Amsterdam Bluetooth demo shows web-based control
A web-based remote controller for a DVD player has provided the first ever demonstration of Internet Protocol version 6 (IPv6) running over Bluetooth wireless technology.
The transmitter is powered directly from the iPod creating no need to charge the unit separately.
The stylish receiver is powered by a 12V DC power supply and features RCA stereo plugs as well as optical S/PDIF and mini-jack output allowing for compatibility with any home stereo.
The BlueTrip is compatible with the 3G and 4G iPods along with the iPod mini and iPod photo.
BlueCore implements a host of profiles including A2DP (Advanced Audio Distribution Profile) and AVRCP (Audio/Visual Remote Control Profile).
AVRCP permits the BlueTrip to act as a remote control unit for a connected Bluetooth device.
The A2DP profile allows advanced audio to be transmitted from the music player to devices such as Bluetooth stereo headphones or a home stereo.
BlueCore3-MM's integrated DSP also means that the device requires no external processor for audio analysis, thus saving money on the associated bill of materials.
The BlueCore3-MM DSP is also more efficient in audio processing, achieving power consumption levels similar to that of Bluetooth mono headsets.
This allows the BlueTrip to have a small impact on the battery life of the iPod and enjoy a longer playing time.
CSR offers a range of standard solutions and technologies for customers designing Bluetooth multimedia products.
CSR's BlueLab 3.2 software development kit allowed Griffin Technologies to take these standard solutions and customise them for their own distinct offering.
The in-built protected user mode, enabled by BlueLab, means that customer software cannot interfere with the Bluetooth operation of the chip.
This protection feature all but obviates the need for retesting.
Mark Rowan, Engineering Manager for Griffin Technologies commented: "Our new BlueTrip device uses the best Bluetooth technology and the highest quality components on the market".
"CSR's expertise has allowed us to achieve the highest possible sound quality and a highly attractive product".
Mark continued: "Thanks to CSR's support, we have been able to introduce Bluetooth connectivity to our iTrip offerings with ease and minimal time to market".
Luke d'Arcy, Product Marketing Manager for CSR commented: "Griffin Technologies demanded the highest Bluetooth audio quality for their BlueTrip".
"CSR was able to offer the most cost-effective, high-performance multimedia silicon and software package on the market".
"Through the use of BlueLab software we were able to offer Griffin a truly customised, leading Bluetooth solution without them incurring increased costs".
