Abstract

An improved videoconferencing system and method are provided for connecting a host to a plurality of participants. Unlike other videoconferencing methods and systems, the videoconferencing system and method of these preferred embodiments allow each of the parties of a videoconference to benefit from the interaction between the host and the selected participant without limiting the number of participants that can join the videoconference. The host and participants can interact with the videoconferencing system by issuing voice commands or DTMF signals to a voice response unit or by using a computer to access the videoconferencing system directly or indirectly though a network such as the World Wide Web.

Claims

1. A method for use in a system comprising a network coupling a first party with a plurality of parties, one of the plurality of parties comprising a second party, the method comprising:

(a) receiving a request from the second party via the World Wide Web;

(b) transmitting video of the first party to the second party, wherein the second party does not receive its own video and does not receive video of the other parties of the plurality of parties;

(c) transmitting video of the second party to the first party, wherein the first party does not receive its own video and does not receive video of the other parties of the plurality of parties; and

(d) transmitting combined video of the first and second parties to the other parties of the plurality of parties.

2. The method of claim 1 further comprising:

transmitting audio of the first party to the second party, wherein the second party does not receive its own audio and does not receive audio of the other parties of the plurality of parties;

transmitting audio of the second party to the first party, wherein the first party does not receive its own audio and does not receive audio of the other parties of the plurality of parties; and

transmitting combined audio of the first and second parties to the other parties of the plurality of parties.

3. The method of claim 1, wherein one of the plurality of parties comprises a third party, and wherein the method further comprises:

receiving a request from the third party via the World Wide Web;

transmitting video of the first party to the third party, wherein the third party does not receive its own video and does not receive video of the other parties of the plurality of parties;

transmitting video of the third party to the first party, wherein the first party does not receive its own video and does not receive video of the other parties of the plurality of parties; and

transmitting combined video of the first and third parties to the other parties of the plurality of parties.

4. The method of claim 1 further comprising, in response to receiving the request, adding the second party to a queue, and wherein (b)-(d) are performed in response to the first party selecting the second party from the queue.

5. The method of claim 1, wherein the first party and the plurality of parties comprise parties to a videoconference.

6. The method of claim 1, wherein (b)-(d) are performed using at least one video switch, a videoconferencing unit, and a tandem video switch.

7. A system comprising:

a network coupling a first party with a plurality of parties, one of the plurality of parties comprising a second party; and

at least one network component in the network, the at least one network component being operative to;

receive a request from the second party via the World Wide Web;

transmit video of the first party to the second party, wherein the second party does not receive its own video and does not receive video of the other parties of the plurality of parties;

transmit video of the second party to the first party, wherein the first party does not receive its own video and does not receive video of the other parties of the plurality of parties; and

transmit combined video of the first and second parties to the other parties of the plurality of parties.

8. The system of claim 7, wherein the at least one network component is further operative to:

transmit audio of the first party to the second party, wherein the second party does not receive its own audio and does not receive audio of the other parties of the plurality of parties;

transmit audio of the second party to the first party, wherein the first party does not receive its own audio and does not receive audio of the other parties of the plurality of parties; and

transmit combined audio of the first and second parties to the other parties of the plurality of parties.

9. The system of claim 7, wherein one of the plurality of parties comprises a third party, and wherein the at least one network component is further operative to:

receive a request from the third party via the World Wide Web;

transmit video of the first party to the third party, wherein the third party does not receive its own video and does not receive video of the other parties of the plurality of parties;

transmit video of the third party to the first party, wherein the first party does not receive its own video and does not receive video of the other parties of the plurality of parties; and

transmit combined video of the first and third parties to the other parties of the plurality of parties.

10. The system of claim 7, wherein the at least one network component is further operative to, in response to receiving the request, adding the second party to a queue.

11. The system of claim 7, wherein the first party and the plurality of parties comprise parties to a videoconference.

12. The system of claim 7, wherein the at least one network component comprises at least one video switch, a videoconferencing unit, and a tandem video switch.

13. A system comprising:

a network coupling a first party with a plurality of parties, one of the plurality of parties comprising a second party;

means for receiving a request from the second party via the World Wide Web;

means for transmitting video of the first party to the second party, wherein the second party does not receive its own video and does not receive video of the other parties of the plurality of parties;

means for transmitting video of the second party to the first party, wherein the first party does not receive its own video and does not receive video of the other parties of the plurality of parties; and

means for transmitting combined video of the first and second parties to the other parties of the plurality of parties.

14. The system of claim 13 further comprising:

means for transmitting audio of the first party to the second party, wherein the second party does not receive its own audio and does not receive audio of the other parties of the plurality of parties;

means for transmitting audio of the second party to the first party, wherein the first party does not receive its own audio and does not receive audio of the other parties of the plurality of parties; and

means for transmitting combined audio of the first and second parties to the other parties of the plurality of parties.

15. The system of claim 13, wherein one of the plurality of parties comprises a third party, and wherein the system further comprises:
