Abstract

A conferencing system supporting active and passive participants is disclosed. The conferencing system includes a client component defining active and passive participants, and a server component having a connection to each active and passive participant defined in the client component. The server component includes a connection manager for managing the connection between each active and passive participant and the server component, a media mixer for receiving conference media and for distributing conference media to active and passive participants, and a virtual producer for selecting conference media to be distributed to passive participants. The conference media provided to the passive participants is dynamically determined based upon activities and selections of a set of active participants.

Claims

1. A conferencing system supporting active participants and passive participants during a conference session in which the active participant has assigned control to select and to configure media for the active participant and the passive participant has no control over media exchange, the conferencing system selects and provides the media to the passive participant, the conferencing system comprising:

a client having a memory storing program instructions configured to identify whether a corresponding participant is one of the active participants or one of the passive participants; and

a server having a connection to each of the active participants and to each of the passive participants, wherein the server communicates with the active participants over both a conference channel and a back channel, the server configured to execute videoconferencing software that defines

a connection manager for managing the connection between the each of the active participants and the each of the passive participants and the server;

a media mixer for receiving conference media and for distributing the conference media to the active participants and the passive participants; and

a virtual producer for selecting the conference media to be distributed to the passive participants, wherein a layout of the conference media provided to the passive participant is dynamically determined based upon input selections sent from a set of the active participants via the back channel that are analyzed by the virtual producer during the conference session;

wherein the virtual producer includes a media ranking module that provides a raw media ranking of all of the conference media based on a list of the all of the conference media of a particular conference, an active participant ranking of the conference media, interest markers associated with the conference media, and indications of triggering events associated with the conference media; and

wherein the virtual producer provides the conference media and the layout of the conference media to the passive participants based on the raw media ranking of the all of the conference media.

2. The conferencing system of claim 1, farther comprising an event handler, the event handler working in cooperation with the connection manager to monitor participant activity and provide information about the participant activity to the media mixer.

3. The conferencing system of claim 1, further comprising a session manager, the session manager being a part of a server component and being configured to define rules of collaboration and rules of the media exchange, wherein the rules of collaboration and the rules of the media exchange control availability of the conference media to the active participants and the passive participants.

4. The conferencing system of claim 1, wherein the virtual producer includes a media analysis module, and a media selection and layout module.

5. The conferencing system of claim 4, wherein the media analysis module receives the raw media ranking of the all of the conference media and analyzes the all of the conference media to provide a media ranking of the media suitable for providing to the passive participants, the media analysis module using system rules and collaboration rules to analyze the raw media ranking of the all of the conference media.

6. The conferencing system of claim 4, wherein the media selection and layout module receives the media ranking of the media suitable for providing to the passive participant and selects media content and a layout for the media content selected to be provided to the passive participant.

7. The conferencing system of claim 1, wherein the connection manager is a peer endpoint for the corresponding participant.

8. A video conferencing system supporting active participants and passive participants during a video conference session in which the active participant has assigned control to select and to configure media for the active participant and the passive participant has no control over media exchange, the conferencing system selects and provides the media to the passive participant, the conferencing system comprising:

a plurality of clients wherein a portion of the plurality of clients are identified as the active participants and a remainder of the plurality of clients are identified as the passive participants, each of the plurality of clients having a memory storing program instructions configured to identify the plurality of clients as one of the active participants or one of the passive participants; and

a server in communication with the each of the plurality of clients during the video conference session, the server communicating with the active participants over both a conference channel and a back channel, the server communicating with the passive participants over the conference channel, the server configured to capture input selections of the active participants to organize a layout of conference media for presentation to the passive participants during the video conference session, the sewer further configured to monitor the input selections sent from the active participants via the back channel to adjust the layout of the conference media during the video conference session;

wherein the sever is configured to execute videoconferencing software that defines

a virtual producer for selecting the conference media to be distributed to the passive participants;

wherein the virtual producer includes a media ranking module that provides a raw media ranking of all of the conference media based on a list of the all of the conference media of a particular conference, an active participant ranking of the conference media, interest markers associated with the conference media, and indications of triggering events associated with the conference media; and

wherein the virtual producer provides the conference media and the layout of the conference media to the passive participants based on the raw media ranking of the all of the conference media.

9. The video conferencing system of claim 8, wherein the server collects the input selections and assigns a weight to rank layouts of the conference media according to the input selections.

10. The video conferencing system of claim 8, wherein the server includes a time delay prior to presenting adjustments of the layout of the conference media to the passive participants.
