Tcl Commands as Media in a Distributed Multimedia Toolkit
نویسنده
چکیده
A command stream is a real-time medium composed of discrete commands. The commands may reside anywhere on the network, but they are executed locally on the machine where other medias are displayed. More generally, they may reside and be executed on any network-connected machines. Since a command stream will be only one media type in an integrated multimedia toolkit, we must be able to operate on it like any other media stream. Therefore a command stream must support the following operations:

The WebWiseTclTk toolkit is an enhancement of the existing feature set of Safe-Tcl and Safe-Tk that does not compromise security. The toolkit re-de nes the functionality of the auto load mechanism in Tcl such that it works for packages located anywhere on the World Wide Web. It also re-introduces several commands not available in Safe-Tk such as toplevel and menu to provide a much richer featur...
متن کاملUsing Tcl to Control a Computer-participative Multimedia Programming Environment
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, eecient interface ...
