Distributing information through an open network to many and unspecific clients being in different retaining situations with an information server

摘要

An information distribution system which distributes information including a large amount of data through an open network to many and unspecific clients being in different retaining situations. An information server includes a data production section, while the client includes a large capacity data retaining medium and a data retaining medium control section. When the information server distributes information through a network to the client, the data production section of the information server provides the data corresponding to the state of the data retaining medium control section of the client, whereas the client suitably uses the data existing in its own data retaining medium in utilizing the data from the information server. This enables effective data distribution.
