There's a lot of talk these days about frame rates in the new Hdtvs. The frame rate is simply the estimate 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 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 lively 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 respond comes when you realize that not all video is filmed at the same rate. Movies are ordinarily 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.
Some straightforward math will show the problem and enumerate 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.
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 puny 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, 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 population to tell that it's actually 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 simply show each frame 5 times in a row for a total of 1/24 (or 5/120) second per frame, with no dissimilarity 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 gravidity of reality. The 120Hz frame rate won't be very coarse 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 size (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.

This product is 3D-related. To help you get a great 3D experience, use the checklist below to ensure you have everything you need. 3D viewing requires:
 | A Display First, you'll need a 3D-ready display--whether it's a 3D HDTV, 3D projector, or 3D computer monitor. These displays have more processing power than standard 2D models for displaying 3D images in rapid succession. |
 | A Source Your display may be ready for 3D playback, but you'll still need a device to read 3D content. This can be a cable box with a subscription to a 3D channel, a 3D Blu-ray Disc player, or a PlayStation 3 system. |
 | 3D Content 3D content--the actual entertainment, in other words--will be played back using the source mentioned above, whether it's a 3D broadcast from your cable provider, a 3D Blu-ray Disc, or a 3D video game. |
 | 3D Glasses For now, the vast majority of 3D HDTVs require glasses for 3D viewing. Many use powered "active shutter" glasses, others polarized "passive" glasses. You'll need one pair per viewer, and they'll have to be compatible with your display, whether they're the same brand, or a pair of "universal" glasses designed to work across brands. |
 | HDMI Cable To connect your source (such as a 3D Blu-ray Disc player) to your display, you'll need a high-speed HDMI cable. Cables with this designation feature bandwidth speeds up to 10.2 Gbps (gigabits per second), for carrying the 3D signal without any loss of quality. |
