Abstract

PURPOSE:To prevent the transmission of same content of information to different users, by transmitting only offered information added with a key word collated with the key word of ussage request from an information stream through pick up and recording charging information. CONSTITUTION:Information received from a terminal 3 of an information offerer is stored once to a large capacity of a storage device 9 through the control of a control section 8 by an information receiver 4 in an exchange station 1. The control section 8 reads out information from the storage device 9 and stores only a catalog included in the information stream with a discriminating code to an information selector 5. When a terminal 6 of an information user transmits a request of catalog transmittal of offered information desired to an exchanger 1, the catalog transmittal request and catalogs stored in the device 5 are collated and the offered information requested is transmitted from the exchange station 1 and charging information is transmitted and recorded with the information selector 5.
