ORLANDO, Fla.--(BUSINESS WIRE)--March 18, 2002

CSR (Cambridge Silicon Radio) has demonstrated the ability of a standard low-cost Bluetooth link to handle 25fps (frames per second) streaming video and audio.

This is believed to be the world's first demonstration of Bluetooth supporting VHS quality video and offering a low-cost option for bringing wireless streaming video to the mass market.

CSR is transmitting Microsoft Windows Media Format and MP3 files received by a Bluetooth-enabled Notebook PC powered by CSR BlueCore technology. A PDA or other similar Bluetooth-enabled device could just as easily be used to receive the Bluetooth signal without compromising the resolution. Under ideal conditions, even higher resolution is possible with Bluetooth.

The lower cost, lower power consumption, smaller size and wider adoption of Bluetooth in portable, consumer devices means that it offers a very practical and cost effective way of enabling wireless transmission of streaming video and audio for many applications.

As websites become increasingly media-rich, there is a need for browser-enabled devices to be able to view the video and audio files. Consumers expect that in selecting a wireless connection to the Internet, that speed and quality will not be compromised when compared to a wired link.

Eric Janson, vice president CSR North America, commented, "This is an exciting development which clearly shows the massive potential of Bluetooth. In addition to the many and varied applications we are already seeing, Bluetooth has a massive untapped potential and CSR is at the forefront of exploiting this potential."

The company's mission is to create the most highly integrated radio devices available, fabricated using standard CMOS technology, to provide its customers with the lowest cost of ownership of high quality digital radio.

CSR was the first company in the world to offer a true single-chip Bluetooth solution with BlueCore, a fully integrated 2.4 GHz radio, baseband and microcontroller. In Q4 2001 CSR released BlueCore2, its second generation family, and offer developed hardware/software bundles for each of the fastest growing Bluetooth applications markets. Users can combine the chips with the CSR Bluetooth software stack to provide a fully compliant solution for data and voice communications or, used with an upper layer host software stack, CSR is able to offer a complete Bluetooth end-to-end solution.

CSR has a growing list of major international companies including Sony, Compaq, IBM, Fujitsu, LG, ALPS, TDK, 3Com, Mitsumi, Siemens and Motorola, who have already used CSR's BlueCore in the development of a range of Bluetooth products. In fact, up to the end of 2001, 70% of available pre-qualified modules, as listed on the qualified products page of the Bluetooth Special Interest Group (SIG) web site, feature BlueCore01 and it is in 60% of all qualified Bluetooth v 1.1 enabled end product designs.

CSR is headquartered in Cambridge, UK, with offices in Richardson, Texas; Tokyo, Japan; Singapore and Aalborg, Denmark.
