Is your TV ready for the transition from analog to DTV, February 17, 2009?
This date is much closer than you think.
A better understanding of the transition to digital television, HDTV, and knowledge of these principles will helpwilling to consider if there is time, a new TV.
Buy a new TV today can be overwhelming and includes more than just a visitor to your local television or electronics store. Shopping for a digital television or HDTV as possible with all the acronyms, names, the resolution of confusion, dpi, sizes and options that you can get on TV today.

So what Consumer's Need to Know
There are so many choicestry to deal with consumers only unprepared to navigate through this maze complex world of today can be a daunting task. However, many of these frustrations can, while doing some work before hand to avoid.
Things to Know Before You Go
What is digital TV … and is not. What is the digital TV transition … and how it affects you. As HDTV is different from all TV formats … and instructions. You know what they want and need so that they are sold something you want or need!
So where to start? Familiar with the different conditions and classification
TV Rating:
Analog TV NTSC – (National Television Systems Committee), traditional television, now expire in February 17.
ATSC Digital TV – (Advanced Television Systems Committee) DTV;
This is "SDTV – Standard Definition TV – the new (digital) standard for television;
replace analog NTSC> TV.
Integrated HDTV – or, simply, HDTV, DTV constructed with an inner (receiver), High-Definition TV.
This is able to receive and display all ATSC TV signals – even HDTV signals.
Digital HDTV – "Capable" or "TV Digital Ready 'is capable of HDTV DISPLAY – but only with the addition of an external HDTV receiver.
EDTV – Enhanced Digital TV – a classification that describes * Digital TV 's, which are fundamentally'high-end' SDTV's. While this is often a kind of technical characteristics, the manufacturer has the image, but specifies that the image quality does not improve immediately HDTV. Technically, there is virtually no difference between an SDTV and HDTV – with the possible exception of the higher price.
* For many consumers, this classification is of questionable value, has more money for a television "HDTV", the consumer is to get only what is best described as a"upgraded" SDTV. The question is, how up-graded "is when the TV just met the standard for SDTV?
Several TV Display Technologies:
CRT – (cathode ray tube): Traditional TV Technology – the established standard for TV shows, the best overall value – the image quality and cost, big disadvantage is, the volume and mass is greater. Plasma Display – Ultra-Slim Design, High Contrast votes, display 'Fixed pixel': sizes up to 60 + inches, some displayRestrictions – expensive, high risk of burn-in image quality through the inability to display black, displays are extremely heavy and fragile, lost image quality than fade pixels, plasma display many resolutions do not seem interested HDTV. The evolution continues.
LCD – Liquid Crystal Display: Thin-design, size restrictions, a computer monitor good, clear pictures to show static display problems of moving images, many LCD HDTV can not. The evolution continues.
LCoS(Liquid Crystal on Silicon) – Improvement of LCD technology, may hold promise for future HDTV viewing, the problems of expensive production to continue, not yet completed development.
DLP (Digital Light Processor) – chip uses software and technology – exciting alternative display technology, outstanding HDTV display, eliminating most of the short coming of other technologies, moderate cost, and some viewers demand more "soft" l ' image, and the use of "color wheel," promising future – continued growth.
TV DisplayConfiguration
Aspect Ratio
The relationship between width and height of a TV or a monitoring program.
Aspect ratio can be applied to both the TV monitor () hardware or the format of the TV program.
Traditional – (4:3)-ratio, the display is 'looks square'. All analog TV programs are in the ratio of 4:3.
New "Wide Screen (16:9) aspect ratio, the display is rectangular.
Digital TV (SDTV), programs can be 4:3 or 16:9Report.
HDTV is always in 16:9 format.
As you can see, consumers must make a series of decisions long before making their final purchasing decision. Understanding the basics of HDTV requires us to speak with a number of strange-new-tech family "conditions.
Examples
Aspect ratio – width and height (4:3) or (16:9), refers to the TV and display TV programs.
