Introducing the new amazing HDTV with digital sound.

By Lisa Tipton

Intro

Did you ever wonder how there are 10,000 pixels across a TV or 1,000 pixels down a TV? Well read my report to find out. This report gives you information about what the HDTV can do and a lot more other things lets read this report.     

What it is

What is the HDTV?

  HDTV is a T.V. It stands for high definition T.V that has tons more pixels. It has red green blue wires that make it so better. The HDTV is a popular T.V but very expensive but it has a thousand more dots like a regular T.V. the HDTV can help you see better, like when your trying to see a black and white movie you can see much much better. Regular TV has a lot of dots called pixels. But HDTV has about 7 times more. A regular TV has 337,920 dots. You add up all those dots and you get a nice picture.HDTV has 2,073,600 dots! You add up those dots and you get a really sweet looking picture.     

What does HDTV do?

What does HDTV do?

The HDTV can do lots of things it has better seeing and guess what the have an HD ipod that you can watch full length movies like black and white so on a ipod it is so much better. The HDTV cost 12,000 dollars wow thatÕs expense. The HDTV is so popular it is a very good TV it has about 10,000 pixels across and 1,000 pixels down I think thatÕs almost a million pixels wow thatÕs a lot. ThereÕs a really a big differences between the TV and high def TV. The difference between the is HDTV has the numbers of wires. And of course the cost

 

HDTV is amazing! Because HDTV uses more pixels (dots) than regular TV, it gives your eyes a better, smoother picture.

        

 

 

 

History of HDTV

According to wikipedia if you'd like to have HDTV capability someday but you don't want to spend that kind of money now, you can get an HDTV-ready television. These sets have the necessary resolution capabilities to display an HDTV picture but don't have the necessary decoder to interpret the HDTV signal. Out of the box, they function just like traditional televisions; you can buy a separate HDTV decoder that upgrades the set to display HDTV Timeline

1968: JapanÕs NHK initiates a project to develop a new standard in television.

 

1970-1980: An HDTV prototype is developed in Japan called the MUSE system.

 

Early 1980s: Movie producers are offered a high-definition television system developed by Sony and the NHK. This high-definition system allowed producers to record play and edit immediately and then transfer to film so that production time was considerably shortened.

 

1987: The NHK is invited by the National Association of Broadcasters in the United States to present their MUSE system to the Federal Communications Commission.

 

1990: General Instrument Corp. submits the first proposal for a completely digital HDTV system.

 

1993: The Grand Alliance is formed combining together the four separate American teams that had been working independently on the development of HDTV.

 

1993: Broadcasters speak out in opposition of HDTV saying that it would cost far too much and limit broadcasting opportunities.

 

1994: Rupert Murdoch also speaks out against HDTV saying that unused channels should be utilized to develop new stations, not to support the HDTV system.

 

1995: The U.S. Federal Communications Commission officially sets the standard for completely digital HDTV.

 

1998: HDTV products become available to consumers.

 

1999: FCC mandates that the top 10 markets start offering Digital TV broadcasts by May 1st of 1999.

 

2006: According to the FCC mandate, all stations are to be capable of broadcasting HDTV by the year 2006. At this time conventional broadcasting will be almost completely phased out.

 

Will it last?

Unlike BETA VCRs and 8-track players, HDTV is one form of technology that is being built to withstand the test of time.

 

With the decades of development and research that have gone into optimizing the HDTV system, this form of television is likely to endure for decades to come.

 

What can the HDTV do?

HDTV broadcasts. Some cable providers sell set-top boxes that will decode their HDTV signal. If your HDTV-ready television has a 4:3 aspect ratio, the picture will be cropped or letterboxed to fit the narrow screen size. For more information about HDTV and digital television, check out How HDTV Works. So I think your thinking wow yea that is so cool. The idea of introducing HDTV in the United States was met with mixed responses. In the 1980s, the National Association of Broadcasters in the United States invited NHK, JapanÕs public network, to present the ideas behind the MUSE system to the Federal Communications Commission. At that time, there were two groups that were adamantly against the introduction of HDTV in the U.S. The first group that opposed the introduction of this new technology was the Terrestrial Television Broadcasters. They were scared by the possibility of being excluded from the HDTV market because HDTV required more bandwidth (the amount of information sent through a channel or connection) than standard TV. These broadcasters worried because the channels that they already had license to would not be able to handle the bandwidth

Of this new form of television. With these two complaints in mind, the American government sought to invent a new form of HDTV. Groups of researchers and manufacturers were gathered together to form different teams. Each team would attempt to create an HDTV system that could fit into the existing channels that were used by broadcasters. After years of work, the separate teams of researchers and manufacturers decided to combine forces. This unity gave birth to a new group known as Grand Alliance. It has been nearly 80 years since the first public demonstration of television took place in a crowded laboratory in London. Since that time television has advanced from blurry black and white pictures to stunning high-definition images with life-like depth and realism. How were these achievements made? More importantly, what should we expect in the future as we approach television's first centennial?

 

The price of the HDTV and the Equipment and Signal.

