Teranex Mini IP Video 12G

PostThu Jul 27, 2017 12:49 pm

Has anyone got any of these units?

I am just wandering what the latency is like on these boxes.

If you have the 10G module installed can you use the 1G port to connect to another device. (Acting like a Switch).

Hello Phil. the latency is 35 lines in Low Latency Mode. It is 2 frames in Clean Switch Mode. Only one port can be used at a time. Hope that is helpful.

What bandwidth do the IP streams use

1.5G SDI = IP
3G SDI = IP
6G SDI = IP
12G SDI = IP

Also if you could use the other port this would allow network control of the endpoint Device (Projector / Camera)

Hello Phil. We use 4:1 Tico compression on everything.

Are you looking at creating a hdmi to ip module? Does the IP module work with multicast?

Yes, it works with multicast. There's a section on it in the Teranex manual (iirc) that is very informative.

+1 on this question please. Is this IP range going to be extended to include HDMI?

If so, I'm hoping it would include an in and out port on each unit so that all units can be changed between source/destination.

The prototype was based on the Optical to HDMI unit. See here a photo of the video where Grant Patty announched the IP unit.

I wish you could buy a license or upgrade the firmware to inco-oporate this on the the whole Optical series of the teranex.

Thanks Gary! While we're on feature requests then... if these units also had the ability to enable the 1G Ethernet network (for utility usage) whilst running the main video via fibre... you'd be really pushing the competition... This would allow an extra network sitting on top which could be used for all manner of connections - source and display control, ptz cameras, etc.

Presuming TICO leaves enough headroom within the 10G bandwidth of course.

Many thanks!

Are BlackMagic able to confirm whether the PTP clock on a network installation is an absolute requirement or just a recommendation? If it's a recommendation, what are the possible effects of not having this feature on the network switch?

Hello Chris. The PTP clock is not absolutely necessary. Without one, it may take some time, maybe up to a couple of minutes for the signal to lock in the system. This is not image latency but time when the signal is attached before it is locked. Having the PTP clock is highly recommended.

Thanks for the quick response Gary. Would this apply to the first unit in a videohub only - to establish itself as the master, or all subsequent units connected? and sources only? - I presume once they're on the system, they're on, so to speak and you can then switch at will? The PTP clock seems to be a tricky feature to specify on a switch - we're talking to a few manufacturers and it's one of the more elusive features.

Many thanks again

Without the clock any connections will be slow. When moving forward in an IP infrastructure, the PTP clock is going to be quite necessary and is defined by SMPTE. The clock only has to come from one unit in the network like a router. Doesn't need to be in every switch. But in the short term just be patient when connecting a signal.

Interesting stuff Gary - I've been reading up on the new SMPTE standards (2110). Is there a new release in the pipeline for BM due to this new standard? Is this the kind of thing that can be firmware updated in the current form of the Teranex mini or does it require a new chipset?

Has anyone got these units working. Im not an IT guy so forgive me if my question is stupid haha. I have 3 IP Video to 12G Teranex Mini's. I had 2 of them working, then I changed something and none of them work now lol. I am connecting them all to a Gigabit switch but im afraid I may have changed some IP address or something. Would someone be kind enough to walk me through this, maybe the dummy version? I turned the Wifi off on my laptop (MacBook Pro) and connected to the switch with a Cat5 Cable. What should the settings be? I dont know what a Subnet Mask is so im not sure if that should be corresponding with the units or not. Like I said, I basically know nothing about IT. Help would be very much appreciated. I spent 2hrs on the phone with Blackmagic support and we couldn't figure it out. Thanks in advance!

I'd say, adding hdmi in/out ports to the existing product would be the best solution

Hi Gary, I hope you're still watching this thread, I have a couple more questions about the clock I'm afraid!

We've spec'd a switch that supports PTP transparent clock (end to end) but only that, i.e. it contains no grand master clock itself and does not support ordinary or boundary clock features. Are you able to confirm if this is sufficient to work with the Teranex units, where the first connected device becomes the master clock and the others sync quickly as slaves?

Many thanks

Hi Chris,
Yes, in the case above, if theres no grandmaster capable clock available on the network. One of the Teranex Mini IP Video units will act as a grandmaster.
For it to work you will need to set up your switch correctly. You can extrapolate the details from Page 36 of the Teranex Mini IP Video Manual.

Hi,
anyone can help me to setup 2 teranex ip in my net?

My net:

-Cisco SG300
-n1 teranex mini ip----I set it as "source" my TX (" jumper 1 " is down and by usb cable software show me it is right set up as "source"

-n1 teranex mini ip----I set it as "destination" my RX (" jumper 1 " is up and by usb cable software show me it is right set up as "destination"

I try to work in dhcp and also static ip....but no way to work----no sdi signal from RX

After a lot of attempts....now when I connect ethernet to TX my net go crazy (everything go slowly and internet can't work)

Thanks in advance to anyone will help me

PS I wrote to blk magic support on friday but no answer

Hi Daniele.
To my knowledge it sounds like you've got a problem with IGMP (multicast) not working properly or at all. Could you check that these features are enabled on your switch?

These services will allow items to subscribe to the transmission stream (sender box) rather than the data being sent out to all ports - which is what would most likely cause your problem where all data is interrupted on the network.

I have E2E enabled on my switch, but all connected IP Video 12G units are registering as the master clock. When I plug in a new unit, it shows PTP 'listening' for a short while, then sets itself to master. This tells me that they are not receiving any PTP messages from the other units.

This appears to be causing a problem with the video signal dropping out on destination units every minute or so as it resynchronises (though this could be a misdiagnosis/incorrect assumption on my part).

So two questions, would non-functioning PTP result in these kind of behaviour (brief drops of signal)?

and can you give me any information on how PTP is implemented by the units in the absence of a separate grandmaster clock? The details on page 35 of the manual are specifically for configuring a standalone grandmaster clock, are there any specific switch configurations that I need to be aware of?

Many thanks

Hi all,

I have around 30x of the IP Video boxes, spread across 3 sites with a Cisco Nexus based WAN between them. We have the L3 multicast working well, and can see the stream on the multicast RP and the IGMP working well to initiate the LAN to LAN routing.

We do however have issues with intermittent drops of connection, and are looking to put a dedicated PTP GM in place.

Is there (or could there be) an engineering menu where we can see realtime status and potentially logs of what's going on with the boxes?

Hi Tim,

I've been using Wireshark and port mirroring to keep an eye on what communication is going on between the boxes, trying to diagnose my issues. PTP messages can certainly be seen this way which may help you? The PTP status of each box (listening, master, slave etc.) can only be seen when you have a smart panel attached which is an annoyance in a large network.

I have a similar number of boxes here running on a 10G LAN, but am having problems with the IGMP configuration, my mrouter port(s) (including the computer running the videohub control software) are getting flooded with the video data which is causing a number of problems. Would you be willing to share the details of your setup (switch configurations etc.)? I'm trying to get detailed network config info from BMD but information so far is sparse.

I did have an intermittent dropout issue previously which I thought may be a PTP issue, but turned out to be IGMP snooping issuing unwanted leave messages every minute or so. I ended up diagnosing this in my switch's configuration when I noticed that the leave message counter would increase by one with each 'drop out'.

Very best

Chris
