Assessing quality of experience for high definition video streaming under diverse packet loss patterns

This paper presents an approach for deriving a QoE model of High Definition video streaming in the presence of different patterns of packet losses. The goal was achieved by using the SSIM video quality metric, temporal pooling techniques and content characteristics. Subjective tests were performed in order to verify the proposed models. The impact of several network loss patterns on diverse video content was analysed. The paper also deals with the encountered difficulties and presents intermediate steps to give a better understanding of the final result. The research aims to evaluate the perceived performance of IPTV and video surveillance systems. The model has been evaluated in the Quality of Experience (QoE) domain. The final model is generic and shows high correlation with the subjective results.

► The metric includes spatial activity, number of separate losses, and the SSIM averaged over the worst second.
► All the input parameters are statistically significant; temporal activity is insignificant.
► Predicted MOS values are highly correlated with the observed ones across diverse content and losses.
► Technical problems of HD video streaming in a non-professional HRC are discussed.
► Subjective test approach based on ITU-T recommendations is presented.
