3D audio or ‘immersive’ audio is a new trend since a few years in the audio R&D domain which promises to improve the listening experience for users significantly. At IRT, we have a room which we use for developing and evaluating 3D audio algorithms and tools for more than 9 loudspeaker-setups, such as the 5.1+4H …
As part of the MediaRoad networking activities led by IRT, project partners EBU and BBC produced a podcast series about the transformation of the media technology environment and what this means in terms of professional journeys: jobs, skills, recruitment, training etc. In a series of experts’ interviews, the following question is addressed: which are the …
Terrestrial Broadcast features have been adopted by the standardisation organisation 3GPP, for the first time, under the so-called LTE eMBMS Release 14. New features such as the possibility of using 100% of the carrier resources to transmit broadcast services, the use of Extended Cyclic Prefix (known as Guard Intervals in terrestrial broadcast standards) that could …
For the growing popularity of video streaming in OTT services, multi-sourced caching solutions can reduce costs, improve performance and avoid vendor lock-in. Data traffic of ARD and ZDF for streaming audio and video content has grown rapidly during the last years. This trend will enforce with the shift from classic linear TV to VoD streaming …
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 …
IRT has developed a concept which allows HbbTV apps of different broadcasters to push links to websites or mobile apps to companion screens. These may provide additional information on a show, which viewers can retrieve during or after. A prototype app called Universal Launcher was developed by IRT to showcase the posibilities. Communication between the HbbTV …
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 …
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 …
IP-based broadcast production has long been a hype. Now it is becoming a reality with more and more equipment on the market. But users need interoperable standardized products they can trust. So IRT’s goal is to support the broadcasting market to develop and offer such IP-based products. The technologies required for this, e.g. SMPTE ST …
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 …
