Abstract

A data broadcasting station transmits a multiplexed signal in which multimedia data encoded in a prescribed coding system are at least multiplexed in a broadcasting form. A file manager stores the multimedia data received by a tuner and decoded by a decoder in a storage device while creating management information therefor and registering it in a table. A browser requests of the file manager multimedia data to be referred to, and lets it be displayed on a monitor. The file manager increments/decrements a retention coefficient on the basis of a frequency of reference to the multimedia, and determines whether or not to delete each multimedia data stored in the storage device. Thus provided is a terminal device which can effectively utilize the capacity of the storage device without deleting multimedia data frequently referred to by the user.
