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.
