HanseNet Telekommunikation, a wholly-owned subsidiary of Telecom Italia, has implemented Harmonic’s ProStream 1000 stream processing capability for forward error correction of the more than 100 digital TV channels delivered as part of HanseNet’s Alice IPTV service in Germany.

By leveraging the ProStream 1000 platform, already deployed at HanseNet with Harmonic’s ProCipher scrambling technology, HanseNet was able to add Pro-MPEG forward error correction (FEC) without investing in new hardware. HanseNet also utilizes Harmonic’s DiviCom Electra MPEG-4 AVC (H.264) encoders and NMX Digital Service Manager to power the Alice video service, said Harmonic.

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.

Jens Pape, director IT and new services of HanseNet, said: We have been working with Harmonic since the launch of our Alice IPTV service in 2006. Harmonic’s IPTV headend services 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.
