Upscaling - Getting More Out Of Standard DVD

What is HDMI upscaling?

To maximize the quality of DVD for display on today's HDTVs, many manufacturers have introduced upscaling capabilities through DVI and/or HDMI output connections on newer DVD players.

Upscaling is a process that mathematically matches the pixel count of the output of the DVD signal to the physical pixel count on an HDTV, which is typically 1280x720 (720p), 1920x1080 (1080i), or 1920x1080p (1080p).

The upscaling process does a good job of matching the upscaled pixel output of a DVD player to the native pixel display resolution of an HDTV capable television, resulting in better detail and color consistency.

However, upscaling, as it is currently implemented, cannot convert standard DVD images into true high-definition images. In fact, although upscaling works well with fixed pixel displays, such as Plasma and LCD televisions, results are not always consistent on CRT-based high definition televisions
