This device performs automatic, real-time video quality evaluation of SDTV.
The VP21S achieves automated, real-time video quality measurement and
picture quality analysis by comparing the source and the tested video.
Our patented Video DNA Technology gives video quality evaluation that
highly correlates with subjective testing according to ITU standards (DSCQS*). Video synchronization is done
automatically by the equipment, and analysis is done at
pixel level of detail. VP21S is mainly used for CODEC
evaluation, QA verification and SDTV system performance
improvements.
- Encoder/decoder debugging operations
- Broadcast system video quality evaluation
- Automatic dubbing video quality evaluation
- Evaluations of encoding quality/performance during DVD authoring
- Automatic evaluation of master DVD playback quality
- Video Input/Output (no need for PC connection for evaluation)
- Automatic video synchronization without special markers
- High correlation to subjective testing (DSCQS) (0.9)
- Uses animation to caption generated noise (Option)
* Double Stimulus Continuous Quality Scale: This method
has been standardized under ITU-R (International
Telecommunications Union-Recommendation). Under this
method, picture quality is expressed as a percent from 0 to
100 with 0 indicating no distortion.
