전 세계적으로 방송환경이 아날로그에서 디지털로 전환되어감에 따라, 선진국을 중심으로 POST-HD 시대를 선점하기 위해 치열한 경쟁을 벌이며 차세대 방송을 준비하고 있다[1]. 또한 디스플레이가 대형화되고 있고 초고해상도의 고품질 영상에 대한 소비자 욕구가 높아지고 있기 때문에 선진국들은 실감방송을 차세대 방송으로 설정하고 TV를 중심으로 화면의 대형화와 고화질화를 추구하고 있다. 본 논문에서는 HDTV방송에 비해 4배이상 16배의 고해상도를 가지고 화면이 커지면서 수평 시야각이 커져서 극장에서와 같이 현장감과 사실감을 제공하는 초고선명방송(UHDTV)을 중심으로 국내외 기술개발 동향 및 시장전망을 소개하고, 필요 요소기술을 도출하며, 기술수준 및 기술개발 정책방향을 도출한다.
