progressive scan support ?

[paulodeleo]

DScaler is a software for using only with TV cards based on bt878 family chip. These are limited to composite and s-video input. For progressive scan we need component input. So, no way to test using this type of TV cards / DScale.

Ok, thanks for clearing that up... now I can stop thinking about it.

@dlanor: I just wanted to know if a program like DScaler could help you test progressive scan mode?

No. What we need to test is how a real progressive scan monitor responds to real progressive scan signals from the PS2, so as to gain total control of what those signals will display. That is impossible to do without a real progressive scan monitor, regardless of any software used.

I don't have a progressive scan monitor, and neither does EP, so we are unable to work on this.

It seems clear from the DScaler docs that it can make a PC with its normal monitor receive and display signals from unrelated video standards, possibly including progressive scan. But results from such a software emulation are not valid for how a real monitor will behave.

Most likely the DScaler software will produce a useful picture even for many cases where real hardware would simply lock up and/or display garbage, and while that is good for a TV viewer who wants to see a program, it is very bad (in fact worthless) for testing signal validity.

Also, DScaler itself requires a 'supported capture card', and while my Geforce FX 5900 Ultra does have VIVO connectors and has served my own capture needs well enough, it is NOT included in the compatibility list. So to use DScaler at all I would evidently have to buy special video capture hardware...

So forget about it, thÃ*s route leads nowhere, for several different reasons.

Yes, I'm aware that there was probably a good reason for needing to test this on a real progressive scan supported monitor, so I understand the need for a completely accurate testing environment. Anyway, I currently don't have any interest in seeing this feature being functional in uLE. I thought it was just worth mentioning in case there was some other advantage in knowing about it, if not then no big deal.
