摘要：
Software-creating portion 11 creates update data and version-up data and supplies them to a receiver 20 through a delivery portion 13 or a server 15. The update data includes pieces of revision information of the version-up data after a period of time of each of their applications. Revision-information-processing portion 31 supplies revision information relative to software in a memory 34 to rewriting portion 33 and maintains remaining revision information. Data-revising portion 32 extracts revision information relative to the version-up data that is supplied through interfaces 25 and 26 from revision information maintained in the revision-information-processing portion 31, revises it to the latest one with it reflecting the version-up data, and then supplies it to the rewriting portion 33. The rewriting portion 33 rewrites the software in the memory 34 with the revision information and the version-up data thus supplied. This allows the software to be rewritten in which its latest condition is always realized.
