I dont know but I doubt it.

This box does dvi to sdi and sdi to dvi but its $2,000 http://www.gefen.com/kvm/product.jsp?prod_id=2566

I presumed that the signal would be scan converted. I can't think of many sdi input devices which would take Catalyst RGBHV.

Extron make an sdi scanconverter all in one.
