Abstract
This paper discusses the design and implementation of a command stream
based on Tcl. A command stream is a series of arbitrary commands that
can be tightly synchronized with other media in a distributed
multimedia presentation. In TclStream, we represent an arbitrary
command as a collection of fragments of Tcl code. The command stream
medium supports the standard manipulation functions of multimedia
environments: reverse, fast-forward, random access, and variable
speed. The ability to specify arbitrary actions, combined with fine
playback control, make TclStream an extremely flexible and powerful
presentation medium.
