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.
