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

on a field by field basis
- 1080i/720p/480i@59.94Hz 576i@50Hz
- Easy to operate GUI or monitor display
- Customized monitoring parameters
- RS232C Output (Date logging with time code
on PC file)
- Double Stimulus Analysis to 0.9 accuracy (ITU-BT.500.8)
