Using existing LAN for 2110 IP

Hello everyone,
I work in a multi-storey building and would like to transfer the signals from three Blackmagic Studio Camera 4K Pro from the first floor to the 2nd floor. Fortunately, the whole building is networked with network cables.

My question now is: What hardware do we need to connect the cameras to our Blackmagic Television Studio HD8 ISO?
The Blackmagic Ethernet Switch 360P seems to be necessary in any case, is that correct? A DHCP server would still be useful, right?

Do we need any other important network components. A network connection between the Blackmagic Studio Camera and the Blackmagic Television Studio HD8 ISO worked, but only via a direct cable connection.

Thank you for your support!

You'll potentially be able to use the existing LAN Ethernet cabling (though 10Gbs Ethernet on cable has distance limits) - but you'll likely need to patch it physically into its own network using PTP-aware switches - like BMD's, and potentially a router (or switch capable of basic routing) if you want to bridge to other networks - I suspect (rather than just using the existing LAN switches and routers). A DHCP server on this new network would definitely be useful.

It sounds like you're probably using the built in RTMP streaming between the Studio Camera's and HD8 - this uses relatively little bandwidth and should work over pretty much any network, but introduces a lot of latency - and there's no guarantee that your cameras will all arrive in sync on the HD8 - which would be a showstopper for most uses.

The Blackmagic Ethernet Switch and associated video over IP devices are for the 2110 setup, which is different. You'd get everything in sync, and in much higher quality, but you will need a network with a significant amount of bandwidth available. There's no word yet on if the HD8 will support this internally yet, but there was an announcement that an update to the Studio Camera's will add it at some point in the future.

Finally, there is another video over IP format that the Studio Camera's can use, which again is low latency and uses a lot of network bandwidth, but this is designed to only work on a point-to-point basis between the camera and studio converter. You would connect to the HD8 using SDI connections rather than directly using the network ports.

In your position, I would be wanting to establish exactly what sort of networking is available between the locations - how many cables, is there any other equipment in between?

Thank you for your feedback!

I mentioned the failed connection between the HD8 ISO and the Studio cameras to give an example what did not work in the past via the existing network. That's why IP 2110 is especially interesting for us.

Is there a (software based) way to check our existing network for all requirements for a 2110 IP workflow before we invest and fail?
Those Blackmagic devices would be in their own virtual LAN with existing routing.

You are unlikely to be able to run 2110 over an existing office/corporate VLAN set-up - hence my post suggesting you may be able to use existing cabling with new switches and routers. If you don't have spare cabling - then you may need to re-think.

2110 requires switches etc. to be PTP-aware - which most standard office stuff won't be.

NB this is why BlackMagic sells a new switch - as it IS PTP-aware. PTP is the timing standard used to keep the audio and video streams in 2110 in-sync with each other.

If your network infrastructure IS 2110 compatible then you'll need to ensure you have enough bandwidth. Each 1080p50/60 signal needs around 2-3Gbs (50 requires less than 60) - which is how BMD gets 3 x 1080p streams into a 10Gbs Ethernet connection.

You won't be doing this with regular gigabit ethernet connectivity.

Thanks, that means, that EVERY part of the network needs to be PTP/IP2110 compatible? Adding just that one switch to add a clockmaster is not enough, correct?

And one additional not so Blackmagic question regarding this special case:
What do you think about NDI?

My understanding is that you need PTP-aware switches for 2110 video (You can sometimes squeak by with less compatible switches for AES67 audio I believe - but you're pushing your luck).

And one additional not so Blackmagic question regarding this special case:
What do you think about NDI?

NDI is a proprietary codec and comes in lots of flavours (some aimed at LANs, some aimed at WANs etc.).

It's a lower quality, compressed, approach than ST.2110 (which is usually uncompressed - so the same quality as 3G-SDI) at 1080p level - and ties you in to certain vendors (like Viz/Newtek for switchers unless you use NDI/3G-SDI conversion etc.).

I've seen some horrific motion mangling in NDI installs, and awful audio sync issues - but I think that's been where people have used software conversion between formats etc.

I'm sure with the right combination of equipment you can get OK results with NDI - and it's a budget-friendly approach. But you can also go very wrong.

Everybody starts about 2110 IP.. But these cameras while having a 10Gbit network connector. Dont do ST2110 Check the website, check the specs.. They are not 2110.. It is an IP streaming protocol. And towards the ISO8 it is streaming video. The Ethernet ports on the back of the ISO8 is just a network switch with max 1Gbit/s ports. Meaning those cameras have been doing RTMP streaming to the ISO8. With latency.

Something most normal networks should be handling perfectly fine without ANY special things..

I don't think anyone is suggesting you can connect to the HD8ISO using ST.2110 directly - that will just be SRT-protected, or straight RTMP, h.264 or h.265 LongGOP with the latency that LongGOP compression and SRT protection adds. (Probably 4:2:0 rather than 4:2:2 too...) As you rightly say the HD8ISO doesn't have 10GbE connectivity - nor has there been any discussion that it can run ST.2110.

The OP was asking about using ST.2110 to move video between different parts of their building using existing network connectivity. They were asking what hardware was needed to connect to their HD8ISO - I don't think they assumed they'd get connectivity via the Ethernet ports on their HD8 - rather that they wanted to know if they could send ST.2110 between adaptors over an existing network using a VLAN.

Some of the newer BMD Studio 4K Pro G2 and 6K Pro cameras have 10Gbs Ethernet connectivity and I think there was some discussion about them getting ST.2110 support at some point? I may have mis-remembered though.
