Video: Wide Area Facilities Interconnect with SMPTE ST 2110

Adoption of SMPTE’s 2110 suite if standards for transport of professional media is increasing with broadcasters increasingly choosing it for use within their broadcast facility. Andy Rayner takes the stage at SMPTE 2019 to discuss the work being undertaken to manage using ST 2110 between facilities. In order to do this, he looks at how to manage the data out of the facility, the potential use of JPEG-XS, timing and control.

Long established practices of using path protection and FEC are already catered for with ST 2022-7 for seamless path protection and ST 2022-5. New to 2110 is the ability to send the separate essences bundled together in a virtual trunk. This has the benefit of avoiding streams being split up during transport and hence potentially suffering different delays. It also helps with FEC efficiency and allows transport of other types of traffic.

Timing is key for ST 2110 which is why it natively uses Precision Timing Protocol, PTP which has been formalised for use in broadcast under ST 2059. Andy highlights the problem of reconciling timing at the far end but also the ‘missed opportunity’ that the timing will usually get regenerated therefore the time of media ingest is lost. This may change over the next year.

The creation of ST 2110-22 includes, for the first time, compressed media into ST 2110. Andy mentions that JPEG XS can be used – and is already being deployed. Control is the next topic with Andy focussing on the secure sharing of NMOS IS-04 & 05 between facilities covering registration, control and the security needed.

The talk ends with questions on FEC Latency, RIST and potential downsides of GRE trunking.

Video: MPEG-5 EVC

The MPEG-5: Essential Video Codec (EVC) promises to do what no MPEG standard has done before, deliver great improvements in compression and give assurances over patents. With a novel standardisation process, EVC provides a royalty-free base layer plus licensing details are provided upfront.

SMPTE 2019 saw Jonatan Samuelson take us through the details. Founder of Divideon and an editor of the evolving standard. Jonatan starts by explaining the codec landscape in terms of the new and recent codecs coming online showing how EVC differs including from it’s sister codec, VVC in parallel with which EVC is being developed.

Jonatan explains how the patents are being dealt with, comparing to HEVC, he shows that there is a much more simplified range of patent holders. But importantly, the codec has very granular tools to turn on and off separate tools so that you can exclude any that you don’t wish to use for licensing reasons. This is the first time this level of control has been possible. Along with the royalty-free base layer, this codec hopes to provide companies the control they need in order to safely use the codec with predictable costs and without legal challenges.

Target applications for EVC are realtime encoding, video conferencing but also newer ’emerging’ video formats such as 8K with HDR & WCG. To do this, Jonatan explains the different blocks that create the codec itself ahead of walking us through the results.

Webinar: Networking Fundamentals


Date: Thursday 12th December, 1pm EST / 18:00 GMT

Networking is increasingly important throughout the broadcast chain. This webcast picks out the fundamentals that underpin SMPTE ST 2110 and that help deliver video streaming services. We’ll piece them together and explain how they work, leaving you with more confidence in talking about and working with technologies such as multicast video and HTTP Live Streaming (HLS).

Video: Talk 2110

Is the industry successfully delivering what we need with SMPTE’s ST 2110 suite of standards? What are the benefits of IP and how can we tackle the difficulties?

In this panel from Broadcast Solutions’ Innovation Day, we hear from 5 vendors understanding their perspectives and plans for the future. Claus Pfeifer from Sony say they have now 60 sites up and running in IP. Lawo’s Phil Myers follows up saying “People know they have to go IP, it’s a matter of when they go IP.”

Whilst this is a positive start, the panel moves on to talking briefly about difficulties implementing SMPTE ST 2110. Jan Eveleens from Riedel points out many of the issues will go as we are waiting for technology to catch up regarding CPUs and bandwidth. We no longer have the same processing issues we used to for audio. Similarly with video, technology will improve and remove many of the challenges. Phil Myers feels that cloud implementation issues are not a large problem at the moment as he sees a move to bring equipment into private clouds rather than public. This way they are doing ‘remote production for buildings’.

After each vendor outlined their future plans for IP, Zoltan highlighted that IP allows NDI to co-exist with ST 2110. Many may want to use 2110 for high end sports, for others NDI fits well. Then panel felt that a concerning area of IP is the worry of how to fix problems. The knowledge level is different from country to country. So vendors not only need to work on education about IP, both for NDI and 2110, but they need to do this in a focussed way for the different markets.

As the panel comes towards the end, Claus feels that the industry started to talk too early about pure technology. “Did not discuss enough about the business benefits.” he explains such as remote production and more efficient use of equipment – avoiding ‘sleeping Capex’. Installing IP makes a lot of sense for large-scale systems. Recently broadcasters have been working at a scale requiring much more than 1024 squared routers roughly where SDI routers top out. But also, these large systems tend to have a life of over 10 years. Faced with SDI development, particularly in routers, is slowing down or stopping, for these long-lived systems it makes much more sense to use IP.
