Such newspaper data are broadcast through the communication satellite. In each home terminal installed in the individual subscriber households, the newspaper data broadcasted by the edit/broadcast system from the branch office are received, decrypted by the use of a key obtained beforehand, and the newspaper data having the sort of newspaper and the date of issue thereof which agree with preset subscription contents are temporarily stored.
