DNF Controls and Sony Corp. have created an integrated control system so that DNF's
"4000CL" production switcher interface can control individual video segments
stored on Sony "MAV-555A" and "MAV-777" multiaccess video-disk recorders.
DNF said users will have one-button control of transitions, openings and
other preprogrammed elements. This is the third time the two companies have
worked together on a control system for MAV recorders.
