Abstract

A videoconferencing system may include a camera, microphones, speakers, and a codec. In some embodiments, the codec functionality may be incorporated in a set-top box (e.g., a cable box, a satellite box, or a gaming box). The codec functionality may also be split between different components of the videoconferencing system. The camera and speakers may be coupled to or placed around a display. The videoconferencing system may send/receive signals through a network coupled to the computer system. The various functions to support the videoconference (e.g., compression and decompression of video signals) may be performed by circuitry in the camera base, codec/set top box, and/or on the computer system. The computer system may be a laptop computer. In some embodiments, ported speakers may be used to maximize sound quality for the provided speaker size.

Claims

1. A set-top box videoconferencing system, comprising:

a set-top box;

a microphone;

a speaker;

a network connection;

a camera, comprising;

a lens portion;

a camera base coupled to the lens portion; and

a codec implemented in the set-top box for processing videoconferencing signals;

wherein the set-top box is coupled to the microphone, speaker, network connection, and camera.

2. The system of claim 1, wherein the set-top box includes a digital video recorder (DVR).

3. The system of claim 2, wherein the DVR is operable to record at least a portion of a videoconference.

4. The system of claim 2, wherein the DVR is operable to record a message left by a participant calling the videoconferencing system.

5. The system of claim 2, wherein the DVR is operable to record a first portion of a conference and replay a second portion of the conference substantially simultaneously.

6. The system of claim 1, wherein the camera is a high definition camera.

7. The system of claim 1, further comprising a microphone array which includes the microphone;

wherein the microphone array is comprised in the camera base.

8. The system of claim 1, further comprising a remote control communicatively coupled to the set-top box.

9. The system of claim 1, wherein the set-top box is coupled to an external network through the network connection.

10. A set-top box videoconferencing system, comprising:

a set-top box;

an array of microphones;

at least two speakers;

a network connection;

a high definition (HD) camera, comprising;

a lens portion;

a camera base coupled to the lens portion; and

a codec implemented in the set-top box for processing videoconferencing signals;

wherein the set-top box is coupled to the array of microphones, at least two speakers, network connection, and high definition camera.

11. The system of claim 10, further comprising an overhead camera for sharing documents.

12. The system of claim 10, wherein the at least two speakers are ported speakers.

13. The system of claim 10, wherein the array of microphones is comprised in the camera base.

14. The system of claim 10, further comprising a remote control communicatively coupled to the set-top box.

15. The system of claim 10, wherein the set-top box is coupled to an external network through the network connection.

16. The system of claim 10, wherein the set-top box includes a digital video recorder (DVR).

17. The system of claim 16, wherein the DVR is operable to record at least a portion of a videoconference.

18. The system of claim 16, wherein the DVR is operable to record a message left by a participant calling the videoconferencing system.

19. The system of claim 16, wherein the DVR is operable to record a first portion of a conference and replay a second portion of the conference substantially simultaneously.

20. The system of claim 10, wherein video processing for the videoconference is distributed between the set-top box and the camera base.
