There are many decisions facing consumers today is unprepared;Just trying to navigate through this maze of buildings may be a stimulating experience. But many of these frustrations can do their homework first hand is avoided.

So, where do I start?Familiar with the various concepts and classification

TV Rating:

TV analog NTSC (National Television Systems Committee), the traditional TV and is now missing on 17 February.

ATSC Digital TV – (Advanced Television Systems Committee) DTV;
These "SDTV – Standard Definition TV – the new (digital) standard for television;
replaces the analog NTSC TV.

Integrated HDTV – or, simply, HDTV, DTV, with an internal (embedded)-receiver for high-definition television.
Itare able to receive and view all the TV DVB-Seine – including HDTV-Seine.

Digital HDTV – Capable "or" Clear "Digital TV that is capable of HDTV DISPLAY – but only with the addition of an external HDTV receiver.

EDTV – Enhanced Digital TV – Digital TV * The classification describes what is essentially a high-end SDTV programs. Although this often includes some form of technical capabilities, add the product to enlarge the image, certainly not the image quality is not HDTV.Technically speaking, there is virtually no visual difference between an SDTV and EDTV – with the possible exception of the higher price.
* For many consumers, the classification of doubtful assets, paying more for a television coded as "EDTV" the consumer gets what is best described as an "updated" SDTV. The question is classified as an up-"is that if your TV only meets the standards for SDTV?

TV screens several technologies:

CRT – (cathode): Traditional TVTechnology – The standard set for the television show, best overall value – of picture quality and price; major drawback is the mass and mass as size increases. Plasma display – Ultra-thin, high contrast rating, a fixed pixel "Screen: Size up to 60 + inches, with some limitations on viewing – expensive, high risk of fires, the image quality by the inability to display black; shows hit very heavy and fragile, the image quality is lost as pixels blur and many others not Give PlasmaHDTV resolutions. The development continues.

LCD – Liquid Crystal Display: slim design, the limitations of size, display good, sharp pictures for a static display, problems with the display of moving images and the LCD screen a lot is not compatible HDTV. The development continues.

LCOS (Liquid Crystal on Silicon) – LCD technology improvement can promise for the future of HDTV screen, duration, problems of continuous manufacture, development in progress.

DLP (Digital Light Processor) – use the chip and softwareTechnology – interesting, alternative display technologies for HDTV display excellent; remove most have no other technology, affordability, and some viewers question "softer" image, and the use of "color wheel" promising future – the development continues.

TV setup screen:

Aspect Ratio
Width to height ratio of a TV or video program.

Aspect Ratio can be used for both the TV screen (hardware), or the format of the television program.

Traditional – (4:3) aspectratio of the screen is square "appearance. all analogue television broadcasts in 4:3.

New "widescreen (16:9) screen, the screen is rectangular.

Digital TV (SDTV), programs can be 4:3 or 16:9.
HDTV is always in 16:9 format.

As you can see, consumers have a number of decisions to make, long before taking their final decision to buy. Understanding the basics of HDTV demands that we become aware of a significant number of new"tech-speak 'terms.

Examples

Aspect Ratio – width, length (4:3) or (16:9) refers to the television screen, and television programs.

Image resolution – 720 p; 1080-I 480-I / P, – and was recently added, 1080, pp.

Progressive scan – display process ( "p" in 720-p)

Interlaced scanning – the process of view ( "I" in 1080-in)

D / A – A / D – analog to digital and analog to digital converter

STB – Set-top boxes (aka: Tuner, tuner, decoder or descrambler)

OTA – over-the-air or"off-the-air" – refer to local TV

These are just some of the new words they encounter.

Enigma Digital TV

As consumers begin their search for information about digital and HDTV, I soon discovered that appears as an empty "information." Trying to obtain useful, reliable information needed to purchase a digital TV may seem difficult.

Attempts to ask questions about the basic HDTV, for example: the transition from analogue DoDigital television does not mean that everyone should be forced to buy an HDTV? or, What is the difference between SDTV and HDTV, or what is needed for the reception of high definition TV in your house? Now compare the different responses you receive, or lack of knowledge about share sales people.

Note: The seller should disclose, or had information about the lack of ability to buy digital television for the consumer is loaded. This is a mandate of government.

In sharp contrast, the oppositeextreme, is the steady stream of "wrong" and "disinformation." The flood inundated the public with reliable information in general. The road to useful and reliable information is plagued with inaccuracies, errors and myths. And it was compounded by a misleading advertising and aggressive marketing tactics.

For example, here's a question asked more than once consumers about the transition from analogue to digital television:
"Can you tell me if it is true that"normal" TV will be discontinued, and all will be forced to buy an HDTV? I do not think you can do … But if this is true, when will it happen? "

Okay, it's really two questions …

The answer to the first, of course – No, not true. At least not the way the question was asked. Although it is true that "normal TV" (ie traditional analog NTSC TV), ultimately, replace the ATSC digital TV, you will have an HDTV purchase!

IMPORTANT: The FCC requiredThe transition from analogue to digital television will not refer or mean "High Definition TV!

Note: If you choose to keep the TV analog converters that connect the TV to any purchase. There are good to help with this purchase on the website listed below and are free to print.

This highlights one of the primary sources of so much public confusion about digital television and HDTV. Are two different expressions, butoften used incorrectly – if they were interchangeable words have the same meaning. Are not the same, they designate two different formats on television. |

High Definition TV is "digital", HDTV, but only one (1) in eighteen (18) Digital TV Formats "nominated in the ATSC standard.

