digital waves as well.
I can only comment on the above portion of this ridiculous post.
All broadcasts follow red blue green frequencies? What the hell does that mean? Let's have a little lesson on color, shall we? And please, someone
feel free to elaborate as I may come up short on my explanation.
There are two types of color I will talk about. The first is the type you see when you look at a painting or a photograph. Physical media like these
produce color by reflecting light from a light source back to the eye. If you see something that looks green, the media is absorbing all of the
visible frequencies except green. Reflected color is referred to as "subtractive" color. This means that you start off with primary colors, then
as you add other colors, the media (paint) becomes darker. Red and blue make purple. Yellow and red make orange. Red, green and blue make brown. Got
Now, televisions reproduce colors by projecting light from a light source. That light source is filtered through picture elements (pixels) of three
primary colors: Red, Green and Blue. Projected color is ADDITIVE. This means that if you mix red, green and blue together at the same intensity, you
get WHITE light. Also, some newer HDTVs are adding a yellow pixel to the color space to reproduce yellows better, which has always been a weakness of
the RGB color space. Anyway. Both CRTs and flat screens reproduce color the same way. The only difference is in the mechanical assemblies used.
Digital or analog - it's still the same.
I have no idea what the OP is trying to say, and it makes absolutely NO sense. If sunlight is reaching earth in a slightly shifted color spectrum
than last year, it wouldn't make a damn bit of difference to a TV set. If something is happening, I would think that it would affect TVs, and it
Man I am getting off track, but i just want to know who is giving this thread so many stars and flags?
As a postscript, Broadcast TV went digital for several reasons: It's better picture quality; It uses less RF spectrum; You can squeeze digital
channels closer together in the RF spectrum with no crosstalk. Analog was hogging so much spectrum that there was no room left for new wireless
devices - cellphones, crackberries, new devices yet to hit the market. Also, for many years TV stations were simulcasting in analog AND digital,
hogging even MORE spectrum. Once they killed analog broadcasts, it opened up huge blocks of spectrum for these new devices. And it all has nothing to
do with the world shifting frequencies, which is one of the most ridiculous theories lacking in any proof that I read on this site. Seriously, there
is more evidence of UFOs and Jesus having risen from the dead than this new age baloney.
