AUSTIN, Texas – November 7, 2000 – Cirrus Logic, Inc. today announced that it has signed a letter of intent with IndigoVision Group plc. to jointly develop real time networked video capability for Cirrus Logic’s industry leading Maverick product line.

The jointly developed integrated circuits and software will enable deployment into a broad range of embedded consumer applications over the next two years, such as digital TVs, handheld devices, set-top boxes, video replay boxes, video servers and closed circuit TVs. In addition, the new video products will further enhance portability and mobility of industrial applications in the security and surveillance markets.

IndigoVision has developed five generations of VideoBridge® technology, a complete set of hardware and software IP Video (IPV) enabling solutions. VideoBridge combines all the elements of visual communications into one fully integrated suite of technology: video acquisition, compression, transmission, analysis, recording, administration and viewing.

“This is a logical progression of the Maverick chip’s leadership in Internet connectivity,” says Scott McDonald, vice president of marketing for Cirrus Logic’s Embedded Processors Division. “As broadband access proliferates over the next two to three years in the consumer marketplace, we envision a demand for real-time video just as there is for MP3 audio today. This new development is timed to take advantage of that convergence.”

“The addition of high quality, real time video to the Maverick chip is a natural extension of our business model and Maverick’s audio leadership,” adds Matthew Perry, vice president and general manager of Cirrus Logic’s Embedded Processors Division. “That same experience will also give us the opportunity to take our knowledge of audio content distribution and security and apply it to video.”

“This deal is a landmark for the Internet Protocol Video (IPV) technology industry,” says Sergio Tansini, IndigoVision’s Chief Operating Officer. “The agreement with Cirrus Logic will offer product designers a unique opportunity to enable full frame, real time, audio-visual communications for Internet and telecommunications applications and will change the way the world communicates.”
