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.

Claims2

Dependent claims

A method of recording and playing back, in a multimedia device, an audio and video stream of data comprising the steps of:

accepting at least one tele-conference message comprised of at least one audio and video stream of data transmitted from a remote station via a communication system to said multimedia device;
buffering said accepted at least one audio and video stream of data;
controlling the storage of said at least one audio and video stream of data, so buffered into a random access mass storage device, under the control of a micro-processor such that a plurality of stored audio and video streams are stored;
providing a user controllable signal to said micro-processor to play back at least one of said stored audio and video streams of data stored in said mass storage device;
wherein a play back of said at least one of said stored audio and video streams of data can occur during the accepting, buffering and storing of a combined audio and video stream of data which is different from said played back combined video and audio stream of data.
