Washington, September 6 (ANI): German researchers are sure that compression technologies can put an end to the poor images and sound quality that are often encountered by people during video and telephone conferencing sessions.

At this year's IFA international consumer electronics exhibition in Berlin, researchers from four Fraunhofer Institutes will demonstrate the power and flexibility of these new technologies by holding games sessions in which players compete against each other via the Internet.

To ensure high and consistent quality of sound, the researchers have developed the Audio Communication Engine, which consists of reciprocally-tuned components that vastly improve the sound quality and clarity of video and telephone conferences compared with present systems.

The key component in providing excellent sound is the MPEG Enhanced Low Delay AAC audio codec, which ensures low-delay hi-fi quality even at low bit-rates.

An echo control eliminates troublesome echo so that users do not have to wear a headset, and can move around the room freely.

Sophisticated signal processing, which extends from enhancement of the microphone signals through to multi-channel loudspeaker reproduction, removes the barrier of distance between friends without incurring great installation expense.

The researchers say that they have already started working on actual implementation by designing the technology for integration in TV sets, set-top boxes and hi-fi systems.

They claim that visitors to the IFA international consumer electronics exhibition will be able to experience the system's superb picture and sound quality, and even play games such as Memory, Battleships and Sorry. (ANI)
