Germany's HanseNet Implements Harmonic's Forward Error Correction Capabilities to Enhance IPTV Video Quality


Utilizes Harmonic's Multi-Function ProStream™ 1000 Stream Processing Platform to Provide Scrambling and FEC for Higher Quality Video Service

Last Updated: April 22, 2009 4:06 pm GMT
(NAB 2009 Booth SU7209--April 22, 2009) Harmonic Inc. (NASDAQ: HLIT) today announced that HanseNet Telekommunikation GmbH, a wholly owned subsidiary of Telecom Italia, has implemented Harmonic's ProStream™ 1000 stream processing capability for forward error correction (FEC) of the more than 100 digital TV channels delivered as part of HanseNet's Alice IPTV service in Germany.

By leveraging the versatile ProStream 1000 platform, already deployed at HanseNet with Harmonic's ProCipher™ scrambling technology, HanseNet was able to efficiently add Pro-MPEG FEC without investing in new hardware, lowering both capital and operating expenditures. HanseNet also utilizes Harmonic's market-leading DiviCom® Electra® MPEG-4 AVC (H.264) encoders and NMX Digital Service Manager™ to power the Alice video service.

In an IP-based video service in which data packets can be lost or corrupted during transmission, FEC enables the restoration of the video to its original state -- a critical capability for provisioning superior-quality high definition (HD) and standard definition (SD) TV. The Institut für Rundfunktechnik, a leading research institute for public-broadcasting organizations in Germany, Austria and Switzerland, has worked with Harmonic and HanseNet to verify compatibility with the DVB IPTV standard.

"We have been working with Harmonic since the launch of our Alice IPTV service in 2006," said Jens Pape, director of IT and new services for HanseNet. "Harmonic's IPTV headend solutions provide excellent encoding at low bit-rates and a simple solution for scrambling and service management. Now, with the addition of the FEC capabilities, we are able to improve video quality even further and provide our viewers with a better user experience."

"We have been testing the IPTV services offered by HanseNet,” said Wolfgang Graf, general manager of television for Institut für Rundfunktechnik. "The services comply fully with the relevant DVB standards."

The dense and highly flexible ProStream platform is the world's first multifunctional stream processing system, capable of being configured to support FEC, multiplexing, DiviTrackIP™ statistical multiplexing, ProCipher scrambling and descrambling, Mentor™ re-encoding and single frequency network (SFN) transmission over IP. The compact and scalable 1-RU ProStream can transmit and receive up to 128 single program transport streams (SPTS) or eight multiple program transport streams (MPTS) with forward error correction.

"Harmonic recognized the trend toward IP-based video delivery several years ago and has remained focused on providing video service providers with the most innovative and highest quality solutions to deliver a best-in-class IPTV service," said Yaniv Ben-Shushan, product marketing manager for Harmonic Inc. "HanseNet's successful Alice service and the implementation of the FEC capabilities on the ProStream 1000 platform is an example of how we can work with our customers to simply and cost-effectively enhance the video service."
