Abstract

VVC(Versatile Video Coding)는 H.264/AVC(Advanced Video Coding)와 H.265/HEVC(High Efficiency Video Coding)의 엔트로피 코딩 기술로 사용되었던 CABAC(Context-based Adaptive Binary Arithmetic Coding)을 기반으로하여 압축율과 처리율을 향상시킬 수 있는 다양한 기술들이 채택되어 현재 CD(Committee Draft)가 완성되었고 참조 모델인 VTM6.0이 정식으로 배포되었다. 본 논문에서는 VVC Draft 6에 채택된 엔트로피 코딩 관련 기술들과 H.265/HEVC의 엔트로피 코딩의 차이점을 설명하고 엔트로피 코딩의 압축 성능과 엔트로피 코딩의 복잡도를 분석한다.
