The Secrets Blu-ray Player HDMI Benchmark - Part I


Why This Matters

Your first question might be, "Why does it matter if the color conversion isn't quite perfect?" or, "I don't know how to choose a color space, so why would this affect me?"

These are very valid questions, so let us look at what could happen. From the players we have analyzed so far, if your player does incorrect color conversion, you can suffer from many issues including:- A loss of dynamic range in your image. Outdoor scenes won't be as bright as they should be, and night scenes won't be as dark. Image information will be squeezed closer together and not appear as it should be.

- Colors will appear incorrectly from your Blu-ray player compared to HDTV. The color of red from your Blu-ray player won't be the same as your color of red from other HD sources, even if your display has been calibrated.

- You can lose resolution in color or black and white that should be there. Artifacts might appear that shouldn't be there, blue skies can suffer from banding instead of being smooth, and color transitions won't happen correctly, resulting in abrupt changes instead of being gradual.

- Data that you should be receiving might be clipped off incorrectly, or data that you shouldn't get might be visible when they should be hidden.

In short, you will never get the full performance from your system, no matter what you do, if the color conversion and color space selection is incorrect. Note, however, that most Blu-ray players deliver a picture that is good, in general. The color errors that we will report on in our Benchmark reviews are not defects that jump off the screen. Otherwise, the manufacturer would have noticed them and fixed the problems. The function of our Benchmark is to show not only our readers, but the manufacturers, where errors are found, so that they can be corrected in future models.
