Abstract

A system for controlling a video-conference network by the end user at a video conference site which is comprised of a public telecommunications network connected to video-conference controllers at the video conference sites. The video-conference controllers allow the end user to issue single commands which initiate an automated sequence resulting in implementation of the end user command. The commands are designed to provide the end user with real time control of video-conferencing.

(d) a means for allowing the user to access video-conference capability, actuated by the network verification.

11. The video-conference controller of claim 1 which further comprises a means for extending existing video-conferences in progress through the video-conference network.

12. The video-conference controller of claim 11 wherein the means for extending video-conferences further comprises;

(a) a means for receiving a network determination that the video-conference is nearing termination;

(b) a means for receiving a network determination that no other video-conference is scheduled after the video-conference in progress;

(c) a means for prompting the user to request an extension of the video-conference, actuated by the determination that the video-conference is nearing termination and that no other video-conference is scheduled after the video-conference in progress;

(d) a means for allowing the user to input the request for an extension of the video-conference;

(e) a means for initiating an extension of the video-conference with the video-conference network, actuated by the user extension request.

13. The video-conference controller of claim 1 which further comprises a means for accessing off-line help from the video-conference network.

14. The video-conference controller of claim 13 wherein the means for accessing off-line help further comprises:

(a) a means for detecting a pre-determined help condition;

(b) a means for initiating a phone call from the video-conference network to the conference site, initiated by the detection of the help condition.

15. The video-conference controller of claim 1 which further comprises a means for terminating video-conferences.

16. The video-conference controller of claim 1 which further comprises:

(a) a means for comparing user inputs to correct input formats stored in a memory;

(b) a means for re-prompting the user to correct conflicts between the user inputs and the correct input formats;

(c) a means for allowing the user to re-enter inputs.

17. A video-conference system for allowing users to exchange full-motion video at a rate of at least 1,544,000 bits per second to facilitate interactive face to face communication through video-conferences, wherein the system comprises:
