They make a 1080p TV and it has a scaler to upconvert everything to that. Appears they have two scaler designs in their basket of widgets creating a step up model that uses the same scaling as their 1080p product and then downscales to the pixel matrix of the display. The claimed benefit here would be that the 1080p scaler works with more pixels creating less errors on the way up and when down scaled to 768. There may be something to it and would not know without testing.
How much extra do they want for this feature?

Cost....1080p chip TV is approx $130-$150 more.
By the sounds of it, an upscaling DVD player is superior to a non-upscaler even if feed to the non-1080p chip TV...?

The processor converts SD and HD video signals from DTV
broadcasting and DVD players to 1080p without loss of image
details. It also applies progressive conversion to upgrade 1080i highdefinition
video signals to 1080p signals. This allows Viera to render
pictures that are more beautiful than the original.
==================
This is what Panasonic claim the 1080p "chip" will do.....

It could go either way and differences likely subtle. It's a good argument based on technicalities but from experience questionable as to how much real world difference it would make.
If you are really concerned about this the correct answer is get a native 1280x720 or 1920X1080.

people get paid a lot for stuff like that
the public just eats it up

Give the public a break mate, being gullible is what we do, LOL.
Now theoretically, that should mean the upscale DVD players are all hype as well, especially on a 42inch screen....?

Based on some reading I did elsewhere, it seems that the effectiveness of the
upscale part of the DVD is in doubt{DVD players costing between $100-$130US}, but newer technology and the all digital chain of HDMI-HDMI might make it worth it, ie, you can set the upscale DVD player to output @480p/567p, and let the HDTV do the upscale.

It's all about bypassing the internal scaler of the display and these days a native 480p is no longer out there. That was the realm of CRT...
There is no doubt based on imaging science. The necessity is relative though and as always related to your expectations and most importantly viewing distance.

================
This one costs about $150AUD, so I'll probably get it and fiddle with the various outputs, ie, 576p/720/1080i/p and see what the best result is.
