CSR Debuts aptX Low Latency Codec for Synchronised Audio and Video

aptX Low Latency opens new opportunities in video and gaming markets for CSR

IFA 2012, BERLIN, Germany - Aug 31, 2012 - CSR plc (LSE: CSR; NASDAQ: CSRE) today unveiled CSR aptX Low Latency, a new audio coding technology that slashes to one-third the delay, or latency, of stereo audio signals over Bluetooth® connectivity, effectively enabling consumers to watch video while listening to wireless audio in a synchronised fashion. As a result, the product is ideally suited to wireless audio delivery for video and gaming applications – opening expansive new market opportunities for CSR.

CSR aptX Low Latency for Bluetooth offers a coding delay of just 32 milliseconds (ms) – far less than the standard Bluetooth latency of more than 150 ms, and well under the 45 ms recommended latency for audio/video applications.

“The new aptX Low Latency technology presents an opportunity for CSR to standardise Bluetooth wireless connectivity for audio-visual and gaming applications,” said Anthony Murray, Business Group SVP of CSR. “The potential size of these new markets is much bigger than the audio-only market, and gives manufacturers of wireless audio equipment the opportunity to capitalize on the exploding demand for connectivity for gaming, audio/video for mobile devices, and television – without compromising on the quality of the end-user experience.”

Although standard Bluetooth technology offers the ability to stream stereo audio wirelessly from mobile handsets and other audio playout devices to headphones and speakers, its bandwidth-constrained audio poses inferior sound, and the latency delay is not suitable for video or gaming applications. CSR aptX audio coding technology is designed to solve both the bandwidth and latency barriers, delivering CD-quality sound wirelessly over Bluetooth connections for a variety of consumer electronics applications – now including video and gaming. CSR aptX Low Latency is now available for license on CSR audio platforms and on Android® OS.

CSR aptX is now deployed by consumer electronics giants including Samsung, Motorola, HTC, Nokia, Monster, and Sennheiser, among many others.
