A data reception apparatus includes: a receiver that receives first compressed data from a data transmission apparatus and second compressed data from the data transmission apparatus; and a hardware processor that: starts decompression processing of the first compressed data; calculates a scheduled completion time point of the decompression processing of first unit compressed data, and calculates a scheduled completion time of decompression processing as decompression processing of second unit compressed data; and executes processing for determining, as data to be decompressed that is compressed data to be subject to the decompression processing, unit compressed data presumed that the decompression processing is to be complete earlier out of the first unit compressed data and the second unit compressed data, wherein the hardware processor executes the decompression processing of the unit compressed data determined to be the data to be decompressed.
