Envivio Helps RingNett Expand IPTV Service Reach

By Anuradha Shukla

Envivio is providing a Convergence (News - Alert) Generation video headend to Norwegian ISP RingNett AS to enable the rollout of its Digital-TV IPTV service across its ADSL2+ infrastructure.

The Digital-TV service from RingNett is available to beta customers subscribing to its optical fiber-based GPON high-speed Internet delivery service. RingNett will also support an Envivio MPEG-4 AVC (H.264) encoding platform, to offer the same IPTV (News - Alert) content both over xDSL (ADSL2+ and VDSL2) and FTTx (GPON and Active Ethernet) without compromising video quality.
Envivio (News - Alert) explained that the Convergence Generation solution picked by RingNett is based around the 4Caster C4 multichannel IP video compression system. The C4 boasts an IP input that allows digital TV content downlinked from satellite to be input as MPEG-2 transport streams over IP.
Thanks to the solution’s unique IP architecture, C4 encoding platform can be fed directly from the existing RingNett downlink system, which delivers MPEG-2 services over GPON and Active Ethernet, without major re-engineering of the video headend.
Eirik Lund, CEO of RingNett AS said in a statement that their company realized that MPEG-2 stream processing they were using for their fiber delivery could not offer the quality of service their customers have come to expect from them at the bandwidths they needed to make ADSL2+ delivery feasible.
Lund indicated that MPEG-4 AVC transcoding was the obvious choice, and after reviewing similar solutions from several other vendors they chose Envivio, based on their track record, very impressive support team and diligent account management.
RingNett intends to offer high availability VOD services and 60 channels of standard definition (SD) IPTV by utilizing MPEG-2 streams taken directly from satellite and delivered over high bandwidth fiber connections. According to Envivio, transcoding these services to MPEG-4 AVC (H.264) more than halves the bandwidth required to achieve the same video quality. It also converts the variable bit rate (VBR) satellite feeds to the constant bit rate (CBR) streams required for reliable xDSL delivery.
Lund further explained that they already have a satellite downlink system that feeds MPEG-2 services over IP for delivering IPTV content to their fiber connected subscribers. The C4 just slots in to their existing headend and gives them nearly instant access to the much larger number of subscribers we have on their ADSL2+ network.
The Envivio solution puts RingNett AS in a position to leverage both their existing ADSL2+ clients, and clients on their emerging FTTx networks, using the same open and scalable IPTV service platform.
Julien Signès, president and CEO of Envivio said that they designed the IP architecture of the C4 encoder specifically to simplify this type of fiber to DSL service extension.
Signès is confident that moving to Envivio’s very efficient MPEG-4 AVC encoding will allow RingNett to offer their IPTV service to many more customers.
RingNett AS is a Norwegian ISP building and operating a multi access playout platform for xDSL and FTTx network in Norway offering broadband Internet access, VoIP and IPTV with VOD to end users.
