Video Quality Assessment from the Perspective of a Network Service Provider

In this paper we consider the problem of estimating the quality of a decoded video that is transmitted over an unreliable packet-switched network. The goal is to allow the encoder to calculate the expected decoder distortion without any direct comparison between the original and the decoded sequence. This work is based on ROPE algorithm for the video quality estimate. ROPE calculates, at the encoder side, the expected decoded video distortion: therefore it is reasonably performing in estimating the average obtained distortion. The main question this paper would like to answer is how accurate ROPE distortion estimate is in the case of a single realization, i.e., in the case of distortion estimate for a single user
