Abstract

This paper deals with the notion of user satisfaction relative to the consumption of modern encoded video applications and services. Due to the process of encoding/compression of a video signal, respective quality degradation takes place, which in turn introduces the need for quality assessment methods and procedures. The objective of this paper is to research the impact of the spatiotemporal dynamics of the video content on the deduced perceptual quality. More specifically it is presented how the spatiotemporal activity affects i) the highest quality level that each video can reach, ii) the video quality acceptance threshold such as the lowest quality level and iii) the video quality vs. bit rate pattern.
