Audiovisual reproduction system triggered by payment from a user,
developed around a microprocessor device, said system comprising memory
containing, in compressed digital form, audio and visual information to
be used, a display and digital audio reproduction unit enabling formation
of a multimedia environment, wherein the display comprises a video
monitor and an interactive interface with the user by an interface
program which reacts to external events and translates the external
events for a multitasking operating system as events which trigger, via a
graphical module of a library of integrated tools and services, a display
of windows or frames providing a modification of physical operating
parameters of the audiovisual reproduction system, said external events
comprising at least a down event interpreting coincidence of a placement
of pointing device with the position of at least a representation
displayed by the graphic module, and an event which triggers modification
of the physical operating parameters by storing these parameters in said
memory.
