In the days of our old CRT TVs, then different formats could just scanned onto the TV surface, hence we got a picture whether it was from different formats, like PAL and NTSC.
PLasmas, LCDs etc work differently. They have a a matrix of points, x by y that need to be addressed and any signal that needs to shown has to activate all those dots or pixels. This is fixed as opposed to CRT. Each plasma / LCD panel has different resolutions, so my plasma is 1024 x 768, many LCDs are 1366 x 768. There are many variations here.
The two biggest formats for HD are 720p, which is essentially 1280 x 720 and 1080i is 1980 x 1080 but only every other line. If 720p is also the resolution of you display then it displays without any extra work. However most screens will do some extra processing so that 1080i is displayed correctly on your 136 x 768 panel. (It is deinterlaced and down sized).
SD Standard Definition DVD is 720 x 576 (or 480 for 'NTSC'). This will have have to scaled also to fit the plasma / TV. Upscaling DVD take this 720 x 576 (or 480 for 'NTSC') and scale it to fit 720p or 1080i. This is the same resolution as HD but is NOT HD. These things should not be confused. If done well and the screen exactly matches the upscaling to a panel with 720p (or 1080i) resolution then the idea has some merit BUT and this is a BIG BUT, most screens do not represent 720p so it actually does more harm than good as the DVD does the scaling operation and so does display. It is best to do just one scaling operation and to do it in the best place possible. This is why the new Arcam quoted above may well have a technological lead with ABT scaling.
The bottom line is if you buy an upscaling DVD, the upscaling bit is essentially the same as the upscaling bit already in your display, so you are buying a gadget you already have. Best to just buy / use the best one. The simplest method is to sent 576p to you display and let that do the scaling. For MANY operations, this is very sucessful, for those that bother to look. The scaling is most upscaling DVD players is basic at best and even favourites like Oppo really use quite a basic chip.
