Bluetooth chip is
music to Samsung's ears
Samsung has selected CSR's industry-leading BlueCore silicon and software stack to bring advanced Bluetooth connectivity to its first GSM handsets to offer stereo streaming capability
The SGH-E750 and SGH-E760 use CSR's BlueCore3-ROM (BC3-ROM) and proprietary BlueCore Host Software (BCHS) to offer wireless connectivity with other Bluetooth devices. Both handsets also wirelessly stream MP3 music via Bluetooth to the new generation of Bluetooth stereo headsets, such as Samsung's own SBH100.

The SBH100 headset also uses CSR's BlueCore and, as with standard mono Bluetooth headsets, also enables hands-free voice calls.
The SGH-E750 and SGH-E760 are expected to be available on GSM networks worldwide in Q4 2005.
Both triband handsets follow Samsung's popular sleek clamshell design and integrate 1.3Mpixel cameras.
The SGH-E750 camera also features an integrated flash and the SGH-E760 includes a digital power amp and dual speakers for enhanced audio.
Both handsets also feature new functions such as a digital compass and gesture recognition for enhanced mobile gaming.

By incorporating CSR's BlueCore3-ROM into the SGH-E750 and SGH-E760 handsets, Samsung can not only offer its customers the robust file transfer and handsfree capability of traditional Bluetooth but also the capability to stream MP3 music files wirelessly.
BlueCore3-ROM is currently the only Bluetooth technology to offer native MP3 support, thanks to its internal codec, software and DSP.
These features combine to reduce power consumption of the Bluetooth device as well as reducing the space taken on the circuit board and thus overall bill of materials.
MP3 music streams also offer better audio quality and require lower data transfer rates than the subband coding (SBC) format used by other Bluetooth silicon vendors.
In order to support music streaming and hands-free call handling from a Bluetooth stereo headset, the handsets support the Advanced Audio Distribution Profile (A2DP) and Audio Visual Remote Control Profile (AVRCP), which allows calls and music to be controlled from the headset.
BlueCore Host Software (BCHS) is integrated into the handset to reduce power consumption of the Bluetooth device since it implements all of the Bluetooth lower power modes such as deep sleep, helping to reduce overall device power consumption.
This allows the user to take full advantage of all handset features without draining battery life.
Matthew Phillips, VP Asia commented: 'GSM accounts for more than two-thirds of the world's mobile telecommunications industry and consumers are increasingly demanding access to the latest developments in technology'.
Phillips continued: 'Listening to music with a wireless headset has always been popular with consumers using proprietary technologies for home cinema'.
'As phones now support MP3 music playback, we have brought that flexibility to the mobile phone industry using the universal Bluetooth standard'.
