The CNN color lies: Same video but different colors ?

How do you know it was cnn that was a "lie"? Perhaps the other channels simply boosted color saturation to get a more appealing image?

I think the PAL -NTSC theory is probable. PAL video when converted to NTSC requires care on the part of the converter to maintain the proper color hue and intensity. If the person who ran the conversion was not comparing the originial to the converted copy, a loss of color intensity could very well happen..The conversion probably was done in haste, as it was news. In fact, it might not have even been done on broadcast quality equipment. News networks requently have to "make do".. Of course the Euro outlets did not need a color conversion.

I would expect the results would depend a lot on the conversion equipment and settings used, so I don't think you could "simulate" it in a way that would necessarily reflect what goes on upstream of you.

The digital transmission/compression issue is another possibility of course.

Does anyone know if the story about the color TV test setup with the bowl of fruit and some joker painting the banana green is true?

Color is not their only 'lie' G=B2

Probably both channels lied a bit.

France/Euro channels looked too colorfull.

CNN channel looked to dull :)

Bye, Skybuck ;)

Sorry, blue not green.

I've heard a lot of anecdotes about RCA's attempts to bring color TV to a practical state.. Some of them concern the frustration of color shift, particularly known colors of food, all of which wasn't solved very well for quite a while after NTSC color was deployed. The story you refer to I have never heard. I have heard of some altering of colors in early TV times to cause a picture to look better than it really was. It might have happened. The truth is, when NTSC color got the go ahead in '53, it really wasn't ready to get the job done, and, of course, we all know it got by on wink wink until later.

one of the US TV companies asked the BBC to send 100 engineers to help them to get colour working. The BBC offered the services of 2. One of the problems found, as told to me by one of those 2, was the transmission chain went through the 'loop-though' terminals of the video monitors.

But you've misunderstood the situation. The banana was painted blue to utterly fool the vision control engineer (BBC term) who aligned the camera to make it look yellow - with somewhat strange results on normal pictures.

The early sets had color & tint knobs in addition to brightness, contrast, and horizontal and vertical hold. They used to have fine tuning, as well.

I was dating a gal who had a big-screen projection TV, and it actually had "convergence" adjustments, probably because there are 3 monitors in the thing.

When we got our first color set, the guy said to adjust the color knobs until the fleshtones (skin) are acceptable.

Cheers! Rich

I worked on many TVs with convergence controls. You needed a "dot / bar" generator to use them, i built my own, also a degaussing coil. The color controls were also called hue and saturation back then. I would even fiddle the "purity rings" if i found it necessary. All that is gone now.

No, but I've seen the Indian Head Test Card where the Indian was in color, propped up in front of a B&W camera. Does that illustrate "some loss of color information may occur"?
