양방향 증강방송 기술은 방송과 통신의 하이브리드 서비스 기술과 증강현실 기술을 융합하여, TV 방송 프로그램 시청 시에 시청자가 선택한 증강 콘텐츠를 방송 프로그램에 자연스럽게 융화시켜 즐길 수 있도록 한다. 또한 시청자의 선택에 따라 다양한 증강 콘텐츠 사업자들이 제공하는 증강 콘텐츠를 이용하는 양방향 서비스를 가능하게 한다. 본고는 양방향 증강방송 기술의 개요에 대해 소개하고 관련 연구 동향을 살펴본 후, 양방향 증강방송의 주요 기술 분야에 대한 각국의 특허 동향을 분석한다. 주요 핵심 기술 분야에 대한 특허 동향을 살펴봄으로써 양방향 증강방송 기술 분야에서의 국제 경쟁력을 분석하고, 향후 효과적인 연구개발 추진방향을 모색하고자 한다.
