Hardware NDI

PostTue Jun 12, 2018 3:52 pm

I want to get NDI into my Atem Switcher. What is everyones cheapest ways. I dont want to have multiple laptops. I really want a cheap decoder box.

There are a couple of NDI hardware encoder boxes (Newtek Connect Spark and BirdDog Studio), but I'm not sure there are any hardware NDI decoders out there yet.

There was some discussion on the VMix forums about using an Android media player box for this purpose, but evidently the NDI SDK does not support NDI decoding on ARM processors, it is only supported on x86:

But you could probably use something like an Intel NUC or other small form factor PC with an x86 processor and HDMI output for this purpose. There are also some Intel Atom-based media players that have Ethernet jacks and HDMI outputs available for $150 or so. I'm not sure if these are powerful enough for NDI decoding though. The Intel NUC line has versions with Core i3, i5, and i7 processors that I'm sure could do the job (although they are a bit larger and more expensive than the Atom-based units).

If you are looking for a more off-the-shelf solution, DVEO sells a few small NDI decoder boxes. The Mini D-Streamer NDI which is basically a small form factor computer with an Intel Celeron processor should work:

Well cheap and NDI doesn't go well together.. Newtek charges a steap amount of money for there NDI transmit licenses..
While the SDK is free.. The moment you want to distribute it you walk into a license thing that you need to pay for every used NDI setup.. ;)

With utmost respect to Xtreemtec, Its probably appropriate to correct misinformation, in the interest of providing accurate answers to Phil's original question.

There is *no* license fee to use NDI for any product, from any vendor. You don't pay a penny to distribute it.
Some NDI based products are commercial and there are many *free* ones too. In both cases you are not paying for NDI at all.

Integrating ATEM with NDI IP Video sources, can be done very inexpensively and really adds huge flexibility to your ATEM switcher workflows.

NDI Transmit is no longer really a product, since its functionality now comes *free* with NDI 3.5. In any case its not the tool you would use to get from NDI into an ATEM. For that you would either use NewTek Connect (there is a 2 channel *free* version) with a BMD card, or NDI Studio Monitor (*free) to go via HDMI.

FREE Newtek Connect: http://39a80d0ea5e9de8065d9-bfe57ec74076e9cb0c74346d8bd35c21.r97.cf1.rackcdn.com/NewTek%20Connect.exe
FREE Newtek NDI Studio Monitor: https://www.newtek.com/ndi/tools/

There are also low cost products on Mac such as NDI Outlet ($50) and NDI Outlet Multi (currently $99 on special) which work with BMD interfaces. http://www.sienna-tv.com/ndi/ndi-outlet.html and http://www.sienna-tv.com/ndi/ndi-outlet-multi.html

There are new products appearing for Ubuntu, such as NDI Source Multi which uses BMD cards to ingest SDI to NDI (up to 16 channels on one machine). There will also soon be NDI Outlet Multi for Ubuntu. These professional products are not expensive. http://sienna.tv/ndi
There is a forum entry with more info here https://forum.blackmagicdesign.com/viewtopic.php?f=14&t=75248

There are now hundreds of NDI based products, and I am certain there are other options to get stuff into your ATEM, including various proprietary hardware boxes. You can take a look at a fairly comprehensive list here: https://en.wikipedia.org/wiki/Network_Device_Interface

GallerySienna is absolutely correct.

Now, Newtek DOES have some products to purchase that help converting sources from capture cards in to NDI feeds, as well NDI back to "physical" feeds on output cards. But even those have free and Pro versions.

What the OP is really asking is if there is an inexpensive turnkey NDI-to-SDI solution. At this time the answer is no. BirdDog's product does seem to have some decode option now in their latest firmware update (don't quote me on that).

Sienna might be able to chime in again on this... I suppose a single desktop with multiple output cards and a Pro version of NDI Connect might get you what you need. I think NDI Connect Pro supports up to 4 NDI connections, but I don't know the full limitations: https://www.newtek.com/connect/connect-pro/

I'm not sure where the idea of licensing costs for transmitting came from...

I'm with Phil. An "appliance" that has network in, and BNC/SDI outputs would be a great device to transition traditional setups into the NDI world. Until BM adds native NDI capability (i'm betting years if ever...) i think this would be a fabulous device to have.

Wow. I would advise that the above assertion be edited by its author so that people aren't confused into thinking that NDI (which is NewTek, Inc.'s open source A/V networking protocol) will cost them and that, dearly, as was erroneously implicated above.

Looks like birddog recently posted on their social media and other Facebook streaming groups their product now outputs an NDI source as SDI HDMI making it a dual setup device adding to its ability to output NDI whilst capturing a SDI HDMI feed.

Lets clear up a few things.

NDI in software is free. Free to get access to, free to develop for, free to distribute in your own software. You do have to sign up to become a NDI developer, there is no cost.

NDI is not 'open source' (you can't have or modify the source code), but it is 'open' (it is available to anyone, even to competitors of NewTek).

I say 'in software', because that is what NDI was originally designed to be, a software based IP production format. Anything that is running on a computer with sufficient resources (Windows, Mac, Linux) can have NDI support added to it. This is different that pretty much every other IP production format that is designed to be implemented in hardware, having it run in software is *very* difficult.

NDI can be designed in hardware. That is what BirdDog and soon NewTek will have with the Connect Spark Pro product. Currently, these products are encoding. Both of these solutions are NDI in hardware.

BirdDog is working on decoding firmware, hopefully to be released soon (maybe in the next month?)

There is also a variant of NDI called, NDI|HX which is available in some products today like PTZ cameras and the current line of Spark products. These devices are encode only and the signal can be decoded on any NDI aware application.

Currently if you need to decode, there is NDI Connect and Connect Pro along with solutions from other companies, like Sienna's OSX based tools 'NDI Outlet', that allow you to take NDI and turn it back into SDI/HDMI using cards from companies like BlackMagic.
