The globally-renowned telepresence provider has implemented the technologies in its revolutionary new 6G platform.
Leading research and development organisation the Fraunhofer Institute for Integrated Circuits IIS has announced that it has licensed two of its cutting-edge audio technologies to Teliris, the leading telepresence provider. The global company is implementing Fraunhofer's Acoustic Echo Control and MPEG AAC-LC audio codec into its telepresence 6G solutions.
Unveiled at InfoComm 2009, Teliris 6G Telepresence enables the delivery of high-quality telepresence over general purpose networks, thereby reducing acquisition, deployment and operating costs. As part of this significant new platform, Teliris has integrated two core Fraunhofer technologies to ensure superlative audio quality, system interoperability and standards compliance.
The first of these technologies, Acoustic Echo Control, was developed to tackle the echoes that arise from acoustic couplings between the loudspeakers and microphones of telecommunication devices. The Fraunhofer technology allows the frequency spectrum of the microphone to be modified so that the undesired echo components from the signal transmitted to the far-end are completely inaudible.
The second technology, MPEG AAC Low Complexity (AAC-LC), was co-invented by Fraunhofer IIS and enables excellent audio quality at low bit-rates. AAC-LC has been incorporated into mobile music players, communication devices and digital broadcasting standards, with high-profile adopters including Apple iPod/iTunes and Japanese ISDB broadcasting.
Steven Gage, Executive Vice President and co-founder of Teliris, commented: "Teliris is pleased to integrate the latest AAC-LC codec and Echo Cancellation technologies across our telepresence 6G platforms, ensuring our systems are standards-compliant and widely interoperable. This newest partnership further highlights our continued progress in maintaining the leading market position in the telepresence industry."
Harald Popp, head of the Multimedia Realtime Systems department at Fraunhofer IIS, also welcomed the new association: "Teliris' decision to integrate our advanced audio technologies in its leading telepresence systems, including the acclaimed 6G, provides further confirmation that our work on perceptual coding and processing of audio signals meets the demands of high quality products. Our goal is a highly compelling and realistic sound experience, and Teliris' exciting telepresence products are a fine example of this."
