NMOS Setup?

Hello - Wondering if anyone has the new Decklink IP cards and if so, have you been successful using NMOS... the web site says that the devices support it, but I can't see where one would access this capability. Feels like there is a forthcoming upgrade to the BM VideoHubs that may be required to setup / advertise available 2110 sources via NMOS...

Very curious because I can't seem to find any information in BM's product documentation...

Thanks,

Hi,

did you already receive the card? I'm still waiting for both the Decklink card and the SDI box.

The card should look fo a registry using is-04 via DNS-SD. Do you see any requests? You can also check if is-05 is working.

is-05 is using HTTP to control the devices. You can use your browser, curl or the nmos-cpp kit to do some experiments. Just have a look on the specs. Maybe try to request available API versions using is-05 (http(s)://<ip address or hostname>:<port>/x-nmos/connection/)
https://specs.amwa.tv/is-04/
https://specs.amwa.tv/is-05/

Thanks for the suggestions. I'll give them a whirl tomorrow. I did get the IP / SDI Card and I have it here, but the rest of the IP / 2110 product line from BM seems to still be on its way to resellers. The 2110 IP Converter hasn't started shipping yet, and my reseller is telling me December / January for that one. We'll know for sure when BM updates their firmware to support it. Looks like they are having some issues with the software though since it appears that the initial support for all of the IP products is only 2 2110 streams, not 3 as was initially advertised.

Thanks,

Yep, also got the information from the supplyer that there is a big firmware issue and all delivieries are stopped until further notice.

Let's see when I will the decklink card, seems like they are not held back.

Did you get any nmos info out of the card?

Hello, we have 2 HD IP Optical cards and a IP Converter. With NMOS-CPP, I get IS-04 information, in read-only mode.
I cannot change the Active flag to route a source to a destination (IS-05).
T'm working on windows with 12.7.1 driver

Hi Tobias -

Thanks for the suggestions and sorry for the slow response. I've been up to my eyeballs in production this month...

Some good news and bad news on the 2110 / BM front. First the good news is that I was able to take your suggestion and connect to the Decklink card as well as the 2110 IP Converter (I purchased a few of these which have since come in as well). Using a web browser, I'm able to connect to both just fine and discern from the information available which ports the various essences were being sent on for their 2110 output. So good news there. Also, I have a Panasonic Kairos IP switcher, and once I had the port information for the video essence in the 2110 stream, it was able to connect to the Decklink card.

Now for the bad news... while I do indeed have a PTPv2 clock on my network, it does not appear that the Decklink card and the Kairos were properly synced to it. While the Kairos could receive the 2110 stream from the Decklink card (though not the 2110 converter), it gave me an 'out of sync' error and the video stream was not frame-synced. Thus it was a garbled mess. Also, when I tried to connect the Decklink 2110 stream to the 2110 IP converter, the converter recognized the NMOS announcement and allowed me to select either stream 1 or 2 output, but alas no video came through.

Anyway, so that's my progress at this point with 2110 and the BM products. I'm sure that there is more configuration that I need to implement somewhere along the lines to get things to work properly, I'll just have to try and spend more time with it over the coming week or two and see if I can successfully get this implemented.

Thanks,

Hey Brett,

thanks for that feedback. Still waiting for my orders, but no delivery date announced...

According to Blackmagic Design their devices can act as PTPv2 grand master. You could use Meinberg's PTP Track Hound application to check PTP status of your network and what clocks are out there. On their demo setup they did not use a dedicated clock.

My card and converter arrived the other week.

I don't have a proper PTP clock, but the converter appears to be acting as the clock for both.
It is also worth noting that I don't have anything else doing 2110 or PTP on the network currently, so I can't comment on interoperability

Usually the converter is able to see the decklink and I can route signals from decklink to converter on the front panel of the converter, but sometimes it fails to see the decklink.
I haven't seen a way to choose what is being sent into the decklink other than through nmos.

