High Definition and Standard Definition Baseband Picture
Quality Measurement and Video Quality Analysis Device. The VP21H is a
powerful high-picture quality measurement and analysis device for
Baseband Video (HD/SD SDI).
 The
VP21H achieves automated, real−time picture
quality measurement and
analysis by comparing the source and the tested video.
Our patented “Video DNA” Technology gives objective
evaluation that highly correlates with subjective
testing according to ITU-DSCQS* standards (see ITU
Recommendation J.144). Video synchronization is done
automatically and video quality analysis is at the pixel level. The
VP21H is ideal for CODEC evaluation, Quality Control and
HDTV/SDTV system performance improvements.
