PROBLEM TO BE SOLVED: To enable a user to hear the specific contents of information at any time at any place by using a user interface which is functionally connected to a cipher decoder and a storage which has an input port connected to an output terminal of the cipher decoder and also which has an output port, etc. SOLUTION: A user interface which is functionally connected to a cipher decoder is prepared together with a storage which has an input port that is connected to an output terminal of the cipher decoder and also which has an output port, etc. A user interface 40 of this receiver inputs a command to a microcontroller 20 via a line 42 and decides a specific item of the data sent from a storage 28 that is to be heard. The received information are sorted and stored in a hierarchical data base contained in the storage 28 under the control of the microcontroller 20 and also accessed. In other words, a user shows an item selected from a menu and can access the information via the interface 40. |
