International audience. Most of studies on video quality assessment are focused on the impact of coding distortion or transmission error. In this paper, display is considered. Regarding technology, some subjective experiments suggest that there are differences in term of quality between LCD and CRT. CRT provides a better quality when viewing HD video content while it is LCD when viewing still colour images. One explanation of this behaviour is explained through the LCD motion blur. From a motion blur perception model, an efficient metric of the quality loss due to this effect on LCD is proposed. Finally, the results of subjective experiments using SD video content are consistent with a motion-blur-based model and point out that the effect of display technology is linked with the video resolution.
