If it's analog, what is the use (except for broadcasters and editing studios) of converting to HD SDI?
There's no particular advantage in converting analog to HD-SDI that I know of, except that this ability allows me to use Gefen's HD-SDI to DVI Scaler with Gennum VXP processing. This piece has only two HD-SDI inputs and no RGB, component, DVI or HDMI inputs. None of my sources include an HD-SDI output (or SDI as of yet). I did locate one such device, the AJA HD10A A/D Converter, which appears to do what I want, but it's list price is $890 - not what I'm looking for. I would prefer something priced roughly half of that.
Maybe this isn't worth pursuing - I have no idea. It's just a thought. I'd rather that Gefen make a special version of their Home Theater Scaler that included Gennum VXP processing. Or, failing that, add an analog input of some kind to their HD-SDI to DVI scaler.
