There’s a lot of talk these days about frame rates in the new HDTVs. The frame rate is simply the number of distinct 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 moving pictures look smoother. But, the human eye can only process about 20 to 25 distinct 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 answer 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.
Some simple math will show the problem and reveal 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 little 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 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 simply show each frame 5 times in a row for a total of 1/24 (or 5/120) second per frame, with no variation 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 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 certainly 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.

Getting the lowest iPod prices is a priority when you are low on cash, but still want to keep up with the latest trends and upgrades that Apple has to offer. Before you start shopping around for the lowest prices out there, it’s best to know exactly what you want, and what you will get for your money. To do that, let’s conduct our own apple iPod review and first look at the different kinds of iPods, what they do, and what you will pay for those particular services and perks.
Let’s start with the high-end iPod: The iPod Touch, and quite obviously not a really cheap iPod. This is the cream of the crop when it comes to iPod technology. With a touch screen and all kinds of interesting additions, including Wi-Fi, the iPod Touch has a good reason to be the most expensive of the line. At the time of the writing of this article, it’s priced by the Apple store at 229 dollars for the low end, and 399 dollars for the one with all the bells and whistles.
The next on the list is the iPod Classic. Again, these are not very cheap iPods. This is the big daddy of them all when it comes to music, capable of holding over 30,000 songs on the hard drive. That’s more than some radio stations have in their computers! The iPod Classic can run movies as well. The cost of the Classic is about 249 dollars.
Next on the scale of price is the iPod Nano. The new generation of the iPod mini, the Nano can play 24 hours worth of music, and can hold quite a bit in the library. It plays movies as well, but not as well as the more expensive models do. The low end on the Nano is 149 dollars, and the high end is 199 dollars.
The iPod Shuffle is the smallest of the bunch, with the lowest level capability and lowest iPod prices, but it’s still a great device. The Shuffle is for those who are all about the music. The very compact size – smaller than a lipstick case and shorter than any cell phone – means it can go anywhere at all. The cost of the Shuffle is anywhere between fifty dollars and 80 dollars.
Which one is the best for you? It depends on what you want. Once you have decided what you need, you can go on from there in determining where to find the lowest prices for that particular model. A quick look at online auction houses and some online merchandisers will give you a good idea of how cheap a refurbished model can be…sometimes you can get them for as little as 20% of the original price!
So, what do you want? Movies? Games? Music? A little bit of music, or your whole library on one convenient little iPod? The choice is entirely up to you. When searching for the lowest ipod prices, whether you want to spend thirty dollars or are willing to drop five hundred, you are sure to find the iPod that suits your lifestyle – and your budget.

Although the price on an HD flat tv has gone down quite a bit over the past year, it’s still not something that you just go out and buy without at least knowing a little of what you’re doing. There are a ton of new technologies in these tv’s, plasma, lcd, high-definition, and knowing what you want and why you want it, will help you save money and be happier with your purchase.
So, what should you be thinking about when you go shopping for an HD flat tv? Well, here are a few points that I think are important.
The first thing you need to consider is what brand you want to buy. Currently the big makers are Sony, Panasonic, Samsung, and Toshiba. You don’t have to go with the absolute industry leader, but choosing a company that’s solidly behind your purchase is wise. Right now, just judging from what I see in the marketplace, I would guess Samsung is the industry leader. At least right now, Samsung seems to have more choice available for consumers.
The next thing I would do would be to decide what you’re going to use your HD flat tv for. Are you just going to watch cable TV or DVD movies, or will you play video games on it. How about hooking it up to your computer? Knowing what you’re going to use it for will make a difference in what you buy.
Next, I would consider what resolution TV I want to buy. Are you going to buy a very high resolution 1080p TV, or would something of a lower resolution suffice. What does it matter? Well, it all gets back to what you’re doing with the TV and how much you’re willing to spend. Also, some of the lower resolutions are so low that they don’t qualify for being HD, or high-definition. The resolutions available are 480, 720, and 1080. These numbers refer to the number of lines that are scanned on the TV when it creates the picture. 720 and 1080 qualify for high-definition, while 480 is only standard definition (like your old TV!).
Finally, you need to decide if you want an LCD or Plasma TV. They both have their strengths and weaknesses. LCD tv’s are lighter, so they can be easily hung on a wall. Their screens reflect very little light, so they work well in well-lit rooms. Disadvantages are they can have a problem with ghosting. Plasma TV’s, on the other hand, have faster response time and higher brightness and contrast levels. Disadvantages are they need extra support if you want to hang them on the wall.

