Abstract

In a video conference system and method, a first terminal and second through Nth terminals maintain a session for a conference. The first terminal prevents an input of further information to the white board by the second through Nth terminals during a set time period from an input of information to the white board and the second through Nth terminals transmit further information, input during a buffering mode selected in an unlocked state, to other terminals participating in the session upon the input of information to the white board being allowed after the set time period has elapsed.

Claims

1. A terminal participating in a session maintained by at least two terminals in a video conference system using a white board, the terminal comprising:

a controller, the controller adapted to;

request other terminals participating in the session to prevent input of further information to the white board during a set first time period from when information has been input to the white board by the terminal; and

to select a buffering mode and to transmit further information to the other terminals participating in the session upon the input of information to the white board being allowed after a set second time period has elapsed upon receiving the request to prevent input of further information to the white board during the set second time period.

2. The terminal of claim 1, wherein the controller is adapted to encode the information input to the white board and the further information input during the buffering mode in extensible Markup Language (XML), and to transmit the encoded information to the terminals participating in the session.

3. The terminal of claim 1, wherein the controller with priority is adapted to transmit the further information input during the buffering mode to the other terminals participating in the session after the set second time period has elapsed.

4. A video conference system using a white board, the system comprising:

a first terminal and second through Nth terminals adapted to maintain a session for a conference;

wherein the first terminal is adapted to prevent input of further information to the white board by the second through Nth terminals during a set time period from an input of information to the white board; and

wherein the second through Nth terminals are adapted to transmit further information, input during a buffering mode selected in an unlocked state, to other terminals participating in the session upon input of information to the white board being allowed after the set time period has elapsed.

5. The system of claim 4, wherein the first terminal is adapted to encode the information input to the white board in extensible Markup Language (XML) and to transmit the encoded information to the other terminals participating in the session, and wherein the second through Nth terminals are adapted to decode the information encoded in XML and output the decoded information.

6. The system of claim 4, wherein the second through Nth terminals are adapted to encode the further information in extensible Markup Language (XML) and to transmit the encoded information to the other terminals participating in the session, and wherein the first terminal is adapted to decode the information encoded in XML and to output the decoded information.

7. The system of claim 4, wherein the second through Nth terminals with priority are adapted to transmit the further information, input during the buffering mode, to the other terminals participating in the session upon input of information to the white board being allowed after the set time period has elapsed.

8. A conference method of a terminal participating in a session maintained by at least two terminals in a video conference system using a white board, comprising the step of:

requesting to prevent input of further information to the white board by other terminals participating in a session during a set time period from when information is input to the white board.

9. The method of claim 8, wherein the step of requesting to prevent the input of further information to the white board by the other terminals participating in the session comprises the steps of:

encoding the information input to the white board in XML; and

transmitting the encoded information to the other terminals participating in the session.

10. A conference method of a terminal participating in a session maintained by at least two terminals in a video conference system using a white board, the method comprising:

detecting whether a buffering mode has been selected when another terminal participating in the session has been requested to prevent input of information to the white board for a set time period;

receiving and storing information upon the buffering mode being selected; and

transmitting the stored information to the other terminals participating in the session upon input of information to the white board being allowed after the set time period has elapsed.

11. The method of claim 10, wherein transmitting the stored information to the other terminals participating in the session comprises encoding the information in extensible Markup Language (XML).

12. The method of claim 10, wherein transmitting the stored information to the other terminals participating in the session comprises obtaining priority and transmitting the stored information to the other terminals upon input of information being allowed after the set time period has elapsed.

13. A conference method of a video conference system including a first terminal and second through Nth terminals maintaining a session for a conference, the method comprising:

the first terminal requesting prevention of an input of further information to a white board during a set time period from when information has been input to the white board; and

the second through Nth terminals receiving and storing further information upon a buffering mode being selected in a locked state, and transmitting the further information to other terminals participating in the session upon input of information to the white board being allowed after the set time period has elapsed.

14. The method of claim 13, further comprising:

the first terminal encoding the information input to the white board in extensible Markup Language (XML) and transmitting the encoded information; and

decoding, at the second through Nth terminals, the information encoded in XML and outputting the decoded information.

15. The method of claim 13, further comprising:

the second through Nth terminals encoding the further information in extensible Markup Language (XML) and transmitting the encoded further information to the other terminals participating in the session; and

the first terminal decoding the further information encoded in XML and outputting the decoded information.

16. The method of claim 13, wherein transmitting the further information to the other terminals participating in the session comprises allowing the second through Nth terminals with priority to transmit the further information, input during the buffering mode, to the other terminals participating in the session upon the input of information to the white board being allowed after the set time period has elapsed.
