MENLO PARK, Calif. -- GoBackTV, the innovative supplier of digital video headend and edge solutions, today announced that BKG-Neuruppin in Brandenburg, Germany, has successfully deployed unicast and multicast IPTV services over its cable plant to a combination of city service departments, employees, and subscribers, using the GoBackTV CMTS-bypass solution. Television content is delivered to participants' television sets via off-the-shelf IP set top boxes connected to standard EuroDOCSIS™ 1.1 cable modems.

The GigaQAM® IP, in combination with up to eight GoBackTV GigaQAM 3000 edgeQAMs, changes the economics of delivering downstream IPTV traffic through DOCSIS® cable modems by allowing video payload to bypass the CMTS core processor. Since the GigaQAM IP's core processor can still support and control the same number of modems as an ordinary CMTS, the operator gets to leverage the cost of a CMTS core processor and upstream channels across multiple QAMs-worth of bandwidth--up to 192 QAM channels.

The GigaQAM 3000 edgeQAM encapsulates the IPTV traffic and can propagate timing and control information from the GigaQAM IP on any of its channels. This enables the core-bypass technique to work with existing DOCSIS 1.1 and 2.0 cable modems, as well as the upcoming DOCSIS 3.0 wideband cable modems. The GigaQAM 3000 also supports QAM sharing, in which any individual QAM channel can carry both traditional MPEG-2 content and DOCSIS payload. In addition, the GigaQAM 3000 can function as a broadcast, switched broadcast, or narrowcast edgeQAM, with versatile MPEG-2 remultiplexing, including support for both variable bit rate (VBR) and constant bit rate (CBR) transport streams, in both high definition and standard-definition video rates.

"BKG is proud to offer advanced triple-play services at affordable rates, not just to residential subscribers, but also to our local businesses and city services, including Ruppiner Kliniken hospital, City and District administration, and local hotels," said Mr. Jochen Sill, General Manager of BKG-Neuruppin. "GoBackTV has allowed us to deploy IPTV now over our cable plant with a unified IP infrastructure."
