The true measure of any television system is viewer satisfaction. Based on the concepts of the human vision model, Tektronix Picture Quality Analyzers provide a suite of repeatable, objective quality measurements that closely correspond with subjective human visual assessment.

Picture Quality Analyzers are used for the design, evaluation and test of the encoding, transcoding and decoding processes. HDMI Testing is critical in today’s consumer electronics like Set Top Boxes and Blu-Ray players which output video through an HDMI interface with HDCP encryption. The PQA600B uniquely decodes the HDCP protocol, and enables video quality performance comparisons on a range of consumer electronics.

They can also 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.

The PQASW is the picture quality analysis software based on the concepts of the human vision system which provides a suite of repeatable, objective quality measurements that closely correspond with subjective human visual assessment.
