양안식 3DTV 비디오의 효율적인 압축을 위해 다양한 기술들이 연구되었으며, 그 중 좌우영상으로 상이한 해상도의 영상을 사용하는 비대칭 양안식 영상은 인간의 시각시스템이 상이한 해상도의 양안식 양상을 높은 쪽 영상의 품질에 가깝게 인지하는 특성을 이용한 대표적인 비트레이트를 절감 방식이다. 이에 다양한 연구에서 좌우해상도 차이에 따른 화질 저하 정도를 측정하려는 시도가 이루어졌으나, 기존 연구에서는 적정 시청거리를 고려하지 않고 좌우 영상의 크기만을 고려하여 실험하였으며 따라서 각 연구별로 상이한 실험 결과가 도출되었다. 본 연구에서는 인간의 시각 시스템을 고려하여 적정 시청거리를 계산하고, 이에 따라 좌우영상 비율 별 화질평가를 수행하였다. 특히 본 연구에서는 좌영상을 IID급 방송콘텐츠로 가정하고, 우영상을 모바일 방송콘텐츠로 가정함으로써, 실험 결과의 방송 서비스 활용가능성을 높였다.
