1. An information receiving apparatus comprising: a communication unit that receives distribution data sent from an information distribution server;a storage unit that stores the distribution data in a first storage area;an expandable memory that stores the distribution data removed from the storage unit;a control unit that requests the distribution data via the communication unit, whereinthe control unit removes the distribution data from the first storage area before requesting a download to the information distribution server and after a discrete number of distribution data files stored in the first storage area reaches a predetermined maximum number, and transfers the distribution data to a second storage area of the storage unit or to the expandable memory; andwherein the control unit determines whether a used storage capacity in the storage unit is greater than a predetermined value, and the control unit removes the distribution data from the first storage area and transfers the distribution data to the expandable memory when the used storage capacity in the storage unit is greater than the predetermined value, and removes the distribution data from the first storage area and transfers the distribution data to the second storage area of the storage unit when the used storage capacity in the storage unit is not greater than the predetermined value. 2. The information receiving apparatus according to claim 1, wherein when a first timing arrives, the communication unit receives the distribution data, and the storage unit stores the distribution data in the first storage area, and the control unit removes the distribution data from the first storage area and transfers the distribution data to the second storage area or to the expandable memory at a second timing that is a timing before the first timing. 3. The information receiving apparatus according to claim 2, wherein the first timing is a time of day that is designated by a server that performs distribution control of the distribution data. 4. The information receiving apparatus according to claim 3, wherein the second timing is a time of day that is before prescribed period from the first timing. 5. The information receiving apparatus according to claim 2, wherein the second timing is a time of day that is designated by a server that performs distribution control of the distribution data, and the first timing is the timing at which the control unit removes the distribution data from the first storage area and transfers the distribution data to the second storage area or to the expandable memory. 6. The information receiving apparatus according to claim 1, wherein the control unit performs a data existence confirmation process that confirms whether or not there exists distribution data to be acquired by the storage unit, and in the case of being judged to exist the distribution date to be acquired by the data existence confirmation process, the control unit removes the distribution data from the first storage area and transfers the distribution data to the second storage area or to the expandable memory. 7. The information receiving apparatus according to claim 1, wherein if another application is running when the control unit is to remove the distribution data from the first storage area, the control unit removes the distribution data from the first storage area after the completion of the running of the other application. 8. The information receiving apparatus according to claim 1, wherein the control unit inhibits the operation of other applications when the control unit removes the distribution data from the first storage area. 9. The information receiving apparatus according to claim 1, wherein when overwriting of the distribution data stored in the first storage area of the storage unit is not permitted, the control unit transfers the distribution data stored in the first storage area to the second storage area of the storage unit. 10. The information receiving apparatus according to claim 1, wherein when the distribution data stored in the first storage area of the storage unit has not been played back, the control unit transfers the distribution data stored in the first storage area to the second storage area of the storage unit. 11. The information receiving apparatus according to claim 1, further comprising a notification unit that notifies whether or not the data stored in the first storage area of the storage unit have been removed and transferred by the control unit. 12. The information receiving apparatus according to claim 1, wherein when overwriting of the distribution data stored in the first storage area of the storage unit is permitted, the control unit secures the storage area by deleting the distribution data. 13. A data downloading method in an information receiving apparatus that has a communication unit that receives distribution data sent from an information distribution server, comprising the steps of: storing the distribution data acquired via the communication unit in a first storage area of a storage unit that is determined in advance;in order to secure a storage area for the distribution data, removing the distribution data that are stored in the first storage area of the storage unit before a download request to the information distribution server is made and after a discrete number of distribution data files stored in the first storage area reaches a predetermined maximum number, and transferring the distribution data to a second storage area of the storage unit or to an expandable memory; anddetermining whether a used storage capacity in the storage unit is greater than a predetermined value; and removing the distribution data from the first storage area and transferring the distribution data to the expandable memory when the used storage capacity in the storage unit is greater than the predetermined value, and removing the distribution data from the first storage area and transferring the distribution data to the second storage area of the storage unit when the used storage capacity in the storage unit is not greater than the predetermined value. 14. An information receiving system comprising: a data distribution server that distributes distribution data;a receiving apparatus that has a communication unit that receives the distribution data distributed from the data distribution server;a storage unit that stores the distribution data in a first storage area;an expandable memory that stores the distribution data removed from the storage unit;a control unit that requests the distribution data via the communication unit, whereinthe control unit removes the distribution data from the first storage area before requesting a download to the data distribution server and after a discrete number of distribution data files stored in the first storage area reaches a predetermined maximum number, and transfers the distribution data to a second storage area of the storage unit or to the expandable memory; andwherein the control unit determines whether a used storage capacity in the storage unit is greater than a predetermined value, and the control unit removes the distribution data from the first storage area and transfers the distribution data to the expandable memory when the used storage capacity in the storage unit is greater than the predetermined value, and removes the distribution data from the first storage area and transfers the distribution data to the another storage area of the storage unit when the used storage capacity in the storage unit is not greater than the predetermined value.
