Abstract

A videoconferencing system includes a camera, a microphone, and an interface module. The module is coupled a modem connected to a television network and is coupled to a television set and a set-top box. The module decodes encoded audio video signals received from the modem that are part of a videoconferencing session. The module also encodes audio and video signals received from the camera and the microphone and sends the encoded audio video signals to the modem to be part of the videoconferencing session. The module can selectively send decoded audio signals to the television set or can selectively send video received from the set-top box to the television display. In addition, the module can send compressed audio and video signals received from the microphone and camera to the set-top box for processing and delivery to the television display.

Claims

a camera transmitting video signals;

a microphone transmitting audio signals; and

a controller coupled to the camera, the microphone, a television set, a set-top box, and a modem, the modem connected to a television network, the set-top box connected to the television network, the controller configured to;

receive video signals from the modem and from the set-top box;

decode the video signals received from the modem,

selectively send uncompressed video signals to the television set with a video selector, the uncompressed video signals including the video signals received at the modem in a first selected mode, at the set-top box in a second selected mode, and at both the modem and the set-top box in a third selected mode,

send compressed video signals to the modem, the compressed video signals including video signals received from the camera,

decode encoded audio signals received from the modem,

selectively send uncompressed audio signals to the television set,

encode audio signals received from the microphone, and

send encoded audio signals to the modem.

2. The system of claim 1, wherein the television network comprises a cable television network.

3. The system of claim 1, wherein the video signals received from the camera comprise compressed or uncompressed video signals from the camera.

4. The system of claim 1, wherein the controller comprises a control module controlling operation of the video selector to selectively send the uncompressed video signals including the video signals received at the modem, at the set-top box, and at both the modem and the set-top box to the television set.

5. The system of claim 1, wherein to selectively send uncompressed audio signals to the television set, the controller is configured to:

receive audio signals from the modem and from the set-top box; and

selectively send the uncompressed audio signals including the audio signal received at the modem in the first selected mode, at the set-top box in the second selected mode, and at both the modem and the set-top box in the third selected mode to the television set.

6. The system of claim 5, wherein the system comprises an audio selector, and wherein the controller comprises a control module controlling operation of the audio selector to selectively send the uncompressed audio signals including the audio signals received at the modem, at the set-top box, and at both the modem and the set-top box to the television set.

7. The system of claim 1, wherein the controller comprise a video module having a decoder to decode encoded video signals received from the modem and having an encoder to encode video signals received from the camera.

8. The system of claim 7, wherein the controller comprise an audio module having a decoder to decode encoded audio signals received from the modem and having an encoder to encode audio signals received from the microphone.

9. The system of claim 1, wherein the controller comprises a network interface module coupled to the modem, the network interface module establishing a videoconference session using H.323 protocol, Session Initiation Protocol, Internet Protocol, or an intermediate server.

10. The system of claim 9, wherein the network interface module establishes a videoconference session with another videoconferencing device using the intermediate server.

11. The system of claim 1, wherein the camera comprises circuitry for compressing video, whereby the circuitry transmits compressed video signals to the controller.

12. The system of claim 11, wherein the controller sends compressed video signals to the set-top box via a channel available on the set-top box for processing and delivery to the television set.

13. The system of claim 1, wherein the microphone comprises circuitry for compressing audio, whereby the circuitry transmits compressed audio signals to the controller.

14. A videoconferencing system, comprising:
