PURPOSE:To select a transfer procedure depending on a data transfer form by providing a transfer form identification means identifying the data transfer form between communication terminal equipments and a transfer procedure selection means selecting automatically the data transfer procedure to the terminal equipment. CONSTITUTION:A data transfer form identification means 1 identifies whether a data transfer form of the communication terminal equipment for video conference terminal equipments is 1:1 data transfer between one video conference terminal equipment and other video conference terminal equipment or 1:n data transfer among one video conference terminal equipment and two or over of other video conference terminal equipments. A transfer procedure selection means 2 employs a confirmation form data transfer procedure in the case of the 1:1 data transfer form based on the identification by the transfer form procedure and employs a non-confirmation form data transfer procedure in the case of the 1:n data transfer form automatically. Thus, in the case of data multiple address communication using an inter-multi-point communication controller, no protocol error is caused. |
