1080 – 24P – 60P – 120Hz – 240Hz – 480Hz
So you're about to buy a new 1080p flat screen TV, upgrade your home theater system and one of the many confusing terms that you see on all these TVs are 24P, 60P, 120Hz and 240Hz. And this is not the end of it. 480Hz is the immediate horizon and there is little plasma television touting "600Hz Sub-field unit.
Well, as almost everything in life is not what you do, is how you do. 600 is only better than 60 if you do well.
A little background if you're not a videophile. 24P means 24 frames per second (fps). This image is often more Hollywood films roll in. So every second of film is 24 individual images. TV is a little different. Most TV programs are filmed at 30 frames per second. The officials will tell you that there are good reasons for the difference, but they are full of shit. They did to screw us.
The difference between 24 and 30 frames per second was a big problem when CRT "tube" TV, because they suck, but now with today's television, there is a password to suck a little less. TV today have no problems switching between 24 and 30 fps, but even if you read 24fps, since is supposed to be, seems a little nervous. Well, the people who make television are more intelligent than the people who make the movies we see, right? By course they are. So he decided to screw around and gives us 120Hz.
Indeed, Hz is the abbreviation for Hertz, which is a measure of frequency in a second. Is the name the German physicist Heinrich Hertz. The road was smart back when the girls thought it was cool to be smart. If you did not graduate from the frequency of major media how often something happens during a given period. The speed at which the Earth orbits the sun is measured at a frequency of call a year.
Thus they now know the frequency, you know that Hertz and frames per second are the same thing, so 24 fps = 24 Hz, right? Wrong. The reason they call Fps Hz, and no, it's because not really unique show 120 images per second. They have only 24 or 30 original images every second, increasing the pinch of time then they, the insertion of a few all frames of "deep black" here and there and make this whole mess of shit are added 120. So there is a shred of honesty in the "120Hz", a nickname, but I think it was done on purpose.
So now we are friends, and you know I'm not BS'ing you can reveal a little secret. 1080/60P really 1080/30p, and almost every time you see 1080P Plain Old TV, they mean … 60P 30P, or rather because are taking only the picture frame 30 and shown twice. Although little trick that gave them an idea.
Since there is no good way to convert 24fps Hollywood TV Land 30fps without bending each image 4 (also known as 3:2 pulldown), causing Judder, television makers recalled a tour of her class of 4th graders mathematics called the "least common multiple." Guess what is the LCM of 24 and 30? Yes, it's 120. Go to 120Hz is the whole image processing much more easy. For 24fps film sources that have 5 cycles to work each image and video sources at 30fps, have 4 rings. To enjoy it, simply can flash the same image of 4 or 5 times, you can insert black frames in total mix, or if they have much video processing power, which in fact can interpolate intermediate frames smooth the movement.
Most manufacturers have a mix of all these options and to make your own recipe to create the image of 120Hz. Some do it better than others and some are just plain bad. But in my opinion, none of which have improved 120Hz However, I am puzzled by the new state and 240Hz and above 480Hz, which is accessible at any time. Most LCD televisions are technically unable to display only 480 images, even in a second, even good. Required 2 millisecond (2 ms) response time (1 / 480 = .002), which is not impossible, but certainly not common in the world of LCD TVs. Just a few years ago, a time 8ms response was a big problem.
Now there are some plasma sets mark in the various forms of marketing taglines 600Hz, but most are not so advanced in terms of video processing as the best 120 or LCD TVs 240Hz. I'm sure there's some technicality that allows them to legally call it "600Hz subdural hematoma or other reasons, but above all it is marketing.
