JPEG2000 will be on the market within a few months, a standard that allows you to download images hundreds of times faster than now from the Internet.

Innovation has come hand in hand with Michael Marcellin, of the University of Arizona, and researchers David Taubman, of the University of New South Wales, in Australia, and since its appearance in the early 1990s, it has been the first major novelty that has been made to the JPEG format. The JPEG format compresses images, making it the most widely used format for sending images by email or downloading them from the Internet. In return, the image loses some quality. According to the researchers, the JPEG2000 standard will allow to compress images 50-100% more than today, without producing pixelations or losing quality.

The tests carried out at the university showed the speed of the new standard. With a 56 Kbps modem the JPEG system has lowered for a few seconds the image that would go down in 10 hours. And the JPEG2000 standard does not lower all the information, but what we need at all times. If you do not want to see the image on screen, it detects the size necessary for it and downloads the information necessary to complete it. If you want to print the image, the amount of information will be adjusted to the resolution offered by the printer. That is, the JPEG2000 standard allows images to be adapted to needs, speeding up information traffic and saving time.

The extension of the new standard compression is jp2 and in order to use it, browsers need a new plug-in that is now available for free on the Internet. The manual is also available.
