It has nothing to do with cleaning up a signal. In fact the disk should already be "cleaned up" as you put it, we're not talking about an analog source, or an analog output or even an analog television. Sending the exact signal would be ideal.
The issue is that the new "next gen" dvd formats support overlays. So what happens is that things like menus, chapters, timelines, picture in picture needs to be rendered on top of the movie and then shown on the TV. The processing which occurs to add these elements to the signal is occuring on an interlaced picture (the components to do it on a 1080p24 signal are still too expensive (I suppose). Therefore they need a chip like this to convert the updated picture from the modified 1080i60 into the 1080p60 output.
It is unfortunate that typically all you want to do is just watch the movie which would be a straight transfer, but they do need to support all of the advanced features.
Well now I am totally confused. I thought all content was stored on HD-DVD's and Blu-Ray discs as 1080/24p and that this content could be sent to a display as 1080/24p if the player supported it (which some apparently do) and that if you had a 2Hz display there was no interlacing and de-interlacing or HD telecining or reverse telecining because the display would then just show each 1080p/24 frame 3 times (and therefore no cadence judder would occur). But, what you are now saying is that the timelines, chapters etc are rendered only on top of 1080i/60 content, so the player has to convert it first? Does this not mean that there is no point in having 1080p/24 output as that signal must be interlaced to a 1080i/60 signal and then converted to a 1080p/60 signal in the player? And does this not also mean that the even if the display is 72Hz we are going to have to rely on whatever substandard video processing the display has to remove the cadence judder?
I've spent a few months researching all the issue related to the optimium player/display combination and am now dismayed to hear I can't feed a 1080p/24 signal to a display.
“The other one is a biggie, and it's something very noticeable in the videos: touch sensitivity is pretty bad. Using the virtual keyboard proved to be far too painful, and we're pretty sure it wasn't multitouch-friendly.”

Please enlighten me and everyone else! Thanks.
