The BBC has ordered 26 of Eyeheight’s new BT-1 burnt-in timecode generators for installation in the Television News area at White City, London. The order came via systems engineering company ATG Spectrum (UK) Ltd. The generators read vertical-interval timecode (VITC) from an SDI signal and overlay hours/minutes/seconds/field over the viewed image in any of four different display modes with user-selectable screenposition/size and user-selectable character colour and background colour. An integral safe-area generator provides masking cursors for 4:3, 14:9 and 16:9 formats.
The BT-1 generators will be used with eight post-production edit suites linked to the BBC’s Broadcast Network Control System (BNCS). Two BT-1 channels can be accommodated on a single Eurocard, allowing up to 12 channels in an Eyeheight Digital geNETics 1 RU enclosure. A single RS-422 link will control all 26 generators via an I-Bus network. I-Bus has the capacity to communicate with 192 devices via RS-422 at up to 100 kbit/s data rate and is being used by an increasing number of broadcast equipment manufacturers as a highly cost-effective control architecture.
