Abstract

A teleconferencing system for voice and data provides interconnections among user sites via a central station. User stations at user sites each alternate operation between a data mode connecting a user computer and modem to a user telephone communication path and a voice mode connecting a telephony circuit to the communication path. The teleconferencing system is adapted for conducting a voice conference over standard telephone lines while allowing simultaneous viewing of data objects such as slides, graphs, or text. A host computer connected to the central station serves as a central repository for storage and retrieval of data objects for use in teleconferences.

Claims

1. A method of conferencing, comprising the, steps of:

retrieving by at least two storage devices, a set of data objects from a host computer;

processing the set of data objects in each storage device, each storage device located at a respective user site and having a storage system for data object storage, wherein the retrieving step and the processing step each occur prior to a conference;

operationally attaching a display system to at least one storage device;

operationally connecting the user site into the conference;

selecting a data object from the set of data objects and transmitting a control signal to indicate the selected data object; and

receiving the control signal and displaying the selected data object on the display system in response to the control signal.

2. The method of claim 1 wherein the set of data objects comprise image data.

3. The method of claim 1 further comprising the step of, at a respective user site, transmitting and receiving a signal to and from other user sites.

4. The method of claim 3 further comprising the steps, at a user site, of:

recording the signals to produce recorded signals;

playing the recorded signals; and

displaying selected data objects on a display system in response to the recorded signals.

11. The method of claim 1, operationally connecting the user site into the conference via a wide area network, wherein the wide area network comprises an Internet network.

12. The method of claim 1, operationally connecting the user site into the conference via a wide area network, wherein the wide area network comprises a satellite network.

13. The method of claim 1, wherein the data objects comprise executable objects.

14. The method of claim 1, wherein the data objects comprise video objects.

15. The method of claim 1, wherein the data objects comprise multimedia objects.

16. The method of claim 1, wherein the data objects comprise image objects.

17. The method of claim 1, wherein the receiving step further comprises;

storing the received control signals;

subsequently retrieving the stored control signals; and

displaying the selected data objects in response to the retrieved control signals.

18. The method of claim 17, wherein the retrieving and displaying steps occur non-simultaneously at each user site.

21. The method of claim 3, wherein the signal is a voice communications signal.

22. The method of claim 1, wherein the set of data objects includes common data objects and private data objects.

5. Apparatus for conferencing, comprising:

a host computer;

at least two storage devices, each said storage device storing a set of data objects retrieved from the host computer for a conference, each said storage device located at a respective user site, and each said storage device having a storage system for data object storage;

a display system, operationally attached to at least one storage device;

a network for interconnecting the user site into the conference;

wherein the user site includes;

(i) a system for selecting a data object from the set of data objects;

(ii) a control signal generator for transmitting a control signal indicating the selected data object to other user sites;

(iii) a receiver for receiving the control signal, the selected data object being displayed on the display system in response to the control signal.

6. The apparatus of claim 5 wherein the user site further comprises a circuit for transmitting and receiving communications signals to and from the other user sites.

7. The apparatus of claim 5 wherein the data objects comprise image data.

19. The apparatus of claim 5, wherein the network comprises an Internet network.

20. The apparatus of claim 5, wherein the network comprises a satellite network.

23. The apparatus of claim 5, wherein the set of data objects includes common data objects and private data objects.

8. A method of conferencing over an Internet network, comprising the steps of:

retrieving by at least two storage devices, a set of data objects from a host computer;

processing the set of data objects in each storage device, each storage device located at a respective user site and having a storage system for data object storage, wherein the processing step occurs prior to a conference over the Internet network;

operationally attaching a display system to at least one storage device;

operationally connecting the user site into the conference;

selecting a data object from the set of data objects and transmitting a conference control signal to other user sites to indicate the selected data object; and

receiving the conference control signal and displaying the selected data object on the display system in response to the conference control signal.

9. The method of claim 8 wherein the data objects comprise image data.

10. The method of claim 8 further comprising the step of at the user site, transmitting and receiving voice communications signals to and from the other user sites.

24. The method of claim 8, wherein the set of data objects includes common data objects and private data objects.

25. A method of conferencing, comprising the steps of:

processing a set of data objects in a storage device, the storage device located at a respective user site and having a storage system for data object storage, wherein the processing step occurs prior to a conference;

operationally attaching a display system to at least one storage device;

operationally connecting the user site into the conference;

selecting a data object from the set of data objects and transmitting a control signal in-band with voice communications signals to indicate the selected data object; and

receiving the control signal and displaying the selected data object on the display system in response to the control signal.

26. The method of claim 25 wherein the data objects comprise image data.

27. The method of claim 25 further comprising the step of, at a respective user site, transmitting and receiving a signal to and from other user sites.

28. The method of claim 27 further comprising the steps, at a user site, of:

recording the signals to produce recorded signals;

playing the recorded signals; and

displaying selected data objects on a display system in response to the recorded signals.

29. Apparatus for conferencing, comprising:

at least one storage device, said storage device storing a set of data objects for a conference and located at a user site, and having a storage system for data object storage;

a display system, operationally attached to at least one storage device;

a network for interconnecting the user site into the conference;

wherein the user site includes;

(i) a system for selecting a data object from the set of data objects;

(ii) a control signal generator for transmitting a control signal indicating the selected data object to other user sites, wherein the control signal is adapted to be transmitted in-band with communications signals;

(iii) a receiver for receiving the control signal, the selected data object being displayed on the display system in response to the control signal.
