Video Cards and Related Technologies

How does a video card work?

A video card basically converts the computer’s digital signals coming from the processor into a signal that the monitor is able to interpret. Hence, its basic function is to convert data. The main point of difference between an entry level video card and a state-of-the art one is that the latter’s conversion speed is much better.

The Chips

The chip is the heart of the video card. It is where all the processing is done. It also makes 3D acceleration possible. The chip is to the video card, what the processor is to the computer. Of the two major chip manufacturers, ATI and NVIDIA, the former is well known for high quality and great technology.

Pipes

The information must travel through tunnels called ‘pipes’, before it can be converted. On one end it starts as raw data and ends up at the opposite end in a format that is compatible with the monitor. On its way, the data undergoes the conversion process. The greater the number of pipes, the more data that can be converted simultaneously.

The amount of data that a pipe can hold is called its Memory Interface. A pipe with a 128 bit interface can process more data than one with a 64 bit interface.

Memory

The memory is used to store temporary or transient information. Video information, being very data heavy, needs more memory. The two main types of memory are SDRAM and DDR RAM. DDR is superior as it can transmit information faster.

ATI Technology

An ATI card will offer many technologies that will significantly enhance your video experience. ATI’s cards are fully compatible with all the latest 3D technologies and do not rely on your computer’s CPU to process information, as do some of the entry-level cards.

SmartShader™

This technology will unleash a new generation of visual effects on your computer. Realistic graphics with breathtaking 3D effects are possible with SmartShader™. DVD movies can be viewed to better effect with it too.

Sales Projections Assume That Both HDTV DVD Technologies Will Survive Format War

Ever since the Blu-ray HDTV DVD format barged into the market right on the heels of Toshiba's introduction of the HD-DVD format the prevailing wisdom in the home entertainment electronics industry has been that only one of these two formats would be able to survive the inevitable format war between them. The inescapable logic of the fact that in order for only one to survive, the other has to perish has led many consumers to put off the purchase of any high def DVD technology at all because of the aversion to being left with obsolete and therefore useless technology.

The possibility of being left with the embarrassment and lost money of having purchased a losing technology is not without precedent. In fact, one of the reasons why consumers have been so reluctant to purchase either an HD-DVD player or a Blu-ray player is because many of them still have memories of the war between the VHS and Betamax video cassette formats back in the early nineteen eighties. Eight track tapes provide another cautionary tale.

There is one fundamental difference between the current high def DVD format war and the video cassette and audio cassette format wars: Betamax was a different size and shape than VHS and eight track tapes were shaped differently from the winning audio cassette format, while the diameter and thickness of Blu-ray discs and HD-DVD's are identical. This means that while those warring magnetic tape formats weren't physically capable of being played on the same cassette deck, there's absolutely now reason why you can't at least load Blu-ray discs and HD-DVD's into the same drive.

The fact that Blu-ray discs and HD-DVD's have identical dimensions (and dimensions that are identical to CD's and conventional DVD's as well) has prompted some companies to find ways to work around their incompatibilities. For example, Warner Brothers has come up with a way to print a movie in Blu-ray format on one side of a disc and the same movie in HD-DVD format on the other side of the same disc. If this format becomes mainstream, consumers will be able to buy high def DVD's regardless of which type of player they have and without paying any attention to which format they're buying.

LG and Samsung have also come up with a way to work around the incompatibilities by producing a device that can read discs in both formats. These dual disc format high def DVD players cost a little bit more than normal high def DVD players, but take care of all of the compatibility concerns.

These technological developments have prompted the industry to rethink the wisdom that only one format can survive. Rather than assuming that one format will go extinct, many sales projections take into account the possibility that both will be around for a long time. If this is the case it will be because these other technologies that bridge the gap between the two formats have thrived and been embraced by consumers. And as far as Toshiba and Sony go, while neither will dominate the high def DVD market the way they both hoped they would, they should take some solace that neither will end up losing completely either.