Image resolution – 720 p; 1080-I 480-I / P, – and, recently,1080-p.
Progressive Scan – a method of display ( "p" in 720-p)
Interlaced scanning – Display method ( "i" in 1080-I)
D / A – A / D – digital-analog and analog-digital converter
STB – Set Top Box (aka: receiver, tuner, decoder or decoder)
OTA – over-the-air 'or' off-the-air "- refers to local TV reports
These are just some of the new words they meet.
The digital-TV-Enigma
As consumers begin their search forInformation on digital and HDTV, you will soon discover that what appears to be an empty "information." Trying to get useful, reliable information on what is required to purchase a digital television may seem difficult.
Asking questions based on HDTV means, for example, is the transition from analogue to digital television, that everyone is forced to buy an HDTV? or, What is the difference between SDTV and HDTV, or what is necessary to have high definition televisionsReception in your home? Now compare the different responses you receive, or in part the lack of knowledge about the sale of people.
Note: The seller must tell, or information on the missing features of digital television for sale to consumers who have submitted. This is a mandate of government.
In sharp contrast to the other extreme is the steady stream of "misinformation" and "disinformation." This flow of reliable information to the public inundated. The pathfor useful information and reliable, inaccuracies, errors and myths covered. And this is compounded by the misleading advertising and marketing tricks.
For example, here's a question repeated by confusing consumers about the transition from analogue to digital television:
"Can you tell me if it is true that" normal "TV is paused, and everyone will be forced to buy an HDTV?" I do not think that can not be … But ifWhen will it happen? "
Okay, that was really two questions …
The answer to the first, of course – no, not true. At least not in the nature of the issue. If it is true that "normal TV" is necessary (eg traditional analog NTSC TV goes) at the end, replaced by digital television ATSC, you can not buy an HD TV!
IMPORTANT NOTE: The change required by the FCC analog TV to digital TV refers is not, "high definitionTV! "
Note: If your analog television, you can use a converter, which make it possible to display on your TV, select the purchase / sale. There are good free with the purchase on the website listed below and while it is in print.
This highlights a major source of confusion, so that the public via digital television and HDTV. These are two distinct concepts, but they are often used incorrectly – as if they were interchangeable with the wordsthe same meaning. Are not the same, rename two distinctly different classifications of television. |
High definition television is "digital", HDTV, but only one (1) eighteen (18) "Digital TV format" means the standard ATSC.
It 'important for consumers to understand that "digital television does not mean" non-HDTV.
Digital TV is "standard-definition TV - SDTV – is not equal HDTV – High Definition Television.
Therefore, it is up toto inform each consumer her / himself the basics of digital HDTV.
But – Oops!
Do not take anything for granted, do not take statements at face value.
All sure to listen or read digital HDTV and compare with other sources.
Digital difference
The digital TV signals are encoded with instructions – (the same 'parts' of' ones and zeros "that works, your computer, and revive", CD and DVD ") – to send toDigital receiver (also: Tuner, Decoder or Set-Top Box "STB"), which in turn deciphers the code.
A digital TV receiver is not with the signal strength or what conditions between the set and give the stations involved. Until the signal to the receiver, the code can be read, is the digital TV is able to play a near-perfect picture – virtually identical to the original, back in the studio.
An important advantage ofreception of digital broadcasts is that bad a thing of the past. One reason cable TV caught on is because it provides clear television pictures, regardless of the position of the viewer. Viewers do not need regular adjustment of the antenna in an attempt to "tune" a weak signal from a remote transmitter to get a clear picture. Digital TV (DTV) will remove the snow "and" phantom "by weak signals distance, or block, causing transmission towers. If the analogTelevision does not receive a strong, undistorted signal from the tower, do not get a clear picture.
Weaken both analog and digital television signals, especially as travel far from the tower. On an analog TV, the picture deteriorates slowly increased by less than the distance between the tower and the receiver. However, the image on a set perfect stay digital until the signal is too weak for the receiverDistinction between one (1) and (0), at this point the image disappears completely.
