Summary:The paper deals with the video codecs of the MPEG family. In a large-scale study, these codecs are compared with one another using a numerical tool (QoE) and a real study in which test subjects present their user experience (UX). The typical impairment parameters of the IP transport platform, i.e. packet loss and burst factor are taken into account. The encoding rates for the video content also play an important role here. In the study, the advantages and disadvantages of these video codecs are analyzed in depth on the basis of the test results, which are graphically displayed in several diagrams. Furthermore, parameterized QoS models are determined for the video codecs considered in this paper, and their effectiveness is also assessed. These QoS models are based on a protocol analysis of the video stream. They are very simple, can be carried out quickly, and are therefore very suitable for practice.
