Abstract: Contents delivery to a mobile node which changes its existence position is executed from a delivery node with a high quality. Each cache server is located between each wireless LAN in which the mobile node can exists and a wired network. Each cache server delivers contents from the delivery node to the mobile node while storing the contents into a buffer. When the mobile node has moved, the mobile node transmits a moving notice to a cache server which is connected to a wireless LAN of the moving destination. Having received the moving notice, the cache server acquires the content in the buffer from a cache server which the mobile node had utilized before the moving. This configuration allows retransmission of the contents to the mobile node, thereby resulting in an enhancement in the delivery quality.

Abstract: A data processing method is provided whereby, even if communication delay occurs between computer game devices connected through a communication network, data is processed practically simultaneously between the respective computer game devices. When a computer game contest is carried out through a network having communication delay, before the game is started, the delay times between the game devices are found and, using these, synchronization of the time counted by the individual game devices is obtained. Then, during the progress of the game, the operating data signal is processed after the lapse of the longest delay time of the delay times between the game devices measured beforehand after it is generated. In this way, the operating data signal can be processed simultaneously in a plurality of game devices.
