Product Overview
The Video Quality Analyzer VISUALmpegVQA, as a part
of the complete MPEG stream analyzer product range VISUALmpeg, offers
several measures for video quality and covers the detection of a broad
range of video distortion and quality degradation. VISUALmpegVQA can
be used as an automated analysis system for codec quality analysis.
Checking your MPEG and H.264 file quality thereby becomes an automated,
easy to use process with clear reporting functionality. The system works
without knowledge of the original signal (no reference system). This
feature offers the advantage of analyzing any encoded and received stream
without making use of the source signal. Using extensive video quality
assessment algorithms, the VISUALmpegVQA utilizes MPEG stream parameters
as well as the decoded video signal. Main feature of the quality assessment
unit is the video MOS (Mean Opinion Score). VISUALmpegVQA analyzes an
MPEG stream and provides a mean opinion scoring. The scoring correlates
highly with the subjective impression of the viewer.
