Abstract:
In a system for providing information to a user through the use of a BS broadcast, information items can be displayed in an optimum order and the information can be deleted from or stored in a storage device in the optimum order. Attribute information showing information categories may be designated. When the information stored in the storage device is viewed, the number of times the information is viewed is counted for each category of the information by using the attribute information indicating the information category. A user access tendency is determined from the count value of the accessed category, and an access priority is determined from the user access tendency. Attribute information showing the priority of the information may also be designated. In this case, the access priority is determined from the attribute information indicating the information priority. When a list of the information stored in the storage device is displayed, it may be displayed in order from the highest access priority to the lowest. To assure a vacant area in the storage device, the information may be deleted in order from the information of the lowest access priority. When new information is stored in the storage device, the information of the highest access priority may be filtered and stored.
