본문에서는 TMIV 에서 비디오 코덱으로 사용되고 있는 HEVC 를 MV(Multiview)-HEVC 로 대체한 실험결과를 소개하고 부호화 효율을 향상시키기 위한 아틀라스 생성 구조에 대해 제안하고자 한다. 이를 위해 본 논문에서는 푸루닝(pruning)된 패치를 패킹한 아틀라스 영상으로 구성된 MIV 앵커(anchor)에 MV-HEVC 를 적용하는 구조, 소스 시점영상으로부터 선택된 기본 시점영상으로만 패킹한 아틀라스 영상으로 구성된 MIV view 앵커에 적용하는 구조를 실험한다. 이와 더불어 부호화 효율을 향상시키기 위해 선택된 기본시점 영상을 패킹함에 있어서 2 개의 아틀라스영상에 걸쳐 가장 인접한 시점을 배치하는 아틀라스 영상 구조를 제안한다. 실험결과, 기존의 MIV 앵커에 MV-HEVC 를 적용하면 성능 개선이 거의 없으며, MIV view 앵커와 제안한 MIV view 앵커의 아틀라스영상 구조에 MV-HEVC 를 적용하면 객관적인 성능이 최대로 얻을 수 있음을 알 수 있었다.
