Correlating Objective Factors With Video Quality Experienced By End Users on P2PTV

摘要

To succeed in providing services, the quality of services should meet users’ satisfaction. This is amotivation to study the relationship between the service quality and the real perceived quality of users,which is commonly referred to as the quality of experience (QoE). However, most of existing QoE studiesthat focus on video-on-demand or IPTV services analyze only the influence of network behaviors to videoquality. This paper focuses on P2P video streaming services, which are becoming a significant portion ofInternet traffic, and pays attention to the change of users’ perception with the adjustment of objectivefactors as well as network behaviors. We propose to use mean opinion score and peak signal to noise ratiomethods as QoE evaluations to consider the effect of the chunk loss ratio, the group-of-picture size, and thechunk size. The experimental results provide a convincing reference to build the complete relationshipbetween objective factors and QoE. We believe that this assessment will contribute to study a new servicequality evaluation mechanism based on users’ satisfaction in the future.