It 'important for consumers to understand that does not mean HDTV Digital TV "is not.
Digital TV "Standard Definition TV – SDTV – is not equal toHDTV – High Definition Television.

Yes, it is up to the individual consumer to him / her, even though the foundations of Digital-HDTV.
But – attention!
Do not take anything for granted; opinions can not accept at face value.
Make sure that everything we hear or read about Digital-HDTV, comparing it with other sources.

Digital difference

Digital television signals are composed of coded instructions – (the same bits of ones and zeros "that make your computer work, and give life to 'CD'and "DVD") – that is sent to your digital receiver (aka: Tuner, Decoder or Set-Top Box "STB"), which suggests the code again.

A receiver for digital TV is not involved in the signal strength and what conditions exist between the set and the transmitter. As long as the signal is received and the code can read that digital TV can play an almost perfect picture – virtually identical to the original, back in the studio.

One of the main advantages of digitalTV is bad reception a thing of the past. One of the reasons why cable TV caught offering a clear picture of the television without incurring the viewer position. Viewers do not need to continually adjust the antenna in an attempt to "put up a weak signal from a transmitter at a distance and get a clear no. Digital TV (DTV) eliminates the" snow "and" ghosting "caused weak signals to remove or block the transmission towers. If your analog TV sets have not receivedStrong, forged ahead from the tower, you get a much clearer picture is not.

Both analog and digital television is weakened, especially as travel far from the transmission tower. On an analogue TV set, the situation has gradually deteriorated from bad to worse when the distance between the tower and increases the receiver. There will, however, the perfect digital image on a set until the signal becomes too weak for the receiver to distinguish between one (1) and a (0), after which the imagecompletely disappeared.

E 'was recommended as the effect of "rock" – the image remains stable until, suddenly, "Fall Out" on the screen. E 'possible to send Morse code compliance. As long as the person on the other hand, can make points and lines, have moved will be able to read the message. When you lose the distinction between a point and a line of their message is lost. Digital TV works the same way, instead of sending dots and dashes, it sends one million (1) and(0's) every second.

As long as the television receiver can read (1 and 0) gives a nearly perfect. The bottom line … You get a picture at 100% or nothing. What does it mean for the digital television viewer, not having to worry about how a "bad" image. Either you have a picture of what you do. But if you receive over-the-air "OTA" (OTA) broadcasts, it is necessary that the antenna must be precisely focused on the reportingsource – transmission tower of the station you see.

Adding a "T" to "DTV" = WOW! While our goal is to become familiar with the HDTV-based, so now we have primarily focused on Digital Television – DTV. What is HDTV – High Definition Television? And what is the difference between DTV and HDTV?

DTV differ from the NTSC analog TV technology used to transmit the signal. And let's look at some of the reasons why digital is better than analog. However, when you compare digital TVor SDTV (Standard Definition TV) for HDTV, the difference is like day and night! The HDTV Digital TV – MA … It 'important to understand that HDTV is digital TV? HDTV is just one of (18) ATSC formats, has been appointed consisting of digital TV. The High-Definition TV picture is displayed on the TV screen began as a HDTV signal is captured by the HDTV camera (or converted from film or another format with HDTV equipment). HDTV signaltransferred to the HDTV receiver and finally displayed on a TV screen HDTV-Capable. But it must also comply with the ATSC standard for high-definition television, to be "true" HDTV.
Note: This is more than likely that you will face problems of mis-information that digital television in different configurations, is a high definition TV. "This is not true: One can also say that until the TV to one or two criteria, or if it is reinforced by the manufacturer, the use of someproprietary technology, "Magic", which makes it – "almost" – HDTV. Again, not true!

If what you want is HDTV, make sure the TV you are considering is actually "true" high definition television. How do you know TV – HDTV? To answer this question a "small" of the fundamental technology of television will be useful.

It would be useful to understand some of the basics of HDTV to educate themselves. After all, this is a discussion about Digital-HDTV – perhaps the most important"Leap forward" in technology consumers to influence our community for over a century!

The image you see on your TV screen consists of a series of horizontal lines. Shoot 'an electron gun' bundles of energy (light), there is a layer of phosphorus to hit the inner surface of a picture tube, causing the filament. These glowing lines create the image on the TV screen. The way in which, formatted, which resolution is used, what standards are among the factors thatdetermine the type of television picture that you will receive.

TV Resolution.The image quality displayed on TV screen is essentially the result of "TV solution". In short, the TV resolution''refers to the number of horizontal lines displayed on the TV screen.

Note – Although the horizontal count (in this case) is called "vertical resolution," because the lines are counted from top to bottom – or vertically. TV resolution issometimes expressed in terms of total "pixel count, which is a product of the number of rules and the number of pixels per line

That is why the range "TV screen, standard DTV?

DTV sets are sold in two "Screen Format". Aspect Ratio refers to the ratio between the horizontal (width) measurement and the vertical (height) measurement of the screen. This ratio is also used in relation to how the image is received and displayed on the screen. The ratio of two is used in DTV (4:3) and(16:9). Units that is, (4) units wide by (3) units of height, and (16) wide by (9) units high respectively. The NTSC analog TV has an aspect ratio (4:3), the screen almost "square", because the width is only slightly above that height. For example, a (4 ') wide screen will have a height (3).

This brief introduction to digital TVHDTV-based, provides an overview (intentionally simplified) as DTV is different from traditional analog TV, and how different from HDTV, SDTV digital, and soon the transition from analogue to digital television.
