Abstract:
1. A method of upgrading data installed in an apparatus, comprising: receiving a (n+1)th-order file obtained by iteratively bundling, from (n+1)=2 to x, an nth-order file including program data having an associated release level and program data having an associated release level that is earlier than the release level to which the program data included in the nth-order file is associated, into one file, until the (n+1)th-order file is obtained with (n+1) equaling x, n and x being positive integers, and x being greater than 2 and equaling a total number of release levels for which program data included in the (n+1)th order file is associated, so that the bundling is thereby performed in a release level by release level hierarchical manner; detecting an order m of a release level notified to the apparatus having data installed therein; de-bundling in a reverse of the release level by release level hierarchical manner, by a computer processor, the (n+1)th-order file as many as times corresponding to the order m of a release level to thereby obtain de-bundled data; and applying the de-bundled data to the apparatus.
