Abstract
A subjective quality monitoring system for packet based multimedia signal transmission systems estimates the parameters of a statistical model representing the probabilities of said packet based transmission system being in a low loss state or a high loss state and uses said estimates to predict the subjective quality of the multimedia signal. The quality monitoring system comprises a plurality of quality monitoring functions located at the multimedia to packet conversion points.
