Rethinking standards in the media world
Bruce Devlin It's actually a more difficult question than you think. When I ask the majority of engineers this question, I will get a technical answer. It will be something like "to be sure we meet the specification" or "to be sure we don't put bad signals on air" or "so that I don't get fired for getting loudness wrong"

Watch out for dead pixels
N/A A dead pixel in a camera imaging sensor can manifest itself in a number of ways. Implying black, 'dead' is not necessarily the correct term for a pixel failure. This is because imager defects include hot pixels, sparkles, noisy or lazy pixels. These problems usually arise during the chip manufacturing process.

Gamut errors: Who cares?
N/A Gamut errors are the most common video signal problems. This is because colour television or cinematography depends on being able to represent every pixel on the screen in terms of red, green and blue. We want to deliver perfect RGB signals representing all the possible colours in our pictures. Virtually all display technologies use RGB primary colours to match the RGB colour sensitivities of the human eye. A gamut error occurs if we process video from a non-RGB colour space which overloads or creates negative value in one of the RGB channels.
