Intel Corp. [NASDAQ:INTC] said it developed new technology for Internet
service providers (ISPs) to significant speed their users' access to
World Wide Web pages. The software-based technology combines look-ahead
previewing with new compression algorithms applied at an ISP to reduce
time needed to download image-rich pages by "up to a factor of
times-two," an Intel spokesperson told Newsbytes.
The new technology, dubbed "Quick Web Technology" by Intel, is currently
under test by two very large ISPs -- Sprint and Netcom - - as well as
San Jose-based digital distribution company GlobalCenter.
"We have over 400 people developing technology in media content and data
compression, and quite a number of patents pending on this compression
approach," said Intel spokesperson Jon Jackson. "It looks intelligently
at pixels in each image to see what can be eliminated, and the rest is
compressed using different algorithms depending on the image. It makes a
dramatic difference in access times."
He said the most a user would notice might be a bit of fuzziness around
the edges of an image. "It is very hard to tell the difference," Jackson
added. "There's no color melting, and to the eye there's hardly any
discernable difference." Jackson said current trials will involve 1200
volunteer Internet users who will be asked to assess the system for
effectiveness, problems and the like. Intel has not yet decided how to
market the technology, he said, although the test sites are evaluating
it as a possible value-added service for users. The technology is
primarily intended for users with modems more than for those who have
very fast connections.
However, he added, if users like how Quick Web works in current trials,
Intel expects it will be extended for use in corporate intranets and
wide area networks (WANs) as well as on ISPs.
In practice, the software resides on an Internet connection server. When
a user clicks on a site, the ISP downloads the entire site onto a
preview server that resembles a proxy server but acts as a cache rather
than a firewall, Intel said. There, in real-time as a user downloads at
modem speeds, the system examines images for ways to strip pixels
without harming image quality. It then compresses the results. Asked if
stripping pixels from images might violate copyrights or destroy the
protection provided by image watermarks of the sort planted in graphics
by the Oregon-based firm, Digimarc, Jackson summoned an engineer to the
line who said Intel was aware of potential problems in that area. He
said Intel is working with all parties it knows of in the general area
of image protection on the Net. Stated Frank Gill, Intel executive vice
president and general manager for the Hillsboro-based Internet and
Communications Group: "Intel's new Quick Web Technology solves a real
problem for Internet users -- faster access to Web pages."
