Abstract

In this paper, the subjective video quality assessment of the content quality was to examine by the assessors about the three content quality of HD, Up-scaling UHD, 4K UHD Native that is currently broadcasted. The comparative assessment was conducted using three types of TV sets, 55, 65, 75 inches, at a distance of 2.5 meters which is the distance of watching TV in general households. Among the participants who took part in the video quality evaluating experiment and the questionnaire survey, the answering data of the final 169 persons were adopted after removing the data of 4 persons who answered inadequately in the evaluation of the video quality. The effects of gender, preference of program genre, size of TV sets were analyzed statistically using SPSS 25.0 analysis package. In addition to these, the objective video quality assessment through the measuring instrument was performed, and compared with the results of subjective video quality assessment.

본 논문에서는 현재 방송 중인 Full HD, Up-scaling UHD, 4K UHD Native의 세 가지 콘텐츠품질을 대상으로 일반 가정의 TV 시청거리인 2.5m 거리에서 55, 65, 75인치 세 가지 크기의 TV수상기를 이용하여 주관적 화질평가를 실시하였다. 본 화질평가 실험은 화질평가 응답이 부적합한 4명의 데이터를 제외한 169명의 데이터를 대상으로 SPSS 25.0를 이용하여 콘텐츠품질이 성별, 수상기 크기, 선호프로그램 장르에 따른 영향을 분석하였다. 또한 측정기를 통한 객관적 화질평가와 주관적 화질평가 결과도 비교 분석하였다.
