점점 현실화 되는 가상의 환경 내에서 자유롭게 시점을 선택하여 볼 수 있고 전방위 공간 내 몰입형 경험을 제공하는 VR(Virtual Reality) 미디어는 자연스러운 사실감을 제공함과 동시에 공간과 시간의 제약을 극복할 수 있는 실감미디어로 인식되고 있다. 이렇듯 VR 미디어의 출현은 한정된 시점에서의 입체감 및 고화질의 서비스를 제공하는 방식을 벗어나 전방위 시점에서 몰입형 서비스를 제공할 수 있는 발판이 되었으며, 이를 방송 및 통신환경에서 제공하기 위한 기술 개발 및 표준화에 대한 노력이 진행되고 있다. VR미디어는 사용자의 움직임 자유도 지원범위에 따라 3DoF(Degrees of Freedom) 및 6DoF 360VR로 분류되어 단계별 표준화가 추진 중에 있으나, 본 고에서는 3DoF VR 미디어를 중심으로 이를 서비스하기 위한 각 표준화 단체의 동향을 살펴본다.
