Abstract

A terminal device which can set a connection status of a communication tool line between terminal devices in various ways and an electronic conference system having such a terminal device are provided. The terminal device for communicating information between remote terminal devices comprises a connection status operation/control unit for setting a connection status of a line to be used by the communication tool, a connection modification unit for changing the line connection in accordance with the content set by the connection status operation/control unit, a connection status modification convey unit for outputting the content set by the connection status operation/control unit to other terminal device, and a connection status modification inform unit for receiving the content of the modification of the line connection from the other terminal.

Claims

1. A communication conference apparatus comprising:

setting means for setting a direction of communication between said apparatus and each of the other communication conference apparatuses participating in a communication conference, said setting means setting said direction at any time during the communication conference; and

connecting means for connecting communication lines in accordance with the direction of communication set by said setting means.

2. A communication conference apparatus according to claim 1, wherein the direction of communication is one of unidirectional transmission only, unidirectional reception only and bidirectional communication.

3. A communication conference apparatus according to claim 1, further comprising display means for displaying said other communication conference apparatuses participating in the communication conference.

4. A communication conference apparatus according to claim 3, wherein the setting by said setting means is displayed on said display means.

5. Apparatus according to claim 1, wherein said apparatus communicates at least voice and image information.

6. Apparatus according to claim 1, further comprising a plurality of communication conference apparatuses, and wherein each communication conference apparatus has a setting means which can set the direction of communication between its apparatus and each of the other communication conference apparatuses participating in the communication conference.

7. Apparatus according to claim 1, wherein said setting means includes a display unit, and wherein said display unit displays plural data corresponding to the participants of the communication conference.

8. A communication conference system comprising:

a plurality of communication conference apparatuses;

setting means for setting a direction of communication between the plurality of communication conference apparatuses participating in a communication conference, said setting means setting said direction at any time during the communication conference; and

connection means for connecting communication lines in accordance with the direction of communication set by said setting means.

9. A communication conference method for use amongst a plurality of communication conference apparatuses, said method comprising the steps of:

setting a direction of communication between one apparatus and each of the other communication conference apparatuses participating in a communication conference, the setting step setting the direction at any time during the communication conference; and

connecting communication lines among the plurality of communication conference apparatuses in accordance with the direction of communication set in said setting step.

10. A method according to claim 9, wherein the direction of communication is one of uni-directional transmission only, uni-directional reception only, and bi-directional communication.

11. A method according to claim 9, further comprising the step of displaying the other communication conference apparatuses participating in the communication conference.

12. A method according to claim 11, wherein the setting step is displayed in the display step.

13. A method according to claim 9, wherein the communication conference communicates at least voice and image information.

14. A method according to claim 9, wherein each of the plurality of communication conference apparatuses has a setting step for setting the direction of communication between said each apparatus and each of the other communication conference apparatuses participating in the communication conference.

15. A method according to claim 9, further comprising the step of displaying plural data corresponding to the participants of the communication conference.

16. A communication conference method comprising the steps of:

disposing a plurality of connected communication conference apparatuses;

setting a direction of communication between the plurality of communication conference apparatuses participating in a communication conference, said setting step setting said direction at any time during the communication conference; and

connecting communication lines in accordance with the direction of communication set in said setting step.

17. A computer readable storage medium for storing a computer program which causes a computer to perform the steps of:

setting a direction of communication between one apparatus and each of other communication conference apparatuses participating in a communication conference, the setting step setting the direction at any time during the communication conference; and

connecting communication lines among the plurality of communication conference apparatuses in accordance with the direction of communication set in said setting step.

18. A medium according to claim 17, wherein the direction of communication is one of uni-directional transmission only, uni-directional reception only, and bi-directional communication.

19. A medium according to claim 17, wherein the program causes the computer to perform the further step of displaying the other communication conference apparatuses participating in the communication conference.

20. A medium according to claim 19, wherein the program causes the setting step to be displayed in the display step.

21. A medium according to claim 17, wherein the communication conference communicates at least voice and image information.

22. A medium according to claim 17, wherein the program causes each of the plurality of communication conference apparatuses to have a setting step for setting the direction of communication between said each apparatus and each of the other communication conference apparatuses participating in the communication conference.

23. A medium according to claim 17, wherein the program causes the computer to perform the further step of displaying plural data corresponding to the participants of the communication conference.

24. A computer readable storage medium for storing a computer program which causes a computer to perform the steps of:

setting a direction of communication between a plurality of communication conference apparatuses participating in a communication conference, said setting step setting said direction at any time during the communication conference; and

connecting communication lines in accordance with the direction of communication set in said setting step.
