Mobile devices pixel density and video quality

Device screen size, design layout and resolution are some of the device context parameters which impact video quality on mobile devices. In this paper, through subjective tests, we evaluate the impact of mobile device pixel density on the video quality. We then, through the subjective test, propose a video quality model that takes pixel density into consideration. The proposed model was evaluated, and the preliminary results have shown that the proposed model performs well regarding correlation coefficient. The model has potential use for multimedia service providers such as YouTube and Netflix in areas of quality control and optimization of network and multimedia services.
