Subjective visual quality assessment in the presence of audio for Digital Cinema

Abstract

In this paper, we investigate whether the presence of audio with different quality levels can influence the outcome of subjective visual quality assessment in a Digital Cinema setting. We asked the participants to judge the visual quality when watching an audiovisual content in a Digital Cinema environment and investigated whether the participants can neglect the presence and the quality of audio. The stimuli used were 10 seconds long color sequences accompany with orchestral music at 2K resolution, 24 fps, and YCbCr 4:4:4 played on DCI certified equipment. The result show that in visual only subjective quality assessment, the presence of audio (low or high quality) does not significantly influence on the visual quality judgment.
