QC in a 3D world

摘要

I have written in the pages of this magazine before about my belie that quality control is just as important in the digital era as it was back in analogue days. We still have to make the best we have of the available colour gamut and audio dynamic range, and we sti have to ensure consistency between sources. In one important way, digital measurements are even more critical because we have no warning when something is going to fail. Analogue signals degrade; digital signals either work or they do not.
