Abstract
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.
