ABSTRACT. This paper presents an assessment method for fast and quantified estimation of the Perceived Quality of Service (PQoS) for homogeneous MPEG-4 video content, enabling optimized utilization of the corresponding storage and bandwidth resources. Besides, the Mean Perceived Quality of Service (MPQoS) as a function of the video encoding rate is introduced and exploited as a metric for objective video quality assessment. The validity of this metric is evaluated by comparing PQoS experimental curves to the theoretical benefit functions. Based on the proposed metric the paper presents a method for pre-encoding PQoS assessment based on the fast estimation of the S-T activity level for homogeneous MPEG-4 video content, encoded at constant bit-rate.
