The EBU has published an updated version of Tech 3371 and its 'Technology Pyramid for Media Nodes' graphic, a visual representation of user requirements, priorities and the market’s progress in creating and implementing relevant supporting standards and protocols in the SMPTE ST 2110 ecosystem of LiveIP technology. One of the most striking changes is that the Pyramid is greener now, reflecting a greater maturity of product implementations overall, relative to what the earlier version showed. Some layers of the pyramid were also renamed.

The Pyramid is effectively a gap analysis and forms part of the 'Minimum User Requirements to Build and Manage an IP-based Media Facility using Open Standards and Specifications' defined in EBU Tech 3371. It was designed specifically to highlight collective requirements and to encourage the adoption of open (non-proprietary) standards and specifications by vendors, in an effort to make deployments as easy and cost-effective as possible.

The updated Pyramid graphic is available as a PowerPoint slide for download.

What changed

Maintaining the strong focus on the end-user’s perspective, EBU Tech 3371 and the Pyramid were updated to reflect observations and address issues encountered by EBU Members during some of the largest LiveIP deployments of recent years. Version 2 adds or updates the following user requirements:

  • Support for adaptive buffer sizes with manual user override on the SMPTE ST 2110-21 level
  • Support for level B instead of level C on the SMPTE ST 2110-30 level
  • More detailed PTP performance and monitoring
  • Support for IS-07 or other Open Device Control method
  • DHCP and DNS support
  • IS-09 System Parameters Specification
  • Support for AMWA BCP-003-01 and BCP-003-02

The Pyramid and EBU Tech 3371 are maintained by the EBU Strategic Programme on Infrastructures and Security. The Strategic Programme is governed by the EBU’s Technical Committee and run under the umbrella of the EBU Technology & Innovation department.
