Envivio's Convergence Series video headend has been selected for Türk Telekom’s IPTV project in Turkey. Türk Telekom will use Envivio 4Caster C4 SD and 4Caster HD30 HD MPEG-4 AVC encoders and the 4Manager NMS, to deliver an extensive line-up of standard and high definition channels for its new IPTV service. Envivio will highlight its complete Convergence Series video headend at IPTV World Forum 2009 in London, March 25-27, Booth 312.

4Caster C4 from Envivio is the world’s first convergence encoder, providing video compression for all three screens of consumer video – TVs, PCs and mobile devices – on a single platform. Its high-availability hardware platform and ultra-flexible embedded software encoding core offer levels of service flexibility and encoding performance upgradeability not possible with traditional hardware-only encoding platforms. Envivio’s 4Caster HD30 delivers high quality, high definition encoded content at less than half the bit rates required by MPEG-2.

Envivio’s Convergence Series architecture allows MPEG-2 content downlinked from satellite to be delivered to the compression system directly over a local IP network. This all-IP, all-digital processing of content eliminates the need for traditional intermediate analog or digital video and audio interfaces between MPEG-2 decoders and MPEG-4 encoders, resulting in reduced cost and improved picture quality. Service reliability is ensured using an M:N automatic redundancy system controlled by the Envivio 4Manager Network Management System.

The Türk Telekom IPTV headend is being installed by Birtel the partner of Envivio in Ankara, Turkey.
