Definition LCD

The LCD screen with a diagonal of 32 inches , according to " picture" the most established television version in German living rooms . LCD The acronym derives from Old English and means " Liquid Crystal Display" . This refers to liquid crystals whose orientation is controlled by electrical impulses. Benefits arise primarily in the light yield , but also the power consumption is significantly lower than competing plasma process . In plasma screens small gas discharges take place where plasma. This plasma excites phosphors , thus creating colored light. This plasma TV for a long time had a clear advantage in terms of the representation of black and dark colors

The LED is

The abbreviation LED in German means as much as "light-emitting diode." LEDs are replacing the TV from the conventional fluorescent tubes in LCD TVs and offer a much cheaper and more efficient way of supplying light . By LED can be a background control dynamically and individually. In other words, better black levels are achieved by the black areas of the image are simply not illuminated.

There are already first OLED Display (organic light emitting diode) - the LEDs are made ​​from organic semiconductor materials , the light itself so much that can be dispensed with a backlight . However, the material for this technology is not yet ready for the market larger displays and short-lived.

It depends on the receive path

To receive high-definition television , there are several possibilities: The widest range of channels , there is usually via satellite. ARD, ZDF and Arte , as well as the private channels that offer HD , all have received over a bowl. When cable TV , the number of received stations depends on the cable provider from: Germany, the largest cable provider has until the end of January an agreement with ARD and ZDF, the HD offering the pay channel Sky do however many cable providers subscribe. The channels are broadcast via the high-resolution cable connector, should ask their provider interested in HD . Also a very fast internet connection - DSL least 16 000 , it should already be - is it via IPTV possible to receive high-definition television .

Private broadcasters such as RTL , ProSieben, Sat.1 or pay TV channel Sky broadcast their HD channels only encrypted. So the providers hope for significant control over their contents : for example, they can prevent such recordings . Currently, RTL, VOX , ProSieben, Kabel Eins Sat.1 and radiate only via the Astra satellite operator and a joint platform "HD +". Spectators watch the first 12 months free . After falling at a cost of 50 euros per year . Three options are currently under discussion or are already available :

A special satellite receiver with integrated HD + card to recognize the logo "HD +". Some of these devices are already on the market. Two of the Stiftung Warentest already in the current test satellite receiver ( test 02 /2010 ) were tested.
Another possibility is to be offered during the first quarter : a single HD + card with a matching module for the so-called CI + slot. Here then is sufficient a TV with the right receiver and CI + slot , an additional device is required. However, only very few TVs are certified for it.
Paid cards with HD + modules are also announced to upgrade for receiver with so-called CI slot for this year . These will be what exactly , but is not yet known .
In all three variants, viewers must expect that , for example, a movie can either does not absorb or advertising can not be skipped .

Receiver. For high-definition TV an HD -compatible receiver is imperative . For example, reaches an older satellite receiver without HD not .
TV . Devices with the logo "HD ready" can represent high-resolution images, but do not contain a receiver . Wearing a device , however, the logo "HD TV" is an integrated receiver .
Transmission path. But beware: Few television receivers have for all major transmission paths on board , so for cable, satellite and antenna , the latter , however, in Germany does not matter. However, the receiver has to match with the transmission path. Example: If the TV is integrated only a digital cable receiver , but the audience looks over satellite, an additional HD -compatible satellite receiver ( test 02 /2010 ) is needed - even if the TV supports the "HD TV " logo .
External receiver . An additional receiver must be the TV as well as HD-ready . The buyer to recognize the logos "HD TV" or " HD + " . Unlike a built- in TV receiver external device often offer additional options such as recording functions.
Tip: flat screen TV with the best picture quality for high-definition television , see the Product Finder TV .

Lost and found

Who has all the right devices and receives a digital television signal , which was found during a search of the new channels like ZDF HD . Before the start of the Olympic Winter Games run on ARD and ZDF still testing programs , but can already storing in your own program selection . Savvy viewers can also directly enter the data from the respective broadcaster : About the satellite operator Astra , for example, ARD, ZDF and Arte HD on leave in the position 19.2 degrees East and the receive frequency 11.362 GHz.

