Abstract
An audio and/or visual transmission quality device estimates transmission quality as perceived by a user based on observation and processing of objective metrics. The device preferably includes a primary integrator to generate an instantaneous estimate of user annoyance based on occurrence of frame loss events in a received signal. The device further preferably includes secondary integrators to process the instantaneous estimate of user annoyance in selected time intervals and generate a plurality of time-varying estimates of user annoyance valid over the selected time intervals. The device may further include a plurality of scaling modules to scale the plurality of time-varying estimates and generate a corresponding plurality of estimates of transmission quality as perceived by the user. The device may further include a modulation network to modify a sensitivity of the primary integrator to the occurrence of frame loss events in the received signal.
