SDI redundant paths required a frame sync to switch in to aid with a seamless switch over to a redundant feed. Not so with IP. The SMPTE ST 2022-7 is the standard for seamless protection which is packet-based, so no frame sync is required. Merrick Ackermans (Principal Engineer, MVA Broadcast Consulting) explains how this works with SMPTE ST 2110 streams.

Daniel McDonnell (Managing Director, Timeline Television) discusses Timeline Television’s triple expanding, 32-camera IP 4K HDR outside broadcast truck, UHD2. With an Arista 100G switch at its heart and SAM IP infrastructure, UHD2 delivers large-scale complex OBs simultaneously in uncompressed 4K UHD HDR and 4K UHD SDR. UHD2 is based around the SMPTE ST 2110 standard, enabling both audio and video to be processed in the IP stream.

Mark Patrick (Lead Architect, BBC Design & Engineering) is working on the technical delivery of Cardiff Central Square, the new home for BBC Wales. This project is delivering a whole new broadcast headquarters with state-of-the-art facilities and it includes an IP based ‘Live Core’ routing system built on SMPTE ST 2110 and NMOS standards. Mark will give an overview of why IP based solutions have been chosen for the project and progress to date including selection of systems, detailed design and testing.

With standards now ratified, Mark Davies (Director of Products & Technology, TSL Products) shares his experience with real live IP production deployments. These include some of the world’s first IP trucks and fixed studios and the challenges of living up to the format-agnostic promise as early deployments of SMPTE ST 2022-6 mature in record time and transition to SMPTE ST 2110. Not forgetting this new technology still needs to be controlled, timed and secure.

When published in late 2017, SMPTE ST 2110 consisted of parts -10, -20 and -30 which cover the fundamental definitions for synchronization and transport of elementary essence for uncompressed video and audio. Meanwhile, further parts of the standard have been, or are to be released shortly, including definitions for AES3 transparent transport. This presentation from Andreas Hildebrand (Technology Evangelist,
ALC NetworX GmbH) provides an overview and update on the audio parts of SMPTE ST 2110, including their relationship with AES67.

Why is there a separate SMPTE ST 2110-30 standard from AES67? Are AES67 devices compatible with SMPTE ST 2110-30? Why is there a SMPTE ST 2110-31 standard? This presentation from Leigh Whitcomb (Architect, Imagine Communications) is a deep dive into the SMPTE ST 2110-30, 31 and AES67 audio and will answer all these questions.

In 2013, Microsoft Production Studios began pioneering work on a property-wide audio-over-IP production workflow. Through its ties to MSNBC, it forged relationships and shared knowledge with other broadcasters charting the same frontier. In this session, John Ball (Systems Engineer, Microsoft Production Studios) shares practical experience – both successes and lessons learned. Also, as Microsoft has already begun the infrastructure upgrades to accommodate a SMPTE ST 2110 video workflow, practical comparisons can be drawn on the adoption process for audio and video.

We have heard about interoperability, microservices and vendors collaborating, so what does this mean for standards? Are industry standards such as SMPTE ST 2110 more important than ever – or an anachronism in an age driven by IT? What about other emerging standards such as NDI? Two leading systems integrators, who have delivered IP projects in the wild, debated the importance of standards in the transition to IP, and asked whether they are always answering the right question.

In this presentation Ed Calverley (Product Director, Suitcase TV) looks at how the current standards work is enabling true end-to-end IP-based production and how standards such as SMPTE ST 2110 enable systems to interoperate in a much more flexible way than was possible with SDI.
