Understanding the perceptual impact of compression artifacts in video is one of the keys for designing better coding schemes and appropriate visual quality control chains. Although compression and transmission artifacts, such as blockiness, blurriness, and packet-loss, appear simultaneously in digital videos, traditionally they have been studied in isolation. In this paper, we report the results of three subjective quality assessment experiments aimed at studying perceptual characteristics of a set of artifacts common in digital videos. With this goal, first, we study the annoyance of each of three artifacts (blockiness, blurriness, and packet-loss) in isolation and then in combination. Based on the subjective evaluations, we design several models of the annoyance caused by the joint presence of these three artifacts on digital video.
