Market-leading Compression and Transcoding Platforms Enable Picture-in-Picture and Content Delivered in Various Formats for Multi-Screen Services

Harmonic Inc. (NASDAQ: HLIT) today announced that its award-winning Electra® 8000 multi-channel HD/SD universal encoder and ProStream™ 4000 real-time multi-screen transcoder have completed compliance testing for the Microsoft Mediaroom Internet Protocol TV (IPTV) platform. The test for both systems was administered by Microsoft Corp. as part of the Microsoft Mediaroom Interoperability and Qualification Lab (IQ Lab) program, which is intended to enable the ongoing interoperability and compliance of headend equipment used in deployments of Microsoft Mediaroom. Harmonic powers the video headend infrastructure for a majority of Microsoft Mediaroom customers worldwide.

Microsoft Mediaroom enables unique connected TV features and experiences, such as simultaneous recording of multiple high-definition and standard-definition TV channels, personal media sharing, whole-home and remote digital video recording (DVR), and multiple picture-in-picture (PIP) scenarios. The award-winning platform is delivering connected TV experiences to more than 4 million subscribers worldwide.

Service providers that want to deploy Mediaroom-based IPTV services using an existing headend infrastructure can benefit from the real-time transcoding capabilities of the ProStream 4000 platform to generate up to 46 PIPs in one rack unit from MPEG-2 or MPEG-4 AVC (H.264) IP sources. Operators can also benefit from a more integrated and more efficient network with the best-in-class Electra 8000 multi-channel encoder, which supports HD/SD video delivery with simultaneous secondary output for PIP and converged multi-screen applications.

“Harmonic’s Electra 8000 platform offers high quality, bandwidth-efficient HD and SD video, coupled with multi-format, multi-channel capabilities. This versatile system, as well as Harmonic’s support for picture-in-picture with the ProStream 4000 from any IP input, can help facilitate migration to Mediaroom for service providers,” said Jonathan Usher, Marketing Director for the Media Platforms Business at Microsoft.

“A wide range of Harmonic’s video processing systems have been certified as compliant for Mediaroom, meeting the evolving compression and transcoding needs for any IPTV service provider,” said Thierry Fautier, Senior Director of Converged Solutions at Harmonic Inc. “We have worked with Microsoft on numerous deployments to ensure high quality, bandwidth-efficient video for IPTV services, and the Electra 8000 and ProStream 4000 are highly flexible and efficient solutions for IPTV operators choosing to deploy Mediaroom.”

The Electra 8000 is the industry’s most feature-rich and flexible platform, with support for a broad range of output formats for broadcast and converged multi-screen applications, as well as integrated statistical multiplexing, broadcast quality up/down-conversion, integrated audio leveling and other unique capabilities. Its compact design, featuring up to four channels with simultaneous secondary output in a single rack unit, significantly reduces operational costs and improves power efficiency.

The ProStream 4000, part of Harmonic’s MediaPrism™ Convergence Suite of software tools for multi-screen video delivery to the TV, PC and mobile devices, supports Microsoft Internet Information Services (IIS) Smooth Streaming and other formats, and is capable of transcoding up to 46 channels simultaneously. The ProStream 4000’s all-IP software-based architecture enables seamless, low-cost integration into existing headends, while flexibly supporting a range of applications.
