HDR-Colour Volume – Colour difference metrics in 3D
With the move from SDR to HDR colours and the corresponding higher luminance range of HDR there seems to be a need to visualise and evaluate certain measurements in 3D as well.

Tool for codec-independent NGA productions released
We are very proud to inform you about the first public release of the “EAR Production Suite”, a free set of tools for producing immersive and personalizable audio content independently from the distribution codec. This open-source project has been developed in (yet) another great collaboration with our colleagues from the BBC R&D audio team under …
UHD – what it is about!
Ultra-High Definition – better known as UHD – has been a common term for several years. With it, television viewers benefit from a higher picture quality. But what exactly is behind UHD? We have examined UHD in more detail and with the help of an extensive subjective test we found out which visual factors have …
Testing a VR subtitle production prototype
In our earlier post on accessibility services in 360° environments (here) we have described how these services can enhance user experiences and make 360° videos more accessible. In the EU-funded Immersive Accessibility project ImAc subtitles are extended with guiding cues to support easier speaker identification within the 360° space to enhance the user experience and …
IRT & LMU Cooperation: Augmented Reality in the Broadcast World
The hype about Augmented Reality (AR) is slightly going down even though the advantages remain. Especially for broadcasters the advantages of AR can be used in a variety of domains, like material planning, broadcast production, graphic development and marketing. However, AR is still a new territory for editorial and production staff. We, at the IRT, …
TV-Based Augmented Learning
Augmented Reality (AR) is hyped for some years now and shows a lot of potential. Among other advantages, there were already successes in the educational system with the use of AR to teach factual content. In 2019 IRT investigated the integration of an AR application into educational television in the form of a student thesis. …
HDR-Colour Volume – Colour Space Visualization in 3D
Ultra-High Definition Television (UHDTV) as it is specified in ITU-R BT.2100 consists of four main features compared to the current legacy HDTV format (High Definition Television): High Resolution (e.g. 2160 lines, progressive only) High Frame Rate (HFR) High Dynamic Range (HDR) Wide Colour Gamut (WCG). Investigations and various demonstrations (e.g. at IFA or IBC 2019 …
Combining our NGA efforts in an open-source ADM production tool
If you are following our work towards a truly open and codec-independent workflow for Next Generation Audio, you will have noticed that we not only work together with other broadcasters and industry representatives to define relevant standards for that purpose, i.e. Audio Definition Model (ADM), Serial ADM, the ITU ADM Renderer and further specifications. We …
More open-source for open object-based audio workflows
Last year we released two open-source C++ libraries: libbw64 and libadm. Now that the ITU ADM (Audio Definition Model) Renderer (Recommendation ITU-R BS.2127-0) is published, we are adding another library to the list – the libear. The library is developed in cooperation with BBC R&D and published using the permissive Apache 2.0 license under the …
The EBU ADM Renderer evolved into the ITU ADM Renderer
In previous posts we informed about the progress and achievements related to our Next Generation Audio renderer work, especially about the EBU ADM Renderer or simply the “EAR”. At the last ITU-R WP6C meeting in Geneva, where international standards for production and quality topics in broadcasting are discussed and made, we finally achieved one of …
