摘要： A portable information terminal includes a controller configured to control a communication interface to transmit a charging permission response to a broadcast receiving apparatus in response to a charging permission request data transmitted when a broadcasting program that a user of the broadcast receiving apparatus desires to view contains an asset that requires charging. The charging permission response is allowed to be transmitted when positional information indicates that the portable information terminal is positioned inside of a predetermined positional range and apparatus identification information in the charging permission request data, by which the broadcast receiving apparatus is allowed to be identified, coincides with apparatus identification information stored in a memory. The controller controls the communication interface to transmit a charging denial response to the broadcast receiving apparatus when the positional information indicates that the portable information terminal is positioned outside of the predetermined positional range.
