Butler Group Test and Measurement Opticom PEVQ Video Analyser
Opticom PEVQ Video Analyser
- PEVQ provides mean opinion score (MOS) estimates of the video quality degradation occurring through a network, e.g. in video telephony networks.
- PEVQ can be ideally applied to test video streaming, video conferencing and IPTV applications.
- The degraded video signal output from a network is analysed by comparison to the undistorted reference video signal on a perceptual basis.
- PEVQ is based on the approach to model the human visual system with which anomaly perceived in the video signal can be detected and quantified by a multitude of key performance indicators (KPIs).
- OPTICOM, the leading provider of signal based perceptual measurement technology for voice, audio and video, offers its new easy to use PEVQ V 2.0 measurement as an OEM solution.
- PEVQ evaluates the quality of CIF, QCIF, VGA and Rec. 601 video formats based on perceptual measurement, reliably, objectively and fast.
- PEVQ is based on the earlier PVQM technology developed by KPN Research and new develop-ments of OPTICOM.
