How HDTV Is Taking Over The Entertainment Industry

By Kim Pascel

You've probably heard about it, and you're probably wondering about how it all works. It's advertised everywhere, and everyone is trying to get you to buy one. With Blu-Ray out now, it's even more critically acclaimed. Here are some things that should help inform you about HDTV technology.

Firs off, what does HD even mean anyway? It means high-definition, but that doesn't describe much either, because high-definition just means better quality, and that's pretty vague. The first TV to be considered HD was back in 1934, and it was considered high-definition because it boasted a 30 pixel resolution. While that's a joke now, it was a big deal back then. Nowadays, the common high-definition TV has a pixel resolution of 800,00 or more.

That's not the only reason why it's a bigger deal now, though. Another reason is advancing technology of output video. That is to say, the invention of things like Blu-Ray. Blu-Ray is an HD medium that makes HD technology not only more supreme, but necessary in order to take advantage of the higher quality. Blu-Ray quality is outstanding, for sure, but you can only use it if you have an HDMi port on your TV.

This is what the point of HD really is, however. Being able to utilize higher quality is more than just having a higher quality TV, but also a higher quality broadcast, be it by DVD or cable TV. That is what makes HD so much more advance in the modern world, because of things like Blu-ray and HD channels. They have their own compressed pixel ratio that you can't even see with a regular TV, making HD seem so much more exclusive as well as effective.

Because HD has become so much more important, it now comes in a completely different form. That's why you need to have HDMi connectors to even use the real HD aspect. An HDMi connector is a high-definition multimedia interface, and is capable of reading and translating the digital information from an HD source to put it on your screen. Only certain things can use the HDMi port, and are the only things that can utilize the full potential of HD.

The aspect of quality is in question based on the medium to which you are watching HD. That is to say the difference between 1080p and 1080i. Most TVs have 1,080 lines of resolution, meaning that the image you are viewing is broken up into 1,080 lines. More lines, like with pixels, means higher quality, so 1080 is a pretty decent resolution.

As for the "p" or "i" part, that refers to the form of image scanning. These 1,080 lines if resolution need to be constantly scanned to refresh the image. If it's 1080i, then the image is "interlaced", meaning that the even and odd lines alternate to conserve bandwidth. The sacrifice of a reduced bandwidth is a "twittering" effect of the image. If it's 1080p, then the image is "progressively scanned" or sequenced. The lines follow each other as they're being written, sucking up more bandwidth, but producing an overall higher quality video.

There's no question that an HDTV is a better quality machine, but it's only better depending on how you use it. The technology of the TV is only as strong as it's weakest link. Not having the TV, for instance, is the same as having the TV and not having the connection. Overall, though, it's home theater brought to a new, and better, age.

The Major Benefits Of HDTV

By Mike Gilmore

Most TV viewers are realizing the inadequacies of cable service with bad picture quality as well as absence of programming options. As a result, they are turning to other options that have more to provide and even cable TV providers that are able to supply high definition programming are only able to do so in exceedingly limited portions. This is because cable providers generally do not have the technology necessary to deliver the HD TV (HDTV) programming in the higher quantities and variety that satellite television suppliers are able to supply. Both Direct TV and Dish Network provide a variety of high definition programming that is quite appealing to TV fans.

Being able to offer more than 30 channels of HD scheduling the Dish Network has become very popular with television viewers. A large number of channels, which is higher than the cable service company or even any other supplier, are provided in the DirecTV HD package. More numbers of high definition scheduling could be added by the viewer to the already present program packages, provided by the satellite service providers. This works our very economical for the viewer who can add any number of high definitions scheduling to the basic package. A large number of viewing options as well as numerous music channels are included in the standard package.

The added benefit of a high definition audio technology is part of the HDTV scheduling which both the satellite suppliers provide. The digitalized surround sound is music to the ears since it uses the Dolby noise reduction facility and seems as if it is from a CD where every note is clear and sharp. Viewers therefore find the quality of sound coming from their HD scheduling much better than the sound they are familiar with from their TV. To add more zing to their audio experience a lot of viewers hook up their TV to stereophonic loudspeakers.

Additionally viewers can access a far superior picture quality when they take subscription packages from Dish Network or Direct TV HD. Though everyone talks about the superiority of HDTV, most viewers can not realize that the full benefits can only be appreciated with high definition programming. The unique technology of HDTV allows viewers to see a picture that is far more defined and precise with HD scheduling. Satellite TV is able to provide more channel options then cable since they have not even hit the capacity of their current hardware.

The fact that costs of HD televisions have been slashed down has made it feasible for more customers to enjoy viewing high definition TV. So much so that customers are finding that buying a HDTV is far more affordable and not very much more than a standard TV set. With the growth in the number of HD scheduling from satellite suppliers, we can always find that soon there would be more people who are also enjoying this type of facilities.

