In the BT TV Everywhere video infrastructure Elemental’s kit powers a unified headend for subscription linear channels delivered to IPTV set-top boxes as well as multiscreen devices. Elemental Conductor software manages Elemental Live encoder clusters.

The encoded streams pass to Elemental Delta for just-in-time packaging to enable live-to-VOD delivery to connected devices.

Elemental said that this infrastructure enables BT to scale from 90 to 250 channels and to provide subscribers live, on-demand and time-shift services.

For the BT Sport App, Elemental Delta enables viewers to return to match high points, such as goals and penalties through its live-to-VOD output filter.

BT managing director of TV technology and content Greg McCall said: “Through our partnership with Elemental, we are increasing operational efficiency, assuring the highest quality 4K services for our viewers, and providing customers a unified experience across multiple delivery platforms.”
