CSR's BlueCore with DSP Architecture Adds MP3 Support to GGBlu Headset Advanced Lower Power Bluetooth for GG Telecom's Award-Winning Stereo Headset.CAMBRIDGE, England -- CSR PLC (LSE LSE - Language Sensitive Editor :CSR (1) (Customer Service Representative) A person who handles a customer's request regarding a bill, account changes or service or merchandise ordered.

GGBlu can be used as a wireless stereo headset for music streaming, a mono headset for handsfree calling and while charging, an HCI (Human Computer Interaction) Refers to the design and implementation of computer systems that people interact with. It includes desktop systems as well as embedded systems in all kinds of devices. dongle The term was originally slang for a "hardware key." Today, the term is often used to refer to any small adapter that has a short cable with connectors at both ends. See hardware key and PC Card dongle. for file transfer from a non-Bluetooth-enabled computer. Supported by the inherently low-power BlueCore3-MM architecture, the GGBlu, which was officially launched at CeBIT in Germany, claims a maximum of 13 hours of music playback from only a 70 minute charge. Presented in an innovative design which caught the eyes of the CES 2006 Design and Innovation Award judging panel, the GGBlu can pair with up to eight Bluetooth devices and maintain a simultaneous link with both a stereo audio source such as a PC or MP3 player and mobile phone. When a call is received, the BlueCore3-Multimedia technology and GG Telecom's customised firmware inside the GGBlu will pause music playback, allowing the user to accept the call at the touch of a button, and resume music playback once the call is complete. "Consumers are demanding increasing levels of functionality from their gadgets and Bluetooth headsets must now serve more than a handsfree, mono purpose," noted Lisa Tian of GG Telecom. "Bluetooth headsets must offer all their previous functions to a high standard as well as facilitating new applications such as stereo audio, while continuing to satisfy the fashion criteria of consumers. These different aspects required an advanced level of Bluetooth engineering and expertise which we found with CSR." CSR developed BlueCore3-Multimedia with stereo music applications in mind. The single-chip design incorporates a DSP (1) (Digital Signal Processor) A special-purpose CPU used for digital signal processing applications (see definition #2 below). It provides ultra-fast instruction sequences, such as shift and add, and multiply and add, which are commonly used in math-intensive which not only provides the processing power necessary for high quality voice but which also supports native music formats such as MP3, WMA (Windows Media Audio) An audio compression method from Microsoft. Known originally as MSAudio, this proprietary format competes with the MP3 and AAC methods. WMA encodes rapidly and is known to be especially effective at low bit rates. and AAC. By supporting these native music formats, the DSP removes the need to transcode (1) To convert from one format to another. It implies conversion between very distinct kinds of data, such as from speech into text or from analog video into digital frames. Sometimes the term is used as nothing more than a fancier synonym for "convert. the audio files to or from the standard sub-band coding (SBC) format used by certain Bluetooth solutions for stereo audio streaming. The act of encoding and then decoding MP3 files to and from SBC leads to a loss of sound quality as well as requiring high levels of processor bandwidth leading to higher levels of power consumption. CSR's BlueCore offers native support for these important stereo CODECs. "Bluetooth stereo headsets have always been considered a logical evolution for Bluetooth technology, given the incredible popularity of mobile music," explained Sebastian Koh, VP Sales Asia Pacific, for CSR. "However, it has taken a few years to perfect the technology which ensures the highest quality audio as well as the simultaneous link between music device and mobile phone to prevent the irritation of missing a call. Once this was achieved in 2005, device manufacturers have created new products to encompass this basic concept, which will satisfy consumers' lust for both performance and design." About CSR CSR plc is the leading global provider of Bluetooth technology and has developed expertise in other single-chip wireless communication standards such as Wi-Fi (IEEE (Institute of Electrical and Electronics Engineers, New York, www.ieee.org) A membership organization that includes engineers, scientists and students in electronics and allied fields. 802.11). CSR offers developed hardware/software solutions for Bluetooth based around BlueCore, a fully integrated 2.4 GHz radio, baseband and microcontroller. CSR has now launched its fifth generation BlueCore suite and is in volume manufacture of its fourth generation BlueCore devices. BlueCore4 supports the Enhanced Data Rate (EDR (Enhanced Data Rate) An acronym occasionally used to reflect an advancement in transmission or transfer speed. For example, Bluetooth 2.0 + EDR provides a dramatic increase in speed over the previous version. See Bluetooth. ) standard, which was ratified at the end of 2004. BlueCore4 remains the only EDR silicon to be shipping in volume today. In November 2004 CSR launched UniFi, the first single chip 802.11a/b/g embedded solution specifically targeting the mobile phone and consumer electronics markets. BlueCore features in over 50 per cent of all Bluetooth devices shipped and over 60 per cent of all qualified Bluetooth enabled products and modules listed on the Bluetooth website with industry leaders including Nokia, Dell, Panasonic, Sharp, Motorola, IBM, Apple, NEC (NEC Corporation, Tokyo, www.nec.com, www.necus.com) An electronics conglomerate known in the U.S. for its monitors. In Japan, it had the lion's share of the PC market until the late 1990s (see PC 98). NEC was founded in Tokyo in 1899 as Nippon Electric Company, Ltd. , Toshiba, RIM and Sony using BlueCore devices in their range of Bluetooth products. In March 2005, CSR acquired Clarity Technologies Inc., for its Clear Voice Capture (CVC See CSC. ) technology that enhances the audio performance of any voice-based product or system. Applications for CVC include wireless headsets, handsets and automotive hands free systems. In August 2005, CSR completed the acquisition of UbiNetics' software business, providing a strong R&D team to accelerate its existing software development in Bluetooth, Wi-Fi and UWB. The UbiNetics team gives CSR the capacity to extend its offering to mobile handset customers. CSR has its headquarters and offices in Cambridge, UK, and offices in Japan, Korea, Taiwan, China, India, France, Denmark, Sweden and both Texas and Detroit in the USA.
