Research on Subjective Assessment Method of Ultra High Definition Video Quality

With the wide-spread use of digital videos, quality considerations have become essential, and industry demand for video quality measurement standards is rising. In this paper, we present the details of a subjective quality evaluation on 4K Ultra-High Definition (UHD) videos. We described the source sequences which were chosen and the preparation of the impaired test sequences. The test environment and test equipment was also presented and we chose DSCQS for 4K-UHD subjective quality assessment methodology. Based on the above analysis, a subjective assessment method of Ultra High Definition image quality was proposed.
