Interactivity – Immersive sound – Universal delivery: The future of TV audio featured by the MPEG-H Audio Alliance
The audio system developed by the MPEG-H Audio Alliance of Fraunhofer, Technicolor, and Qualcomm allows broadcasters and streaming services to deliver the future of TV audio at comparably low bit rates and in a cost-effective manner. It is based on the MPEG-H Audio standard and is being evaluated for the new ATSC 3.0 TV broadcast standard for the U.S.
The system is designed to work with today’s broadcast equipment. It includes object-based and immersive audio that allows viewers to adjust the sound mix to their preferences and improves the realism of sound. Furthermore it will tailor playback to sound best on a range of devices and environments, providing “universal delivery”.
Fraunhofer Cingo® – An immersive sound experience on mobile devices
With Fraunhofer Cingo your mobile devices become true multidimensional sound theaters. Plug in your earphones or use the built-in stereo speakers for enveloping sound when enjoying movies, games or any other virtual environment.
Not only does Cingo enable an excellent surround sound listening experience over stereo speakers or headphones, it also provides existing stereo content with a more natural and clear sound. What’s more, Fraunhofer Cingo supports rendering of 3D audio content with formats such as MPEG-H that add a height dimension to the sound image with 9.1, 11.1 or other channel configurations as well as object-based audio. In addition, Cingo includes loudness optimization for listening in noisy environments and improves the intelligibility of dialog and commentary.
The Google Nexus family of devices uses Cingo for an enhanced listening experience when playing back content in stereo or surround. Cingo is also part of the Samsung Gear VR, creating the ultimate mobile virtual reality experience by delivering 3D spatial sound that incorporates head movements.
Enhanced Voice Services
Enhanced Voice Services (EVS) is the next-generation 3GPP communication codec designed specifically for Voice over LTE (VoLTE) services. EVS enables phone calls with Full-HD Voice quality, bringing call fidelity up to the same level as today’s other digital media services. Integrating state-of-the-art speech and audio coding technology, EVS removes the limitations of bandlimited, voice-centric codecs previously used in mobile communication. The algorithm enables high quality speech, background music and mixed content with the full audible audio spectrum at unmatched low bit rates. Combined with EVS’ advanced robustness against packet loss, the algorithm results in clear, natural sounding conversations and vastly improved performance of hold music and ring back tones.
EWF, Fraunhofer MultimediaPlayer and TPEG – Explore the latest digital radio applications
Explore the full potential of digital radio applications when you visit Fraunhofer’s booth at this year’s IFA. The new Emergency Warning Functionality (EWF) for Digital Radio Mondiale (DRM) and Digital Audio Broadcasting (DAB/DAB+), is a simple and reliable tool that quickly provides the public with emergency information when disasters and emergencies strike. The EWF technology transmits audio messages in emergency situations, and also provides multi-lingual textual information to assist non-native speakers and hearing-impaired users. In the event of an emergency, EWF-enabled digital radio receivers automatically re-tune to the emergency program or wake up from stand-by mode and broadcast the emergency warning.
Booth visitors will also have a chance to learn more about the Fraunhofer MultimediaPlayer for DAB/DAB+ and DRM. Aside from playing back stereo and DAB surround sound, the software supports program-associated data services such as the Categorized Slideshow. Hybrid applications are possible thanks to Journaline’s Hot-Button feature.
Fraunhofer will also present the TPEG decoder software, a digital radio application providing comprehensive travel and traffic information.
