Abstract: It is made possible to update software appropriately. When additional software is installed, update management data for the additional software is generated. When the update management data for the additional software is attached to the additional software in advance, that data is used. If the update management data is not attached, cycles for confirming the presence of updates and the like are determined based on the nature of the software, and the update management data is thus generated. Then, the generated update management data is set in an update management table. The presence of software updates is checked for based on the cycles for confirming the presence of updates in the update management table.

Abstract: It is made possible to update installed software appropriately. A CE device stores an update management table in which are set, with respect to software bundled with the CE device, the names, IDs, version numbers, update cycles, and contact information (URLs of update data supplying servers) for making inquiries on the presence of updates. For example, assuming that everyday, when it is recognized that the time is past 10:00, there is a need to check for the presence of updates for software A, the CE device accesses a URL corresponding to software A, and makes an inquiry on the presence of updates.
