Finally a cheaper DVI- SDI converter

http://www.gefen.com/kvm/product.jsp?prod_id=2566

works both way, dvi to sdi and hd-sdi and sdi to dvi...

Configuration for a DVI to SDI conversion requires no more than a simple selection on the unit.

Addendum:

As of March 2005 ( i emailed their tech support )- gefen is no longer supporting dvi-sdi conversion.

This has been around for a while.
However, there is a school of thought that suggests that DVI should be kept as DVI, since most professional projectors and devices like the Vista Montage and Barco Encore can handle DVI natively.

I understand HD-SDI doesn't actually go as far as SD-SDI.

but you cant send dvi more than 12 feet without very expensive convertors.

Have you seen or tested this device?

I am yet undecided on whther DVI should stay DVI. I found this device because it could be useful sometimes to send "hd" content over a single cable.

Best wishes,

[samsc]

yes.

dvi-ramp - these have been around longer.

they are much more expensive than $2000 for the gefen box.
i called them when they first came out.

cant remember the exact cost.
possibly close to $10,000 -someone can correct me on this?

isnt distributing dvi over anything other than a short run difficult?
and the cables are not designed for long runs.

28mar2005 -they seem to have removed the dvi -sdi conversion but from their webpage.
their webpage used to indicate that you could change the direction of conversion using jumpers.
The box still appears to have a dvi-input and a dvi-output

There is some Dvi to fiber options out there..

Here is a couple:

I don't have any experince with this.

I am worried about a few of these solutions I have used in the past. I notice that the Gefen boxes tend to fail. Of course I have noticed this more with analogue than digital but I am curious if anyone has feedback on success with extender and converter boxes.

I am specifically looking for DVI over ethernet boxes and DVI to SDI converters.
Also would be nice to find a box that perhaps output multiple signal types simultaneously.

Doremi is not so expensive ( well, in the video world expensive is REALLY expensive) and have good products.

I just had some of the doremi DSDI-20s on a tour I was programming, and we were having problems with them holding settings after powering down. They evertually held, but we had lots of problems with them. Also, there is no way to genlock these, if you need that in your system, so need another box for that.

As for DVI over ehternet boxes, I am doing a show right now where we have some of the Magenta Research boxes, they work pretty well, and have thernet AND fiber outputs (intersting to note though, the ones we got did not have the fiber enabled for some reason).

One problem with most of these boxes though, is that while they use Cat 5e able, they CANNOT run on most ethernet systems. The building we are in, for instance has networking all over the place, the bandwith these use if much higher than ethernet can take (I think they use like 1.6 gbps) so in the end we needed to convert to HD-SDI, which the building has wiring for as well, and then convert back to DVI on the other end. But when I had them all hooked up at FOH before everything was in place, they worked great.
