Coding Technologies' aacPlus Called 'A Clear Winner' by World's Largest Professional Broadcasting Association -- The European Broadcasting Union.Business Editors MOUNTAIN VIEW, Calif.--(BUSINESS WIRE)--Oct. 9, 2002 Spectral Band Replication (audio, compression) Spectral Band Replication - (SBR) Guessing the nontransmitted higher frequency range of a compressed audio file by some helper bits (transmiited with the stream) and the transmitted base band. (SBR SBR - Spectral Band Replication ) Given Credit for Overall Improvement of Codec Performance Coding Technologies, the industry's leading provider of audio compression technologies for the mobile, digital broadcasting and Internet markets worldwide, announced today that the European Broadcasting Union “EBU” redirects here. For other uses, see EBU (disambiguation). The European Broadcasting Union (EBU; French: L'Union Européenne de Radio-Télévision ("UER") (EBU EBU European Broadcasting Union EBU English Bridge Union EBU Enterprise Backup Utility (Oracle 7) EBU European Boxing Union EBU European Board of Urology EBU Electronic Business Unit EBU Equivalent Billing Unit EBU Engine Build Unit ) Subjective Listening Tests on Low Bitrate Audio Codecs shows aacPlus(TM) from Coding Technologies to be the highest quality codec for streaming audio applications. Calling aacPlus "a clear winner," the report states that it is now possible to provide excellent quality stereo audio programming at 48Kbps. The EBU report also credits Coding Technologies' Spectral Band Replication (SBR) (TM) technology with the significant improvement in codec performance compared to the previous report completed in 2000. aacPlus is the combination of MPEG (Moving Pictures Experts Group) An ISO/ITU standard for compressing digital video. Pronounced "em-peg," it is the universal standard for digital terrestrial, cable and satellite TV, DVDs and digital video recorders (DVRs). 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. and Coding Technologies' SBR (Spectral Band Replication) technology. SBR is a unique bandwidth extension technique, which enables audio codecs to deliver the same quality at half the bit rate. As a result, aacPlus delivers CD-quality stereo at 48 kbps. This level of efficiency fundamentally enables new applications in the markets of mobile and digital broadcast. Introduced as the new MPEG 4 Audio reference model in 2001, aacPlus is on track to become a core component of MPEG 4 Audio. "aacPlus is a key component of the XM sound," said XM Executive Vice President Steve Gavenas. "The technologies that define XM Satellite Radio's sound quality have been auditioned and endorsed by leading audio experts from around the world, and it's exciting to learn of this latest affirmation from EBU." "aacPlus delivers CD-quality stereo sound at 48Kbps," said Martin Dietz, CEO (1) (Chief Executive Officer) The highest individual in command of an organization. Typically the president of the company, the CEO reports to the Chairman of the Board. and President of Coding Technologies. "This breakthrough, coupled with our pending adoption by MPEG 4, means that aacPlus is the sweet spot for mobile, digital broadcast, and Internet audio." The EBU tests were conducted in parallel at three sites, BBC BBC in full British Broadcasting Corp. Publicly financed broadcasting system in Britain. A private company at its founding in 1922, it was replaced by a public corporation under royal charter in 1927. , NRK and IRT, ensuring reproducible results. Tests were conducted by groups of expert listeners. The selection of source material featured a range of different audio types covering both speech and music content. There were eight audio codecs under test: Microsoft Windows Media 8, MPEG AAC, aacPlus, mp3PRO, RealNetworks Real Audio 8 and AMR Wideband. The second best codec in the test was mp3PRO, the designated successor of MP3, also developed by Coding Technologies and licensed through Thomson Multimedia. About the European Broadcasting Union Founded in February 1950, the European Broadcasting Union is the largest professional association of national broadcasters in the world with 71 active members in 52 countries of Europe, North Africa and the Middle East and 45 associate members in 28 countries further afield. Activities include operation of the Eurovision and Euroradio networks, coordination of news and sports programming, promotion of technical standardization, legal advice, and the defense of public service broadcasting.
