Harmonic Expands Multiscreen Video Delivery Capabilities With ProStream™ 4000 Enhancements

Carrier-Grade Transcoding Platform Offers Improved Scalability and Video Quality, and Integration With Leading DRM and CDN Platforms to Enhance Over-The-Top and Mobile TV Services

SAN JOSE, Calif. - Harmonic Inc. (NASDAQ: HLIT) today announced enhancements to its carrier-grade ProStream™ 4000 multiscreen transcoder optimized for adaptive streaming applications that enable operators to meet growing demand for OTT and mobile TV services, while improving the video viewing experience. New capabilities include increased scalability, premium H.264 video encoding, multi-encapsulation, and expanded compatibility with a range of content distribution networks (CDNs) and digital rights management (DRM) software. This solution is easily integrated into existing video infrastructures, and can be controlled and monitored through Harmonic’s NMX Digital Service Manager™.

To manage the complexity of multiscreen and OTT applications, ProStream 4000’s high-density configuration now supports the simultaneous processing of up to 48 video inputs and 48 legacy mobile phone, 18 iPhone®, 12 SD, or four transcoded HD video outputs per single rack unit (1-RU). The ProStream 4000’s new built-in multi-encapsulation feature enables operators to encode once and encapsulate to a variety of target video formats, such as Apple® HTTP Live Streaming, Microsoft® Smooth Streaming, and Adobe® HTTP Dynamic Streaming, as well as multi-bitrate transport streams for NDS and Widevine Adaptive Streaming.

Video quality is enhanced thanks to Harmonic’s expertise in H.264 compression, including implementation of LookAhead™ and VBR technology enhancements specifically engineered for adaptive streaming delivery. Additionally, the ProStream 4000’s new multimachine synchronization capabilities improve the HD multiscreen viewing experience.

“Harmonic continues to enhance its solution offerings that enable service providers and content creators to meet the growing demand for Internet and mobile video services,” said Thierry Fautier, senior director, convergence solutions at Harmonic Inc. “Our award-winning ProStream 4000 is a powerful, versatile solution for live transcoding to multiple screens, with support for a variety of ecosystems, and includes technology advances that effectively address streaming quality to significantly enhance Internet and mobile TV services.”

Harmonic has extended the flexibility of ProStream 4000 through integration with industry-leading CDNs for a variety of adaptive streaming and legacy protocols. A new open Key Management System (KMS) interface allows operators to connect to multiple DRM systems. The ProStream 4000 also boasts improved carrier-grade management capabilities through support for N+M redundancy and Harmonic’s NMX software for network monitoring and control.

Since its introduction, the ProStream 4000 has been successfully deployed for new Internet and mobile TV services by leading satellite, telco, cable, and broadcast operators in North America; major cable, telco, and mobile operators in Europe; and a key CDN operator in the Middle East.

The ProStream 4000 will be on display at Harmonic’s stand 85 during the IP&TV World Forum taking place March 22-24 in London. The ProStream 4000 will also be on display as part of Harmonic’s comprehensive range of video distribution and delivery solutions at the 2011 NAB Show in Las Vegas, April 11-14, in booth SU4909.
