A composition display system produces a display presentation in one of a
plurality of formats from an original composition, the formats being
created from the original composition responsive to input variables and a
selected operating mode. The system is comprised of means to receive the
original composition, a memory, a selection subsystem, a controller, a
master display subsystem, and one or more slave display subsystems. The
controller, responsive to the selection subsystem, provides means for
selectively controlling the storing of the original composition in the
memory. The master display subsystem can optionally provide means for
selectively altering the stored original composition to produce a
particular derivative composition. One or more slave display subsystems
provide for displaying a presentation of the original (or optionally the
particular derivative composition) in the selected format responsive to
the master display subsystem. The master display subsystem can provide
control of content and page turns for display on one or a plurality of
the slave display subsystems.