I have also run https://github.com/sony/nmos-cpp to try out nmos. Once I got it deployed and running, both devices have registered themselves there, and using https://github.com/sony/nmos-js I am able to control what streams everything is subscribing to.
I think I have had it on occasion where one device doesnt manage to register with the nmos registry, I havent tried to investigate this, so that may or may not be blackmagics fault

Hi All

The Blackmagic 2110 uses PTPv2 Domain 127 with 4 Announce Messages per Second (-2)
Because it's hard coded and not ajustable, all the other devices need to set to the same values

So some good news... I was finally able to get the 2110 converter working with my Panasonic Kairos setup. In what was a bit of an interesting accident, I ended up setting up my second 2110 converter just to see if the two could transmit a signal back and forth. When I selected the originating 2110 converter's IP video stream, it 'activated' the master_enable which allowed the Kairos to see the video stream as well. However, over a period of about 10-15 minutes, the IP video signal started getting jittery, so that wasn't ideal. I'll need more time to uncover that issues, but at least for the moment I've been able to successfully transmit a 2110 signal from the BM 2110 converter to my Kairos switcher!

In regards to clocking... The Kairos was setup as a follower and it appeared to be able to successfully identify the BM 2110 converter as its clock source. I say appeared because in Kairos it showed that it was getting a sync signal from the network (and the BM 2110 was the only other device on the network, at least until I added the second one). That said, the Kairos also showed "no sync" when the IP 2110 video came up in the multi-view, so that was a bit curious. I suspect that this plays into the jitter issue that I was seeing and I suspect that the two are related.... more work to do when I have some extra time, but in general, positive developments.

BTW - for those that are interested, I'm using a Ubiquiti UniFi Pro Aggregation switch (our company network is almost all UniFi-based, except for our Peplink routers that provide PepVPN connectivity for our bonded-cellular remote productions). I also have a UniFi Enterprise XG 24 switch, the one that BM notes in the 2110 users guide as compatible, but I've not had a chance to integrate it into our network. That will probably happen next week, at which point I'll spend more time working to integrate 2110 into our environment.

Hi Brett,

I'm wondering if you've made any progress with this.... I've got a Kairos setup that is working but no luck with the blackmagic 2110 ip convertor 3x3g... we have a mellanox switch and I can see the igmp v3 multicast group with either kairos in it, or a pair of blackmagic convertors.

They (kairos and blackmagic devices) dont join the multicast group simultaneously (viewed on the switch), and I can't set one Blackmagic device to receive the stream from the other. Using Riedel nmos explorer on windows it is possible to start streams, stop them, copy the sdp, change or view parameters etc.

I'm wondering if some other necessary protocols have been set like the ptp with no option to change them...

I use a PI4 Compute Module with a TimeBeat GPS card as PTP clock in my lab environment.

I have been doing some tests with ffmpeg as receiver for 2110 from the 3x3. It does not work if I have not since the last reboot connected a stream to one of my other 3x3 units.
If I make a connection to one of my other 3x3 units it works fine even if I remove the 3x3 receiver until next reboot.
I can verify that my switch detects the multicast request but no data starts to flow.

Hello all.
I've done some progress on my lab setup.
I can now see the 2 video/audio outputs of a Optical HD on a BMD ConvertIP.
110 routing is done with Riedel NMOS Explorer.
PTP coming from a Greyware server.
Coming soon : decoding video/audio with another device (Matrox)

Hi, on my side I received both a 3x3 converter, and the decklink optical card.

I started to test the converter first, but my first concern was the no ability to set the PTP domain to the one we use ( moreover using 127 by default is far from recommended practices) . So for me it's a no go for this box right now.
I still did some checks to the NMOS API, and could see that it looks very buggy as well.

I expect the card behaving the same way at least concerning PTP domain , so I won't test it for the moment.

My exchanges with BMD support give me the feeling they don't really understand how 2110 set-ups work, and how they should comply with it instead of pushing their own vision of it.

Hi,

since this appears to be the only thread on this topic, I was wandering if you have any insights on BMs claim that

Videohub Smart Control can route sources to destinations on 2110 IP networks because it can act as an NMOS controller.

The available documentation on the Videohub Smart Control Pro does not mention any of that. Does this simply mean that there is a software update needed or am I missing something?

Thank you, cheers

Martin

[Gary Adams]

That’s a good question. NMOS in the Smart Control is not ready yet. I’m sorry I don’t have any more information than that.

