Does anybody know whether Pixel Plus 2 will improve a Hi-Def picture even more?
As it stands, we don't know for sure! They are bringing out a new "Pixel Plus 2 HD" for the next range of TVs, so we assume it will have an effect on the picture - but we'll have to wait for first reviews of that system in a few months. Regarding feeding an HD picture into a current Pixel Plus 2 set, then that would depend on the definition you are feeding it. Pixel Plus 2, I believe, works at a reduced power via DVI at 1080i and is disabled at 720p. It will probably come down to personal taste!
Pixel plus 2 makes a high-def picture look worse rather than better: it downscales it to standard-definition (losing much of the information in the picture irrevocably) then converts it from digital to analogue, then back to digital again, then applies pixel plus and, as a part of that, scales it back up to the resolution of the screen.
Basically it makes HD look like SD.
By contrast, the forthcoming pixel plus 2 HD system may well make HD look better.
Also, Pixel Plus HD maintains all processing in the digital domain, eliminating the analogue stage (which, IMHO, Philips should have done with PP2).
Personally, I'm not a big fan of all these interpolating and NR technologies that the manufacturers seem to be obsessed with. I'd much rather they spend the R&D dollars on perfecting their screens and internal scalers, perhaps even properly calibrating them prior to market???
You may not be a big fan of the likes of PP2, but it doesn't half work! With the dire quality of signals that these poor LCD's are having to cope with, the better the panel, the worse the picture could look! We need all the processing we can get to help these screens present something watchable, especially in the analogue domain.
When we start recieving decent digital HD signals then the PP2HD will come into play, but quite what it's going to do to a HiDef broadcast to improve it is hard to imagine!
No, it's got to be a combination of panel improvement and processing improvement (analogue and digital)
