Palmetto Rural Telephone Cooperative Chose ProStream™ 1000 with ACE™ for its Density, Scalability, Power Efficiencies and Video Quality

Harmonic Inc. (NASDAQ: HLIT) today announced that Palmetto Rural Telephone Cooperative (PRTC) of Walterboro, S.C., has selected the Harmonic ProStream™ 1000 with ACE™ high-density, real-time transcoder to power HD and SD video for its 290-channel IPTV service, based on the Microsoft Mediaroom platform.

“It would have taken over a dozen devices from other vendors to provide the breadth of functionality found in the one rack unit ProStream 1000 with ACE,” said Tony Stout, CTO, at Palmetto Rural Telephone Cooperative. “Harmonic’s ProStream with ACE technology gave us a cost-effective, highly flexible solution that delivers excellent video quality for our Mediaroom deployment, helping us gain a competitive advantage.”

The ProStream 1000 with ACE “any-to-any, any-to-many” real-time transcoding solution provides PRTC with Microsoft picture-in-picture (PIP) capability and support for HD and SD, MPEG-2 and MPEG-4 AVC (H.264) video and audio transcoding of up to 20 HD or 60 SD channels in a compact and power-efficient one rack unit (1 RU) chassis. The platform’s industry-leading density enables PRTC to meet the growing demand for digital TV services.

“Harmonic is working with a diverse group of service operators on numerous deployments to provide high-quality, bandwidth-efficient IPTV video services,” said Chris White, manager of telco sales in North America for Harmonic Inc. “We were able to leverage this extensive experience to provide PRTC with a powerful, efficient solution that can easily scale with their business needs.”

A Microsoft Mediaroom ecosystem partner, Harmonic powers the video headends for a majority of Microsoft’s IPTV customers. Harmonic currently delivers over 13,000 IPTV channels around the world and counts more than 100 telco operators as its customers. The ProStream 1000 with ACE will be on display at Harmonic’s booth #533 during TelcoTV 2011 in New Orleans, Oct. 25-27.
