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.
