궁극의 3D 디스플레이 기술이라고 할 수 있는 홀로그램 기술로 실물을 보는 것과 같은 3차원 영상이 가능해 지고 있다. 그러나 디지털 홀로그램 영상의 데이터양은 HD나 UHD 영상의 수십에서 수천 배에 달해 원본 화질의 열화를 최소화 하면서 데이터양을 줄이기 위한 압축 부호화 기술이 매우 중요하다. 본 논문에서는 위상 홀로그램 동영상에 대해 최신 영상 압축 표준인 HEVC(High Efficiency Video Coding)와 VVC(Versatile Video Coding)로 압축한 후 홀로그램 영역과 수치 복원 영역에서 압축 성능을 비교하며, 다양한 실험영상에 대한 HEVC 압축 결과에 대해 객관적 압축성능 분석 및 주관적 성능 분석을 진행한다.
