A system and a method for a video stream based on user presence in an IP network are provided to check the state of each IP terminal and the user presence to identify an optimal IP terminal, thereby providing a video data stream to the optimal IP terminal. IP(Internet Protocol) terminals(100) set user presence including the presence information of a user indicating a state when video data stream is possible according to user setting or automatic setting and a user can not view video data, and transmits the state information of the user. A video stream server(200) checks the user presence information and the call state information of the IP terminals provided from the IP terminals and determines whether to stream the video data of each of the IP terminals.
