿐 아니라 방송, 게임 등 영상산업 전반에 커다란 파급효과를 가져왔다. 이에 그치지 않고, 디스플레이의 대형화 추세에 따라 대화면 TV가 범용화되면서 초고해상도 고품질 영상에 대한 소비자의 욕구가 어느 때보다 높아졌고, 주요 선진국에서는 Post-HDTV 시대를 선점하기 위하여 치열한 경쟁 속에 차세대 방송 서비스를 준비하고 있다. HDTV 이후의 차세대 방송을 UHDTV라고 하며, 가정에서 70mm 영화보다 뛰어난 화질(HD 화면 4~16배 크기에 해당, 최대 비디오 해상도 7,680×4,320)과 다채널(~22.2ch) 음질로 극장급의 초고품질 서비스를 제공하여, 소비자의 실감방송에 대한 요구를 만족시킬 수 있는 방송 서비스 제공을 목표로 한다. 본 고에서는 UHDTV 방송을 위한 국내외 관련 기술동향 및 표준화 동향에 대해 살펴보고, 끝으로 UHDTV의 향후 전망에 대해 살펴보고자 한다.
