Harmonic is providing its hardware and software for what it said was the world’s largest commercial launch to date of a cable IPTV service.

Harmonic is working with Korean service provider SK Broadband on a unified broadcast IPTV service across SK Broadband’s cable, xDSL and FTTx access networks.

SK Broadband has deployed Harmonic’s Direct-2-Edge (D2E) platform – encompassing Harmonic’s NSG 9000 universal edge QAMs and D2E control software – for the launch of its cable IPTV services.

SK Broadband subscribers will be able to tap into a data service of up to 150 Mbps in their homes by using Harmonic’s NSG 9000 in a modular cable modem termination system (M-CMTS) architecture to a DOCSIS 3.0 cable modem.

By eliminating the outing of video streams through the CMTS, Harmonic said its “by-pass” approach provides an estimated 70 percent infrastructure cost savings.

SK Broadband, previously Hanaro Telecom, serves approximately 6 million subscribers. The new IPTV service was initially offered to subscribers in the Seoul area and now is rapidly expanding to other provinces.

Harmonic also announced today that its SupraLink 1550 nm dense wave division multiplexing (DWDM) transport offering was selected by the province of Salzburg, Austria, for an upgrade to its HFC cable infrastructure.

The new deployment, the first of its kind in the region, will be implemented by Normann Engineering GmbH, a longstanding Harmonic partner and reseller in the region.

Salzburg is in the process of segmenting the HFC network to increase bandwidth to the home for DOCSIS 3.0 data and video services.
