Connection state control device, connection state control method, and connection state controlling program

摘要

A connection state control device is provided that can promptly perform a reproducing operation by smoothly switching channels at each node and reduce the load on the management server in a case where operations are performed so as to sequentially change distribution information to be received at each node in a network system having a tree structure. A node receives content being distributed over a network, and performs an operation of reproducing the received content. When the node is to receive different content being distributed over a different network, the node is connected to the different network. After that, the node receives and reproduces the different content. The node continues to receive the original content but suspends the operation of reproducing the original content after connected to the different network.
