It's not necessary for the source signal to be 1080p. It's very easy for a high end scaler (i.e. Faroudja 5000) to deinterlace 1080i and output a 1080p picture out of this world (similar to how a progressive DVD player outputs 480p). The question is, how well can this new box do it? Can it come anywhere close to the 5000? Faroudja's propietary deinterlacing and scaling algorithms are the state of the art, that's why a 5000 costs 25k.
1080p has a retrace time spec that very few display devices can meet. As far as I know only a few 9" CRT FPTVs are capable of handling a 1080p signal, not to mention capable of fully displaying it: Sony G90; Electrohome 9500 (and Vidikron Vision One clone); Barco 1209s (and Runco clone).
Unfortunately, the article doesn't mention anything about doing an inverse telecine process on 1080i signals. That would be the perfect feature. Then all these HD movies broadcast in 1080i could be output as 1080p, with no funny interpolation algorithms, just a straight recovery of the original film frames (in the digital domain, just like the best progressive DVD players).
