SMPTE ST 2110 is a standard for audio and video transport over managed IP networks. It is commonly used in video production systems and is considered a replacement for SDI (Serial digital interface) based solutions.
Our Dante V3 option cards (SQ/AHM 32x32, 64x64 & Avantis/dLive 64x64, 128x128) support SMPTE ST 2110 from card firmware V1.0.2. This means any of these ‘Audio-only’ devices can interface directly with an ST 2110 system without the need to convert from other commonly used audio formats such as Dante or MADI.

ST 2110 vs AES67?
There are only minor differences between ST 2110 audio streams and AES67.
For example:
| Similarities | Differences |
|
AES67 and ST 2110 transport media packets over UDP/IP.
AES67 and ST 2110 use similar time synchronization mechanisms (PTPv2, boundary clocks).
|
Dante Domain Manager is optional for AES67 but required for ST 2110.
AES67 only uses the Primary network, whereas Dante devices with redundant ports support ST 2110 streams with SMPTE 2022-7 network redundancy. |
ST 2110 is largely aimed to streamline integration with video production systems where both audio and video are required over a network.
How do I configure my V3 Dante card for ST 2110?
SMPTE ST 2110 requires a secure Dante Domain for use with a Dante network (Dante Domain Manager V1.1 required). Once the network is in a secure domain, the SMPTE ST 2110 mode can be used.
In Dante Domain Manager, go to Domains > [Your Domain] > Advanced.
The Mode can now be changed to SMPTE.
Note: The Allen & Heath Dante card uses a 48kHz sample rate when using AES67 or SMPTE modes.
Default PTP (Precision Time Protocol) priority clock settings will now be applied and can be adjusted as required.
When configuring the transmission settings for the SMPTE ST 2110 device, the default UDP port is 5004 when used for Real-time Transport Protocols.
The ST 2110 device will also need to connect to your Dante Domain using SDP (Session Descriptor Protocol).
In Dante Domain Manager, go to Domains > [Your Domain] > Add Session.
A text file for the device should be available for this purpose. Please contact the manufacturer of the device if you need assistance.
Copy and paste the text file contents into the Descriptor field and click OK.
The SMPTE device is now present in Dante Controller and available for subscriptions.
