Abstract
A control apparatus includes a reception unit which receives distribution data which contains compressed update data and a header which includes information to designate any one of a plurality of update systems, a decompression unit which decompresses the update data from the distribution data received by the reception unit, and a restoration unit which restores a new program after updating according to an update system designated in the header using the update data decompressed by the decompression unit. The decompression unit switches a decompression method when the update data is decompressed on the basis of the update system designated in the header.
