This paper presents a novel method for fast and quantified estimation of the Perceived Quality of Service (PQoS) for MPEG-4 video content, encoded at constant bit-rates. Taking into account the instant PQoS variation due to the Spatial and Temporal (S–T) activity within a given MPEG-4 encoded content, this paper introduces the Mean PQoS (MPQoS) as a function of the video encoding rate and the picture resolution, and exploits it as a metric for objective video quality assessment. The validity of…

TLDR
It is shown how the perceived quality of service (PQoS) is introduced and exploited for quantifying purposes and how it can be further exploited towards proposing a technique for video quality prediction at a pre-encoding state.
A parametric model for perceptual video quality estimation
TLDR
A parametric model is proposed which provides estimation for the perceived quality of video, coded with different codecs, at any bit rate and display format, allowing a much better estimation of the perceptual MOS values, especially in low bit rate ranges.
Packet-Layer Quality Assessment for Networked Video
TLDR
To realize real-time and non-intrusive quality monitoring for networked video, a content-adaptive packet-layer model for quality assessment is proposed and achieves an advanced performance in comparison with the ITU-T G.1070 model.
