How do upscale conversion DVD players work?

I'm thinking of buying a new DVD player for my TV and I was wondering how these work.

They use a mathematical aglortithm to try and work out what should be in the extra pixels. Generally the picture quality from an upscaling DVD player will only be better if the technology in the player is better at upscaling and de-interlacing than the processing chip in the flat panel as it has to upscale to fit the higher screen resolution anyway.

Cheaper panels just do this by filling in with like pixels, like zooming into a photo in photoshop hence you can get a blocky looking picture viewing a standard def source.

One of the better chips at doing this in DVD players is DCDi by Faroudja. Look for the DCDi logo on the DVD players literature.
