After all this discussion regarding 1080i-->1080p on this board, I have a couple of questions:
1) Why did the Powers That Be even *decide* to do 1080i as one of the two high-def resolutions, and why aren't more broadcasters (i.e., any except ABC) choosing 720p instead? It seems that with all the problems with 480i-->480p conversion, that a "p" resolution would have been selected for HD (or only progressive resolutions, and no i resolutions). I understand that CRT technology is still somewhat prevelant (although how much for HD sets is debateable), but inasmuch as a lot of these CRT's can do 480p, surely they could also just easily as do 1080p?
2) With respect to 1080i->1080p, it seems to me that all the algorithms that have been "tried and true" with 480i->480p (Faroudja's DCDi, Silicon Image's, etc.), it wouldn't be very difficult to implement the same algs with 1080i->1080p, and just boost the horsepower to compensate for the increased resolution? Is this the case? If not, why not? I would presume that with the advent of faster processing capabilities, it wouldn't be hard to do 1080i->1080p these days. But, it seems that only the ancient F5000 and the new KD HD Leeza do the trick . . . . .
