Abstract
This paper describes how the VuSystem, a programming environment for
the development of computer-participative multimedia applications, is
controlled through Tcl scripts. In the VuSystem, networks of in-band
media-processing modules are created and controlled by interpreted
out-of-band Tcl scripts through object commands and callbacks. Tcl's
extensibility, simple type system, efficient interface to C, and
introspective capabilities are used by the VuSystem to produce a
highly dynamic and capable media processing system.
