Abstract
A teleconferencing system with capability to store incoming multiple medium messages for later retrieval and playback is disclosed. The system includes a communications multiplexer which, in normal mode, receives the incoming message and routes the message to various output functions, including video, audio, and computer display. In store mode, the communications multiplexer receives the incoming message and communicates it to disk storage, for example by way of direct memory access. During playback, the communications multiplexer receives data from the disk storage, and controls its communication to the various output functions, in the same manner as during receipt of a normal incoming message during an interactive teleconference. As a result, multiple medium messages may be stored for later retrieval, with the playback appearing in the same manner as a conventional teleconference message.
