Abstract

A method of conducting an audio-visual conference among a number of conference rooms comprising storing predetermined conference configuration data in a computer system for a plurality of room types and a plurality of combinations of configuration factors, receiving conference variable data, generating a room list of included conference rooms, generating interconnection data for each included conference room according selected by said a computer system performing a recursive process until a feasible set of configuration data is found which permits interconnection to every other included conference room, and if no applicable set of configuration data is feasible, the distribution process returns to a next higher room in said room list.

Claims

1. A method of conducting an audio-visual conference among a number of conference rooms comprising:

storing predetermined conference configuration data in more or more computer data tables in a computer system;

said conference configuration data including information for a plurality of room types, where each room type has a unique combination of active participant displays and active participant cameras;

for at least one room type, said conference configuration data has a plurality of unique, feasible combinations of configuration factors, where said configuration factors include, a number of rooms in the conference, and a maximum number of streams to be distributed to another room in the conference,

for at least one of said plurality of unique, feasible combinations of configuration factors for said one room type, said conference configuration data includes a plurality of unique, feasible permutations of the number of streams that can be distributed to and received from every other room in the conference;

for each unique, feasible permutation of the number of streams that can be distributed to and received from every other room in the call, said conference configuration data includes stream IDs to be distributed to and received from every other room in the conference, where a stream ID designates a physical position in which an associated participant camera and participant display pair is located in a composite participant display;

for each unique combination of configuration factors having more than one set of (i) the number of streams that can be distributed to and received from every other room in the conference and (ii) stream IDs to be distributed to and received from every other room in the call, said conference configuration data includes a relative preference of each set;

receiving at said computer system conference variable data including identities of a plurality of included conference rooms to be interconnected in a conference, and including a desired maximum number of streams to be distributed to another room in the conference entered by a user or selected by said computer system;

based on said conference variable data, said computer system generating a room list comprising every included conference room and having a highest room at a top of said room list and having a lowest room at a bottom of said room list, and said computer system determining a number of rooms in the conference and a room type for every included conference room;

based on said conference variable data and said room list, said computer system generating interconnection data for each included conference room, said interconnection data comprising instructions to interconnect teleconference equipment in each included conference room to teleconference equipment in every other included conference room;

for each included conference room, said interconnection data being generated according to configuration information in a most preferable, feasible set of configuration data among applicable conference configuration data;

for each included conference room, said most preferable, feasible set of configuration data being selected by said computer system performing a recursive stream distribution process in which said computer system steps through said room list from said highest room to said lowest room and, for each room, steps through any applicable sets of said configuration data in successive order from most preferable to least preferable, according to said relative preference, until a feasible set of configuration data is found which permits interconnection to every other included conference room according to the information in the feasible set of configuration data, and if no applicable set of configuration data is feasible for a current room being processed, then the distribution process returns to a next higher room in said room list and selects an applicable set of configuration data having a lesser relative preference than a previous set of configuration data selected for said next higher room, and then the distribution process again attempts to select a most preferable, applicable set of configuration data for said current room; and

transmitting said interconnection data to teleconference equipment in each included conference room to initiate said conference.

2. A method of conducting an audio-visual conference among a number of conference rooms, as in claim 1, wherein for at least room type, said configuration factors includes a plurality of unique room modes.

3. A method of conducting an audio-visual conference among a number of conference rooms, as in claim 1, wherein:

said conference configuration data includes physical position indicators for each connected participant camera to be connected to another included conference room, and includes indicators as to which other included conference room each connected participant camera is connected, based on a relative position in said room list; and

said configuration data indicates physical position indicators for each connected participant display to be connected to another included conference room, and includes indicators as to which other included conference room each connected participant display is connected, based on said relative position in said room list.

4. A method of conducting an audio-visual conference among a number of conference rooms, as in claim 1, wherein:

after receipt of said identities of said included conference rooms, said computer system determines an optimal number of streams which may be commonly exchanged between all included conference rooms; and

said computer system sets said desired maximum number of streams equal to said optimal number of streams.

5. A method of conducting an audio-visual conference among a number of conference rooms, as in claim 1, wherein:

after receipt of said identities of said included conference rooms, said computer system determines an absolute maximum number of streams which may be exchanged between two of said included conference rooms; and

during receipt of said conference variable data, said computer system presents said user with means to select said desired maximum number of streams from one stream to said absolute maximum number of streams.

6. A method of conducting an audio-visual conference among a number of conference rooms, as in claim 5, wherein:

said computer system determines an optimal number of streams which may be commonly exchanged between all included conference rooms; and

in the absence of a selection of a desired maximum number of streams by said user, said computer system sets said desired maximum number of streams equal to said optimal number of streams.

7. A method of conducting an audio-visual conference among a number of conference rooms, as in claim 1, further comprising:

said computer system configuring teleconference equipment in a first room of said included conference rooms to send first and second video streams to a second room of said included conference rooms, by configuring first and second participant cameras in said first room to capture first and second groups of participants, respectively, where said first and second groups of participants are seated at first and second sets of seating locations, respectively;

said computer system configuring teleconference equipment in said second room to display said first and second video streams on first and second participant displays, respectively, in said second room;

first and second sets of participant microphones are associated with said first and second sets of seating locations, respectively, in said first room;

said computer system configuring teleconference equipment in said first and second rooms to reproduce a first audio signal on a first participant speaker associated with said first participant display in said second room, where said first audio signal consists essentially of audio signals generated by said first set of participant microphones; and

said computer system configuring teleconference equipment in said first and second rooms to reproduce a second audio signal on a second participant speaker associated with said second participant display in said second room, where said second audio signal consists essentially of audio signals generated by said second set of participant microphones.
