Integration of audio conference bridge with video multipoint control unit
First Claim
1. A method comprising:
- detecting, by an audio conferencing bridge, an attempt by an endpoint to establish a plurality of multimedia sessions;
negotiating a dummy session between the audio bridge and the video MCU, the dummy session for indicating to the video MCU when the endpoint is an active speaker in a conference session; and
sending a generic audio clip to the video MCU in response to the endpoint becoming the active speaker.

Abstract
In one embodiment, a system includes a video multipoint control unit (MCU) and an audio conferencing bridge, the audio conferencing bridge being operable to receive audio streams from audio-only and video endpoints, and to negotiate video sessions between each of the video endpoints and the video MCU. In response to detecting when one of the video endpoints is an active speaker, the audio conferencing bridge transmitting a dummy audio stream over a dummy audio channel from the audio conferencing bridge to the video MCU. The dummy audio stream causes the video MCU to switch an image in a video output stream. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure.

1. A method comprising:
-
detecting, by an audio conferencing bridge, an attempt by an endpoint to establish a plurality of multimedia sessions; negotiating a dummy session between the audio bridge and the video MCU, the dummy session for indicating to the video MCU when the endpoint is an active speaker in a conference session; and sending a generic audio clip to the video MCU in response to the endpoint becoming the active speaker. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8)

9. A method comprising:
-
receiving audio media streams from a plurality of endpoints participating in a conference session, the endpoints including audio-only endpoints and video endpoints; receiving control signals from the plurality of endpoints; establishing a video media channel between each of the video endpoints and a video multipoint control unit (MCU); detecting that a first video endpoint is an active speaker in the conference session; sending a pre-recorded audio clip to the video MCU over an audio channel associated with the first video endpoint, the video MCU sending an image of a user of the first video endpoint to one or more of the video endpoints in response to the pre-recorded audio clip. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A computer readable memory encoded with a non-transitory computer program product, when executed the non-transitory computer program product being operable to:
-
detect when a first video endpoint becomes an active speaker in a conference session among one or more audio-only endpoints and a plurality of video endpoints which includes the first video endpoint; send a dummy audio stream to a video bridge via an audio channel that corresponds to the first video endpoint, the dummy audio stream including generic audio that causes the video bridge to include an image received from the first video endpoint in an output video stream; detect when the first video endpoint is no longer the active speaker; and halt the sending of the dummy audio stream. - View Dependent Claims (18, 19, 20, 21)

22. A method comprising:
-
detecting, by an audio conferencing bridge, an attempt by an audio/video (A/V) endpoint to establish a video session; negotiating, by the audio conferencing bridge, a session between the A/V endpoint and a video multipoint control unit (MCU); negotiating a dummy session between the audio bridge and the video MCU, the dummy session for indicating to the video MCU when the A/V endpoint is an active speaker in a conference session; and sending a generic audio clip to the video MCU in response to the A/V endpoint becoming the active speaker. - View Dependent Claims (23, 24, 25)
