Pass/Fail Automated Video Quality Testing

Automated Video Quality Testing

Steps for Pass/Fail Automated Video Testings

  • Use a Preloaded Uncompressed Test Patterns or Load Your Own

  • Play the Test Pattern to any Digital or Analog Device-Under-Test (DUT)

  • Input any File or Record from the DUT's Output

  • Automatic Temporal and Spatial Alignment

  • Compare Video Quality to a "Gold Sequence"

  • Automated, Scriptable Pass/Fail Video Quality Testing

  • Log & Graph the Pass/Fail Results

  • Subjectively View 2 HD Video Sequences to Verify Score

Tools to Help You Every Step of the Way

After the video is scored using Sarnoff JND or your own "golden eyes", this score can be compared for regression testing against any number of units. The known score will be termed "Gold". In this case, ClearView aligns the two video sequences and compares their video quality. Any video sequence, which scores below a user specified threshold, will generate a failure.

The metric data is archived into small log files. These log files can be replayed on any ClearView machine with access to the original video sequences, which ensures a repeatable test environment when anomalies are resolved. Further, these log files can be added to the regression testing to ensure that the anomalies stay fixed. For additional convenience, our analysis and graphing tool kit imports these log files into Microsoft Excel for off-line viewing.