Gary

I also did some experiments using two 3x3 converters only. Somehow "they see each other" without an NMOS registry. As soon as I start ne registroy fo easy-nmos, they don't offer routing via its menus aymore. However they appear in the registry. Next step is to route using Riedel NMOS explorer.

Concerning PTP: I did not involve a proper PTPv2 GM. However the 3x3 can act as a GM.

That’s a good question. NMOS in the Smart Control is not ready yet. I’m sorry I don’t have any more information than that.

Hi Gary
do you know if BM will present the products at the next "JT-NM tested" session ?

Hi,

I have just purchased the BM 2110 IP converter and have a couple of questions. Not sure this is the correct place, but there seems to be related information.

I want to use the product to test encoders with 2110 inputs and decoders with 2110 outputs. I want to use the BM to convert from my playout server that has a SDI output. I want to monitor the decoder output using a SDI monitor.

My first question is where is PTP set up? I have a GrandMaster and want to feed this multicast, into the unit. The only PTP config I see mentioned is as follows:

"Set converter as a PTP follower". Reading some comments in this forum it looks like PTP may not be fully supported, but a master-slave point to point relationship.

I think the unit should join multicast - 224.0.1.129

Also I see where the output multicast addresses are set for each of the 3 streams. I do not see where the UDP port is set up for each of the essences, video, audio, etc.

Regarding the video flow IP to SDI, where is the specific multicast set up so the BM can listen to the correct address.

Thanks in advance.

Pete

Hi Pete,
I myself am just starting to get into ST2110 (so other people please correct me if, I get anything wrong!) but I'm happy to share what I was able to find out so far from experimenting with the BMD Products (converter and decklink).

My first question is where is PTP set up? I have a GrandMaster and want to feed this multicast, into the unit. The only PTP config I see mentioned is as follows:

The ST2110 Converter doesn't offer any proper PTP Settings except for the checkbox that sets it into slave only mode. However after looking at the ptp packets in wireshark I figured out that the ST2110 converter is set up on ptpt domain 127 and comes with an internal Grandmaster clock that has a very low priority (high number). So basically as soon as you connect a proper PTP time server to the network it should immediately take over the role of the grandmaster clock, making the BM converter an ordinary clock again.

Also I see where the output multicast addresses are set for each of the 3 streams. I do not see where the UDP port is set up for each of the essences, video, audio, etc.

Regarding the video flow IP to SDI, where is the specific multicast set up so the BM can listen to the correct address.

The routing of the video signals has to be done via nmos. The ST2110 converter offers a really basic implementation of an nmos registry/ controller but I'd recommend looking into easy nmos. Once you have set up a proper nmmos registry, a control software like Riedel nmos explorer will also let you configure the separate multicast addresses + ports for video, audio and ancillary streams.

Hope this helps
Max

Max,

Many thanks for your reply. I have been doing some more experimentation regarding this unit.

I think I get the PTP set up as I have been monitoring via Wireshark also. When the PTP follower option is unchecked, I see the BM converter act as a Grand Master, though in the ANNOUCE message, it states the Timesource is an INTERNAL OSCILLATOR.

When the BM converter is connected to my GPS sourced Grand Master and the PTP Follower is checked, I do not see any response from the BM. I have a PC also on the network that is taking my same GM, I see a periodic DELAY_REQ message from my PC. I do not see this from the BM converter, so I do not know that the BM is connected to my GM.

I have a valid SDI source connected to SDI 1. I can monitor this on the BM converter screen. However when I monitor the BM multicast output that is directly connected to my laptop via 10G Ethernet interface, I see the PTP info incoming but not the 2110 multicast for the address set up in the BM for SDI 1. DO you know what I am missing?

Regards

Pete

Hi Pete,
no worries.

Your setup seems to be really close to the one I have.
Your are right, the BM Converter should respond with a delay request just like your PC does. I would assume that the issue lies within the configuration of your Grand Master Clock. Did you check if the announce messages coming from your GMC have the same PTP domain as the ones that were coming from the BMD converter (127)?

I have a valid SDI source connected to SDI 1. I can monitor this on the BM converter screen. However when I monitor the BM multicast output that is directly connected to my laptop via 10G Ethernet interface, I see the PTP info incoming but not the 2110 multicast for the address set up in the BM for SDI 1. DO you know what I am missing?

