What is TNT HD, HDTV, LED, LCD, Plasma, HD Ready, Full HD ...? Photovoltaic Solar Energy
Terrestrial or DVB-T Digital TV is the transmission of moving pictures and associated audio (TV) via a digital (binary coding) and through a network of terrestrial repeaters.
digital coding provides several advantages. These include first, the ability to compress the signal, which means it requires less bandwidth for transmission. As a result, you can make more efficient use of spectrum. After her multiplexing may be issued more channels - digital system that are renamed "Digital Program" - In the space formerly employed by one, now called "multi-channel digital" or "multiplex". The number of programs transmitted in each multi-channel compression ratio depends on the employee. On the other hand, devote the surplus to other uses spectrum. Compression has also viable broadcast signals in high definition television (HD or High Definition in English), which require more bandwidth than standard definition.
The second advantage provided by the digital encoding is improved picture quality and sound at the time of receipt. Since both are digitally encoded, ie, logically, and not in proportion to the original information sources (analog TV), when any signal distortion, thus affecting the quality of reception, that may be corrected by the receiver. It identifies the error signal and corrects it. This translates into better quality. Worth mentioning that the digital signal is more robust than analogue, ie not more resistant to interference. Both are electromagnetic signals of the same nature, and capable of being distorted by electric or magnetic fields, as weather conditions, etc. The difference, as stated, lies in the way of encoding information. The digital encoding is logical algorithms that allow then to identify and correct errors.
DTT transmission is carried out following the technical parameters established by different technological standards. There are various and their use by states responding to their ability to create standards to its geographical location and membership in the sphere of influence of state standards makers. The European DVB-T used in the European Union, Australia, South Africa, Namibia, Uruguay, Panama, Colombia and Turkey. This system transmits audio, video and other data through an MPEG-2 stream, using COFDM modulation.
How does high-definition television?
Currently there are TVs with Digital Tuner Freeview TD standard and high definition to receive HD images via satellite.
broadcasting signals There are three ways to receive a television signal in HD:
• Terrestrial Broadcasting: currently exist in Spain more than 30 channels that are broadcast by digital terrestrial television. To view you must have a digital tuner.
• Cable: many cable systems offer HD movie channels and regional sports of payment as well as some local HD broadcast channels.
• Satellite: the satellite television channels continually expand its offerings in high definition. There is also now programming on Art, Music, Entertainment, Extreme Sports and Travel in high definition available throughout the day via satellite. You need a special HD receiver to satellite. The availability of channels broadcasting in high definition varies depending on the local market and the satellite provider.
What is the difference between analog and digital broadcasts?
Analog broadcasts are limited to the transmission of image and audio channel to occupy a 8MHz of bandwidth. Besides analog broadcasts are subject to interference and noise. Digital emissions, use that same bandwidth to transmit up to 4 channels or services in Standard Definition Television, up to 5.1 audio channels for each service and even information data, whether for interactive applications or applications and updates service software. These signals are free of noise and interference and the reception quality is the same quality at the time of retransmission. On the other side instead of issuing 4 channels in standard definition, it can issue 2 and 1 standard-definition HD 1080i or 720p. Or two in high definition 1080i or 720p, or a channel in full HD 1080p. Broadcasting
With analog broadcast signals, the reception quality is directly related to the quality of the signal. However, in the case of digital broadcast signals, the quality is the same on your TV regardless of the strength or weakness of the signal strength, unless there is no signal. Image Processing
TVs old and new are composed of a series of horizontal lines, which in turn are made up of tiny dots, called pixels. The number of lines and points determine what is called "resolution." Resolution
DTT allows 4-channel broadcast in standard definition, or 2 channels in standard definition and 1 high definition 1080i or 720p, or 2 in high definition 1080i or 720p, or a channel in full HD 1080p.
These differences are also reflected in the shape of the signal: the signals are SD "standard" form (with an aspect ratio of 4:3) and HD signals are formatted as "widescreen" (with an aspect ratio of 16:9). HD is different on this issue further, issuing two signal formats: 720p and 1080i x 1280 x 1920, interlaced first and the second progressive, although it is virtually impossible to distinguish any difference.