Some HDTV Technologies Are Better Than Others at Displaying SDTV

Despite the growing popularity of HDTV and the rising sales of HDTV sets, most of the TV content that's watched on HDTV sets is in standard definition television- the older format that's been around since the dawn of broadcast TV more than half a century ago. There are two major reasons for this. The most obvious reason is that there are still far more standard def channels than there are HDTV channels. In other words, not everything that every HDTV owner wants to watch has made the transition to HD.

The second reason why most of the TV programming that's watched on HDTV sets is still standard def is because HDTV programming isn't nearly as popular as HDTV sets. The evidence for this includes the fact that there are only about half as many households with subscriptions to HDTV programming packages as there are households with HDTV sets. There are several reasons for this. For one thing, HDTV has become something of a status symbol and the HDTV sets are much more evident of this status than having the HDTV programming to watch on them is. Another reason is that HDTV sets have the wide screen aspect ratio that many DVD's and an increasingly large number of standard definition TV shows are available in. The wider viewing area is a good way to heighten enjoyment of watching TV, and in many ways is more noticeable than the high resolution picture that you get with HDTV. Yet another reason is that modern video game systems like the Xbox 360 and Sony's Play Station 3 can display their graphics in high def resolutions and take advantage of the 16:9 aspect ratio of HDTV sets.

Despite all of this, many people find standard definition programming relatively unsatisfying on HDTV sets. There are several reasons for this. For one thing, the analog format that a lot of standard definition TV still comes in, isn't completely compatible with a lot of HDTV sets. This causes a worse picture in many ways than if the same programming was just displayed on a standard def screen. Another problem comes from the fact that HDTV screens are simply designed to display more pixels which result in a more detailed picture than you can get from a standard definition TV set or standard def programming. Therefore, the result of displaying standard def programming on such a high def screen is missing pixels which cause the picture to look grainy and generally low quality. This is especially obvious when standard def programming is displayed on a relatively large high def screen.

There is a way to combat this problem though- buy an HDTV set that's good at rendering standard def programming. There are a variety of sets that are better than average at doing this and they're made in a variety of technologies. DLP projection TV's and Plasma screen TV's can both be good at this, but there are more LCD screen HDTV sets on the market that are well rated for displaying standard def programming than any other type on the market. One thing that will help is getting an HDTV set with a built in up converter that will fill in the absent pixels to make the SD picture look sharper. Barring that, a smaller screen will look better because the gaps in the picture will be harder to see.

In all, this is a problem, but not one that can't be avoided with a little bit of foresight.

Christmas Electronics - Get Great Deals on the Hottest Technologies

When you buy electronics for Christmas, you can often get outstanding deals on new products. Read this article to find out the proper strategies to use when buying gadgets and gizmos at Christmas and throughout the entire year.

Let's first ask this question: What is the primary difference between a digital camera made today versus one that was made 6 months ago?

If you answered "the price", you are probably right.

In my job, I am constantly doing product comparisons. There are two main categories that I look when doing these comparisons: features and price.

We need to ask the question, "What, if any, new features does this product have? What sets it apart from its predecessors?" For example, if the product is one of the new point and shoot digital cameras, we look at things like usability, megapixels, style, and, most importantly, user feedback.

The second category is price. How is this new technology priced in relation to other cameras that have these features? And, perhaps more importantly, how does the price of this item compare to the previous model?

When we ask these questions, we often find that there is a price to the "newness" of an item. It is always fun to say that you have the latest and greatest gadget. We all know these people who are waiting at the store to get the hottest new item. We know because they tell us all about it and show off their new techie toys to us.

But are they getting a good deal?

The answer is "absolutely not", with one exception.

The features that are added to a "new" item are usually those that you will never use or features that do not justify the exorbitant price of the item. For example, if we take a look at the top rated LCD TVs, we can see a huge price difference between those that are 50 inches and those that are 52 inches. How much extra are you willing to pay for those extra 2 inches? In many cases, the price for those 2 inches is about 100% more.

The general rule is this: If you buy the latest gadgets, you are paying more for the "newness" than for the features. However, there is one exception to this rule.

Christmas. Over Christmas, manufactures often lower their price on the latest items because they make up for it in volume. Thus, during the Holiday season, you are able to buy the latest items at very competitive prices.
