Wohler has launched a file-based processing system to work specifically with new UK broadcast delivery specifications, including loudness and channel format. It conforms to the UK Digital Production Partnership (DPP) standards for exchanging programme material from facilities and between broadcasters, which will move to completely databased operations from October this year.
WohlerDPP is described as a turnkey package that has been built on the RadiantGrid Intelligent Media Transformation platform. RadiantGrid vice president Craig Newbury comments that augmentations for WohlerDPP have been added to established technologies in the existing system.
Specific audio features include a loudness controller based on Linear Acoustics’ intelligent analysis and correction technology. Newbury adds there are also functions for channel mapping, Dolby encoding and decoding, down-mixing and up-mixing.
“The system is able to take a variety of files that post organisations have to deal with now,” Newbury comments. “In the past there have been thousands of permutations for audio structure as people had slightly different workflows, which was complex, but there is a move to a common structure with DPP.”
Facilities and other programme suppliers are now having to consider delivering DPP AS-11 files to broadcasters, with the added requirement for post-production houses to perform quality control checks (see feature).
