Prog Scan on PAL via HTPC?

Excuse my ignorance but is Progressive Scan available on R2 PAL via HTPC? as its not going through a Dedicated Player?

Spectre, Others, could you clarify? If so this would be another advantage of the HTPC?

Hmm would imagine its easy enough to deinterlace and scale up as long as the correct field relationship was maintained. Don't know enough about the flagging and default 625/50 handling modes on given players though. Then display in multiples of 25fps at say 75Hz.

There isn't really anything stopping you though it will still be playing at 4% faster than the original material just like normal 625/50 (shifting the sound back to 24fps would be very problematic I'd imagine)

There is no problem in having a 'PAL' progressive output from anything other than a DVD player - so doing it with an HTPC is no problem.

Equally the DVDO Iscan Pro, Faroudja 3000U and (my) S&W Interpolator Gold all can output 576P (i.e. de-interlaced PAL from R2 discs) - I'm sure there are others, but I know these definately do output 576P!

So even though many of the new progressive scan players use either the Sil503 or Sage/Faroudja chips as used in the DVDO and Faroudja's above, they have to have the PAL progressive capability disabled.

I'd be interested to know if there was a hardware link or handset hack that 'unlocked' PAL progressive on these DVD players?

Hope this helps!

Many thanks. Yes it does in fact help alot. HTPC is now definitely the way to go.

If you want to find out more about de-interlacing, then I recommend the following document: http://www.hometheaterhifi.com/volum...e-10-2000.html

The section entitled "What can go wrong" is particularly enlightening (many of them are due to flags being set incorrectly on the disk).

Indeed :-). Sounds like a good option for an engineering menu...

Don't you remember we watched some R2 titles inbetween the R1 titles - all through the projector without having to change a thing?
All progressive scan.

HC Dude, now I'm really embarassed. Of course we did. I think it was the euphoria of the sheer quality of your demo (or the coffee) that made me forget.

Now all I've got to do is find a VGA to Barco adapter/box/lead.

You should be able to use a standard HD15-5 BNC lead for this. If you have trouble then let me know and I'll get you a price.
