Abstract: To provide an information acquisition system that allows specific information related to an object item, etc., which is exhibited at an exhibition site, to be acquired concurrently with taking an image thereof by a picture taking device. An ID transmitter 30 provided to an object 20 transmits object ID that enables identification of the object. When an image of the object 20 is taken at a position where the object ID can be received, an image taking device 10 obtains the object ID together with the taken image. The image taking device 10 transmits the obtained object ID to an information server 40. The information server 40 returns source information (for example, a URL where information such as product performance and a price related to the object can be acquired) corresponding to the received object ID to the image taking device 10. The image taking device 10 stores the received source information together with the taken image.

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.
