Integrating a Gefen EXT-HD-DSMP Digital signage player with TVS

We're using this media player in a church to loop content when there isn't a service and to auto-start a countdown timer before services.  It has an HDMI output that Gefen says can either output in "NTSC1080p" or "NTSC1080i" but all we seem to be getting out of it is 1080p30 from either setting.  Obviously the ATEM TVS needs it at 1080p 59.97 and we have to figure out what sort of scaling/framerate conversion we can do here.

An obvious option would be a Decimator, but random little boxes with "wall wart" power plugs laying around isn't optimal for a studio installation.  Gefen makes an inexpensive wall mounted scaler box, but it isn't listed in the compatible equipment guide.  Blackmagic makes some interesting mini converters, but simply taking this to SDI won't seem to solve the framerate issue.

Any of you ot there doing signal conversions like this without having to try out a dozen different devices?  Thanks for any help you can provide!

If you have an atem tvs it's

If you have an atem tvs it's 1080i, it doesn't do 1080p. So try the player at 1080i if that doesn't work it might be a hdcp issue..

Already tried, perhaps not

Already tried, perhaps not too surprisingly the ATEM doesn't like either the NTSC1080i or the NTSC1080p settings.  When I set to the NTSC1090i setting, my Atomos Ninja reports it's getting 1080p30.

Guess I shouldn't be surprised that a DSP isn't all that concerned about what output it actually gives, since a TV is going to pretty much take whatever it gets.

Hence the need to put in some sort of signal converter.

Connect the player to the TV

Connect the player to the TV and adjust settings until the TV advises it's 1080i 60 or 1080 59.97. pressing the TV's  info button on its remote should resolve the set resolution of the box. Unlike the newer atems the TVS is quite flexible between 60 - 59.97.

If you've got the money, use

If you've got the money, use a Teranex 2D ( or perhaps the newer cheaper model), put it in your rack. Monitor over the network, even add as a rentrant device to your matrix(videohub), it's "the Studio" way to do it.

Maybe I'm not being clear

Maybe I'm not being clear here.  It's only outputting 30p.  

What equipment, whether it be an HDMi->SDI converter, or HDMI->HDMI scaler are folks using with good results with an ATEM?

Decorator. Just get over the

Decorator.
Just get over the fact it's not a pretty rack mount piece of gear.
It's the right tool, and you already know from searching.
If you say I want a scaler but not decimator, then it is hard to help you.

But you could use Kramer 435

Weird you would think that...

Not sure why you would think that mate.

Most people here wouldn't care about form factor, they are looking for cost effective solutions to problems, and hence the decimator and datavideo suggestions which provide perfect & very flexible solutions to your exact problem, and a problem many others have faced in the past.

Was why I posted how I, and many "studio installations" I have worked with, convert from low-speed 1080p or computers or other devices not capable of 50Hz / 59.94Hz (except in PsF) to 1080i. 

What I think you are really asking is

  • Is there a device that converts from 1080p at 1.5Gb/s speeds to PsF such that it's compatible with 1080i devices for less than the cost of a data video or decimator that is also in rack mount form factor with an internal power-supply?

And to answer that, the answer is no!

As Hatzenbach just mentioned the Decimator is the widely-accepted "best solution" that many people here use, and cable ties can help with organising mini-convertors.

Thanks guys.  I figured there

Thanks guys.  I figured there might be a different way than going the decimator route, but apparently that's going to be the best way.  At least this is confirmation that my first inclination was going to be the solution I'd have to do with, and it's going to be a pretty handy thing to have on-hand, anyways.

Now if those folks would just make the unit rack mountable, with a regular power cord, I'd have never even bothered to ask...
