EnvivioIP video convergence solutions : Envivio Inc., the leading technology provider of IP video convergence solutions from mobile to HD, introduced its Convergence Generation headend supporting an all IP infrastructure for IPTV and mobile TV service providers. As part of the new headend, the company also debuted at the IPTV World Forum its fourth generation, multichannel IP video encoder, the revolutionary 4Caster C4 whose unique and flexible architecture will ultimately bring together the Envivio MPEG-4 video compression expertise and industry leading video quality to offer a multi-channel, multi-service encoder capable of addressing Mobile TV, Desktop TV and IPTV at extremely low bandwidths.

The Envivio Convergence Generation headend features the new Envivio IP Gateway, the new 4Caster C4 IPTV encoders and the award-winning 4Caster M2 Mobile TV encoders both with IP ingest, as well as the 4Manager network management and redundancy system. Together, the all-IP architecture provides a multi-service platform capable of addressing the key devices targeted by service providers who control both fixed and wireless networks. Once again demonstrating its unremitting commitment to empower a converged IP world, the Convergence Generation headend provides a full end-to-end IP architecture from video reception to subscribers’ TVs or mobile devices. The headend offers flexible routing, simplified management and redundancy, requires less space and is easier to manage and deploy than today’s traditional IPTV and mobile TV headends.

Envivio headend supporting
“The Convergence Generation headend, with its all-IP infrastructure, represents the future for service providers who must compete in a fixed to mobile environment,” said Julien Signès, President and CEO of Envivio Inc. “Its architecture and infrastructure support today’s and tomorrow’s IP video digital business models.” The Convergence Generation headend is ideal for telco environments. Instead of perpetuating the use of costly and complex broadcast systems in an IPTV network, the all-IP solution was designed specifically for IPTV. For example, the Envivio DVB-to-IP gateway feeds IP video networks with video services coming from satellite, cable, terrestrial and DVB-ASI networks. Each gateway receives MPEG-2 streams and can replace up to 24 IRDs. The Convergence Generation headend architecture is a fundamental milestone for the video compression industry as it meets the challenges posed by network convergence towards IP and the demand by merged fixed line and mobile carriers for multiservice platforms.

Envivio IP video encoding system
A revolutionary encoding system for IPTV deployments, the fourth generation 4Caster C4 delivers the industry’s highest video quality and is built on a flexible standards-based architecture. The quad-channel C4 supports MPEG-2 Transport Stream over IP input, MPEG-4 AVC/H.264 video and AAC audio encoding and configurable output resolutions. As part of the Convergence Generation headend, the C4 receives, decodes, encodes, and transmits programming in an IP environment while increasing encoder density and reducing rack usage. Based on the latest quad-core Intel processors, the flexible architecture adopted by Envivio for the 4Caster C4 allows the service provider to receive firmware upgrades from Envivio to quickly react to market demands for new features. New features and functions can be added easily to each encoder without the need to replace units deployed in the field or to schedule down-time.

“Unlike DSP or ASIC based products, the Intel architecture of the 4Caster C4 is flexible and allows for a greater capacity to enhance the C4 with new codecs and formats,” continued Signès. “Video encoding is a constantly evolving science and our technology approach allows operators to stay at the leading edge of that evolution.”
