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.

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.

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.

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.

High Definition Glasses incorporate ChromaDepth? optics which are optimized for use with computer graphics. They are usually preferred by adults for most applications, including movie viewing, technical and medical applications, and the Web. C3D TM Glasses incorporate ChromaDepth? optics which are optimized for use with printed images, such as magazines, food packaging, and direct mail pieces.

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 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.

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.

A digital television is manufactured with the ability to support at least the minimum resolution required to display a digital signal. A digital-ready TV requires the addition of an external digital receiver to display digital content.

No. The Digital TV system used in the UK is the same resolution as analogue - 625 lines. However, the digital technology greatly enhances the picture quality you actually receive using this resolution. HDTV gives an even better picture, but requires new, expensive television sets. The American Digital TV system uses HDTV, and, due to the significantly higher costs involved, is not taking off nearly as quickly as digital TV in the UK.

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.

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.

A motor with a standard winding has a higher inductance with a higher force constant than does a motor with the high response winding. A standard response motor is used in systems with large mass and/or in systems that do not need high precision. A high response winding is used for high precision and/or highly dynamic motion.