LCD TVs LCD TVs The LG are set to see movies. Full HD processing takes the low resolution analog signals to levels close to high definition (1080p), and reproduces images precise showing the original images without motion blur. It also incorporates the Intelligent Eye technology, which optimizes brightness and contrast adjusting to ambient light. The LG Full HD TVs also incorporate TruMotion 100 Hz, which doubles the frequency of updating and allows viewers to watch high-action sequences with no motion blur or trails. In addition, our exclusive Dimple Speaker design provides clear and powerful sound at any volume, creating a completely thrilling cinematic experience every time.
Plasma TVs with plasma TVs LG, viewers enjoy startling clarity and unprecedented detail with deeper blacks and superior shadow detail. Dual XD Engine technology generates an optimal quality for all video image quality and provides a clearer overall picture. These effects are enhanced further with our Super Bright Panel, it also provides a brighter image quality and crisp.
'Plasma or LCD? What fits my needs?
Both LCD and plasma TVs are sleek, lean, innovative and can show striking images in high definition with an incredible display from any angle. But which of the two technologies is best suited to your needs?
What is a Plasma screen?
Plasma TVs are large screens that use conductive plasma to produce colored light. The gas in the plasma state reacts with phosphors in each sub-pixel to produce vivid colors and ultra-clear picture.
Plasma screens generate their own light to produce a stunning contrast ratio and images with a smooth and precise movement. This is one reason why some consumers prefer plasma displays to LCD TVs for watching sports and movies action. Plasma displays are also known for its deep, rich blacks and incredible color accuracy, which makes them the ideal for watching movies, where dark scenes are common.
For various reasons, many experts believe that plasma screens are the best choice for home theater environments. First, plasma screens tend to perform better in controlled lighting environments, such as exhibitions at home. Secondly, plasma displays also have a slightly wider viewing angle than LCD screens, so you can enjoy precise, vivid picture wherever where you're sitting in the room.
What is an LCD screen?
LCDs are digital TVs with a fixed pixel structure. Each pixel has three sub-pixels of red, green and blue. The image on an LCD screen is generated by a backlight behind the display panel. The image goes through a polarizing filter and each sub-pixel has tiny crystals that create different levels of brightness.
One advantage of LCD TVs is the wide range of sizes, ranging from 15 to 55 inches. Smaller LCD TVs are available in 4:3 and widescreen formats. TVs with larger than to 22 inches are only models that allow high-definition widescreen.
LCD TVs also offer versatility. Its wide range of sizes for a broad range of prices for all budgets. Furthermore, because LCD televisions use adjustable backlight technology, the image does not deteriorate in bright rooms or environments where lighting conditions can not be controlled. LCD TVs also offer superior performance for video and computer graphics. In other words, regardless of content displayed, LCD TVs offer impressive high-definition image.
TVs with LED technology
A TV with LED technology is an LCD TV to replace fluorescent lamps and LEDs.
A fluorescent lamp illuminates a group of lines equally, regardless of variations of gray tones or colors in the line. As always some light leaking into the black areas by decreasing the contrast of the TV. The LEDs, however, illuminate separate areas of the panel. In this way more independently controls the backlight, improving contrast in the image.
The main advantages of LED TVs are dimming located in smaller areas of imaging and Independent evenly distributed backlight bright images, much higher contrast and more accurate reproduction of colors.
What is high definition digital television?
The high definition digital television (HDTV) is the technology that allows the antenna signal in high definition. Moreover, we are in the middle of a national transition from the old analog TV and fuzzy towards the crystal clear High Definition Television.
high-definition digital TV: the future of TV
The current digital age and the nearest future present a context where broadcasters can offer their programming via high-definition, which can display movie-quality pictures and sound that far exceed the capabilities of the current system. Networks can continue broadcasting on multiple resolution formats simultaneously (so-called "multicasting"), but with all the new DTT programming; there will be ever increasing choice to enjoy high definition exclusively on your TV.
