30. w tektronix com Human viewer testing has been traditionally conducted as described in ITU R Rec BT 500 11 A test scene with natural content and motion is displayed in a tightly controlled environment with human viewers expressing their opinion of picture quality to create a Differential Mean Opinion Score or DMOS Extensive testing using this method can be refined to yield a consistent subjective rating However this method of evaluating the capabilities of a compressed video system can be inefficient taking several weeks to months to perform the experiments This test methodology can be extremely expensive to complete and often the results are not repeatable Thus subjective DMOS testing with human viewers is impractical for the CODEC design phase and inefficient for ongoing operational quality evaluation The PQA6OOA provides a fast practical repeatable and objective measurement alternative to subjective DMOS evaluation of picture quality System Evaluation The PQA600A can be used for installation verification and troubleshooting of each block of the 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 Not only can CODEC technologies be assessed in a system but any process that has potential for visible differences can also be assessed For example digital transmissio