Monitoring the st2110 output with a point to point connection to your laptop doesn't work because the BM converter doesnt just constantly emit a video stream on its network interface. The sender has to be specifically activated through nmos for it to start the stream. This can be done via easy nmos.

Hope this helps
Max

has anyone had any luck with making two of the 2110 convertors stream to each other?

in my case via an nvidia mellanox switch (setup as a central part of a working 2110 system) it seems that i can't stream from one unit to another.

using the riedel nmos explorer i can configure streams on the two convertors and start/stop the streams...

i'd be interested to hear from anyone that has successfully sent video between two 2110 convertors, and see if i can replicate it...

I have tried to send a signal between two 2110 convertor units with a different switch and they still dont seem to work.

i'm guessing that they dont work and thats that? or has anyone successfully used these?

I had a setup of two of those running without an extra PTP master clock and NMOS registry. They will show up in each others menu where you can route and start the streams.
Used an Arista 7050SX-64.

Tobias,

I have a similar setup to you, Arista 7050SX3 switch but I do have a PTP master and NMOS registry. I have a pair of BMD 2110 converters attached to the switch. Using Reidel NMOS explorer I can see the devices, sender and receivers. I can successfully route the 2110 output of either BMD 2110 to a 3rd party 2110 receiver and get video. When I look at the igmp group table I can see the entry created by the 3rd party 2110 receiver subscribing to the multicast group.

If I try and route any streams TO one of the BMD 2110 receivers everything looks good in NMOS explorer but I don't get a video output (which seems consistent with what a number of others are experiencing). If I look at the igmp group table on the switch, no group has been created suggesting the BMD 2110 receiver has not subscribed to the multicast group. I have also tried a tcpdump of the igmp traffic on the port the BMD 2110 receiver is using and as far as I can tell it is not sending igmp joins when streams are routed by NMOS explorer. It is however responding to the periodic igmp membership queries but it is not listing the expected multicast group in the reply.

I can successfully loop back its own 2110 traffic and get video out which would again suggest everything is OK on the NMOS side, but that the issue is that the multicast traffic is not being forwarded to the BMD 2110 receiver port because of the missing igmp signalling.

I'm wondering if you had to do anything on your Arista to get your set up to work that I might be missing?

But it is absolutely important and not really the question. Changing the PTP domain is an essential feature that every 2210 device must support. Without that, we don't even need to talk about whether the cards are really usable.

I believe I had similar issues with the multicast on a different switch. it does seem these hardware 2110 convertors do not work. i wonder if blackmagic will admit that and offer refunds? i feel i have wasted enough time on these... do not buy is my advice to anyone considering it...

I will check igmp again. I remember that sometimes there was no join and sometimes there was. But I don't remeber what I changed to get it to do a proper join.

Yes, I have successfully sent 2110 streams between two BM IP 2110 converters as well as between the converters and a DeckLink IP 2110 card. We have a UniFi Enterprise XG switch. Additionally, I have been able to send video from the BM IP 2110 to a Panasonic KAIROS. I've done this by manually looking up the config information via a web browser and making x-noms queries with the BM devices to get the info as well as using Riedel's NMOS Explorer. I've literally had video running into the KAIROS through via IP 2110 streams for 24 hours a day for the past 5 days without any issue that I can see... however, within KAIROS the video stream shows as "no sync", likely the result of a timing issue between how BM is managing PTP timing vs the 2110 standard.

All that being said, what I have NOT been able to do successfully yet is transmit 2110 flows out of KAIROS into BM IP 2110 converters, even using the NMOS Explorer. I did have it going for a brief period, but I had to rebooted my KAIROS and it hasn't worked since.

Sorry for the intermittent posts... I've been slammed with production and have had very little time to get back to 2110-land.

Hi Brett,

I'm wondering if you've made any progress with this.... I've got a Kairos setup that is working but no luck with the blackmagic 2110 ip convertor 3x3g... we have a mellanox switch and I can see the igmp v3 multicast group with either kairos in it, or a pair of blackmagic convertors.

They (kairos and blackmagic devices) dont join the multicast group simultaneously (viewed on the switch), and I can't set one Blackmagic device to receive the stream from the other. Using Riedel nmos explorer on windows it is possible to start streams, stop them, copy the sdp, change or view parameters etc.

