The early days of VOIP
calling required a lot of patience, as the half-second or more delay between you speaking and your conversation partner receiving often turned the convo into a start and stop mess. Those days are gone for voice, but we're right back there again when it comes to HD video calls. However, random product researcher Fraunhofer
is working on a new device to kill the lag and speed up your two-way monologues. It's basically an encoder card able to do hardware squashing of HD video via H.264 and audio via AAC, not unlike the sort of tech Skype
requires for its SkypeHD
-compatible video cameras. Fraunhofer's tech is also said to remove boomy room echoes and even handle network hiccups to keep you streamin' in style. The result is said to be sub-100ms lag, which would be more or less playable for a shooter. Expect more on this development soon from IFA
Fraunhofer Presents HD Video Conferencing to Deliver Natural Communication Experiences to the Home
Fraunhofer's telepresence@home HD Video Conferencing Technology, Developed within the EU Project "Together Anywhere Together Anytime" Delivers a "Same-Room" Experience Despite the Distance between Users
BERLIN--(BUSINESS WIRE)--Fraunhofer IIS, the world's authoritative source of audio and multimedia technologies, is presenting technologies for telepresence@home and HD video conferencing systems, featuring low-delay, high-quality audio and video for the first time at IFA 2010 in Berlin. Fraunhofer's technology allows users to experience completely natural conversation just as if the participants were sitting in the same room.
"The combination of Fraunhofer's low-delay video technology and Audio Communication Engine will enable truly outstanding video conferencing experiences in the home"
The telepresence@home system demo is part of the European Union's "Together Anywhere Together Anytime" (TA2) project, which aims to enable new media experiences to nurture relationships between families and friends. Through its work as a research partner within TA2, Fraunhofer contributed its Audio Communication Engine to provide the highest quality audio, and now delivers a matching low-delay video solution. This new video technology reduces delay to a level that allows for natural communication experiences. In contrast to conventional video conferencing systems, the Audio Communication Engine and low-delay video technology deliver a complete telepresence@home system that provides the highest audio and video quality along with imperceptible latency.
"Current low-delay video technologies require either a much higher bit-rate or rely on very expensive dedicated hardware," said Dr. Nikolaus Faerber, low-delay video project manager at Fraunhofer IIS. "However, Fraunhofer's solution is based on PC hardware, which is widely available at a very competitive price. The result is an HD video conferencing system for the home that delivers the best possible communication experience at a low cost."
Fraunhofer's low-delay video technology consists of low-delay, high-quality video encoding and decoding based on H.264 in conjunction with a custom designed low-delay frame grabber card. This combination enables high-quality HD video at DSL compatible bit-rates well below 100 ms delay end-to-end.
For audio, Fraunhofer's Audio Communication Engine combines several components that vastly improve the sound quality and clarity of video conferences compared to present systems. First, the MPEG audio communications codec "AAC Enhanced Low Delay" ensures CD-quality audio at very low coding delays and bit rates. Second, robust, multi-channel echo-control software reliably removes echoes, providing hands-free convenience and complete freedom to move around in a room. Finally, a specially matched IP streaming stack and error concealment tools allow for high-quality audio even under adverse network conditions.
"The combination of Fraunhofer's low-delay video technology and Audio Communication Engine will enable truly outstanding video conferencing experiences in the home," said Ian Kegel, Research Group Leader at BT Innovate & Design and Technical Delivery Manager in the TA2 project. "Because the communication is so natural, users feel as if they are in the same room whether they are playing a game, interactively sharing videos or just having a conversation. This same-room feeling means that distance between people no longer impacts the quality of their communication and relationships."
Fraunhofer will demonstrate its technology for PC-based video conferencing at its booth 5/7 at IFA TecWatch (hall 8.1).
