HDR-Colour Volume – Colour difference metrics in 3D

Birgit Schmidt-Sodingen — Mon, 15 Mar 2021 08:27:48 +0000

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.

How to get started with the Audio Definition Model

Benjamin Weiss — Thu, 20 Feb 2020 07:30:41 +0000

Audio is on the brink of the next big step after the transition from mono to stereo. Next Generation Audio (NGA) and especially object-based audio will provide the consumer with a lot of new features such as personalizable dialogue level. Check out this EBU website for an introduction into NGA and an overview of the ...

HDR-Colour Volume – Colour Space Visualization in 3D

Birgit Schmidt-Sodingen — Wed, 12 Feb 2020 15:43:00 +0000

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 ...

More open-source for open object-based audio workflows

Benjamin Weiss — Wed, 31 Jul 2019 06:03:57 +0000

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

Michael Weitnauer — Thu, 04 Jul 2019 07:15:45 +0000

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 ...

5G-Broadcast in 3GPP: Where are we?

IRT continues contributing to 3GPP to enhance 5G Broadcast together with the EBU, BBC and a growing number of supporters such as ABS, Bittium, BMWi, British Telecom, Cellnex, CHTTL, Dish, ESA, Enensys, Fraunhofer, Nomor, Nokia, One2Many, Qualcomm, Rohde & Schwarz, Samsung, SJTU, Telstra, UPV/EHU, among others. After our last report (see: https://lab.irt.de/irt-contributes-to-the-studies-in-3gpp-to-enhance-5g-broadcast/) it has rained ...

Transmitting station in Ismaning ready for operation for Bavarian research project “5G TODAY”

Hans Brand — Fri, 22 Mar 2019 10:39:10 +0000

As part of the Bavarian research project 5G TODAY, an LTE/5G test field with the aim to enable the efficient distribution of broadcast signals combined with attractive services in the network of the future is currently being set up in the Bavarian Oberland. Under the lead of IRT, the project partners Kathrein and Rohde & ...

HRADIO: Online demo of transparent DAB(+) distribution over IP

Alexander Erk — Thu, 21 Feb 2019 13:57:19 +0000

Radio is going digital – slowly but steadily. Currently, this happens in two different worlds: One is DAB(+) and the other is IP streaming. DAB(+) is a sophisticated and efficient broadcast standard with many clearly specified add-on functionalities – but it does not support personalisation of its services as is. In contrast, IP-based radio services ...

EBU ADM Renderer Version 1.1 released

Benjamin Weiss — Wed, 05 Dec 2018 14:06:59 +0000

If you are a regular visitor of the IRT Lab, you already know the EBU ADM Renderer (EAR) – a renderer for Next Generation Audio content described by ADM metadata. The specification is published as EBU Tech 3388 and it is accompanied by an open source reference implementation written in the programming language Python. Now ...

IRT contributes to the studies in 3GPP to enhance 5G-Broadcast

Jordi Gimenez — Mon, 26 Nov 2018 09:00:35 +0000

IRT, in collaboration with the EBU and BBC, is engaged in the study to evaluate and potentially enhance LTE-based 5G Terrestrial Broadcasting. We are evaluating this technology so that it can meet requirement for terrestrial broadcasting in static and high-speed environments. The study item description is contained in document RP-181342. During Rel-14, the use cases ...