If you’re in the market to buy an HD TV, then I’m sure you’ve found out there’s a lot more to know about buying TV’s now than there used to be. Ten years ago, all you would do was to walk in the store, take a look at the screens, then buy the one that looked best to you. You didn’t have to worry about compatibility with various video game systems, Blu-Ray, even computers.
Well, things have changed. Now, you need to get a little education before you buy an HD TV. Let’s look at what you need to know.
Basically, you need to understand who makes the TV’s and who are the best companies to buy from. You need to understand resolution, especially what is defined as high-definition. Understanding the difference between plasma and LCD technology is important. Finally, really getting a handle on what you’re going to use the TV for will help you choose the right one.
Let’s go over each of these in turn.
Manufacturers
There are several big manufacturers of HD TV’s, but the main four currently are Sony, Samsung, Toshiba, and Panasonic. I would love to be able to tell you that one is a lot better than the other three, but that’s not the case. Samsung seems to have more choice, but the other three manufacturers have plenty to choose from, too!
Resolution
Right now, TV’s come in three resolutions, 480, 720, and 1080. Now, there’s a little more to clarity than just the resolution, like how the TV actually creates the picture, but you need to at least understand these three numbers and what they mean.
The numbers refer to the number of lines the HD TV scans across the screen in one pass. The higher the number, the greater the resolution. Only 720 and 1080 are considered “high-definition”. 480 will look good on a smaller set, but you won’t get that Hi-Def effect!
LCD vs. Plasma
Again, between these two, there’s no real winner. LCD TV’s are lighter, and thus easier to mount on the wall. Their screens also reflect less light than plasma screens. Also, they use less power.
On the other hand, some people think plasma pictures have deeper colors–they look more cinematographic! Part of the problem with plasma TV’s is that they are heavy. They’re harder to mount on the wall. Larger TV’s will require extra bracing, if you want to mount them. Also, you can have burn-in on the screen more easily.
Uses
Finally, when you’re deciding which HD TV to buy, you need to really think about what you want it for. Are you using it just to look at cable and DVD’s, or do you want to play video games on it?

The most notable feature of the iPod Shuffle is its physical dimensions. It’s the
same size as a pack of gum. It’s basically a memory stick.
It supports:
1. MP3 audio encoded at up to 320Kbps.
2. AAC audio encoded at up to 320Kbps.
3. Protected AAC audio from the iTunes music store.
4. Audible music format and WAV files.
5. Mac OSX v10.2.8 or Mac OSX 10.3.4
6. Microsoft Windows 2000 with SP4.
7. Windows XP Home or Professional with SP2 installed.
The ear buds that come with it are of relatively high quality. If you plan on using
it while working out you will like the long cord and the optional armband. You can also
wear it like a necklace if you wish to.
One feature I like about this MP3 player is it supports USB 2.0, so music transfer is
very quick and easy. There are only two playback modes to choose from, random play
(thus the name Shuffle) and repeat all, which will play your play list in order and
repeat the entire collection after the last track has finished playback.
The Verdict
Apple’s iPod Shuffle is meant for anyone who wants to simply play music. I personally
purchased mine to complement my hard drive audio based player. If you are a sports enthusiast
like I am then the iPod Shuffle will be a good choice when working out since the larger iPods
are not suitable in such environments.
The design of the iPod Shuffle and the way it sounds is fantastic and iTunes software works
great with it and it’s good at what it does (to play music). it’s a good buy and will highly recommend it.
Pros:
1. Affordable compared to other MP3 players in the same range.
2. Portable, small and light weight.
3. Very easy to use.
4. Great sound quality.
Cons:
1. No LCD display.
2. No equalizer settings.
3. No voice recording.
4. No integrated FM tuner.
5. Inability to pick and choose songs or albums to play.
6. Only support Apple iTunes software.
7. Battery is not removable.

