OPTICOM debuts PEVQ Analyzer
April 17, 2008
At NAB2008, OPTICOM is debuting its PEVQ Analyzer, an HD-capable video recorder with comprehensive perceptual audio and video analysis capabilities.
Perceptual Evaluation of Video Quality (PEVQ) measures the subjectively perceived quality of video sequences based on the five-point MOS (mean opinion score) scale widely used to characterize quality as perceived by humans.
Paired with OPTICOM’s ITU standard for audio quality analysis, the new device delivers audio/video quality metrics in the form of a pair of standardized MOS KPIs, even capable of tracking lip-sync artifacts.
PEVQ analyzes degraded video signals by a human visual model, representing true objective Quality of Experience (QoE) measurement. PEVQ provides an objective expert to assess IPTV performance issues in relation to incumbent TV satellite and cable services. For more information, visit
