This paper presents a subjective video quality study of video sequences coded using the scalable extension of the H.264 standard (SVC). A group of experiments was performed to measure, primarily, the effects of transmission instability and the influence of the three scalability methods (spatial, temporal and quality) on the video quality. The definitions were based on a layered transmission system using protocols for adaptability and congestion control. To run the subjective assessment we used the ACR-HRR methodology and recommendations given by ITU-R Rec. BT.500 and ITU-T Rec. P.910. The results show that instability does not causes significant alterations on the overall video subjective quality and that the temporal scalability usually presents far lower subjective quality than spatial and quality scalabilities. |
