DPP unveils updated standards for file-based delivery

19 August 2013

The Digital Production Partnership will unveil additional key features of its common industry Technical & Metadata standards for file-based delivery of TV programmes to all major UK broadcasters. The changes will go live in early September.

The AMWA AS-11 and UK Broadcaster standards have been updated to include:

•    Audio Compliance to EBU R128 Loudness from traditional PPM levels
•    Inclusion of guidance on use for UHD (4K) cameras
•    Addition of Shim Version to allow for updates
•    Reduction in line-up and clock/slate time from three to one minute total
•    Optional addition for the carriage of multichannel audio metadata within a programme file
•    Removal of the requirement to deliver an associated sidecar xml file
•    General clarification of the spec

The DPP is a UK industry collaboration between broadcasters ITV, Channel 4 and the BBC. Its Metadata Application allows users to enter and embed the required data into the MXF programme files, making them compliant with the AS-11 DPP standard, and has been updated to support the Standards revisions.

Kevin Burrows, controller of Technical Broadcast and Distribution, C4 and DPP Technical Standards chair, said, “Having an agreed UK standard for file-based delivery across the industry that we can build on, is of great benefit in ensuring ease of exchange and the ability to incorporate future requirements.”

“It’s been a busy year for the DPP, with a lot of new initiatives coming to fruition, and we’re looking forward to sharing a number of important new developments in our work,” added Mark Harrison, DPP Forum & Production Futures lead and controller of Production, BBC North.
