ABSTRACT:
In order to dispatch a newspaper to subscriber households through satellite communication, a newspaper edit/dispatch system in the head office of a newspaper publishing company electronically creates each paper sheet of national news section as first newspaper data, and transmits the first newspaper data to the branch offices of the company through a communication satellite. In a newspaper edit/broadcast system installed in each of the branch offices, the received first newspaper data and second newspaper data of a local news section are combined and edited into third newspaper data, the third newspaper data are encrypted, and the sort of newspaper and the date of issue thereof are affixed to the encrypted newspaper data. 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. Thereafter, the stored newspaper data are read and displayed in compliance with a subscriber's request.
