Abstract
For some time, the medium-sized television broadcaster has had a requirement for a professional, broadcast television film-chain projector that is both versatile and reliable. Now, to meet this need, there is the Athena 5000 projector, a spin-off of the popular Athena 4000. The new projector offers production capabilities for direct videotape recording from film without need for optical printers, animation stands, videodisc recorders and special-effects devices. Use of solid-state digital CMOS (complementary metal-oxide-semiconductor) circuitry for both local and remote operation over a “prioritized” four-wire system avoids the usual multi-wire electromechanical latching controls. Control functions are electronically latched in the projector electronic processor (a minicomputer) which connects with all controllers, remote or local, and provides individual indication of the operating status of the projector. Reels with up to 5000 ft (1500 m) of 16mm film can be run, and lamp changing is automatic. Among the operational features are slow motion, scene extension, freeze frame, animation, and instant start/stop.
