Video conferencing using white board

摘要

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.
