Subjective quality assessment of mobile 3D videos

With the development of mobile network and 3D display technology, watching 3D videos on portable devices through mobile network is to be a trend. In this paper, we study the influence of Quantization Parameters (QP), resolution and packet loss on the QoE of mobile 3D videos. Side-by-side formatted 3D video sequences of different QP and resolution, transmitted through networks of different packet loss ratios (PLR) are produced, and two subjective assessment experiments have been made on two portable devices. Each video sequence is tested according to four measures, including clearness, depth perception, comfort level and overall quality. The results show that QP and resolution have a greater impact on mobile 3D videos´ clearness than depth perception and that the influence of packet loss is not as stable as the other factors.
