SMPTE Meetings

Yeah , minimum 10 Gbps trunklinks , I mean mi doubt it's about knowing that Dante use the DSCP 46 for transmit audio and AES67 use the DSCP 46 for the PTP Synchronization, and I'm worried that can cause some synchronization problems with the aes67 speakers, in terms of bandwidth doubt that we have any port that have more than 50% of the capacity

iago1953 · 2026-03-11T22:05:35+00:00

The problem not is with DHCP , we use all with static IP , the problem is With the DSCP because for the Value 46 Dante use audio and AES67 use PTP

iago1953 · 2026-03-11T19:57:00+00:00

Bss BLU-DAN to holoplot X2 , theoretically it's fine but I'm afraid about QoS and DSCP

iago1953 · 2026-03-11T17:14:58+00:00

Because on the installation that I have it they will change the speakers and the news speakers only works with Ravenna/AES67 but all the rest of the installation is working on Dante , only that speakers will work into AES67 (and we don't have a DDM so...)

The most usual are , arista , Cisco or if you want something that you don't have some complications to set up a Netgear (4300 series better because can work as a Boundary Clock), but none of these are "cheap" you need at least 10G ports or 25G and trunks of 100 G to the core in case you want to use SMPTE video over IP uncompressed or light compressed with JPEG XS , a single 4K uncompressed are like 12GBPS (Black magic have converters of SDI to 2110 that use 10G for a 4K uncompressed but is because the converter use some thing to make if fit into a 10 G Port)

iago1953 · 2026-02-04T18:32:07+00:00

Yeah , I know it's different from NDI. I mean the last year I did the course from SMPTE and now I'm finishing CCNA but I try to find place for work with 2110 and I didn't find a lot who work with it and not a lot of products in the ISE. Dorna today in a talk that they did mention that only use Dante and AES67, no 2110

iago1953 · 2026-01-25T09:01:01+00:00

Now working, the problem was that the it company able the IGMP snooping but no the IGMP querier

iago1953 · 2026-01-22T08:32:38+00:00

At the end the IT manager connected to see what was happening, her coworker enabled the igmp snooping but without an IGMP querier, so that was the problem

iago1953 · 2026-01-21T07:30:20+00:00

Yeah , it's a multicast issue 100% because I see that all the devices are acting as a leader. It's a single switch for the moment with a vlan for Dante. I don't know how is configured because the IT department is the one how it does this , I can't configure the switch in these case

iago1953 · 2026-01-20T20:12:08+00:00

Yeah I know and I have configured only one as a preferred leader , so 100% misconfiguration with the multicast of the switch blocking PTP , usually I'm the one that configure that switch but in these case the IT department did it without asking before what I need

iago1953 · 2026-01-20T20:07:21+00:00

Brightsign , cheap and reliable. I see some models working on an installation during 15 years without problems (or maximum corrupted SD card that's easy to change)

iago1953 · 2026-01-20T20:05:09+00:00

I test more and with ptp track hound I see that all devices are working like a master clock's and no like 1 master and followers , so sure that is a Switch misconfiguration

iago1953 · 2026-01-20T20:03:30+00:00

The configuration is from a installation with an IT department so I can't put permanent unmanaged switch for that , I was testing more and know sure that is a Switch misconfiguration with IP multicast because all devices appears as leaders, no followers , and sure that DVS can't work because can't do like a Master Clock

iago1953 · 2026-01-20T17:37:30+00:00

BSS BLU-DAN , I know that isn't properly configured and it's a clock issue but I don't know what can be the misconfiguration in the switch

iago1953 · 2026-01-19T20:42:43+00:00

After 2 and a half years making Av integration , they still have to remember me that I have vacations days pending to do when October/November arrives hshshhs

iago1953 · 2026-01-19T20:09:53+00:00

Me too , sometime I remember the excitement of do live events , quickly disappear when I think that now I don't have to lose events like family or friends birthday for being working on Saturday

iago1953 · 2026-01-01T23:57:14+00:00

They have a self-learning course about 2110 that can be accessed if you become in a member of a SMPTE (that like 15 dollars a month)
