HD signal can contain up to around five times the picture information compared to standard definition (SD). Analog TV--what we've been watching for more than 60 years--has a resolution that's equivalent to about 640x480 pixels. An HDTV program, on the other hand, has a resolution that tops out at 1,920x1,080 pixels, more than six times as sharp in best-case scenarios. The difference is obvious.

Digital television (DTV) is a transmission method that will continue to be used to broadcast high-definition signals. In the same way that audio quality was improved moving from analog music cassettes to Compact Discs, a similar change is happening to television. High Definition broadcast also includes Dolby 5.0 stereo surround sound signal that helps bring out the total home movie theater experience.

HDTV stands for high-definition television, and it marks the biggest leap forward for television since color TV made its debut in the 1950s. HDTV images are more than twice as detailed as standard analog TV, delivering rich, realistic images, as well as multi channel, movie-theater-quality surround sound. HDTVs can display both regular and HDTV images, but they need HD sources to look their best.

No. A digital receiver or digital cable box are all that is necessary to receive the additional channels on your basic television set.

Digital television will allow us to broadcast programs in much higher resolution or clarity than today's television. This is called high definition, or HDTV. Viewers at home will be able to receive high quality, crystal clear pictures and enjoy a true home theater experience. These visually stunning pictures will be displayed in a wide-screen format (16 by 9 aspect ratio) as opposed to today's basically square box format (4 by 3 aspect ratio.

There is a major difference between High Definition and Standard Definition programming and between Digital and Analog content that can greatly affect...

When programs are not being broadcast in high definition, digital television will allow each station to transmit four or more programs simultaneously. Standard Definition Television (SDTV) multicasting is made possible by compression techniques not available with today's analog system. SDTV offers a higher quality picture than we have today, along with stereo sound. [Top of Page]

The POSIX.1 standard specifies application programming interfaces (APIs) at the source level, and is about source code portability. Its neither a code implementation nor an operating system, but a stable definition of a programming interface that those systems supporting the specification guarantee to provide to the application programmer.

The Xbox does support high definition television, up to 1080i resolution. To get HDTV you will need to purchase the official Xbox High Definition AV Pack. This feature has been disabled from the PAL Xbox but I have left the inclusion of this in the FAQ as some of you may have an imported Xbox.

It has received praise for being as good as or better than commercial alternatives. For example, see http://www.eweek.com/article2/0,3959,652977,00.asp

That is a great question. We are occasionally experimenting with passing HDTV signals over the current system to see how it goes. It will be several years though before we are offering the local TV stations or other networks in HDTV. Part of the issue is channel capacity and cost. For some period of time we may have to offer both analog and digital signals of networks while people transition to the newer digital television sets.

These glasses, collectively referred to as ChromaDepth? Glasses, incorporate micro-optic lenses that optically convert CyberHologramsTM and Standard images into true holographic images. Chromatek Inc. is the only manufacturer of these lenses in the world.

They optically transform color information into holographic 3-D using the world's most precise micro-optics ever mass produced. The ChromaDepth? Glasses are a general purpose hologram that displays the holographic content of color images. An image designed to be viewed in this way is called a CyberHologramTM . The Glasses optics plus a CyberHologramTM image form a complete hologram. For more information see our ChromaDepth? Primer and CyberHologramsTM pages.

DTV is the umbrella term used to describe the digital television system adopted by the FCC in December 1996. HDTV is a type of DTV service. HDTV provides high resolution programming in a widescreen format. A current analog TV picture can provide resolution of up to 480 horizontal lines. An HDTV picture can provide resolution of up to 1080 lines, providing improved picture detail. Aspect ratio is a comparison of screen width to screen height.

Yes. The Kaleidescape System has been designed for the anticipated widespread availability of HD content. The massive disk capacity of the Server is ideal for storing HD movies. A few HD titles are already being distributed by Kaleidescape pre-loaded on every new Kaleidescape System, and more will be available in the future.

High Definition Television (HDTV) will not dramatically change the process of creating descriptions. If there are changes, they will most likely be in how descriptions are transmitted.

This is false. The Xbox 360 supports many different connections to many types of televisions, from composite connections for standard televisions to component and VGA connections for high definition televisions and computer monitors.

Satellite television reception is clearer than cable reception, for starters. The basic satellite package offers you more channels as well. You can get local channels from either service. If you love movies or sports, satellite television typically offers you a wider range of programming choices as well. Satellite TV is often cheaper than cable, so for the money you get an excellent deal.

No other radiant floor heating system enjoys all the advantages that EasyFloor provides. EasyFloor is easy to install, is non-structural, is totally quiet and up to 60 percent more efficient than other methods. In addition, when doing a cement or gypsum pour, large amounts of moisture are released and can possibly damage or destroy wallboard and paint jobs. This is not a problem with EasyFloor.
