The Technology Pyramid For Media Nodes

This PowerPoint slide shows the EBU 'Pyramid' graphic, based on EBU Tech 3371. It details the 'Minimum Stack' of protocolls needed to achieve plug-and-play interoperability in ST-2110-based LiveIP production infrastructures.

This PowerPoint slide shows the EBU 'Pyramid' graphic, based on EBU Tech 3371.

Industry-wide consensus on all layers of interoperability between individual systems in an LiveIP production environment would remove most of the remaining hurdles faced by system architects when moving from the drawing board to the actual implementation of a facility design. This slide explains the minimal set of relevant layers and standards that, once properly orchestrated, would greatly reduce the complexity of building and maintaining facilities based on the 'lingua franca' of many modern high-performance IP production environments – the SMPTE ST 2110 standard. It proposes protocols required in order to enable missing functionalities such as unit discovery, automatic allocation for multi-cast IP addresses, PTP management, and more.

EBU Tech 3371 and the Pyramid are maintained by the EBU Strategic Programme on Infrastructures and Security.
