Fraunhofer IIS Presents Next Generation Video Telephony on SmartTVs with Full-HD Voice at IFA 2012

Press Release /

Fraunhofer’s AAC-ELD audio codec software to provide high-quality communications in living rooms through TV sets and set-top boxes.

BERLIN – Aug. 31, 2012 – IFA Hall 11.1/10 – Fraunhofer Institute für Integrated Circuits IIS, the world’s renowned source for audio and multimedia technologies, presents next generation video telephony on SmartTVs at IFA 2012. The audio codec Enhanced Low Delay AAC (AAC-ELD) delivers CD-like audio quality for an unrivaled communication experience, paving the way of SmartTVs as primary communication devices in the living room.

AAC-ELD is the only widely adopted Full-HD Voice technology. Full-HD Voice is the future quality standard for audio communication, taking it to a new dimension. For the first time, phone calls sound as natural and clear as talking to a person in the same room.

At IFA TecWatch in Hall 11.1, visitors of the Fraunhofer booth can now experience how video calls on SmartTVs can be improved by the implementation of AAC-ELD. The presentation at IFA evolved from the ongoing EU project Vconect. In this project capabilities are developed that will allow ad-hoc groups of people to enjoy real-time high-quality audio-video communication.

»Thanks to our AAC-ELD software, communication apps for SmartTVs will allow for conversations at a level of audio quality which so far has been limited to high-end video conferencing or telepresence systems«, says Harald Popp, head of the Multimedia Realtime Systems department at Fraunhofer IIS. »As AAC-ELD is already part of all leading smartphone operating systems including iOS and Android, it is high time to finally introduce Full-HD Voice quality to the living room.«

Full-HD Voice is the highest audio quality standard for communication applications. Whereas legacy telephony is restricted to an upper limit of 3.4 kHz audio bandwidth, Full-HD Voice capable audio codecs support audio bandwidths of 14 kHz and more which covers the full audible audio bandwidth. Consequently, only Full-HD Voice audio codecs, such as AAC-ELD, can provide a realistic communication experience just like a conversation in the same room.

AAC-ELD is a communication codec based on the commonplace music codec AAC which is used by major music download and streaming platforms. AAC-ELD provides CD-like audio quality for video and telephone calls at very low bit-rates. Thus, most professional video conferencing, telepresence systems as well as consumer video telephony applications such as Apple FaceTime® rely on AAC-ELD.
