The new

PEVQ Analyzer

evaluates the quality of

multimedia (QCIF, CIF, VGA), SD and HD video for-
mats based on perceptual video quality-of-
experience measurement, reliably and objectively.
The system allows for synchronous SD and HD
play-out and recording over a range of interfaces
(HD-SDI, DVI) and comes with a high-perfor-
mance, front accessible array of hard disk drives.

Perceptual Evaluation of Video Quality (PEVQ) is
an accurate, reliable and fast video quality meas-
urement 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 telepho-
ny, video conferencing, video streaming, and IPTV
applications.

PEVQ is a full-reference, end-to-end measurement
based on signal analysis: The degraded video sig-
nal output from a network is analyzed by compar-
ison 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 manufac-
turers, network operators and service providers

can analyze QoE issues and optimize next genera-
tion networks and thus avoid customer's dissatis-
faction, which otherwise might lead to complains
or churn.

OPTICOM, the leading provider of signal based
perceptual measurement technology for voice,
audio and video, offers its new easy to use PEVQ
testing technology in combination with its proven
audio

quality

analysis

techniques

PESQ

(Perceptual Evaluation of Speech Quality) and

PEAQ

(Perceptual Evaluation of Audio Quality).

The combination with these state-of-the-art test
algorithms allows for audio-visual quality analysis
and thus provides useful means for lip-sync arte-
fact measurement.

Users can choose among the PEXQ software suite
for Windows™ and the PEVQ Analyzer. PEVQ is
also available as an OEM solution and has been
adopted by a range of leading industry partners
(see www.pevq.org for further information on
third parties' product availability).

PEVQ is based on the earlier PVQM technology
developed by KPN Research and new develop-
ments of OPTICOM. The PEVQ analyzer is pro-
duced in cooperation with DVC Germany
(www.digitalvideo.de).

PEVQ has been verified by the Video Quality
Experts Group in 2008 and is going to be proposed
for International Standardization.

Key Features:

• Accurate, reliable and fast

objective analysis of per-
ceived video quality

• Full reference based end-

to-end quality analysis

• Outputs MOS score

that correlates well
with subjective MOS

dia (QCIF, CIF, VGA), SD
and HD video quality

• Applications: IPTV, stream-

ing video, 3G, video
telephony

• Performance verified and

recommended for stan-
dardization by the Video
Quality Experts Group
(www.vqeg.org) 2008
