SMPTE Publishes ST 2110 Standards

The first documents of the SMPTE ST 2110 standards suite are now available, it has been announced.

SMPTE has published the first standards within SMPTE ST 2110, Professional Media Over Managed IP Networks; a new standards suite that specifies the carriage, synchronisation, and description of separate elementary essence streams over professional IP networks in real-time for the purposes of live production, playout, and other professional media applications.

Now available in the SMPTE digital library are the documents:

• SMPTE ST 2110-10/-20/-30 – addressing system concerns and uncompressed video and audio streams
• SMPTE ST 2110-21 – specifying traffic shaping and delivery timing of uncompressed video.

With SMPTE ST 2110 standards, intrafacility traffic now can be all-IP, allowing organisations to rely on one common data centre infrastructure, rather than two separate facilities for SDI and IP switching/routing. The foundation for the first SMPTE ST 2110 standards came from the Video Services Forum (VSF) Technical Recommendation for Transport of Uncompressed Elementary Stream Media Over IP (TR-03), which VSF agreed to make available to SMPTE as a contribution toward the new suite of standards.

SMPTE ST 2110 standards make it possible to separately route and break away the essence streams (audio, video, and ancillary data). This advance simplifies, for example, the addition of captions, subtitles, and teletext, as well as tasks such as the processing of multiple audio languages and types. Each essence flow may be routed separately and brought together again at the endpoint. Each of the component flows – audio, video, and ancillary data (there may be multiple streams of each type) – is synchronized, so the essence streams are co-timed to one another while remaining independent.

The new SMPTE ST 2110 standard suite was a primary focus of the IP Showcase at SMPTE 2017, where SMPTE joined with the Audio Engineering Society (AES), Alliance for IP Media Solutions (AIMS), Advanced Media Workflow Association (AMWA), European Broadcasting Union (EBU), IABM, Media Networking Alliance (MNA), and Video Services Forum (VSF) to support the event. The IP Showcase featured the latest advances in IP technology for the professional media industries and demonstrated how the SMPTE ST 2110 standard suite adds value. Numerous interoperability demonstrations assisted broadcast/IT engineers, CEOs, producers, and others in understanding how they can leverage the benefits of SMPTE ST 2110 standards.

SMPTE President Matthew Goldman, Senior VP of Technology, TV and Media at Ericsson, said: "Professional media is a uniquely challenging field because of its real-time nature and high quality-of-service requirements, both of which consumers may take for granted. The standardization of SMPTE ST 2110 documents provides broadcasters, producers, and media technology suppliers with the tools they need to meet these requirements while working in the IP realm."

SMPTE is currently developing a dedicated course on ST 2110 for its Virtual Classroom which will be offered beginning in February 2018.
