Simply put, high definition television is the biggest breakthrough in broadcasting since color TV back in television’s early days. It offers viewers wider pictures in greater detail with the clarity of something you would pay to see in a movie theater. A true HDTV image has twice the luminance definition, both vertically and horizontally, and is twenty-five percent wider.
High-Definition is the top of the line when it comes to watching TV because of its all digital format. With HD, your TV screen displays images at a higher resolution than your older television never possibly could have through pictures delivered in a crystal clear, widescreen format, along with CD quality sound.
It will change the way you watch movies and your favorite shows. Here are a few of the most common questions asked about high definition televisions with the answers to help you when it comes time for you to make that big purchasing decision.
What do resolution line numbers mean?
All television programs compatible for high definition encoded with one of three types of resolution, 720p, 1080i or 1080p. These numbers represent the quantity of lines embedded within the signal. You’ll notice the letter that corresponds with the number and that represents the type of scan used to display the picture. “I” stands for interlaced and ‘p’ means progressive.
Does the number of lines matter?
This one is simple. The amount of lines a television has gives it more detail in the image onscreen. Think about how dpi is used to print quality of a digital photograph. Older TV sets only had 480 lines. TV’s today have doubled that and that is the reason why the pictures are so much clearer. The type of televisions our parents had used 480 visible lines on the screen.
Is interlaced or progressive resolution better?
The number of lines is more important that the type of scan but that doesn’t lessen its value. Progressive scan is more popular because it doubles the amount of times the TV displays the image per one second but the difference between 720p and 1080i is so small that it isn’t worth racking your brain about. The 1080p is better than 720p and 1080i, but since so few programs are made in this resolution; it isn’t and shouldn’t be a factor.
Is my television HD compatible?
This is where you may run into an issue since only high definition televisions can display HD content in the HD resolution. There is a few which can display HD content in a 480p resolution DVD quality. Analog TV’s can not display HD content in a HD resolution because they lack the technology to do so.
Am I watching high definition automatically with an HDTV?
The answer to this question is not exactly or a better answer is not yet. Just because you own an HDTV doesn’t mean you will watch everything in high definition. This is only the first step of three. The next is to buy an HD tuner. These are usually built into the television or bought as an external set-top box. Now that you are good to go with an HDTV and an HD tuner you need to subscribe to a HD package. Only after all three of these steps are completed will you be able to receive the signal on the HD channe
