Systems and methods for distributed conferencing
Distributed conferencing systems and methods provide local meeting contents to remote participants. In accordance with various example embodiments, a plurality of authorized source units generate media content responsive to and representative of respective content for a meeting. In response to the generated media content, one or more data streams are developed at each authorized source, each stream being a separately-decodable real-time representation of at least a portion of the media content generated at the respective authorized source. The separate data streams are transmitted by each authorized source to a common multicast IP group address for retrieval/access by remote participants.
1. A method comprising:
providing access to a distributed conferencing system that provides local meeting contents to remote participants from a plurality of circuit-based source units, each including logic circuitry configured to process communication data, using a meeting multicast group IP address; and
causing the logic circuitry to perform the steps of:
in response to generating media content responsive to and representative of respective portions of the meeting contents, identifying an IP address associated with a source unit in a corresponding announcement for a meeting to be using the generated media content, automatically configuring one of the source units and developing at least one data stream as a separately decodable real-time representation of at least a portion of the media content;
transmitting the at least one data stream to the meeting multicast group IP address; and
configuring the logic circuitry of at least two source units to transmit to a common meeting multicast group IP address after configuration data is received from another data source, and connecting to the meeting multicast group IP address to communicate via the meeting multicast group IP address.
2. The method of claim 1 , further including, in the logic circuitry at one of the source units,
accessing an announcement that includes a list of authorized data streams;
subscribing to the meeting multicast group IP address to receive a plurality of the data streams;
displaying the media content in response to the list of authorized data streams; and
providing an interface that allows for individual control of multiple ones of the data streams.
3. The method of claim 1 , further including, in the logic circuitry at one of the source units, accessing an announcement that includes a list of authorized data streams.
4. The method of claim 1 , further including, in the logic circuitry at one of the source units, subscribing to the meeting multicast group IP address to receive a plurality of the data streams.
5. The method of claim 1 , further including, in the logic circuitry at one of the source units, displaying the media content in response to the list of authorized data streams.
6. The method of claim 1 , further including, in the logic circuitry at one of the source units,
accessing an announcement that includes a list of authorized data streams; and
providing an interface that allows for individual control of multiple ones of the data streams.
7. The method of claim 1 , further including using the other data source as a system controller.
8. The method of claim 1 , wherein transmitting the at least one data stream includes transmitting identification information in the at least one data stream, the identification information indicating an identity of participants using the source unit.
9. The method of claim 1 , further including receiving the identification information from a wireless card.
10. The method of claim 1 , wherein transmitting the at least one data stream includes transmitting identification information in the at least one data stream, the identification information indicating an identity of participants using the source unit; and
wherein transmitting further includes receiving the identification information from a wireless card.
11. The method of claim 1 ,
further including, in the logic circuitry at one of the source units, performing the step of receiving configuration information from an announcement multicast IP address, and
wherein transmitting includes an act of using the configuration information to identify the meeting multicast group IP address.
12. The method of claim 1 , further including mixing the streams and presenting the media content to participants of the local meeting.
13. The method of claim 1 , wherein the announcement includes an IP address of each respective source unit that is to be used for the meeting and additional information pertinent to the meeting and wherein the announcement is digitally signed as a measure of security.
14. The method of claim 1 , wherein an IP address of each respective source unit that is to be used for the meeting, and additional information pertinent to the meeting, are inserted into the announcement.
15. The method of claim 1 , wherein the announcement includes an IP address of each respective source unit that is to be used for the meeting and additional information pertinent to the meeting and wherein the announcement is digitally signed as a measure of security; and
further including inserting an IP address of each respective source unit that is to be used for the meeting, and additional information pertinent to the meeting, into the announcement.
16. The method of claim 1 , wherein the announcement is digitally signed as a measure of security.
17. The method of claim 1 , further including, in the logic circuitry at one of the source units, determining a type of access for each remote participant using the announcement.
18. The method of claim 1 , further including, in the logic circuitry at one of the source units, determining a selected language for each remote participant using the announcement.
19. The method of claim 1 , further including, in the logic circuitry at one of the source units, tailoring content for the remote participants based on a participant's end device and using the announcement.
20. The method of claim 1 , further including, in the logic circuitry at one of the source units, defining sharing capabilities of the remote participants using the announcement.
