PROBLEM TO BE SOLVED: To distribute content data even if the state of terminal devices changes.SOLUTION: A content distribution system has a P2P distribution mode in which a plurality of terminal devices 2 are interconnected via a network so that the terminal devices 2 send and receive content data to and from each other, and a C/S distribution mode in which a storage device storing the content data is connected via a network 8 to each of the plurality of terminal devices 2 by a client-server method to distribute the content data to each of the terminal devices 2. Then, whether or not predetermined requirements for distributing the content data between the terminal devices 2 are met is determined, to switch between the P2P distribution mode and the C/S distribution mode according to the state of the terminal devices 2. |