According to howstuffworks.com The DTV transition is not the first change to the TV signal. In 1946, the National Television System Committee (NTSC) began setting standards for American broadcasting. In 1953, NTSC standards changed to allow color television, and in 1984, they changed to allow stereo sound.

 

Those changes were different from the DTV switch because they were backwards compatible -- you could watch the new signal on your trusty old TV. With DTV, you'll need some new gear, and the gear you choose will affect whether you can receive and view high-definition video. You can learn about buying a DTV set in How Digital Television Works -- here, we'll focus on HDTV. *  An integrated HDTV, which has a digital tuner, also known as an ATSC tuner, built in. If a station near you is broadcasting in HDTV, you can attach an antenna to an integrated set and watch the station in high definition.

    * An HDTV-ready set, also called an HDTV monitor, which does not have an HDTV tuner. HDTV-ready sets often have NTSC tuners, so you can still watch analog TV with them. This is the option for you if you want to have HDTV capabilities later on but aren't ready for the financial commitment now. Your picture quality will still be better than on your old TV, but it won't be high definition until you get an HDTV receiver.

 

Designing and building an HDTV that could display all of the ATSC formats would be virtually impossible. For this reason, HDTVÕs have one or two native resolutions. When the TV receives a signal, it will scale the signal to match its native resolution and de-interlace the signal if necessary. A good rule of thumb is to choose a set that has a native resolution matching the signals you plan to use most often. Film fans will generally want displays with the highest possible resolution. Sports fans will generally want displays with the highest possible progressive frame rate. When you've found an HDTV with a screen size, aspect ratio and native resolution you want, you'll need to make sure the equipment you already own will work with it. If you already have a DVD player, a DVR, game consoles or other equipment, make sure that they can connect to the TV directly or through an audio/visual receiver. Many HDTVÕs have High-Definition Multimedia Interface (HDMI) connections, which can transmit audio/visual signals to the TV without compression. In some cases, you can use adapters to make your equipment compatible with your set. An antenna - Depending on your location relative to the stations you want to watch, a set of rabbit ears might do, but you might need a rooftop or attic antenna. You can buy an antenna that's specially made for digital signals, but any reliable VHF/UHF antenna will work.

0.      Cable - Keep in mind that digital cable is not the same as HDTV. You'll need to check with your provider to determine which packages include HDTV stations. You'll also either need a set-top cable box or a Cable CARDª to allow your television to receive and decode the cable signal.

Satellite service - As with cable, check with your provider to determine which plans and stations use HDTV signals. You may need a different satellite dish and tuner to receive HDTV signals via satellite. But the sad part about it is High-definition television (HDTV) is a digital television broadcasting system with greater resolution than traditional television systems (NTSC, SECAM, PAL). HDTV is digitally broadcast because digital television (DTV) requires less bandwidth if sufficient video compression is used. HDTV technology was introduced in the United States in the 1990s by the Digital HDTV Grand Alliance, a group of television companies. [1][2] HereÕs the sources of the HDTV The rise in popularity of large screens and a projector has made the limitations of conventional Standard Definition TV (SDTV) increasingly evident. A HDTV compatible television set will not improve the quality of SDTV channels. To display a superior picture, high definition televisions require a High Definition (HD) signal. Typical sources of HD signals are as follows:

 

    * Over the air with an antenna. Most cities in the US with major network affiliate broadcast over the air in HD. To receive this signal an HD tuner is required. Most newer high definition televisions have an HD tuner built in. For HDTV televisions without a built in HD tuner, a separate set-top HD tuner box can be rented from a cable or satellite company or purchased.

    * Cable television companies often offer HDTV broadcasts as part of their digital broadcast service. This is usually done with a set-top box or Cable CARD issued by the cable company. Alternatively one can usually get the network HDTV channels for free with basic cable by using a QAM tuner built into their HDTV or set-top box. Some cable carriers also offer HDTV on-demand playback of movies and commonly viewed shows.

    * Satellite-based TV companies, such as DirecTV and Dish Network (both in North America), Sky Digital (in the UK and Ireland), Bell Express (in Canada) and NTV Plus (in Russia), offer HDTV to customers as an upgrade. New satellite receiver boxes and a new satellite dish are often required to receive HD content.

    * Video game systems, such as the Xbox (NTSC only), Xbox 360, play station 2 (Gran Truism 4) and Play station 3 can output an HD signal. The Xbox Live Marketplace and Play station Network services offers HD movies, TV shows, movie trailers, and clips for download to their respective consoles.

    * Most newer computer graphics cards have either HDMI or DVI interfaces, which can be used to output images or video to an HDTV.

    * Two optical disc standards, Blue-ray Disc and HD DVD, can provide enough digital storage to store hours of HD video content. DVDs look best on screens that are smaller than 36 inches, so they're not always up to the challenge of today's high-definition (HD) sets. To store and play HD movies, you need a disc that holds more information, like an HD-DVD. A DVD holds about two hours of standard definition video, but an HD-DVD can hold about 48 hours.

I hoped you liked my report and I hope you things about the high definition TV.
