What’s New: HD Video Quality Tests

Intel® DHCAT 3.0’s use of perceptual models make it unique among PC platform evaluation tools, since it focuses on quality of experience, and creates a kind of “jury test in a box.” But it’s still useful to put one’s own eyes to some video test material and judge for oneself the quality of video playback. So in Intel® DHCAT 3.0, we’re adding subjective HD video tests where you’ll get instructions on what issues to look for with video quality, be shown a video clip, and then you can rate that clip based on what you just saw. These tests aren’t part of the Intel® DHCAT 3.0 overall score, but are tests you can run if you want to on your system to see its HD video playback capabilities firsthand.

Here are a few screenshots from these upcoming tests:

Windmill: This video clip looks at interlacing artifacts, such as “combing,” which is visible in the windmill blades.

Moving Alphabet: This video test looks at scaling artifacts, which become visible as the letters scroll by horizontally.
