Abstract

A conferencing system with improved audio response, interface, and audio source tracking capabilities includes a low-profile base unit capable of capturing and processing audio and video information and of interfacing with other external devices, and a separate network interface device coupled to the low-profile base unit and capable of connecting to a network, producing audible sound, regulating power, and housing removable interface circuitry.

Claims

1. A conferencing system comprising:

a base unit, the base unit comprising;

at least one audio driver; and

an audio capture device; and

an interface device separate from and communicatively coupled to the base unit via an interconnect cable, the interface device comprising;

at least one network interface unit configured to receive information via a network from a remote conferencing device; and

a power regulator configured to supply power from an external source to the conferencing system.

2. The conferencing system of claim 1 wherein the network is selected from the group consisting of:

a local area network, a wide area network, the Internet, and a public switched telephone network.

3. The conferencing system of claim 2 wherein the base unit further comprises a processor configured to perform at least one of:

decoding the information received by the at least one network interface unit from the remote conferencing device; and

encoding audio information captured by the audio capture device for transmission by the at least one network interface unit to the remote conferencing device via the network.

4. The conferencing system of claim 2 wherein the interface device further comprises a processor configured to perform at least one of:

decoding the information received by the at least one network interface unit from the remote conferencing device; and

encoding audio information captured by the audio capture device for transmission by the at least one network interface unit to the remote conferencing device via the network.

5. The conferencing system of claim 2 wherein the interface device further comprises an additional audio driver configured to reproduce at least a portion of audio information received from the remote conferencing device.

6. The conferencing system of claim 5 wherein the additional audio driver is a subwoofer.

7. The conferencing system of claim 2 wherein the interface device further comprises a housing configured to accept one or more removable peripheral interface cards.

8. The conferencing system of claim 7 wherein the one or more removable peripheral interface cards comprise one or more ISDN interface cards.

9. A conferencing system comprising:

a base unit, the base unit comprising;

at least one audio driver;

an audio capture device; and

an image capture device; and

an interface device separate from and communicatively coupled to the base unit via an interconnect cable, the interface device comprising;

at least one network interface unit configured to receive information from a remote conferencing device via a network; and

a power regulator configured to supply power from an external source to the conferencing system.

10. The conferencing system of claim 9 wherein the network is selected from the group consisting of:

a local area network, a wide area network, the Internet, and a public switched telephone network.

11. The conferencing system of claim 10 wherein the base unit further comprises a processor configured to perform at least one of:

decoding the information received by the at least one network interface unit from the remote conferencing device via the network; and

encoding audio information captured by the audio capture device and video information captured by the image capture device for transmission by the at least one network interface unit to the remote conferencing device via the network.

12. The conferencing system of claim 10 wherein the interface device further comprises a processor configured to perform at least one of:

decoding the information received by the at least one network interface unit from the remote conferencing device via the network; and

encoding audio information captured by the audio capture device and video information captured by the image capture device for transmission by the at least one network interface unit to the remote conferencing device via the network.

13. The conferencing system of claim 10 wherein the interface device further comprises an additional audio driver configured to reproduce at least a portion of audio information received from the remote conferencing device.

14. The conferencing system of claim 13 wherein the additional audio driver is a subwoofer.

15. The conferencing system of claim 10 wherein the interface device further comprises a housing configured to accept one or more removable peripheral interface cards.

16. The conferencing system of claim 15 wherein the one or more removable peripheral interface cards comprise one or more ISDN interface cards.

17. The conferencing system of claim 9 further comprising a horizontal microphone array coupled to the base unit.

18. The conferencing system of claim 9 further comprising a vertical microphone array coupled to the base unit.

19. The conferencing system of claim 17 further comprising a vertical microphone array coupled to the base unit.
