- EBU issues guidance on video signals and HDR video production
- Signal level guidance and HDR over SDI documents are practical guidance for industry members
- EBU also announces several promotions within media team
The European Broadcasting Union has published new documents that aims to help media professionals deal with misunderstandings that arise frequently around video signals and how to handle HDR in video production.
The signal level guidance and HDR over SDI documents are practical guidelines that aim to help the industry when producing content in HDR.
The first publication, EBU R 103 v3.0 – Video Signal Tolerance in Digital Television Systems, addresses confusion regarding the use of different video ranges. The most important one involves distinguishing between ‘full’ and ‘narrow’ range video.
The broadcasting industry currently uses nominal range video signals (mostly) which enables preservation of under- and over-shoots, avoiding clipping and related artefacts.
“The use of ‘full range’ video can also lead to misunderstandings,” the EBU wrote. “Video transferred over SDI has slightly fewer code values than video transferred as files can have, because SDI reserves some code values for synchronization (shown in red above). It thus is important to know if equipment interfaces expect ‘File-Full’ or ‘SDI-Full’ range video.”
The second set of guidance is on HDR over SDI, which is addressed in is addressed in the second publication: EBU Tech 3375 – Signalling and Transport of HDR and Wide Colour Gamut Video over 3G-SDI Interfaces.
The guidance has been issued by the EBU Video Systems Group in response to questions from EBU members about HDR signalling issues which they have encountered in real-world SDI infrastructures.
The guidance outlines how HDR signalling works when producing in 1080p/25 or 1080p/50, setting out what should be specified and tested for, to guarantee interoperability.
Both sets of guidance can be found on the EBU’s website here.
EBU promotes media department management team
The EBU has announced two senior promotions in the management team of its media division.
Matthew Trustram, a senior EBU project manager with more than 10 years’ experience at the organisation, has been named as the EBU’s head of television, replacing Jeroen Depraetere, who left in December 2019.
The group has also promoted head of digital Ezra Eeman to an extended role as head of digital, transformation and platforms. This will see the former VRT executive steer the EBU’s media activities in distribution and promotion.
“EBU Media supports members with distinctive content and advises on connecting with audiences – services that have been thoroughly tested during the COVID-19 pandemic. The virus has proved beyond doubt that the role of EBU as content partner is needed like never before,” said EBU media director Jean Philip De Tender.
“As part of our drive to renew and strengthen our services for members, we will prioritise a focus on content, platforms and distribution across all media so that we can respond better to strategic needs and the changing media landscape. The roles of head of television and head of digital, transformation and platforms are key to this renewed focus, as we shape our portfolio provision for the future.”
