Abstract
Abstract A receiving apparatus has a database containing broadcasting-station information. A controller in this receiving apparatus determines based on the storage contents of a memory that a reception frequency set to be tuned matches with reception frequencies of a plurality of broadcasting stations in a predetermined geographical range when the reception position lies within the predetermined geographical range. When the reception of broadcast waves is detected in the tuning operation, the controller determines that the set reception frequency is the reception frequency of a multistation. When the set reception frequency is determined as the reception frequency of the multistation, the controller selects information associated with one of a plurality of broadcasting stations which uses that reception frequency, based on the storage contents of the memory and sequentially stores the selected broadcasting-station information together with the reception frequency as the reception history of the multistation in association with the predetermined geographical range.
