Abstract

When new software is stored in a server device (400), the software is stored in a preset free area (441B), and time information on time and date when the software is stored in association with information on the update file name in the free area (441B) to provide a new free area (441B). When a terminal unit (300) starts up, information on updating date fetched from the server device (400) when the software has been stored in advance, as well as information on update file names concerning software to be updated next is provided in information on update demand using If-Modified-Since of the HTTP to make the information transmitted to the server device (400). The server device (400) transmits the software to be stored in an update data area (441A) in the information on update file names having the time information more recent than the information on update data as software to be updated to the terminal unit (300).