Differences Between LCD And Plasma TVs

By Jason Thomas

There are many televisions on the market today, with several different types of displays. However, the two types of television most often discussed are the LCD (or Liquid Crystal Display) television and the Plasma TV. Each of these two types has its own unique advantages and drawbacks.

Lets start with the LCD television. This television utilizes individual lights to create the image on your screen. These televisions have a relatively long life span, at an average of fifteen years of use. An LCD television is also lighter than the televisions that you have grown accustomed to, and it is even lighter than many of the Plasma Televisions that are available for purchase. An LCD has high levels of brightness, however the contrast and black levels is where the LCD television starts on the downward slope.

As mentioned before, the LCD uses individual lights to create the images, therefore it must block out these lights to create black. Also on the negative side of LCD televisions is the pixels. When the viewer is watching a fast paces show, such as a sporting event or an action film the image will often be unclear and look pixelated.

Plasma televisions, which use individual pixels to create the images, are known for having one of the best brightness and contrast rates and for having some of the truest achievable blacks. They are only available in sizes of 37 inches and above, however, generally speaking the Plasma TV is usually the more affordable choice in the 42 inch and up category. Plasmas have no "sweet spot" - they are viewable from nearly any angle with little or no loss of picture quality. Like the LCD, the Plasma TV is relatively lightweight.

Although plasmas are a truly great television to purchase, there is one major drawback and that is the stamp effect of the images on the screen. The stamp effect refers to the "burning" if images on the screen after it has been on the television for a length of time. Therefore, if you leave your television on a channel that keep the logo on the screen all day you may find that your televison has a "ghost" image of the logo even after you switch to a new channel.

What is the Best Television for Your Home Theater System?

Can the Vizio SV470XVT1A be the perfect television for your home theater system?
You have a wide variety of choices when it comes to choosing the best television for your home theater system, but the most important variables are size and picture resolution.

It is common to choose a television 27 inches or larger as the focal point of your system. A common misconception is the larger the screen, the more cinema like the home experience. This can be true in some cases, but there are many things you should take into consideration before buying a television.

The size of the room in which you are planning to place your home theater system can help determine what size screen you should get. As a general rule, the larger the set, the more room you need to allow to create the proper viewing distance between you and the television. It would also be wise to consider the amount of natural light that the room you have chosen receives. Some larger sets do not perform well in a bright environment. Also, make sure you have measured the area where you plan to place the television, in order to choose a set of the proper size.

When deciding on a television for your home theater system, you can choose what is known in the industry as a direct-view TV, the kind most of us are familiar with, and the least expensive. Other options include a rear-projection TV, which includes the LCD display, the flat panel TV with either an LCD or plasma display,(e.g.Vizio SV470XVT1A)
or the rear projection TV, which requires a separate movie screen.

Choose a television which receives a digital signal, instead of analog. Digital signals are progressively scanned, which provides a higher picture resolution. Such a set will be simple to locate as the United States is changing its broadcasting format from analog to digital, and televisions are being manufactured with this in mind. The highest quality digital signal is known as HDTV. You must purchase a compatible set in order to get this extra resolution, but these are the most expensive televisions. You can invest in an HDTV-ready television for your home theater system, and upgrade later

To insure you will be well satisfied with your home theater system, take the time to compare several different brands of the kind and size of television you are most interested in. Make an educated decision based on planning and research for years of enjoyment.

Vizio has become over the years a dominant force in the Budget Flat panel/LCD arena. The company is now looking to enter into the profitable field of high-end HDTVs. With its XVT line which is comprised of a 50-inch plasma and a pair of LCDs, including the model we talk about here, the 47-inch SV470XVT1A. This LCD is set up in a nice glossy black finish, there is a more polished menu system, a newly improved remote, and the 120Hz dejudder processing. This is standard on many high-end models from other manufactures including Sony, LG, Samsung and Mitsubishi. On paper Vizio is showing a big effort to compete with the established big boys of the industry. Vizio actually succeeds in many ways, beginning with the superior color and generally excellent video processing, however there is some unsteadiness with the dejudder.

While the SV470XVT1A may not be able to match the black levels of many of its competing displays, it is priced very aggressively. This is least expensive of all the 120Hz equipped HDTV on the market today. This enhances its appeal for folks seeking that high quality within their budgets.

Equipped with a lot of glossy black, a slicker menu system, a redesigned remote, and the 120Hz dejudder processing also found on high-end models from Samsung, Sony, LG, and Mitsubishi, this Vizio makes a strong bid on paper to compete with the big boys.

This HDTV LCD makes the ideal gift at this time of the year.
