Hdtv Enters the Fourth dimension - 120Hz Frame Rates

There's a lot of talk these days about frame rates in the new Hdtvs. The frame rate is plainly the amount of unavoidable 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 newest 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 unavoidable 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 sass comes when you perceive that not all video is filmed at the same rate. Movies are commonly 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 Tv Sound Problems

Some uncomplicated math will show the problem and tell the solution. When a Tv set wants to display 60 frames per second, and the cable Tv business 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.

Which Size HDTV is Right for My Room?

Graphic for determining the right size HDTV for your room

With standard-definition TVs, the rule used to be that viewers would feel comfortable watching a set from a distance of 3 to 6 times the screen size in inches. With HDTV, the resolution is so much better that you can sit closer to a larger TV without noticing the pixels. So with HDTVs, the rule tends to be you can sit anywhere from 1.5 to 3 times the screen size (in inches) for the best experience.

If you know the size of the room you have already, where you want to sit, and where your new HDTV should go once you get it, you can figure out the size HDTV you should get.

  • Minimum size = Viewing distance/3
  • Maximum size=Viewing distance/1.5

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 miniature slower than the cable Tv frame rate, so if it plainly shows each frame twice and then waits for the next one, there will be a black gap in in the middle of and the movie will look terrible. So, the Tv needs to triple one frame, double 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 enough for most people to tell that it's really a static image, and when the camera pans around 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 plainly show each frame 5 times in a row for a total of 1/24 (or 5/120) second per frame, with no distinction 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 enough 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 fertilization 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 really entered the fourth dimension (time), but has skipped the third (depth) in the process. Until we see start looking holographic movies on Dvd, we'll have to wait for true four-dimensional Tv.