Important things to know:
There are five types of HDTVs: vision tubes direct normal format, LCD, plasma screens and projection units front and rear, for those who need independent displays. Regardless of the options, remember that high-definition refers to the resolution, the number of horizontal lines that can be displayed on the screen, not the display technology which is based on the TV.
Virtually all television stations are now broadcasting digital and is expected to cease analog broadcasts on April 1, 2010. To smooth the transition, manufacturers and service providers are making reasonably priced decoders to reduce the quality of digital signals and convert analog signals. Therefore, analog sets will continue receiving the broadcasts when analog broadcasts go away. However, upgrading to digital TV is the only way to enjoy all the important advantages of digital broadcasting (such as theater-quality sound and digital services and additional benefits as soon as you offer).
Digital cable television is generally not high definition. This is a common misconception. Digital cable is usually analog television quality has been digitized and sent through the cable, a digital signal. The video quality and image of the digital cable is superior to standard analog cable, but still well below the brightness of the picture in high definition. That said, some cable systems offer several channels in high definition. Today
issued more than 200 hours of HDTV each week, including 70 hours of free television programming for major networks, which continuously adds new programming.
What is the difference between analog TV, DTV and HDTV?
The high definition digital television has 5 times more visual detail than analogue television within the same broadcast channel, while removing snow, shadows and interference. Televisions (the combination of a screen and a receiver) in the digital world are known as DTV. The DTV offers three performance levels: standard definition (SD), enhanced definition (ED) and high definition (HD). All currently marketed DTV can receive DTV signals in SD, and only those who have an HD or MPEG4 digital tuner can receive HD channels.
SD TVs TVs that receive all DTV broadcasts and display 575 interlaced lines of resolution presented in an aspect ratio of 4:3 (Square-shaped analog TVs today). This is the same resolution (or "visual detail") with the existing analog television systems. ED TVs
TVs that receive all DTV broadcasts and display less than 720 lines (for example, 575p) TVs are called "enhanced definition." These televisions are offered in widescreen format (16:9) or standard (4:3), but the image displayed is always widescreen, the same resolution of current DVDs.
HD TV and FULL HD READY
TVs that receive all DTV broadcasts and display 720 (HD Ready) or 1080p (Full HD) progressive lines (rows of pixels measured vertically), TVs are called "high definition" (including 720p, 1080i and 1080p). High definition televisions are offered in widescreen format (16:9) or standard (4:3), but the image is always displayed in widescreen format. This type of TV is the fastest growing segment of the market, by providing the best performance and adapt smoothly to the signal quality of most chains.
Why buy an HDTV?
There are many reasons for buying a TV high definition, from the stunning image quality and improved programming to HD audio, as well as the upcoming national transition to digital technology. Image quality
Have you invested in quality entertainment? Get more vibrant colors, deeper blacks and sharper the image when watching your TV shows and movies in HD. Resolution
TVs old and new are composed of a series of horizontal lines, which in turn are made up of tiny dots, called pixels. The number of lines and points determine the "resolution" a TV, or clarity of the image. Widescreen
Enjoy better picture quality and larger size, and a cinema-style display with a widescreen TV. With the 16:9 format, you get all the benefits of "true" widescreen TV. And do not forget that digital widescreen is the future of television. Pass ratio of 4:3 to 16:9 format and you will see the difference. Surround
Many HD programs are broadcast with Dolby Digital 5.1 surround sound, the same quality of high-fidelity sound that can be found in theaters with Dolby Surround. HD Programming
There are currently high Definicon channels via satellite, cable and even through the TDT, although the latter in evidence and not on the entire English territory. Yes it is expected that from April 1, 2010, starting with high-definition broadcasts in Spain in some emission lines.

A Brief History of Nearly Everything
I used the Christmas holidays to finish a book for some time had begun. It is "A Short History of Nearly Everything" by Bill Bryson. I loved it.
If you like science, or are you l @ s that you want to know the why of things, but I dread to open a science book for fear " level "you may have, this is your book.
With a very interesting reading, and quite a few examples clarifying, once finished understand much of this field of knowledge.
is a best-seller worldwide, which speaks volumes for them, because few scientific books that achieve this status.
