Abstract: PROBLEM TO BE SOLVED: To properly distribute information files of a large capacity to recipients while saving troubles to the recipients. SOLUTION: An information distribution control means 140 of the information distributor 100 of this invention reads an information file stored in an information file storage means 110 and a distribution schedule stored in a distribution schedule storage means 120 to generate information data for transmission. A broadband communication control means 150 or a narrow band communication control means 160 selected depending on contents of the generated information data transmits the generated information data via a selected communication channel. A receiver 200a (200b) uses a broadband reception control means 210 (narrow band communication control means 220) to receive the information data. An information extraction control means 230 acquires the distribution schedule and references this distribution schedule to extract desired information from the received information data. A reception data storage means 240 stores the distribution schedule and the extracted information. Furthermore, a display means 250 displays the extracted information according to the information extract control means 230.
