Video: Introduction to IPMX

The Broadcast Knowledge has documented over 100 videos and webinars on SMPTE ST 2110. It’s a great suite of standards but it’s not always simple to implement. For smaller systems, many of the complications and nuances don’t occur so a lot of the deeper dives into ST 2110 and its associated specifications such as NMOS from AMWA focus on the work done in large systems in tier-1 broadcasters such as the BBC, tpc and FIS Skiing for SVT.

ProAV, the professional end of the AV market, is a different market. Very few companies have a large AV department if one at all. So the ProAV market needs technologies which are much more ‘plug and play’ particularly those in the events side of the market. To date, the ProAV market has been successful in adopting IP technology with quick deployments by using heavily proprietary solutions like ZeeVee, SDVoE and NDI to name a few. These achieve interoperability by having the same software or hardware in each and every implementation.

IPMX aims to change this by bringing together a mix of standards and open specifications: SMPTE ST 2110, NMOS specs and AES. Any individual or company can gain access and develop a service or product to meet them.

Andreas gives a brief history of IP to date outlining how AES67, ST 2110, ST 2059 and the IS specifications, his point being that the work is not yet done. ProAV has needs beyond, though complementary to, those of broadcast.

AES67 is already the answer to a previous interoperability challenge, explains Andreas, as the world of audio over IP was once a purely federated world of proprietary standards which had no, or limited, interoperability. AES67 defined a way to allow these standards to interoperate and has now become the main way audio is moved in SMPTE 2110 under ST 2110-30 (2110-31 allows for AES3). Andreas explains the basics of 2110, AES, as well as the NMOS specifications. He then shows how they fit together in a layered design.

Andreas brings the talk to a close looking at some of the extensions that are needed, he highlights the ability to be more flexible with the quality-bandwidth-latency trade-off. Some ProAV applications require pixel perfection, but some are dictated by lower bandwidth. The current ecosystem, if you include ST 2110-22’s ability to carry JPEG-XS instead of uncompressed video allows only very coarse control of this. HDMI, naturally, is of great importance for ProAV with so many HDMI interfaces in play but also the wide variety of resolutions and framerates that are found outside of broadcast. Work is ongoing to enable HDCP to be carried, suitably encrypted, in these systems. Finally, there is a plan to specify a way to reduce the highly strict PTP requirements.

Video: How CBC/Radio-Canada Tested Media-over-IP Devices to Build its New Facility

Moving video production to IP has been ongoing for over 5 years using both SMPTE ST 2022-6 and now ST-2110 but we’re still in the ‘Early Adopter’ phase, explains the Willem Vermost speaking at SMPTE 2019. Willem is the EBU topic lead for the transition to IP-based studios and he is tracking the upcoming projects with public broadcasters.

Willem talks about what’s motivating these Early Adopters. In general, he explains, they have a building move project and they are faced, as CBC (Canadian Broadcasting Corporation) was, with being the last to install an extensive SDI infrastructure – and be stuck with that for 7, 10 or more years to come – or the to be one of the first to use IP. Increasingly, they can’t justify the SDI workflow and IP, for all its risks and uncertainties, is the way forward.

CBC/Radio Canada needs to be ‘on air’ in 2020 so they put in a place a risk mitigation plan to test all the equipment before putting it in. Willem outlines what this test plan looks like and what it covers: AES67, ST 2110-40,-7, -30-, -20, EBU r148 security etc. Testing was also brought up by the BBC’s Mark Patrick when he discussed his work in bring in the BBC’s Cardiff Square building on-air. They found that automated testing was key in project delivery so that testing was quick and consistent to ensure that software/firmware patches were correctly accepted into the project.

Willem talks us through the EBU’s famous Technology Pyramid which shows to what extent each of the technologies on which media-over-IP requires has been defined and adopted by the industry. It shows that while the media aspect has been successfully deployed, there is a lot to do in, for example, security.

Difficulties arose due to different interpretations of standards. To aid in diagnosis of such issues, the LIST project has created a 2110 analysis tool and other related tools. This is created within the EBU and Willem highlights some key parts of what it does. He then shows how that connects in with the automated test programs and explains the underlying structure of how the software is built.

The talk finishes with mention of the JT-NM test plan, a summary and questions lead by Arista’s Gerard Phillips.

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: TR-1001 Replacing Video By Spreadsheet

Here to kill the idea of SDNs – Spreadsheet Defined Networks – is TR-1001 which defines ways to implement IP-based media facilities avoiding some typical mistakes and easing the support burden.

From the JT-NM (Joint Taskforce – Networked Media), TR-1001 promises to be a very useful document for companies implementing ST-2110 or any video-over-IP network Explaining what’s in it is EEG’s Bill McLaughlin at the VSF’s IP Showcase at NAB.

This isn’t the first time we’ve written about TR-1001 at The Broadcast Knowledge. Previously, Imagine’s John Mailhot has dived in deep as part of a SMPTE standards webcast. Here, Bill takes a lighter approach to get over the main aims of the document and adds details about recent testing which happened across several vendors.

Bill looks at the typical issues that people find when initially implementing a system with ST-2110 devices and summarises the ways in which TR-1001 mitigates these problems. The aim here is to enable, at least in theory, many nodes to be configured in an automatic and self-documenting way.

Bill explains that TR-1001 covers timing, discovery and connection of devices plus some of configuration and monitoring. As we would expect, ST-2110 itself defines the media transport and also some of the timing. Work is still to be done to help TR-1001 address security aspects.
