La Freebox supporte le DTS Neural

Suite à l’annonce du partenariat en Avril 2012 avec DTS, Free annonce la prise en charge du DTS Neural Surround, un procédé qui permet de profiter d’un son 5.1 qui est transporté au sein d’un flux stéréo matricé LtRt et qui doit être spécifiquement traité en amont et à la diffusion : « pour un débit équivalent, les chaînes et portails de VOD pourront désormais proposer du son en HD 5.1 ». Notez que la Freebox n’est pas la première à inclure cette technologie puisque la Bbox Sensation de Bouygues Telecom propose déjà cela depuis septembre 2013. Quels contenus sont concernés ? A priori, sur Freebox, le DTS Neural sera mis à contribution exclusivement pour la VOD.

Fraunhofer Innovation Enables Cinema-Quality Surround Sound on Google Nexus Devices

Fraunhofer Cingo brings unrivaled surround sound experience to Nexus 7 and Nexus 10 users

Theater quality surround sound in the palm of your hand is now a reality for Nexus 7 and Nexus 10 users thanks to Fraunhofer Cingo, the newest innovation from the world renowned experts in audio and multimedia technologies. Fraunhofer IIS developed Cingo to achieve significantly enhanced playback of stereo and surround sound on mobile devices. With Cingo, built-in stereo speakers or headphones will deliver the high-quality surround sound consumers have come to expect from their home theater systems. The first device to natively integrate Cingo is Nexus 7, announced earlier today at the Google press event. For the Nexus 10, Fraunhofer Cingo will be available through a software update.

Cingo dramatically improves the entertainment experience on mobile devices. It allows for a complete immersion into a film’s sound in the same way that multi-channel audio systems do in cinemas. Furthermore, Cingo delivers natural and clear sound even in the noisiest environments.

“Owners of the Nexus 7 and Nexus 10 will be surprised that this improvement in quality was possible on handheld devices without compromises to the form factor and usability,” said Harald Popp, head of the business department at the Audio and Multimedia division of Fraunhofer IIS. “When paired with HD video quality, Cingo transforms mobile devices into personal movie theatres that fit into a pocket.”

The efficient delivery of surround sound to mobile devices is made possible by the High Efficiency AAC (HE-AAC) audio codec technology. HE-AAC was co-developed by Fraunhofer IIS and is today’s most efficient high-quality surround and stereo audio codec. Android phones and tablets natively support HE-AAC Multichannel and in combination with Cingo, they become true entertainment centers while on the move or at home. To capitalize on the new capability, Google will now offer feature films with surround sound on the Nexus 7 using HE-AAC Multichannel. These titles can be played using Cingo via headphones, internal stereo speakers or with an HDMI output to home theater surround systems.

Cingo is available from Fraunhofer as a product-ready software implementation for mobile device manufacturers, chip set vendors and providers of multimedia services. Fraunhofer IIS will demonstrate Cingo and HE-AAC on the Nexus 7 and Nexus 10 at IFA, hall 11.1, in Berlin, September 6 -11, and at IBC, booth 8.B80, in Amsterdam, September 13-17.

About Cingo

Fraunhofer Cingo creates a realistic surround sound impression when listening to surround content over stereo speakers or headphones. Based on the latest developments in audio technology, Fraunhofer Cingo contains a complete set of tools to deliver an exceptional level of audio quality, unmatched on mobile devices.

With the virtual surround sound mode each audio channel is presented as a virtual sound source in such a way that it is heard from a specific location and distance, for example a loudspeaker of a 5.1 surround setup in a living room. This enables the playback of stereo or surround sound over the built-in speakers or any type of headphones with an authentic surround effect.

The loudness optimization feature of Cingo delivers a natural and clear sound even in the most challenging situations. Together with the equalizing algorithm, which compensates for the common audio quality deficiencies often encountered with smartphones and tablets, Fraunhofer Cingo ensures significantly improved audio quality in any listening situation.

Google selects HE-AAC Multichannel from Fraunhofer IIS for Google Play Movies in Surround

Android users to enjoy Google Play movies in cinema-quality surround sound at home or while on the go.

Google and Fraunhofer IIS deliver the first movies with a true 5.1 channel surround sound experience from Google Play. The immersive sound quality consumers have come to expect from TV, Blu-ray disc or DVD is now available with movies streamed or downloaded from Google Play directly to their Android devices running 4.1 or later. Google chose HE-AAC Multichannel as Android’s only surround sound codec due to its open-standard nature and excellent bit-rate efficiency.

When connected to a surround sound system and TV with an HDMI cable, Android users will be able to play high quality audio and video from their smartphones and tablets in surround. On the go, Android devices will play movies in great stereo quality and selected Nexus products will also include the Fraunhofer Cingo virtual surround rendering technology, which will play movies in realistic surround sound on earphones or tablet stereo speakers.

Android’s HE-AAC Multichannel implementation includes full support for loudness and downmix metadata commonly known from the broadcast TV world, as well as other features that allow the sound to be tailored for an optimum user experience in any listening mode and environment.

“Google Play movies in 5.1 HE-AAC Multichannel sound are the first realization of our vision of bringing true theatrical surround sound to mobile devices,” said Robert Bleidt, Division General Manager at Fraunhofer USA Digital Media Technologies. “The Google and Fraunhofer partnership creates a tremendous value for consumers by offering one format that delivers a high quality experience both in-home and while mobile. Consumers may experience surround sound over headphones while on their way home from work, and finish the movie in true, exciting surround in their living room,” he added.

HE-AAC Multichannel is part of the Fraunhofer FDK AAC codec library for Android since version 4.1 and a required feature of all Android-compatible devices. This software makes open-source Fraunhofer implementations of the MPEG audio codecs AAC, HE-AAC, HE-AACv2, and AAC-ELD available to the Android community.

HE-AAC is today’s most efficient high-quality surround and stereo audio codec deployed in over 5 billion devices and used in TV, radio, and streaming services worldwide. The codec is natively integrated into most operating systems, streaming platforms and consumer electronics devices. In addition to its unique coding efficiency, HE-AAC has the dynamic ability to change audio bit-rates seamlessly in order to adapt to changing network conditions as consumers stream content to a variety of devices. It can be used with any adaptive streaming technology including MPEG-DASH, Apple HLS, Adobe HDS and Microsoft Smooth Streaming.
