최근 스마트 디바이스를 통한 일인형 미디어 소비의 증가와 초 고화질 미디어 서비스를 위한 획득, 압축, 전송 및 재현 관련 기술이 발전함에 따라, VR(Virtual reality) 미디어는 사용자에게 높은 몰입감과 현장감을 제공할 수 있는 차세대 미디어 형태 중 하나로 거론되고 있다. 이러한 VR 미디어 시장에서의 요소기술 선점을 위해 MPEG(Moving Picture Experts Group), 3GPP(3rd Generation Partnership Project), DVB(Digital Video Droadcasting)와 같은 세계 유력 표준화 단체에서는 관련 기술 검토 및 유스케이스 수집 등을 포함한 표준화 준비를 활발히 진행하고 있다. 본고에서는 상기 표준화 단체들의 표준화 동향을 살펴보고, 이를 통해 관련 핵심 요소기술들의 연구 개발 현황을 확인하고자 한다.
