HD (high definition) is one of the buzzwords of the modern TV industry. Chances are that you have heard the word, even if you don’t truly understand how the technology works. If you don’t understand how HD TV works, don’t feel alone; there are plenty of people who have no idea what’s behind the technology, why HD offers a better picture, or even what they need to access this innovative technology. Here, you’ll find a brief guide to helping you understand why HD is the best option for your needs and what you need to access it.
How Does It Work?
The difference between HD TV and SD (standard definition) TV begins long before the picture reaches your receiver. In order to record TV programming in HD format, it must first be filmed on special cameras. Of course, programs that were not filmed in HD can be converted (and many are) through a special production process that enhances the images. Of course, these are never quite as clear as programs filmed in HD to begin with.
The recording process ensures that there are more lines per image, meaning that there are more pixels used to create the image. This results in an image with much better resolution, rivaling what you can see with your own eye. Once the program has been recorded, it is sent out through the airwaves, just the same as any other satellite TV signal.
What Do You Need?
In order to gain access to HD programming, you will need several things. First, you will need an HD TV. These have come down considerably in price, with plasma currently being the cheapest technology. Other options on the market include LCD and DLP, as well as a limited selection of rear-projection HD TVs, though these are rapidly falling out of favor.
Choosing the right TV is very important. You’ll find that not all HD TVs are created equal. For instance, a TV with a resolution of 720p is not the equal of one with a resolution of 1080p. The number represents how many lines of resolution the TV offers (i.e. the higher the number, the better the resolution). DirecTV currently supports all HD TV resolution types, from 480i all the way up to 1080i.
Once you have chosen the TV that’s right for your needs (including size, price and resolution), you will need to sign up with the right satellite provider. Cable companies are not a good choice for HD TV, as they only provide about 80 channels. As a note, Dish Network provides about 100, while DirecTV provides more than 130 HD channels. When choosing an HD TV provider, make sure that you compare the costs of the different packages available; this will help you get the channel lineup that you want, and a price that you can afford. HD programming has dropped radically in price, allowing the average consumer to easily afford this tremendous technology and enhance their viewing pleasure.
