Abstract
A method for assessing the quality of a transmitted video signal sequence at the receiver side includes the steps of: capturing the received input video bit stream prior to decoding and supplying it to a video bit stream analyzer; extracting, during a measurement time window, one or more features from the captured packet headers by the bit stream analyzer, without analyzing or decoding the packet payload; computing from the one or more features, a single parameter, xwpSEQ, representing an estimate of the spatio-temporal extent of the signal degradation due to packet-loss; supplying the determined parameter to a quality estimation module; and calculating, by the quality estimation module, a quality measure due to packet loss (Q) based on the single parameter representing the estimate of the spatio-temporal extent of the signal degradation, xwpSEQ, due to packet-loss and based on video resolution information and employed video codec.
