measurement and analysis tools for picture quality in a single product. It
is unique in its ability to make comparisons among different file or video
formats, frame rates, viewing conditions and display models. Engineers who
are testing the picture quality of their AVS encoders and decoders are able
to more quickly complete an optimized design for a targeted viewing
environment. In 2007, PQA500 was selected by Cable & Satellite International
Magazine and the International Association of Broadcasting Manufacturers for
"Innovation at its Best."
“China is the largest television producing and consuming country in the
