There's a lot of talk these days about frame rates in the new Hdtvs. The frame rate is simply the number of positive images a Tv screen can display in a second, and is also known as the display rate or "Hertz". Hertz is the scientific unit for cycles per second, and is abbreviated "Hz". The latest buzzword is "120Hz", which means a display rate of 120 frames per second. This is twice as fast as most Hdtvs are capable of (60Hz), so it ought to make the exciting pictures look smoother. But, the human eye can only process about 20 to 25 positive images per second, so why should it matter what the frame rate is, as long as it is faster than your eyes can see?
The retort comes when you realize that not all video is filmed at the same rate. Movies are usually filmed at a rate of 24 Hz, most Tv is filmed at 30 Hz, and some sports events are now being filmed at 60 Hz.
Vizio Audio Problems
Some uncomplicated math will show the problem and relate the solution. When a Tv set wants to display 60 frames per second, and the cable Tv company sends it 30 frames per second, that's easy to deal with: the Tv shows each frame twice in a row, creating an image made up of two consecutive frames. Each image will last exactly 1/30th of a second on the screen, and things will look perfectly smooth.

So what happens when your Dvd player sends 24 frames per second to the Tv, but the Tv still wants to show 60 on the screen? This is a itsybitsy slower than the cable Tv frame rate, so if it simply shows each frame twice and then waits for the next one, there will be a black gap in between and the movie will look terrible. So, the Tv needs to triple one frame, duplicate the next, triple the following one, and so on, giving it a total of 60 frames to show each second. This is known as 3:2 Pulldown.
The 3:2 Pulldown trick works Ok, but there is a problem. One image lasts a 20th of a second, then the next lasts a 30th. A 20th of a second is long adequate for most people to tell that it's actually a static image, and when the camera pans nearby in a scene, things will seem to move unevenly. But if your Tv is able to display 120 frames per second, it can take the 24 Hz input and simply show each frame 5 times in a row for a total of 1/24 (or 5/120) second per frame, with no divergence from frame to frame. And when 30Hz video comes in, it displays each frame 4 times in a row, for a total of 1/30 (or 4/120) second per frame. Problem solved.
Now that frame rates are fast adequate to display any kind of input smoothly, Hdtvs not only have high resolution in the x and y (height and width) dimensions, but also in the t (time) dimension. As in all kinds of digital media, higher resolution means smaller units of data, and that means a more lifelike reproduction of reality. The 120Hz frame rate won't be very common until 2008, but a few Hdtvs already have it, like the Sony Bravia Xbr4 series and the Sharp Aquos 92U series.
Hdtv has actually entered the fourth dimension (time), but has skipped the third (depth) in the process. Until we see start seeing holographic movies on Dvd, we'll have to wait for true four-dimensional Tv.
Hdtv Enters the Fourth dimension - 120Hz Frame RatesFacebook Parenting: For the troubled teen. Video Clips. Duration : 8.38 Mins.Warning: Since this video seems to have gone crazy, I figure I'll post this notice. I'm going to read a letter my 15 year old daughter wrote. There ARE some curse words in it. None of them are incredibly bad, but they are definitely things a little kid shouldn't hear... not to mention things MY KID shouldn't say! If you want to see the original Facebook thread, it's located at: www.facebook.com ---------------------------------------------------------------------------------------------- My daughter thought it would be funny/rebellious/cool to post on her Facebook wall just how upset she was and how unfair her life here is; how we work her too hard with chores, never pay her for chores, and just in general make her life difficult. She chose to share this with the entire world on Facebook and block her parent's from seeing it. Well, umm... she failed. As of the end of this video, she won't have to worry anymore about posting inappropriate things on Facebook... Maybe a few kids can take something away from this... If you're so disrespectful to your parents and yourself as to post this kind of thing on Facebook, you're deserving of some tough love. Today, my daughter is getting a dose of tough love. © Copyright 2012, by Tommy Jordan. All rights reserved. Duplication without express permission of the author is prohibited.
