Abstract

A conferencing system and method are disclosed. An exemplary system includes a conference device and one or more user devices. The conference device is configured to receive audio information from one or more user devices. The audio information received by the conference device can be mixed with audio information received by conference device microphones.

Claims (34)

1. A conferencing system comprising:

a conference device comprising a conference device processor, a plurality of conference device microphones, and a plurality of speakers; and

a user device comprising a user device processor, a user client, and a user device microphone, wherein the user device processor encodes audio information for transmission to the conference device, and

wherein the user device is directly coupled to the conference device using a virtual connection,

wherein the conference device processor is configured to decode audio information received from the user device, mix decoded audio information with audio information received from the plurality of conference device microphones, and cancel an echo from audio information received from the user device,

wherein mixed decoded audio information and audio information received from the plurality of conference device microphones is transmitted to the plurality of speakers, and

wherein the user device directly streams encoded audio information to the conference device, without an intervening server.

2. The conferencing system of claim 1 , wherein the plurality of speakers includes an array of speakers.

3. The conferencing system of claim 1 , wherein the virtual connection is an internet protocol connection.

4. The conferencing system of claim 1 , wherein the user device encodes the audio information into VoIP packets.

5. The conferencing system of claim 4 , wherein the user device encodes the audio information into RTP packets.

6. The conferencing system of claim 1 , wherein the user device processor comprises an adjustable gain device.

7. The conferencing system of claim 1 , further comprising a server coupled to the conference device.

8. The conferencing system of claim 1 , wherein the conference device mixes audio information from a plurality of user devices.

9. The conferencing system of claim 1 , wherein the user client initiates an authentication process between the conference device and the user device.

10. A conferencing method comprising the steps of:

establishing a direct connection, without an intervening server, between a user device and a conference device having a plurality of conference device microphones, a processor, and a plurality of speakers;

streaming encoded audio information using a virtual connection between the user device and the conference device;

decoding audio information received from the user device;

mixing decoded audio information with audio information received from the plurality of conference device microphones;

cancelling an echo from audio information received from the user device; and

using the processor, transmitting decoded audio information and audio information received from the plurality of conference device microphones to the plurality of speakers.

11. The conferencing method of claim 10 , wherein the step of establishing a connection comprises the user device initiating an authentication process with the conference device.

12. The conferencing method of claim 11 , wherein the authentication process comprises NFC authentication.

13. The conferencing method of claim 10 , wherein the step of establishing a connection comprises verifying authentication of the user device.

14. The conferencing method of claim 10 , wherein the step of establishing a connection comprises opening up a receive port on the conference device.

15. The conferencing method of claim 10 , wherein the step of establishing a connection comprises transmitting a network address associated with the conference device to the user device.

16. The conferencing method of claim 10 , wherein the step of establishing a connection comprises using a user client to connect a user device microphone to a transmit port of the user device.

17. The conferencing method of claim 10 , wherein the step of establishing a connection comprises connecting the transmit port of the user device to a receive port on the conference device.

18. A conferencing system comprising:

a conference device comprising a conference bridge, a processor, a plurality of conference device microphones, and a plurality of speakers; and

a user device comprising a user device processor, a user client, and a user device microphone,

wherein the user device processor encodes audio information for direct transmission to the conference device, without use of an intervening server, and

wherein the conference device receives and decodes the audio information, mixes decoded audio information with audio information received from the plurality of conference device microphones, cancels an echo from audio information received from the user device, and transmits mixed decoded audio information and audio information received from the plurality of conference device microphones to the plurality of speakers.
