Paper Abstract

We describe a Library of Congress experimental project involving the in-house production of a digital videodisc containing digitized and compressed video still frame images from the Library's collections of prints and photographs and other sources. The medium used was a 130 mm (5 1/4 inch) write once-read many (WORM) digital optical disk with a capacity of 200 megabytes per side. This equated to about 1800 images per side. We demonstrated that component (RGB) digital encoding combined with a nominal 10 X compression yielded high quality displays which, with rare exceptions which are discussed, were indistinguishable from source video images on a conventional analog videodisc. We further demonstrated that 100 successive generations of digitized and compressed video could be produced with no discernable impairment to the image. We discuss the objectives, the experimental configuration, and applications of this system.
