Perceptual Evaluation of Video Quality (PEVQ) is an accurate, reliable and fast video quality measurement technology, developed by OPTICOM. It provides mean opinion score (MOS) analysis of the video quality degradation occurring through a network, e.g. in mobile and IP-based networks. PEVQ can be ideally applied to test video telephony, video conferencing, video streaming, and IPTV applications.

PEVQ is a full-reference, end-to-end measurement based on signal analysis: The degraded video signal output from a network is analyzed by comparison to the undistorted original reference video signal on a perceptual basis. Based on the approach to model the human visual system, PEVQ can detect anomalies in the video signal and quantify them by a multitude of key performance indicators (KPIs). With PEVQ one can analyze the video quality based on a human visual model, thus representing the true image quality as perceived by subjects, for example paying subscribers. Its value proposition is obvious: equipment manufacturers, network operators and service providers can analyze QoE issues and optimize next generation networks and thus avoid customer's dissatisfaction, which otherwise might lead to complaints or churn.

• Accurate, reliable and fast objective analysis of perceived video quality

• Full reference based end-to-end quality analysis

• Outputs MOS score that correlates well with subjective MOS

• Additional KPIs for detailed analysis

• Measurement of multimedia (QCIF, CIF, VGA), SD and HD video quality

• Applications: IPTV, streaming video, 3G, video telephony

• Performance verified and recommended for standardization by the Video Quality Experts Group (www.vqeg.org) 2008
