CSR's BlueCore3-Multimedia tech powers GG Telecom headset

Wireless communications specialist CSR confirmed that its BlueCore3-Multimedia is the technology behind the GGBlu stereo headset of GG Telecom.

According to CSR, BlueCore3-Multimedia's inherently low-power architecture enables the GGBlu stereo headset up to 13h of music playback from a 70-minute charge. Developed specifically for music applications, BlueCore3-Multimedia has a single-chip design that incorporates a DSP, which not only provides the processing power necessary for high quality voice but also supports native music formats such as MP3, WMA and AAC. Because BlueCore3-Multimedia has native support for these important stereo CODECs, it no longer transcodes an audio file to or from the sub-band coding, the standard format used by other Bluetooth solutions. CSR shared that this preserves sound quality and minimizes processor bandwidth usage that affects power consumption.

Recognized at the CES 2006 Design and Innovation Awards, the BlueCore-powered GGBlu can be used as a wireless stereo headset for music streaming, a mono headset for handsfree calling and while charging, and an HCI dongle for file transfer from a non-Bluetooth-enabled computer. It can be paired with up to eight Bluetooth devices and can maintain simultaneous links with both a mobile phone and a stereo audio source such as a PC or MP3 player.

When a call is received, the BlueCore3-Multimedia technology and GG Telecom's customized 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.

"Bluetooth stereo headsets have always been considered a logical evolution for Bluetooth technology, given the incredible popularity of mobile music," said Sebastian Koh, CSR vice president for Asia Pacific sales. "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," he added.

CSR claims that its BlueCore line is used in over 50 percent of all Bluetooth devices shipped and over 60 percent of all qualified Bluetooth-enabled products and modules listed on the Bluetooth website.