One of the most frequent questions asked when buying a new HDTV set is: how to compare lcd and plamsa tvs? If you have been considering buying a flat panel screen television for any of the reasons that everyone wants them; like save space and for the beauty and technology advantage they offer, then you must have been very confused upon reaching the store to find that you really don’t know the difference between one from the other.
LCD rear projection television should not be confused with LCD flat panel televisions. Rear projection LCD uses a powerful light source through a transparent LCD chip made up of individual pixels (which displays the moving video image) and projecting that image through a magnifying lens, to a mirror, which then reflects that image, onto a screen. Because the chip is so small the panel of a rear projection television can be made very thin and light unlike in televisions that use the CRT (cathode ray tube) technology.
Although they are still far from being hanged up on the wall like plasma or LCD flat panel televisions they can save quite a lot of floor space. They are also cheaper than plasma and LCD flat panel and come with wider screens. LCD rear projection technology is also brighter and offers more contrast. LCD screens are less likely to suffer burn in so they can be used as computer monitors at the same time unlike plasma screens that are likely to burn in fast because a computer would be on for longer.
Plasma television is almost always a flat panel; this is because it uses technology that allows it to be housed in a smaller panel. Similar to the technology of the fluorescent lamp, the display of a plasma unit contains xenon gas between two glass panels. The gas is injected in the form of plasma; when the gas is charged electrically it lights up red, blue and green phosphors and so an image is created. Red, blue and green phosphors make up a pixel.
Meanwhile traditional CRT models use a large vacuum tube, where and electric beam scans the surface of the tube to light up the phosphors and is the reason they have to be housed in larger units.
Plasma televisions are considered to provide better quality picture than LCDs especially in the larger sizes. They display high definition content and colors better than LCD but LCDs perform better in smaller sizes especially for computer screens and small televisions sets for the kitchen and bedroom. However, most people consider bigger plasma screen of 40 inches and more for the living room for movies.
Plasma televisions offer a better price to size ratio than LCDs but LCDs are offers more models in the smaller sizes than plasma which has mostly larger screens. Smaller LCDs screen are better for computer and games usage and for sets in the bedroom and kitchen.

The 40″ Sony Bravia KDL-40V2500 is an awesome LCD HDTV displaying 16:9 1080p at 1920×1080 resolution. Sony has hit the mark with the Bravia KDL-40V2500 especially with the lowered price to compete with other LCD HDTV companies like Samsung, Sharp, Panasonic, and Toshiba. The quality is top notch. The colors and contrast are near perfect and pictures even appear to jump out of this LCD HDTV more than other LCD TV’s when compared side by side.
Watching non HD content is not a problem with the Sony Bravia KDL-40V2500. Even playing regular DVD’s look almost HD with an upscaling or upconverting dvd player like the OPPO DV-980H or Sony’s own DVP-NS77H. I heard you can use the remote from Sony’s dvd player to operate the V2500 series. SD (or standard display) is also good and better than other LCD TV’s and almost to the level of your old CRT tube tv set.
The remote control is not bad, but there have been some dissatisfaction with it from some owners saying that it feals cheap or clunky. You’ll probably end up getting a universal remote anyway if you don’t like the factory TV remote. Any negative thoughts caused by the remote are easily made up for with the excellent and simple menu. Going through the Bravia 40V2500’s settings is a breeze. One great feature of this LCD HDTV that you should enjoy is the ability to label the inputs and skip the unused inputs. This should be included with every TV set.
There have been some reports on fogginess in dark scenes, but not many owners have seen it. Maybe messing around with the display or lowering the brightness will help if you see this in your own TV set. Also, if you see a white line above the screen, just raise the vertical display a little bit to make it disappear. You can also change the display area from “full pixel” to normal and that will get rid of the white line.
The Sony Bravia KDL-40V2500 LCD HDTV comes with two hdmi inputs. If you’re buying hdmi cables, you don’t need to get the expensive ones. You can buy hdmi cables for under $15-$20 and they work just as good as the ones that cost an arm and a leg. If you plan to buy the warranty for the Sony Bravia KDL-40V2500 LCD HDTV, you can get it cheaper straight from Sony instead of from Amazon.
Overall, the 40″ Sony Bravia KDL-40V2500 LCD HDTV is an awesome television with stunning visuals that will drop jaws like when people went from b&w to color TV’s. The refresh rate is not extremely fast as is expected from an LCD TV, but it shouldn’t be a big impact on the viewing experience. The sound is as good as any LCD HDTV on the market if not better. I didn’t cover the sound much, but it is definitely not weak and may surprise you with how good it sounds. Sony has put together a complete package in the Bravia KDL-40V2500 with great visuals and audio to deliver an immersive experience to the viewer. This LCD HDTV may be the best bang you can get for your buck.
