Abstract

An improved video conferencing system debundles the audio and the video and allows for a user to select which other conference stations will receive audio, which will receive video and which will receive both.

Claims

1. A video conferencing system for implementing a video conference, said system comprising:

a conference bridge;

a plurality of conference stations, each configured to transmit a combined signal comprising a video portion and an audio portion to the conference bridge, at least one of said plurality of conference stations including means to select whether each one of other conference stations participating in the video conference receives, independent of each other among said other conference stations, one of the audio portion only, the video portion only and both audio and video portions of said combined signal.

2. The system of claim 1 wherein said means for selecting includes means for displaying a template on a computer screen and for allowing a user to select, from the template and for each user, whether said each user will receive audio, video, or both.

3. The system of claim 1 wherein said means for selecting includes means for prompting a user to enter telephone digits indicative of said user'"'"'s selection, and for conveying said telephone digits to said conference bridge.

4. The audio conferencing system of claim 1, wherein said at least one station is one of said plurality conference stations that transmits said combined video and audio signal.

5. The audio conferencing system of claim 1, wherein said at least one station is a station other than one of said plurality conference stations that transmits said combined video and audio signal.

6. A video conference station for use in implementing a video conference comprising:

means for transmitting a combined audio and video signal comprising a video portion and an audio portion to a conference bridge; and

means for generating and transmitting to the conference bridge a selection signal indicative of whether each one of a plurality of remote conference stations participating in the conference receives, independent of each other among said remote conference stations, one of the audio portion only, the video portion only and both the audio and video portions of said combined audio and video signal.

7. The video conference station of claim 6 wherein said selection signal comprises as least one DTMF tone.

8. The video conference station of claim 6 further comprising means for permitting a user to complete a template on a computer screen to select whether each of said plurality of remote users receives video or audio or both.

9. A video conferencing system for implementing a video conference, said system comprising:

a conference bridge;

a plurality of conference stations, each configured to transmit a combined signal comprising a video portion and an audio portion to the conference bridge, at least one of said plurality of conference stations including a selector to select whether each one of other conference stations participating in the video conference receives, independent of each other among said other conference stations, one of the audio portion only, the video portion only and both audio and video portions of said combined signal.

10. A video conference station for use in implementing a video conference comprising:

a transmitter to transmit a combined signal comprising a video portion and an audio portion to a conference bridge; and

a generator to generate and transmit to the conference bridge a selection signal indicative of whether to transmit each one of a plurality of remote conference stations participating in the conference, independent of each other among said remote conference stations, one of the audio portion only, the video portion only and both the audio and video portions of said combined signal transmitted by said transmitter.
