SMPTE ST 2110 enables IP workflows

By Tom Coughlin

At IBC2017 and this year’s SMPTE Conference there were significant demonstrations of IP-based workflows with interoperability demonstrations and conference sessions. Clearly proprietary media networking will be supplanted by IP-based workflows. This will enable new equipment economies and open up new opportunities for using and repurposing media. IP workflows will also impact the way we store and use digital content and thus the storage systems where they live.

SMPTE has just ratified ST 2110 standards for IP transport in media workflows. The standard puts video, audio and ancillary data into separate routable streams as shown in the figure below. PCM Audio streams are covered by SMPTE ST 2110-30, uncompressed video streams are covered by ST 2110-20 and ancillary data is covered by ST 2110-40. Some other parts of the standards cover traffic shaping of uncompressed video (ST 2110-21), AES3 transparent transport (ST 2110-31) and ST 2110-50 allows integration with older specification ST 2022-6 that covers legacy SDI over IP.

The separate streams have timestamps that allow proper alignment of the different streams when they are combined together — this timestamp is provided by ST 2059. Each stream contains metadata that tells the receiver how to interpret what is inside of the stream. The uncompressed video stream supports up to 32k X 32k images, HDR and all common color systems and formats.

The important thing about these IP standards is that they allow using conventional Ethernet cabling rather than special proprietary cables. This saves a lot of money on hardware. In addition, having an IP-based workflow allows easy ingest into a core IP network and distribution of content using IP-based broadcast, telco, cable and broadband technologies as well as satellite channels. As most consumers have IP content access, these IP networks connect directly to consumer equipment. The image below from an Avid presentation by Shailendra Mathur at SMPTE 2017 illustrates the workflow below.

At IBC and the SMPTE 2017 Conference there were interoperability demonstrations. Although the IBC interop demo had many more participants the SMPTE demo was pretty extensive. The photo below shows the SMPTE interoperability demonstration setup.

As many modern network storage systems, whether file or object based, use Ethernet connectivity, having the rest of the workflow using an IP network makes movement of data through the workflow to and from digital storage easier. Since access to cloud-based assets is also though IP-based networks and these can feed CDNs and other distribution networks, on-premise and cloud storage interact through IP networks and can be used to support working storage, archives as well as content distribution libraries.

IP workflows combined with IP-based digital storage provide end-to-end processing and storage of data. This provides hardware economics and access to a lot of software built to manage and monitor IP flows to help optimize a media production and distribution system. By avoiding the overhead of converting from one type of network to another the overall system complexity and efficiency will be improved, resulting in faster projects and easier repair of problems when they arise.

Stan Moote named CTO for IABM

The IABM (International Association of Broadcast Manufacturers) has tapped Stan Moote as its CTO. Moote began his television career in 1977 while interning as a plant engineer for CFTO-TV in Toronto, during the co-op component of his engineering degree from University of Waterloo. In 1980, he co-founded Digi-tel, Inc. and was responsible for the design and development of various digital video products before bringing his talents to bear at Leitch in 1984.

Moore was involved in the SMPTE Digital Video Standards Committee meetings creating CCIR-601 and continued his standardization work on video transport by being on the VSF (Video Services Forum) board of directors, 2001 to 2004. Stan is an active member of the ‪NATAS Technical Emmy Committee.

While holding VP/CTO positions at Leitch and Harris, he focused on workflow solutions, new technology, standardization and interoperability on a global basis. Moote developed several patents including scrambling systems, data monitoring, multi-viewer, router processors and IPTV systems.

Peter White, CEO of the IABM says, “Stan’s appointment comes at a time when the IABM is experiencing growth in both its membership and events delivery. Stan will contribute to IABM’s technology thought leadership and will assume responsibility for the development and scope of technical boards, committees, technology events and assist and formulate growth strategies in the North American and APAC regions.”

“The future direction of the broadcast and media industries is heavily based on quickly changing technologies,” says Moote. “With a strong member base, IABM is poised to give clear understanding of the issues that need to be addressed to keep the industry strong. I urge the membership’s CTOs and technical VPs to contact me directly, so we can work together helping end users meet their strategic goals.”

In related news, Moote, is set to be awarded the Society of Motion Picture and Television Engineers SMPTE 2015 Digital Processing Medal Award. First established in 2012, the SMPTE Digital Processing Medal Award recognizes significant technical achievements related to the development of digital processing of content for motion picture, television, games or other related media. Moote will receive the 2015 award for development of the first reliable video/audio scrambling system for composite analog video and analog audio in the early 1980s. This system digitized the analog signal, scrambled it, and reconstructed an analog signal that could be transmitted over satellite or microwave links with complete security. The system was granted both Canadian and US patents. Moote subsequently went on to serve as president and chief executive officer (CEO) of Leitch Technology International before returning to engineering management. He also assisted in the invention of the video multiviewer, for which he received a patent. Moote became chief technology officer (CTO) at Leitch just before its acquisition by Harris Corporation.

IABM webinar breaks down Tech Emmy application process

The IABM is hosted an interactive webinar this week about the requirements for winning a technical Emmy Award. The Road to Winning a Technical Emmy explored the scope of the Outstanding Achievement in Technology and Engineering Development Award, including the nomination process, committee selection procedures and a review of the Emmy usage policy.

Broadcast vet Stan Moote (pictured), who has been actively involved with the National Academy of Television Arts and Sciences (NATAS) Engineering & Technology Committee for two decades, was the presenter.

“The Emmy is one of the industry’s most iconic and sought-after awards,” reports Peter White, CEO, IABM. “It not only represents support of arts and science in television, it also means that having an Emmy statuette on your stand at a trade show, or in a display case in your office, reinforces your expertise and competency to both customers and peers.

“However, many IABM members don’t understand the process and shy away from entering as they consider it too complicated and the goal of winning the Emmy unachievable. This webinar is seeking to change that, to help organizations within the broadcast and media supply industry get their achievements recognized.”

While the webinar was free to those who signed up, it will be archived for IABM members to access going forward.