I'm wondering if some other necessary protocols have been set like the ptp with no option to change them...

I'm not aware of any... in KAIROS, to receive a stream I have been successful using NMOS Explorer, but I've also hand-configured the multicast address, port, and source IP address... I've used a web browser and x-nmos commands to get the port number for the video flow (and audio flow for that matter) directly from the BM devices.

That said, when I've done it manually, I had to use my other BM IP 2110 converter to start the stream and then configure KAIROS to join it... I've not been able to get KAIROS itself to connect with the IP 2110 converter and start the stream.

SUCCESS!!

Spent some time this evening working with a colleague to reconfigure my network and re-tested IP 2110 transmission between 4 BM IP 2110 converters and a Panasonic KAIROS switcher and I can confirm that we have successfully transmitted AND received video between and among the devices.

So, a few notes on what we're using:

Network: UniFi
Switch: UniFi Enterprise XG
DAC: GTek 100G to 4x 25G
All 2110 Traffic segmented on one VLAN

Stream Routing / Subscriptions: HP PC running Riedel NMOS Explorer
Converters: 4x BM IP 2110 Converters
Switcher: Panasonic KAIROS running firmware 1.6.2 (latest... just released a few days ago)

What we're sending: 6 IP 2110 output streams from the KAIROS to the BM IP 2110 converters and 4 streams from the IP 2110 converters into KAIROS (please note that we are currently only working with video streams... we've not tested audio yet).

How we're doing it: We're using NMOS Explorer to initiate all starting / stopping of streams. For example, when sending a KAIROS stream to a BM converter, within NMOS Explorer we would first use the software to start the stream on KAIROS, then we would stop the stream receiver on the BM IP 2110 converter (if it thought there was an active stream) then we would drag / drop the KAIROS sender stream onto the BM IP 2110 receiver and voila, IP 2110 video stream being sent from KAIROS to the IP converters!

So in short, I can say that we have been able to successfully get 2110 video back and forth between these devices... that being said, from time to time KAIROS shows the video inputs as "out of sync", and again, we've not doing anything with audio yet, but we at least have video going back and forth at the moment... I'm currently running this 6 out 4 in configuration overnight just to see how the system reacts under load for some time.

Hi Brett,

do you have the NMOS licence for Kairos?

Kairos hasnt shown up in Riedel NMOS explorer at any stage for but we dont have the nmos licence.... we're using KairosCreator primarily...

Yes, we have the NMOS license for KAIROS. It shows up just fine in NMOS Explorer.

Hello Guys,

Sorry, I jumped in on this topic since I would like to setup this DeckLink IP HD Optical card in my IP LAB.

I read the thread and was surprised about that I cannot set the PTP domain from 127 standard, and as I see this is still a valid point. Did you guys somehow was able to adjust it? My PTP domain is 1 ... This looks ridiculous not to be able to set the domain.

Anyhow, I was not able to succeed in registering my device to the NMOS registry, this is the first problem.
It is also interesting that I cannot set the NMOS registration URL manually, but OK, I quickly set up DNS-SD service, which perfectly works for all devices like GrassValley LDX-100, IPVU PhabrixQXL, etc.
This card does not do anything...

I captured the packets with WireShark from the DeckLink card and I realized it just tried to query mDNS protocol instead of DNS-SD, there is no single try from this device to the DNS server...
Is there any way to force it to use DNS-SD instead of mDNS since the brochure says that this is capable of doing it...?

Much appreciated for all your help,
Gergely

Hello Guys,

Sorry, I jumped in on this topic since I would like to setup this DeckLink IP HD Optical card in my IP LAB.

Was casually browsing all the 2110 products Blackmagic has upcoming and saw a nice screenshot that hints at them giving us the possibility to change the PTP Domain in a future update!
Almost at the bottom of the product page for the new SmartView 4K G3 you will find the screenshot mentioned attached to the section "Remote Control - Software for Mac and Windows". I am at the moment not allowed to post links in this forum.

That’s a good question. NMOS in the Smart Control is not ready yet. I’m sorry I don’t have any more information than that.

Hi Gary, Any update on this?

Also, if this feature is still in the pipeline it would be great if Smart Control could expose the Videohub protocol to allow NMOS routing to be easily controlled from 3rd party systems.

