Video: User Requirements Beyond SMPTE ST 2110

Work on ST 2110 continues although the main elements of it have been standardised for well over a year now, but many companies are thinking beyond ST 2110.

The EBU’s Willem Vermost presents the wider picture of next generation broadcast facilities charting the need and desires of public broadcasters in Europe. We look here at the need for many broadcasters to move buildings and the problems they face doing so – only one of them being implementing a ST 2110 infrastructure.

The talk then goes on to the problems that broadcasters face and the need for a way of working which defines some common approaches. This has arrived in the form if a document with the lengthy title JT-NM TR-1001-1:2018 which outlines many practical approaches to making ST 2110 work. Many are simple, such as using DHCP but without an agreed set of practices, incompatibilities will come in.

Willem talks about the interoperability tests for this, the results of which are publicly available rather than previous closed-door tests. And before rounding off the talk with questions, he looks at the increasingly well-known EBU Pyramid which shows the availability of different parts of the IP ecosystem; media transport being green, configuration and security being red.

For more information about JT-NM, look at this talk from SMPTE and Imagine Communication’s John Mailhot which covers it in much more detail.

Join Willem at IBC to find out more about ST 2110 at a panel from IET Media discussing ST 2110 and NDI. NDI provides video over IP and is more widely supported than ST 2110, yet major broadcasters seem blind to its benefits. Is this because NDI doesn’t meet the needs of these broadcasters or are there other reasons? What are the use cases where both can be used together?

Join Willem Vermost, The Broadcast Knowledge Editor Russell Trafford-Jones, Marc Risby CTO of Boxer and Liam Hayter from Newtek/NDI to find out more at IBC, IABM Theatre, Future Zone. Friday 13th 15:00-15:45.

Video: Network Automation Using Python and Google Sheets

“I’m lazy and I’m a master procrastinator.” If you sympathise, learn how to automate network configuration with some code and spreadsheets.

In this video, the EBU’s Ievgen Kostiukevych presents a simple way to automate basic operations on Arista switches working in a SMPTE ST 2110 environment. This is done with a Python script which retrieves parameters stored in Google Sheets and uses Arista’s eAPI to implement changes to the switch.

The Python script was created as a proof of concept for the EBU’s test lab where frequent changes of VLAN configuration on the switches were required. Google Sheets has been selected as a collaborative tool which allows multiple people to modify settings and keep track of changes at the same time. This approach makes repetitive tasks like adding or changing descriptions of the ports easier as well.

Functionality currently supported:

  • Creating VLANs and modyfying their descriptions based on the date in a Google Sheets
  • Changing access VLANs and interface descriptions for the ports based on the date in a Google Sheets
  • Reading interfaces status and the mac address table from the switch and writing the data to the spreadsheet

The script can be downloaded from GitHub.

Video: Building Large SMPTE ST 2110 Systems Using JT-NM TR-1001-1


With the SMPTE 2110 suite of standards largely published and the related AMWA IS-04 and -05 specifications stable, people’s minds are turning to how to implement all these standards bringing them together into a complete working system.

The JT-NM TR-1001-1 is a technical recommendation document which describes a way of documenting how the system will work – for instance how do new devices on the network start up? How do they know what PTP domain is in use on the network?

John Mailhot starts by giving an overview of the standards and documents available, showing which ones are published and which are still in progress. He then looks at each of them in turn to summarise its use on the network and how it fits in to the system as a whole.

Once the groundwork is laid, we see how the JT-NM working group have looked at 5 major behaviours and what they have recommended for making them work in a scalable way. These cover things like DNS discovery, automated multicast address allocation and other considerations.

Webinar: Measuring and Visualising Live IP Traffic


Webinar: 14 Jun 2018, 15:00 BST

This Webinar provides an introduction to the Live IP Software Toolkit (LIST), and how and what to use it for.
Shining a light on media streams.

IP-based networks make for powerful production infrastructures because they are content-agnostic, scalable, and, in principle, flexible.

Understanding what is going on in your Live IP infrastructure is important. Are your senders transmitting according to the specifications? Does your PTP timing reference perform within proper limits? Without new tools, administrators are blind to such factors. That is where LIST comes in.

The Live IP Software Toolkit allows administrators to inspect production network traffic and visualize streams. It is closely aligned with SMPTE 2110 and related standards. LIST is currently a minimum viable product and open source.
