최근 디스플레이 기기의 해상도에 대한 관심이 높아지면서 고화질용 멀티미디어 인터페이스의 중요성이 부각되고 있다. 화질 저하를 막기 위해 과거의 아날로그 인터페이스에서 디지털 인터페이스로 변화되었고, 이후 포트의 크기 축소와 음성지원의 필요성이 대두됨에 따라 고화질 멀티미디어 인터페이스(High-Definition Multimedia Interface: HDMI) 기술이 개발되었다. 2002년에 HDMI 규격이 발표된 이후, PC, DVD 플레이어, TV 등 다양한 멀티미디어 기기에서 그 사용이 꾸준히 증가되고 있다. 또한, HDMI 케이블의 전송거리 제한을 극복하기 위한 노력의 일환으로 최근 수백 meter에서 수십 km까지 전송이 가능한 광 HDMI 기술이 개발되어 그 활용도가 높아지고 있다. 본고에서는 HDMI의 기술동향을 살펴보고 최근 개발된 광 HDMI 기술의 개발현황을 소개하고자 한다.
