QA
Capture, Align, Compare, Pass/Fail, Repeat
How do you know whether your quality is the same machine-to-machine? Do you know why the customer RMA-ed your unit back? ClearView QA captures the video output, aligns it with a known “gold” source, compares the 2 sequences, and reports pass/fail results outside of threshold. This solution is completely automated using our scriptable interface or it can be run interactively from a GUI.
ClearView QA is a 2RU Automated, Quantitative Video Analyzer, which is an end-of-line automated functional tester to ensure the quality of complex digital encoders & receivers used for terrestrial, cable, and satellite broadcast systems.