Conventional TV still possible

Do not worry: Even without watching high-definition technology television viewers only times more easily . All HD devices can receive and process standard signals. Who , for example, a flat screen TV without a built-in or external HD receiver at home , can continue as before so its usual broadcast - just not high definition. Owners of old tube TVs also need not worry : The conventional range , the transmitter continues in parallel .

The activities for high-definition television were primarily driven in the U.S., where the Federal Communication Commission (FCC) and the American Television Standards Committee (ATSC ) accompanied the standardization. According to the U.S. two standard image formats have been standardized according to BT.709 with different resolution : 1,920 x 1,080 and 1,280 x 720 pixels , and it is shown the image points.
Identification of the various options for HDTV
IDENTIFICATION OF VARIOUS TYPES HDTV encyclopedia , compendium , computer , it, electronics
In Europe, an alternative concept with different image resolutions was drawn up as part of a Eureka project, from which eventually the two already mentioned image formats are selected. The aspect ratio of HDTV is 16:9 , the refresh rate is 24-60 frames per second. Both HDTV formats are specified using the line count and refresh rate , separated by a slash . That with the lower resolution than 720 /25 and the high-resolution with 1.080/25 . With additional letters after the number of lines the scanning is made clear : " i" stands for interlaced , so for interlaced , "p" for progressive scan and psF for Progressive Segmented Frame. The variant identification can then look like this: 720p/30 or 1.080i/29 , 97 So 1080i is an interlaced display with a resolution of 1,920 x 1,080 pixels, which corresponds to the so-called full HD . Is shown in the same resolution progressive scan , then it is referred to as 1080p .
For video compression using MPEG -2 HDTV , but increasingly the more efficient video codecs such as H.264/AVC and Windows Media Video ( WMV HD ) are used , the MPEG -2 are superior in compression and image quality. These are provided in the DVB-S2 standard .
In addition to other formats for HDTV digital TV have been standardized by the ATSC , the Enhanced Definition Television ( EDTV) , standard definition television (SDTV ) , low definition television ( LDTV ) and the extremely high-resolution ultra - HDTV ( UHDTV ) .
For the transfer and storage of data streams definition video ( HDV) and AVCHD developed two digital video formats with high .

HD Ready LCD TV



Consumers shopping for a new television may find the various types and options on modern sets a bit overwhelming. One of the new sets that may be unfamiliar to shoppers is the HD LCD TV. Although these televisions have been around for several years now, many people are just now replacing an old television unit and have never researched this newer product.

The HD in the HD Ready LCD television label stands for high definition. This results in a picture so clear that it is easy to see the expressions on the faces of sports fans in the stands during a game. Those who watch movies also find high definition wonderful because the picture fills the screen entirely during the show.

This picture quality and clarity in an HD Ready LCD TV comes in part from technology that allows it to receive a broadcast in 1080 resolution. The HD LCD TV sets display one of the sharpest pictures available in a television set. If the HD technology is not designed into the unit, consumers who purchase televisions must also buy an external device to receive the brighter high definition resolution.

The LCD designation in the HD LCD TV line stands for liquid crystal display. When liquid crystals are pressed between two flat plates of glass, electricity can then be passed through the crystals to produce brilliantly colored pixels with highly refined edges to give sharpness to the images that appear on the screen.

When purchasing an HD Ready LCD TV, consumers are getting both of these outstanding technologies incorporated into the same set. Most find that the HD Ready LCD television's picture is comparable to the pictures found on a plasma television, but the HD Ready LCD TV may have some added benefits. The HD Ready LCD television's flat screen takes up very little space, and it is quite energy efficient.

Also, the HD Ready LCD TV maintains its picture quality over time so maintenance costs are reasonable. It is lighter than other types of televisions so moving it is much easier. The only way to get a true idea of how much different this new technology is from the others available is to view it personally. Researching the various brands and models online, however, is an excellent way to narrow down the choices. Then, prices between these brands may be compared online or in a retail store.

HD Ready LCD TV sets may be purchased with screens as small as fifteen inches or as large as fifty-two inches for those who want a movie theater type experience. HD Ready LCD televisions have also been on the market long enough to be quite reasonably priced. Most of these sets even come equipped with Dolby surround sound to give the ultimate in viewing experiences. Some brands have special motion technology to keep fast action scenes from blurring. This is important technology as special effects evolve to give the viewers greater thrills and more realism than in the past.
