Abstract
A video communication system includes a video transmission terminal and a video reception terminal. In the video transmission terminal, a first control unit causes the video transmission terminal to be disconnected from a first network by controlling a first communication session control unit. After the video transmission terminal is disconnected from the first network, the first control unit causes the video transmission terminal to start an operation as an access point by controlling the first communication session control unit and causes the first communication session control unit to create a second network. The first control unit causes the first video session control unit to establish a video session with the video reception terminal.
