Abstract

A method for measuring quality of packetized audio and video transmission over a transmission chain includes: providing one or more measurement detectors along the transmission chain; detecting, by the one or more measurement detectors, loss of bit stream packets at one or more measurement points; determining the unique identifier for each detected lost packet; sending, by the one or more measurement detectors, a list of lost packet identifiers to a central monitoring system; constructing, by the central monitoring system, a simulated stream for each measurement point based on a stored error-free stream and the received lost packet identifiers; and evaluating the simulated stream for deriving a quality score for each measurement point.
