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 videoconferencing method comprising:

transmitting a video signal of a host to a selected participant, wherein the selected participant does not receive its own video signal and does not receive video signals of non-selected participants, wherein the host is coupled with the selected participant and the non-selected participants;

transmitting a video signal of the selected participant to the host, wherein the host does not receive its own video signal and does not receive the video signals of the non-selected participants; and

transmitting combined video signals of the host and selected participant to the non-selected participants.

2. The method of claim 1 further comprising combining the video signals of the host and selected participant.

3. The method of claim 1 further comprising:

transmitting an audio signal of the host to the selected participant, wherein the selected participant does not receive its own audio signal and does not receive audio signals of non-selected participants;

transmitting an audio signal of the selected participant to the host, wherein the host does not receive its own audio signal and does not receive the audio signals of the non-selected participants; and

transmitting combined audio signals of the host and selected participant to the non-selected participants.

4. The method of claim 1 further comprising selecting the selected participant.

5. The method of claim 1, wherein the selected participant becomes a non-selected participant when the new selected participant is selected.

6. The method of claim 5 further comprising:

transmitting the video signal of the host to the new selected participant, wherein the new selected participant does not receive its own video signal and does not receive video signals of non-selected participants;

transmitting a video signal of the new selected participant to the host, wherein the host does not receive its own video signal and does not receive the video signals of the non-selected participants; and

transmitting combined video signals of the host and new selected participant to the non-selected participants.

7. A videoconferencing method comprising:

transmitting a video signal of a first party to a second party, wherein the second party does not receive its own video signal and does not receive a video signal of a third party, wherein the first party is coupled with the second party and the third party;

transmitting a video signal of the second party to the first party, wherein the first party does not receive its own video signal and does not receive the video signal of the third party; and

transmitting combined video signals of the first and second parties to the third party.

8. The method of claim 7 further comprising combining the video signals of the first and second parties.

9. The method of claim 7 further comprising:

transmitting an audio signal of the first party to the second party, wherein the second party does not receive its own audio signal and does not receive an audio signal of a third party;

transmitting an audio signal of the second party to the first party, wherein the first party does not receive its own audio signal and does not receive the audio signal the third party; and

transmitting combined audio signals of the first and second parties to the third party.

10. The method of claim 7 further comprising selecting the second party.

11. The method of claim 7 further comprising:

transmitting the video signal of the first party to the third party, wherein the third party does not receive its own video signal and does not receive a video signal of the second party;

transmitting the video signal of the third party to the first party, wherein the first party does not receive its own video signal and does not receive the video signal of the second party; and

transmitting combined video signals of the first and third parties to the second party.

12. The method of claim 11, wherein the transmitting acts in claim 11 are performed in response to selecting the third party.

13. The method of claim 7 further comprising transmitting combined video signals of the first and second parties to at least one additional party.

14. The method of claim 7, wherein the first party comprises a host, wherein the second party comprises a selected participant, and wherein the third party comprises a non-selected participant.

15. A method for videoconferencing first, second, and third parties, wherein the first party receives a video signal only of the second party, the second party receives a video signal of only the first party, and the third party received combined video signals of the first and second parties, wherein the first party is coupled with the second party and the third party.

16. The method of claim 15, wherein the first party receives an audio signal only of the second party, the second party receives an audio signal of only the first party, and the third party received combined audio signals of the first and second parties.

17. The method of claim 15, wherein the second party is selected from a queue.

18. The method of claim 15, wherein when the third party is selected, the first party receives a video signal only of the third party, the third party receives the video signal of only the first party, and the second party received combined video signals of the first and third parties.

19. The method of claim 15, wherein the first party comprises a host, wherein the second party comprises a selected participant, and wherein the third party comprises a non-selected participant.
