5, 5PEVQ™ Analyzer PEVQ MOS The PEVQ MOS value lies within a range from 1 (bad) to 5 (excellent). The PEVQ MOS is based on a multitude of percep- tually motivated parameters. Distortion indicators For a more detailed analysis the percep- tual level of distortion in the luminance, chrominance and temp…