Hello Roddy. We do not have information on when the updates will happen. I will pass along your suggestion.

Hi Brett / smpte 2110 folks,

In case of of this is useful to anyone else here's my latest update....

with the current Blackmagic Convertors software (Blackmagic Converters 10.2 Update) I've been able to stream to Kairos from the Blackmagic 2110 IP Converter 3x3G...

I started by streaming between two of the 2110 IP Converter 3x3G devices. Once I had that working I reconnected via a switch also connected to Kairos (the 2nd 2110 IP Converter 3x3G is starting the stream, if its not on the network set to receive the stream then Kairos gets no data).

One point I observed is that the convertors don't stream if they are not displaying a 10g connection and they seem particular about cables to achieve the 10g connection.

Once those streams were running I was able to copy the multicast address and port setting into Kairos and I have 3 x 1080p input streams running with sync (the new firmware allows ptp domain to be set). They seem to be solid and the streams resume after a power outage. The 2nd 2110 IP Converter 3x3G device is also subscribed to the same streams...

I have had no success sending a stream from Kairos to Blackmagic... the Blackmagic software doesnt see the stream (the other Blackmagic devices streams are available in a dropdown)... It looks like it might be possible to manually load an sdp file into the convertors software but I haven't successfully created one that works... (it would be interesting to see a working sdp file streaming from Kairos to Blakcmagic if anyone has one)...

It seems like the Riedel NMOS explorer may not work with current firmware. I cant start and stop streams without errors and the stream info in the riedel software (1.13.221) doesnt match the blackmagic setup.

SUCCESS!!

Spent some time this evening working with a colleague to reconfigure my network and re-tested IP 2110 transmission between 4 BM IP 2110 converters and a Panasonic KAIROS switcher and I can confirm that we have successfully transmitted AND received video between and among the devices.

So, a few notes on what we're using:

Network: UniFi
Switch: UniFi Enterprise XG
DAC: GTek 100G to 4x 25G
All 2110 Traffic segmented on one VLAN

Stream Routing / Subscriptions: HP PC running Riedel NMOS Explorer
Converters: 4x BM IP 2110 Converters
Switcher: Panasonic KAIROS running firmware 1.6.2 (latest... just released a few days ago)

What we're sending: 6 IP 2110 output streams from the KAIROS to the BM IP 2110 converters and 4 streams from the IP 2110 converters into KAIROS (please note that we are currently only working with video streams... we've not tested audio yet).

How we're doing it: We're using NMOS Explorer to initiate all starting / stopping of streams. For example, when sending a KAIROS stream to a BM converter, within NMOS Explorer we would first use the software to start the stream on KAIROS, then we would stop the stream receiver on the BM IP 2110 converter (if it thought there was an active stream) then we would drag / drop the KAIROS sender stream onto the BM IP 2110 receiver and voila, IP 2110 video stream being sent from KAIROS to the IP converters!

So in short, I can say that we have been able to successfully get 2110 video back and forth between these devices... that being said, from time to time KAIROS shows the video inputs as "out of sync", and again, we've not doing anything with audio yet, but we at least have video going back and forth at the moment... I'm currently running this 6 out 4 in configuration overnight just to see how the system reacts under load for some time.

Hello everyone, I'm trying to get a NMOS setup running but have hit a bit of a wall.

Here are the specs:

Video Source: Canon CR-N300
Sending Converter: BM 2110 IP Mini BiDirect 12G
Receiving Converter: BM 2110 IP Mini BiDirect 12G
Router: Netgear GS308Ev4
Switcher: BM ATEM 2 M/E Constellation HD
NMOS: Riedel NMOS Explorer
OS: Windows 11 (I have access to a Mac with an M2 chip)

I have IGMP Snooping turned on, the sending receiver is the PTP clock, the receiver is set as follower. I have the converters set to auto config the multicast address and NMOS registry.

I can see and route in NMOS Explorer but I am not getting any video output. I did test out the converters PTP and got video. From what I understand from the documentation I've been following I should have everything configured correctly but no dice. Any recommendations?

You have to activate the streams manually, this can be done in easy-nmos, if you are using this for the registry etc. If you have no registry setup, then route the signals using the dispaly menus on the devices itself.
