The true measure of any television system is viewer satisfaction. Based on the concepts of the human vision system, the PQA500 provides a suite of repeatable, objective quality measurements that closely correspond with subjective human visual assessment. The PQA500 can be used for installation, verification and trouble-shooting of each block of a video system because it is video technology agnostic; any visible differences between video input and output from processing components in the system chain can be quantified and assessed for video quality degradation.
