Envivio Inc, which provides IP video convergence encoding solutions from mobile to HD, has sold its Convergence Series video head-end to Türk Telekom's local IPTV project. Türk Telekom is one of the world's largest Tier 1 telecoms operators serving more than 30 million customers and will use Envivio's 4Caster C4 SD, 4Caster HD30 HD MPEG-4 AVC encoders and 4Manager NMS to deliver an extensive line-up of standard and high-definition channels for its new IPTV service.

4Caster C4 is claimed by Envivio to be 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 analogue 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.
