HD Upscaling
HD Upscaling is a way in which manufacturers mathematically match the pixel count of the DVD players output to the pixel count on an HDTV 1280x720 (720p) or 1920x1080 (1080i).Its important to remember that it will not deliver true HD, but will offer a enhanced picture quality (in terms of colour and sharpness).
This means that you can get enchanced quality from your existing DVDs without the need to go out and buy them all again on HD-DVD or Blu-ray format.
