  Digital Visual Interface - Wikipedia, the free encyclopedia
The Digital Visual Interface (DVI) is a video connector designed to maximize the visual quality of digital display devices such as flat panel LCD computer displays and digital projectors.
However, in digital displays, instead of a scanning beam there is an array of pixels and a single brightness value must be chosen for each.
When the source is also a digital device (such as a computer), this can lead to distortion if the samples are not taken at the centre of each pixel, and in general the crosstalk between adjacent pixels is high.

 RLG Preservation Working Group On Digital Image Capture   (Site not responding. Last check: 2007-10-14)
Digital imaging techniques offer the opportunity to easily and quickly capture page images of library and archival materials, whether as a step toward preservation reformatting or as a means of improving access to materials or both.
The Working Group on Digital Image Capture is tasked to develop a pragmatic and implementable plan for the creation of a series of guidelines to be issued as part of a larger body of material on the creation and preservation of digital resources.
This might take the form of a nominal table of contents for a manual similar to the RLG microfilming handbooks; alternatively, the working group may decide it is sufficiently expert to begin to develop the guidelines themselves.

 Basics of Digital TV and HDTV
The FCC required the top TV networks to broadcast a digital signal in the 10 biggest markets by May 1999, which represent 30 percent of TV households in the U.S. The networks plan to expand digital coverage and phase out analog TV broadcasts entirely by the end of 2006.
HDTV uses a digital display, like your computer monitor, and the screen resolution is at least 1280x720 pixels, which is comparable to a high-end computer display.
These industries are currently working on ways of modifying their technology to incorporate the new DTV standard, and should have a solution in the near future.
