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 proposed a no reference video quality metric for 4K-UHD videos in the compressed domain. As video coding parameters which can reflect the degree of distortion caused by compression can be extracted in compressed domain, we firstly extracted some feature parameters from 4K-UHD compressed videos. Then the parameters were applied to train the proposed model with the corresponding subjective score using multi-linear algorithm. The experimental results show that our model can achieve a good performance for the 4K-UHD video streams with the subjective score. Keywords-4K Ultra High Definition; subjective video quality assessment; no reference; objective video quality assessment; compressed domain
