Abstract
An apparatus comprises: a unit that analyzes syntax of a bitstream corresponding to moving image data for which a minimum size of a unit according to decoding processing is defined and syntax of an accompanying bitstream that accompanies the bitstream; a unit that transforms high-level syntax obtained as a result of the analysis into new high-level syntax including a resolution that is lower than a resolution that the high-level syntax includes; a unit that transforms information which is obtained as a result of the analysis and is associated with a minimum size unit in the bitstream into information associated with a corresponding unit in the accompanying bitstream; and a unit that synthesizes, in accordance with syntax, the new high-level syntax and information after the transformation, and that generates a new bitstream.
