発明の名称 (英語) AUDIO AND VIDEO COMMUNICATION SYSTEM
発明の概要(英語) It is an object to obtain an audio and video communication system that can simultaneously carry out transmitting and receiving between a large number of nodes and that can flexibly deal with participation or release of a new node. The audio and video communication system couples many nodes with complete binary tree structure. When the complete binary tree structure composes a group, a root node links a new node to a left subordinate node connecting portion and adds 1 to weight information of the left subordinate node if the left subordinate node connecting portion is vacant; the root node links the new node to a right subordinate node connecting portion and adds 1 to weight information of the right subordinate node if the left subordinate node connecting portion is not vacant and the right subordinate node connecting portion is vacant; or otherwise and if the weight information of the left subordinate node is not more than that of the right subordinate, the root node inquires of the left subordinate node addition of a new node and adds 1 to the weight information of the left subordinate node; and if the weight information of the left subordinate node is more than that of the right subordinate, the root node inquires of the right subordinate node addition of a new node and adds 1 to the weight information of the right subordinate node.
