Codian's Conferencing Products Use Fraunhofer IIS Audio Codecs.ERLANGEN, Germany -- High quality audio codecs make video conferences more pleasant to follow: the new generation of Codian's video conferencing equipment, the MCU (1) (MicroController Unit) A computer on a single chip. See microcontroller. (2) (Multipoint Control Unit) A device that is used to moderate a videoconference of three or more end points (users at computers or groups of users 4200 and IP VCR VCR: see videocassette recorder. VCR in full videocassette recorder Electromechanical device that records, stores on a videotape cassette, and plays back on a TV set recorded images and sound. 2200 series, features Low Delay Advanced Audio Coding (audio) Advanced Audio Coding - (AAC) A successor to MP3, allowing lower bit rates and more stable quality. See MPEG-2 AAC Low Profile and MPEG-4 AAC Main Profile. (MPEG-4 AAC-LD) and Low Complexity Advanced Audio Coding (MPEG-4 AAC-LC) from Fraunhofer IIS (Internet Information Services) Microsoft's Web server. IIS runs under the server versions of Windows, adding HTTP server capability to the Windows operating system. . Preserving a natural sound, these codecs The following is a list of codecs. Audio codecs Non-compression formats
The high audio quality provided by MPEG-4 AAC-LD and AAC-LC eliminates any telephone-like feeling from video conference systems and make conferences less exhausting and more pleasant to follow. In addition to natural sounding speech and music, MPEG-4 AAC-LD features a low encoding / decoding latency together with low data rates. All these features make the codec (1) (enCOder/DECoder) A hardware circuit that performs analog-to-digital conversion (ADC) and digital-to-analog (DAC) conversion. When analog signals are entered into a computer, cellphone or other device via a microphone or video source such as VHS tape or analog TV, one of the most important audio coding technologies in today's video conferencing world. MPEG-4 AAC-LD and AAC-LC are used in the Codian MCU 4200 and IP VCR 2200 series. The MCU 4200 series is a conferencing bridge. The IP VCR 2200 series is a digital recorder specifically designed for video conferencing. Harald Popp, head of the Multimedia Realtime Systems department at Fraunhofer IIS, says: "As main developers of the powerful MPEG-4 AAC-LD and MPEG-4 AAC-LC audio standards, we are of course delighted to see that our software makes its way into Codian's video conferencing products." Mark Loney, Director of Product Management for Codian, adds: "We are delighted to work with Fraunhofer to add AAC (Advanced Audio Coding) An audio compression technology that is part of the MPEG-2 and MPEG-4 standards. AAC, especially MPEG-4 AAC, provides greater compression and better sound quality than MP3, which also came out of the MPEG standard. support to our products. This is an important part of our quest to support the best features of every videoconferencing endpoint. AAC allows us to fully interoperate with systems from Tandberg, Sony, LifeSize and VCON." The Fraunhofer-Gesellschaft founded in 1949 is one of the leading organizations of applied research in Europe. It operates 58 national research establishments and numerous international centers. The headquarters are located in Munich, Germany. Most of the 12 700 staff members are scientists and engineers. Founded in 1985 the Fraunhofer Institute for Integrated Circuits IIS in Erlangen, today with 470 staff members, ranks first among the Fraunhofer Institutes concerning headcount and revenues. With the development of the audio coding method MP3, Fraunhofer IIS has reached worldwide recognition. It provides research services on contract basis and technology licensing. The research topics are: Audio and video source coding, multimedia realtime systems, digital radio broadcasting and digital cinema systems, integrated circuits and sensor systems, design automation, wireless, wired and optical networks, localization Customizing software and documentation for a particular country. It includes the translation of menus and messages into the native spoken language as well as changes in the user interface to accommodate different alphabets and culture.
