Monitoring Video Quality Inside a Network
We consider the problem of evaluating the quality of transported, compressed video from the perspective of a network service provider. Traditional video quality metrics require original and decoded pixels to be available. However, neither are easily available inside the network. Therefore, we have developed no-reference techniques
that estimate visual quality, relying only on (potentially lossy) bitstreams available inside the network.
In this talk, we present an overview of the problem with measuring video quality in the network and present two quality metrics for broadcast MPEG-2 video.
