Abstract

QoE metrics are a must in new service evaluations as they have shown to outperform traditional QoS. This work presents a flexible framework for measuring different types of QoE analysis and capable of synchronizing reference sequence with distorted videos for avoiding erroneous coupling. We define cPSNR metric, a measurement system suitable for performing the evaluation of transmission impairments exclusively, from the perceived quality perspective. The metric is validated with a subjective video database showing a promising correlation with both packet loss ratio and subjective quality.
