Hi, I am thinking about buying a CS-1 to connect to my front CRT and my HDTV at the same time. I having been thinking about buying the CS-1 because of the fact that it can scale a progressive image.



Here is my question, I have a old Iscan Pro, and I was thinking about connecting the Iscan to the CS-1 using a VGA to BNC breakout cable, VGA from the Iscan output and the BNC Green, Red and Blue to the Y Pb Pr progressive input on the CS-1. Then using a second VGA to BNC breakout cable to output from the CS-1 to my HDTV. VGA end from the CS-1 and BNC Green, Red and Blue end into the Y Pb Pr input on the TV.



Would the CS-1 take the progressive output from the Iscan and scale it, and by doing so would I get a better image than standard interlace output to the CS-1??



Thanks

Zagby,



What you would be doing in this case is bypassing the de-interlacer in the CS-1. The only reason that I could see doing this is if you thought that the de-interlacer in the IScan was significantly better than the one in the CS-1. You will, however, be putting lots of additional stuff in the signal path (the iscan, and lots of connectors and cables). This typically will degrade the signal.

The Iscan and CS both use the Silicon Image de-interlacing IC, but I think the CS uses a newer one. I think you would be better off just feeding the signal directly to the CS.

Hi Ken and Matt,



Yes, I was thinking that would be the case with the added cables, and I hear that the Sil504 chipset in the CS-1 does a better job of de-interlacing that the Sil503 in the Iscan Pro. I guess the idea with the progessive input would be for connecting a DVD player to it with DCDi de-interlacing.



Always, thanks.
