A monitoring device includes a video buffer model and a user model. The video buffer model monitors a media program streaming across a network to a media client for perceivable transmission impairments. The user model reflects user dissatisfaction due to types of perceivable transmission impairments and timing, duration, and frequency of perceivable transmission impairments so as to estimate a quality of experience of the media program. The parametric model can include one or more parameterized functions, and a set of parameters used in at least one of the one or more of the parameterized functions at a point in time during the streaming of the media program can be based on a type of perceivable transmission impairment associated with the point in time.