This became known as "rock effect" – the image remains stable until, suddenly, "falls" the screen. This could send Morse code are compared. As long as the person at the other end, you can transfer the points and lines of being able to read the message. If they lose, the distinction between a point and a bit ', they lose the message. Acts of the same digital TVWay, but for the posting of points and lines, sends millions of (1) and (0) in a second.
As long as the TV receiver can read (1 and 0), shows an almost perfect picture. The bottom line … You will receive a picture at 100% or nothing at all. This means that for digital television viewer, who is no longer a matter of doing a "bad" picture. Either you have a photo or not. However, if you receive over-the-air OTA (Over The Air)Programs, it is essential that the antenna is closely aligned to the source – the tower of the station you watch.
Add an "H" to "= DTV WOW '! While our goal is to make the principles familiar with HDTV, we have so far mainly focused on digital television – DTV. What is HDTV – High Definition Television, and what is the difference between DTV and HDTV?
DTV is different from NTSC analog television technology used in the signal.And we have seen some of the reasons why digital is better than analog. But when comparing digital TV or SDTV (Standard Definition TV) for HDTV, the difference is like day and night, high-definition television and digital television – but … is important to understand that digital TV does not mean HDTV! HDTV is just one of (18) called ATSC formats including digital TV. Displayed in high definition televisions, the image on the TV screen beginsas an HDTV signal from the HDTV cameras, registered (or the film or converted to another format with HDTV equipment). The HDTV signal is transmitted to the HDTV receiver, and finally displayed on a monitor, HDTV-ready TV. But it must also follow the ATSC standard for high-definition television to make a "true" HDTV.
Note: 'more than likely that you will confront the apparent mis information that Digital TV is available in different configurations, the high-definition television. "Thisnot true! Can also say that until the TV responds to one or two criteria, or if the manufacturer, the use of engineering properties of "magic" that makes it – "almost" – HDTV. Again, this is not true!
If what you want is HDTV, you need to unplug the TV is concerned, is actually "true" high definition television. As you know, TV – HDTV? To answer this question, a little ' "of television technology base will be very useful.
It isuseful in understanding some of the basics of HDTV, providing information. After all, this is a discussion about Digital-HDTV – perhaps the most important "step forward" in the consumer technology for our society in more than one effect of the century!
The image you see on your TV screen consists of a series of horizontal lines. Shoot 'an electron gun' bundles of energy (light), making it a layer of phosphor within the CRT, so that illuminate it. Theseglowing lines create the image displayed on the TV screen. How are formatted, which resolution is used, what the standards are met, are just some of the factors that determine the type of TV screen you get.
TV Resolution.The as the image is displayed on the television screen's resolution is mainly the result. "In short, refers to the resolution TV ', how many horizontal lines on the TVScreen.
Note – Although the counting of horizontal lines, (is) in this case a resolution is considered "vertical" because the lines numbered from top to bottom – or vertically. Resolution TV is often described as the number of words total pixels' a product of the number of rows and the number of pixels per line '
Because the DTV standard Wide-Screen TV?
DTV set they sell in two, "aspect ratio". Aspect ratio refers to the relationship betweenhorizontal (width) measurement and the vertical (height) of the screen. This report is also used in the report, as the image is transmitted, and displayed on the screen. Both proportions are used in DTV (4:3) and (16:9). Unit that is high (4) units wide (3) units, and high (16), large (9) and unity. NTSC analog television has an aspect ratio (4:3), the screen looks almost 'square' because it is only slightly more width in height. For example, a(4 ') wide would have a height of (3').

This brief introduction to digital television and HDTV bases there) an overview deliberately simplified (like DTV is different from traditional analog TV, HDTV, and how different from digital SDTV, and some 'transition from analog TV to digital TV. This is just the beginninga better understanding of digital television. Now that you are familiar with some basic principles, you are better prepared for the start of 'investigation, HDTV is right for you.
