Video Clarity Introduces PEAQ for ClearView
Campbell, CA, April 11, 2011 – Video Clarity, Inc. today announced that PEAQ audio objective perceptual quality measurement is a new feature offered with the ClearView family of products. (http://www.videoclarity.com/products.html)
The ITU-R PEAQ (Perceptual Evaluation of Audio Quality) model is an "electronic ear" which performs an objective measurement of perceived quality of wideband (up to 20 kHz) audio signals using a computerized model of the human ear. This well accepted perceptual audio quality measurement method was developed jointly by experts from eight leading research laboratories and is an international ITU-R standard (ITU-R Recommendation BS.1387, "Method for objective measurements of perceived audio quality").
The PEAQ model processes two audio signals to be compared (namely the original reference signal and a test version to be evaluated)
and calculates a quality score similar to the mean opinion score that would be obtained from a formal subjective test.
The Video Clarity ClearView system provides a full implementation of the ITU-R PEAQ model which has been certified by the Communications Research Centre Canada, one of the laboratories that developed the ITU-R PEAQ method.
PEAQ is available with ClearView 7.0 coming in Q2, 2011
See a demonstration of PEAQ at NAB in Video Clarity booth SU7508 from April 11 through 14
ClearView is available direct from Video Clarity or one of our partners.
