The Effect of Spatiotemporal Tradeoff of Picture Patterns on QoE in Multi-View Video and Audio IP Transmission
説明
In this paper, we study QoE (Quality of Experience) of Multi-View Video and Audio (MVV-A) transmission over IP networks. This paper assesses the effect of the tradeoff relationship between improvement of image quality and degradation of viewpoint change response owing to the picture patterns. When the length of GOP (Group of Picture) is short, the viewpoint change response is quick, but the image quality is not good. On the other hand, in the long GOP, the image quality is good owing to high coding efficiency, while the viewpoint change response is slow because the new viewpoint cannot be shown until receiving the next I picture. We employ two contents and assess QoE multidimensionally by a subjective experiment.
