The Terminal Manager is a TAPI 3.x component that allows an application developer to create, add, and remove pluggable terminals. This component also includes three predefined pluggable terminals: Media Streaming Terminal, File Playback Terminal, and File Record Terminal.
The Media Streaming Terminal allows an application to retrieve and send media data to a DirectShow media stream.
The File Playback Terminal allows an application to playback a media file.
The File Record Terminal allows an application to save media stream into a file.
