DPP Updates Technical & Metadata Standards

The DPP has unveiled additional key features of its common industry Technical & Metadata standards for file-based delivery of TV programmes to all major UK broadcasters.

The new (version 4.0) DPP standards, which are based on the AMWA AS-11, will go live on 15th October. The launch follows the DPP’s announcement at IBC that UK broadcasters will move to file-based delivery by October 1st 2014.

The standards, which have been widely adopted by manufacturers, producers and broadcasters, and are designed to have at least a five-year life span to allow consistency and product development, 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 Versions to allow for updates
  • Reduction in line-up and clock/slate time
  • 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 clarifications of the specification

Kevin Burrows, DPP Technical Standards Chair and Controller of Technical Broadcast and Distribution C4, said, “We have prepared the ground for file-based delivery over the past 18 months and the standards are now starting to pay dividends for producers, manufacturers and broadcasters.  The latest version updates the standards enabling a longer shelf life which we believe will create a more efficient and effective way of working across the industry for the future.”

*The release of the DPP technical standards includes compliance to the EBU R128 Audio Loudness specification. This has involved extensive work between the major UK Broadcasters and the TV Production and Post-Production community, resulting in standardised Audio Loudness guidance designed to ensure a consistency of approach to audio production and measurement.

The intention is that the Audio Loudness guidelines are phased in for newly commissioned productions by the UK Broadcasters.

The DPP is simultaneously launching an updated version of its free-to-download metadata application.  This version contains minor bug fixes and enhancements, details of which can be found on the DPP website.
